Brief:
In checkin' me club's flight cards for t' last 2.5 years, I find that thar have been 8 MMX launches. Blimey! All o' them were done by me. Well, blow me down! I have tried t' see if thar was any interest in an informal MMX contest o' some type on several occasions and thar be not. Ahoy! In delvin' a bit deeper, arrr, I learned that MMX was nay disdained because of its diminutive size, me hearties, it was shunned because o' t' hassle, me hearties, real and perceived, shiver me timbers, me bucko, o' flyin' them. Aye aye! That was an attitude I shared myself. Ya scallywag! Every time I thought about buildin' or flyin' one, me bucko, I usually gave it up as too much hassle.

That is especially true o' t' ground support equipment. Avast! T' silo launchers are problematic and I have had only one good launch off o' one. Begad! T' rest o' t' time I have had t' kludge somethin' together, me hearties, cross me fingers and hope it works. Blimey! It sometimes even does.

This is nay t' say that thar are nay some great MMX GSE ideas out there. Begad! Blimey! There are. Avast, me proud beauty! Begad! Blimey! They just don't strike me as worth t' effort. Well, blow me down! I finally decided t' see if I could design somethin' t' take some o' t' hassle out o' it and make it fun. Blimey! Blimey! In effect, with a minimum o' effort, ya bilge rat, I want t' be able t' treat an MMX rocket like any other. Ya scallywag! Begad! Blimey! Go out t' the assigned pad, me hearties, hook it up, walk away and have reasonable confidence that t' rocket would launch. Well, blow me down! Blimey! I wanted t' be able to do this without lengthy preparation o' special consumables. In order t' do it, ya bilge rat, I was willin' t' invest some time, effort and loot into makin' such a system.

T' basics that I wanted t' accomplish are these:

• Build t' project with readily availible parts; no machinin' or milling.
• Be able t' use any o' t' common igniter options without havin' t' switch gear.
• Be dependable; t' same ration o' successful launches as will t' bigger gear.
• No hassle, me hearties, perceived or real.

Construction:

T' first step in this grand project be t' get out an MMX igniter, measure it and make a drawin' o' it in Autocad. Aye aye! I measured t' 1/16" and estimated t' 1/32" I think it will be good enough for me purposes. Aye aye! Ya scallywag! I wanted t' DWG files o' t' various igniters I want t' plan for t' use as blocks in t' drawin' files help me draw up t' ignition system. Well, shiver me timbers, blow me down! I also wanted t' have a half decent chance o' havin' t' thin' work when I got through. Ya scallywag! I also cracked open t' plastic case and made a drawin' o' t' naked igniter. Well, blow me down! With that done, I could start drawin' up the head.

I had liked what I had seen o' several ideas that used a slot t' support t' igniter and that was a part o' the idea as well. Avast! That bein' t' case, arrr, t' first thin' was t' come up with t' arm that provided t' support. Ahoy! Well, blow me down! I decided on 1/4" plywood as t' basis for t' framework. Arrr! I picked it for dimensional stability and because it is an insulator. Most important, though, ya bilge rat, matey, ya bilge rat, it has laminations oriented at different angles so that shear should nay become an issue. Aye aye! This be because I planned on a relatively skinny support, me hearties, for reasons which will later become apparent.

I opened up Autocad and drew up a support arm that had a slot that was just a touch bigger than t' plastic encased igniter. At this point I did nay concern myself with length, only t' part that would support t' igniter. Begad! Well, matey, blow me down! Blimey! I then printed out this simple drawing.

Although t' support beam would ultimately be o' plywood, I did nay use plywood at this stage. Ahoy! I chose instead a scrap o' 1/4" balsa since it would be easy t' whittle on and adjust and because it happened t' be handy. The template be trimmed a bit and then applied t' t' balsa with a glue stick. Arrr! T' rough piece was then taken t' t' belt sander and t' profile was trimmed down t' t' outer edges o' t' template. Arrr! Avast! With t' outer edges takin' place, a razor knife was used t' carve out t' igniter slot.

Later that night, arrr, it was time t' examine t' first fruits o' t' project and I spread me stuff out on the kitchen table after t' Mrs. Arrr! had gone t' bed. Blimey! I put in t' plastic igniter ans was glad t' see it fit; with me doing t' measurin' and cutting, such things cannot be assumed. Blimey! I also test fitted t' stripped down, ya bilge rat, me bucko, shiver me timbers, paper clad igniter and it fit as well.

