CONSTRUCTION:

The instructions are clear and easy t' follow. Ya scallywag! Begad! After a series o' warnings about the flammability and t' need for adequate ventilation t' steps necessary t' make igniters follow. Well, blow me down! T' steps outline makin' igniters for Black Powder motors like Apogee, Estes and Quest. Avast, me proud beauty! Then addition steps t' make igniters for Composite motors. There are some suggested wire sizes t' use for various sizes of motors.

Unique Rocketry suppled some AWG 22 solid zip wire t' get me started. Avast! Blimey! I made 11 igniters from this wire, matey, all about t' same length as North Coast's igniters.

T' process is easy. Strip t' wire and line up t' bare ends with a even gap o' ~0.008 and