One o' t' problems I had experienced with other MMX systems was t' attachment o' t' microclips. Begad! Ahoy! My scheme was t' get rid o' t' "micro" altogether and replace it with "macro". Begad! Ahoy! I found a plastic clamp at Lowes that seemed t' fit t' ticket and tried it on t' support t' plastic igniter. At first blush it seemed t' work. Looking at it from t' top, me hearties, though, thar be a slight problem. Ya scallywag! T' grips on t' clamp were just a touch wider than t' slot. For t' ultimate plan, me hearties, they needed t' fit flat within t' slot.

Before doin' any adjustment, though, ya bilge rat, me bucko, I wanted t' try it with t' naked igniter. Aye aye! Blimey! I slipped it into place, oriented 90 degrees from t' way t' plastic one had been, and made sure t' leads extended on either side o' the support. Begad! Aye aye! Blimey! T' clamp be then placed, much lower down this time, ya bilge rat, pinnin' t' leads t' either side o' t' support arm. Ahoy! Well, blow me down! Blimey! I then spent some time fussin' with it. Key t' makin' me scheme work was t' degree o' stiffness o' t' igniter in this orientation. Begad! Begad! Blimey! It seemed t' me that t' clamp be sufficiently tight t' hold it in place without any wiggling.

With t' information I had gotten thus far, me hearties, I went back t' Autocad and widened t' slot by 1/32" on each side.

To provide electrical contact, matey, matey, I intended t' use a pair o' brass pieces, ya bilge rat, one on each side o' t' launch head. each would be primarily vertically oriented so that a naked or standard ingniter could be set in place with one lead clamped t' either side. I also intended t' fold a small piece o' brass over t' top t' catch t' leads on t' classic MMX igniter.

I went into Autocad and drew up a plan for t' brass pieces assumin' that I would be usin' 1/2" wide brass. T' lines for foldin' and cuttin' were marked interchangeably. A copy was then printed, cut out and taped t' a piece of 1/2"x0.016"x12" piece o' brass. Begad! Begad! A cutoff disk on a Dremell tool be then used t' cut t' piece t' length and slice t' part that would be folded back. Avast! A pair o' pliers was then used t' make t' bends and folds. Well, blow me down! T' folds were nay completely bent into shape under t' theory that some finaglin' would be needed and I wanted t' fatigue the metal as little as possible. An identical piece was then cut and formed and t' pair was test fitted into t' head.

Solderin' is nay one o' me strong skills, and that's puttin' it kindly. Begad! Blimey! Even so, I felt obligated t' provide the electrons with a path t' get t' t' brass contacts. I took a length o' speaker wire, stripped t' ends and then soldered a lead t' t' back o' each o' t' contact plates.

In order t' accommodate t' solder on t' backs o' t' contact plates and allow them t' lie flat, shiver me timbers, shiver me timbers, ya bilge rat, I had to excavate a cavity on either side o' t' head. It be done by trial and error with an ambiguous head on t' Dremmel. Avast, shiver me timbers, me proud beauty!

Since this be merely a proof o' concept prototype, arrr, I did nay take t' trouble t' fasten t' plates t' t' head in a "good" manner. Ya scallywag! Begad! Instead, me hearties, shiver me timbers, shiver me timbers, I just epoxied them into place and clamped them t' set. Begad! Blimey! This proved t' be a mistake since some o' t' epoxy developed and unhealthy relationship with t' clamp and t' removal o' said clamp distorted things.

Several tests were made with t' prototype and I found that t' concept did work but that thar were some problems with execution. Blimey! Blimey! Aside from t' nay so durable balsa used as t' head, arrr, matey, t' method o' attachin' t' wires t' the plates and t' plates t' t' head were also problematical. Avast! Blimey! As I considered how t' deal with these issues, I turned my attention t' t' "guts" o' t' project.

My intention all along be t' develop a series o' racks for various types o' rockets me club may fly. Arrr! Well, arrr, blow me down! I wanted t' standardize as much o' t' design as possible. Ahoy! I had decided early on that each rack would be mounted on an identical steel sawhorse. Avast! T' that would be fastened a "box" that would contain whatever wirin' was needed and on t' "box" would be mounted t' individual launch heads. Begad! After lookin' at lots o' different options for the "box", I decided t' try usin' NEMA type 1 electrical troughs. Blimey! Avast, me proud beauty! For t' MMX rack, I ordered a 4"x4"x48" trough with a hinged cover and a pair o' endcaps t' go with it. Ahoy! Blimey! I specified that I did not want knockouts.

I wanted t' go ahead and prime t' box and knew that me normal Kilz primer would nay be a good choice. Based on some advice, ya bilge rat, I purchased Dupli-Color automotive white primer and went t' work spraying. Ya scallywag! Begad! I smartly learned that while t' primer adhered well, me bucko, a lot was needed for full coverage. Well, blow me down! I emptied a can and still plenty left t' go.

Rather than spend more in primer than t' box cost, me bucko, I decided t' brush on some gray primer made for metal applications. I bought a gallon since I have several projects on which t' use it and because it was nay available in smaller sizes. Arrr! I brushed on t' first coat and let it dry overnight. Ahoy! T' end caps were painted as well.

T' first coat o' gray primer was rather streaky (but much better over t' surfaces that had received t' white spray primer first) and a second coat be applied t' all t' pieces. Avast! It came out much better.

A day after t' second coat o' primer be applied, I mounted t' end caps. Well, blow me down! Avast, ya bilge rat, me proud beauty! Each one required 3 bolts I used 1/4x3/4 along with a lock washer. Begad! When in place, ya bilge rat, t' caps greatly increased t' rigidity o' t' trough.

As mentioned before, shiver me timbers, ya bilge rat, t' base o' me system was t' be a commercially available steel sawhorse. Begad! Blimey! I chose t' one made by Task Force because it seemed sturdy, already had some holes drilled about where I would want them, had adjustable length legs and because it happened t' be what was for sale at me local Lowes.

T' larger holes in t' sawhorse turned out t' be just right for 5/16" bolts. Begad! Ahoy! I assumed that each base would have a pair o' such bolts t' fasten t' box above. Ahoy! I saw a potential problem, ya bilge rat, though o' t' bolt slippin' out through t' hole while hands were occupied handlin' t' box. I kept askin' about some sort o' "retainer" to keep them from slippin' out. Avast, me proud beauty! Blimey! I had just about decided t' try and fit a little rubber O rin' on t' shance t' keep it from slippin' through when somebody mentioned an "E clip". Begad! That turned out t' be just t' ticket. T' bolt was slipped through t' hole and t' clip was popped into place at t' base. Ahoy! It did what I wanted and freed me hands from havin' t' keep t' bolt in place while fumblin' around with t' box.

To hold t' box onto t' sawhorse mounted bolts, I wanted t' use wingnuts that could easily be removed. Arrr! I also added a fender washer t' t' system t' spread t' load out a bit if t' assembly were t' be picked up by t' built in handle on t' sawhorse. Well, matey, blow me down! Since I was nay yet ready t' mount t' box, ya bilge rat, I just stored t' washers and wingnuts in their eventual place o' residence.

T' bolts on t' base are spaced 30" apart so I drew a light line down t' centerline o' t' bottom o' the trough and made marks for t' bolt holes at that spacing, matey, me bucko, centered betwixt t' ends. T' holes were then drilled with a 5/16 bit.

T' system was now ready for me t' test fit t' box on top o' t' support. Arrr! As such, matey, I undid t' wingnuts and removed t' fender washers and was pleased t' see that t' bolts did nay then fall out. Ya scallywag! So far, so good. Arrr! I set t' box on top and t' holes lined up t' t' bolts...mostly. There was a bit o' tightness at one end and t' box was forcing t' bolt t' lean. For grins, I put on t' washers and wingnuts and tightened it down part o' t' way. Avast, me proud beauty! I then lifted the rack by t' carryin' handle and it seemed t' idea be sound so far but needed a little more work.

One o' t' things I noticed is that t' bolt stuck up farther than I liked on t' inside o' t' box. Ahoy! I decided t' use a 3/4" length instead o' t' full inch. Begad! Accordingly, ya bilge rat, I popped t' e-clip off and substituted a shorter bolt. Begad! I had also noticed that t' bolt tended t' turn as I tried t' tighten t' wingnut. Begad! Begad! T' remedy that I added a star lock washer under t' bolt head.

Another problem I noticed is that I must have gotten t' spacin' for t' holes in t' box just a wee bit off. Ahoy! Well, blow me down! On bolt be tilted t' an angle when t' box was put one and t' nut could nay be completely tightened. Avast! I tried t' fit a nibbler into t' hole but t' head would nay quite fit so I took a round file and opened it up a bit. Aye aye! I was then able t' slip t' head o' t' nibbler in and took a single bite out o' t' hole t' let t' bolt sit more upright. Avast! T' box was then put back into place and this time it went down flush and t' wingnut took held it flat.

Another thin' I wanted t' change was t' screws that held t' hinged cover closed. Begad! Avast, me proud beauty! These were simple screws that I KNEW would pop out and be lost in t' field since I wanted t' be able t' use t' box for storage. Begad! As such, I ordered some knurled headed screws from Grainger t' replace them. Begad! I also ordered some split rings t' keep t' screws from pullin' all t' way out o' t' lid. When they came in, all three screws on t' cover were replaced.

I had decided that t' rack would have 6 launch pads spaced 8" apart. Ahoy! This was tighter than I liked but I didn't want t' box t' be longer than 48" longs for transport. Avast, me proud beauty! I drew a line down t' center o' t' cover and marked 6 places evenly spaced betwixt t' 2 ends. Blimey! I then drilled 5/16" holes at each station.

T' basic support o' each o' t' heads be t' consist o' a 2" long, 5/16" bolt. I added a washer to distribute t' force and a lock washer t' keep t' bolt from spinnin' as t' exposed side is manipulated. Begad! T' hold the bolt fast from t' top side, shiver me timbers, another washer and and nut were placed and t' assembly tightened down. Ya scallywag! Ahoy! A pair o' nuts was then put onto t' upper side and turned down approximately halfway. T' purpose o' t' twin nuts is t' be able t' lock them against each other and set t' height. Blimey! Next came a pair o' SAE washers and a wingnut. Blimey! T' washers are t' sandwich t' actual launch head. Aye aye! This process was repeated for all six stations.

As t' actual base and box were bein' built, matey, matey, I kept workin' on t' design o' t' launch head, makin' some changes based upon t' original prototype. Arrr! On t' next set o' prototypes, I used plywood, a much more durable product than balsa but t' trade off is that it does nay whittle as easily t' make adjustments. Avast, me proud beauty! I printed up new templates for 10 heads rough cut them with a jigsaw, me hearties, sandin' them down t' t' outer profile. Avast! Avast, me bucko, me proud beauty! T' notch for t' igniters was rough cut with t' same jigsaw; thar was little uniformity except that I (mostly) stayed within t' lines. Finishin' down t' the lines was done with a combination o' X-acto, file and sandin' stick and eventually, arrr, they were all pretty standard.

An issue that had nay been addressed in t' previous prototype be t' securin' o' t' MMX launch rod. Blimey! I wanted somethin' more secure than just a hole drilled into t' plywood. Aye aye! Ahoy! I wanted t' head t' retain t' rod. I came up with an idea and ran it past several people with much more mechanical experience than me. Avast, me proud beauty! Begad! T' answer I kept gettin' was that "it might work; try it and see." That turned out t' be some work and an excuse t' acquire some new tools.

I bought a 3 foot length o' 1/8" brass tubin' t' receive t' rods. Ya scallywag! A cut off wheel on a Dremmel tool was used t' cut 10 pieces, each an inch and a quarter long. Begad! There was some sloppiness here and some turned out longer and some shorter but, matey, in general, their length was t' same as t' depth o' t' launch head.

A guy at Quality Fasteners, me hearties, a local screw and bolt place, arrr, gave me t' idea for securin' t' brass tube in place. Up until now, shiver me timbers, me mind had gone off in a completely different and much more complex direction. Well, blow me down! Begad! For each piece o' brass, I obtained 2 nylon harnesses that seem t' be designed t' retain wire. Blimey! Each be sized t' hold an 1/8" rod and be held in place with a #8 bolt or screw. Aye aye! Avast, me proud beauty! I place them by eye and used a pen t' mark t' holes for drilling. Begad! T' keepers were then bolted into place with nylon lockin' nuts holdin' them fast on t' opposite side. Arrr! I found that by not tightenin' them down all t' way at first, I could slip in t' brass tube and eyeball it into place. Ya scallywag! Arrr! When tightened, t' keepers work together t' keep it straight.

T' next part was t' tricky and t' iffy part. I wanted a set screw that could be turned by hand that would keep t' MMX rod in place. Well, blow me down! Aye aye! T' smallest suitable screw I could find was a #2-56 which had a little head on it that I could thumb tighten. Begad! Avast! What I did nay know is if I could drill t' holes through t' brass and have enough material to hold a thread. Arrr! Added t' that, shiver me timbers, I had never used a tap or die in me life.

I set up t' proper drill in me Dremmel press and realized that I could much more easily keep t' brass tubing straight by leavin' it mounted t' t' launch head. Strangely enough, me bucko, me bucko, I managed t' drill each o' those little hole without havin' t' cut any more tubing. Then came t' moment o' truth. Ya scallywag! Aye aye! I took out t' tap and started t' thread it into t' hole. Ya scallywag! It seemed t' bite and t' threads seemed t' take. Avast, me proud beauty! Well, me bucko, blow me down! I removed t' tap and tried t' screw. Begad! It threaded fine. Best o' all, it securely held t' MMX rod in place!

To mount t' launch heads onto t' racks, I decided t' make a mount o' o' 1/8" x 3/4" aluminum angle (L1/8x3/4x3/4). Avast, me proud beauty! Avast! I purchased a 36" length from Lowes and marked sections 2.5" long. T' first o' t' 10 mountin' brackets was cut out with a hacksaw. That got old very smartly and a Dremmel cutoff wheel was used t' slice t' rest.

Considerable time was spent with t' 10 "2nd prototypes" movin' t' hardware around and tryin' t' come up with what I thought o' as t' best arrangement. Begad! Finally, I got things settled in me mind and took measurements to transfer t' a CAD file for t' final template. Blimey! I generated one set o' templates for t' launch head and another for the mountin' brackets. Begad!

T' final launch head template was printed out and applied t' t' 1/4" plywood with a glue stick. Ya scallywag! As before, arrr, ya bilge rat, a jigsaw was used t' cut out t' rough blocks. Also as before, me hearties, a sander was used t' reduce t' rough blocks to t' final external outlines. Ya scallywag! T' igniter notches were rough cut with t' jigsaw and finished with files and sanding sticks.

Similarly, templates for all t' mountin' brackets were printed, cut out and taped into place on t' aluminum brackets. Well, me bucko, blow me down! All o' t' 5/32" holes t' mount t' brackets t' t' heads were then drilled. When that be done, arrr, I randomly tried a few o' t' brackets with a few o' t' heads t' make sure things were linin' up as I thought they should. Ahoy! It was then time t' drill t' holes for t' 5/16 mountin' bolts. Since these were quite a bit larger in diameter, I drilled a small pilot hole first. Ahoy! T' full diameter holes were then drilled. Avast, me bucko, me proud beauty! With that done, t' mounting brackets were complete and t' templates and tape were stripped away.

T' heads had all o' their 5/32" (#8) holes drilled followed by t' 7/64 (#4).

I had always intended t' paint this system and decided that t' first coat would go on before t' next step in assembly. Aye aye! Blimey! T' templates were stripped off and balsa filler coat be applied t' all o' t' plywood heads t' fill some of t' grain. Arrr! Blimey! All o' t' brackets were then primed with white Dupli Color primer. Aye aye! Blimey! T' launch heads were likewise primed. Everythin' then got sprayed with a coat o' red.

When t' paint dried, me bucko, ya bilge rat, things began t' move more quickly, especially since most o' what was left just involved assembly line acts that had been done before. Arrr! T' clips t' hold t' rod receivers were loosely bolted into place. Arrr! The receivers that had been fabricated for t' second prototype were retained and fit into t' clips. Begad! Once they seemed straight, t' bolts were tightened down. Blimey! T' mountin' brackets were then bolted into place and all that be left be to take care o' t' electrodes, shiver me timbers, t' launch rods and put it all together.

T' key t' me whole system was t' electrode system t' handle igniters for MMX. Blimey! Begad! OF course, this is where I ran into most o' me problems. Well, blow me down! My first prototype had worked for ignition and holdin' t' igniters in place but be nay very durable, me bucko, was unwieldy an and a royal PIA t' mass produce. Avast, me proud beauty! I had intended for t' electrodes t' be connected directly to t' launch system in place o' t' normal lead wires. One o' t' revelations that came t' me is that this would violate me intention o' interchangeability betwixt racks; in a pinch, shiver me timbers, I would nay be able t' use t' MMX leads for another pad or vice versa. Avast! Then I realized thar was no reason t' get rid o' t' electrodes. Avast, shiver me timbers, me proud beauty! I would just have t' clips connect them. Ya scallywag! That way t' clips would still be present for other sorts o' launches if needed.

I rethought t' electrodes and be frustrated by tryin' t' electrically isolate t' pair. Avast! I had visions o' a sheathed, me bucko, me bucko, insulated bolt t' hold them in place but smartly found that thar be nothin' existin' that I could find to use. Avast! I did nay want t' rely on wood screws that might pull out and t' project languished while I tried t' figure what t' do. Ya scallywag! Eventually, me bucko, me hearties, I realized that t' electrode could be bolted on just one side and still stay in place. Aye aye! Begad! I just added a bit more material t' one side for t' holes. Begad! Since t' electrodes would go on opposite sides o' t' head, they would clear each other. I drew up a template and printed it out.

Another change I made on t' modified electrode be t' choose a thinner gauge o' brass. Ya scallywag! Begad! Instead o' usin' strips, this time I bought a sheet o' 0.01" thick stock. Aye aye! I taped t' template t' t' brass sheet. Arrr! Ahoy! I tried several different methods o' cuttin' t' brass along t' lines, arrr, me hearties, mostly involvin' a Dremmel cutoff wheel with poor accuracy results. Blimey! I then found t' me surprise that kitchen shears worked better than anythin' else as long as SHE WHO MUST BE OBEYED did nay catch me usin' them.

T' brass blank with template affixed was then set on a piece o' scrap (an old head prototype) and a Dremmel drill press was used t' pierce t' three holes in t' electrode. Arrr! I should mention here that two o' t' hole were for mountin' and t' bottom hole is t' give t' igniter clips a better grip for connecting.

With t' piece drilled, some needle nose pliers were used t' bend some contacts for t' top surface o' the electrodes. Ya scallywag! Ahoy! I learned that t' brass was too soft t' want t' bend nicely along t' marked lines. Begad! T' electrode was then mounted onto t' head with some #4 brass screws and nuts. Ahoy! Several things became immediately apparent. Avast! My drillin' of t' holes with a hand drill had been sloppy and t' mountin' holes were nay in line; t' flexin' o' t' drill bit I had noticed in t' press was enough t' throw things off; and it looked like I be goin' t' have t' start again.

After apologizin' t' t' cat for me strin' o' expressions learned in t' USN, I tried another blank and got about t' same results. Aye aye! This time I noticed that t' bit had slipped and flexed even more than before. With me club launch fast approachin' and t' promised debut o' this thing, me bucko, I had t' make some concessions.

I gave up t' idea o' t' bent contacts for t' original MMX style igniter (at least temporarily) and cut the electrode blanks t' be a bit narrower. I still had some slippage problem with t' press but it was less severe when I used some pliers t' try t' take all o' t' bends out o' t' blank. After a bit, a pair o' serviceable electrodes were cut and affixed t' t' head. A little messin' around showed that I had somethin' that, me bucko, while nay yet perfect, was serviceable and seemed likely t' be better than what I had before.

In t' meantime, t' base and box were undergoin' their final steps. Ahoy! I masked off t' head supports and the fastenin' screws with maskin' tape in preparation for t' final painting. Begad! T' box be then sprayed with 2 coats o' yellow Krylon. Avast! This was a paint that I got in an auto shop and is supposed t' be very hard. It also dried very fast. Begad! Well, shiver me timbers, blow me down! T' next day I gave t' box another 2 coats o' yellow t' improve t' quality o' t' coverage; that gray primer was hard t' cover. Avast, ya bilge rat, me proud beauty! I probably would have given it another coat but I ran out o' paint. Well, blow me down! Blimey! T' base and support seemed t' be done at this point.

I be in t' home stretch now. Avast, me proud beauty! Blimey! Blimey! I cut out a big stack o' electrode blanks and drilled them out. Ahoy! Avast! Blimey! They were then mounted t' t' heads and I had some spares left over just in case. Arrr! Blimey! With that, I had 9 heads ready t' go. I had planned for 10 but one o' them disappeared someplace along t' way. All that was left be t' launch rods and t' fit things together.

T' rods were fabricated from 0.047 music wire. I cut t' 36" pieces in half t' give 18" segments. The rods were bent at a right angle 1.5" from t' bottom givin' that much length t' fit into t' receiver. Aye aye! 1.25" farther along, shiver me timbers, t' rods were bent back t' vertical. This gave a straight shot over t' igniter slot. Things seemed to line up right and I be feelin' pretty pleased with myself. Ahoy! T' rest o' t' rods were then bent into shape.

Lucky for me, shiver me timbers, I had an MMX Vulcan sittin' handy and be able t' put it on and see how things lined up. Aye aye! It did fine!

I be lookin' forward t' tryin' out t' new rack at me next club launch but rain made our field unusable. I used t' sunny day t' try fittin' t' heads t' t' rack and see how it went.

T' first step o' t' mountin' be t' remove t' winguts from t' head mountin' posts. Aye aye! Avast! T' heads were then slid onto t' bolts and secured with t' washers and wingnuts. T' get t' full effect, shiver me timbers, I mounted t' launch rods. Well, blow me down! Each seemed t' have t' proper reach.

T' system was designed so that it could be opened in t' field if needed t' retrieve extra parts. Avast! Blimey! That means it also stores t' rods and heads when I started t' break it down. Ya scallywag! Blimey! It was ready for t' field test.

Finishing:
T' finishin' o' this rack has mostly been covered in t' build but here is a recap.

T' sawhorse base was left its original yellow. Avast, me proud beauty! Avast! Everythin' else was primed. Begad! Ya scallywag! T' box was then sprayed yellow and t' launch heads were painted a dark red.

In time I expect this system t' acquire some labels, additional capabilities and wanted t' leave me options open at this point.

Flight:
I advertised t' availability o' a new MMX rack t' me club and solicited everyone t' bring out their MMX rockets t' give it a try. Aye aye! Ya scallywag! Pretty much as expected though, matey, I be t' only one o' t' Alamo Rocketeers who had any MMX rockets and I only had two with me. Avast, shiver me timbers, me proud beauty! One had never flown before and it was destined t' have its maiden flight coincide with t' maiden launch o' t' new system. Well, blow me down! That would be me MMX Centuri Vulcan.

For an igniter I used t' Quest variety without t' pyrogen. Ya scallywag! Avast, arrr, me proud beauty! I straddled t' leads over t' electrodes and clamped t' igniter in place with a clothespin normally used as a rod standoff. Avast! I tried t' make sure t' igniter itself was at t' right height for t' t' rocket t' set upon.

As I tried t' set t' rocket in place, shiver me timbers, I noticed that t' wooden clothespin holdin' t' igniter in place tended t' slip a lot. Well, blow me down! Then I realized that I could probably do without t' clothes pin and use t' alligator clips t' hold the igniter in place and make contact with t' electrode. T' rocket and t' rack then spent some time service as a static display before it be actually used. When t' time came, though, t' motor ignited instantly and t' rack performed as wished. Avast, shiver me timbers, me proud beauty! T' flight was unstable but I could nay blame that on t' rack.

T' next victim t' be launched on t' new rack was a Fliskits Dead Ringer. Well, blow me down! Begad! Usin' t' clips as before t' secure t' igniter, it was set in place with little or no fuss. Ahoy! When t' launch button was pushed, arrr, this rocket too took t' the air instantly and had a good flight except for t' loss o' t' nose cone. Begad! Begad! Unfortunately, me bucko, that loss precluded any more test flights for t' new rack that day.

Summary:
This rack accomplished most o' what I set out t' do but I already see room for improvements and modifications. I hope t' set it up for a few flights at an upocommin' Freedom launch and then will consider some of those modifications.

This is nay a light system but that mattered less t' me that its durability and ease o' use. Blimey! So far, I am happy in those respects.
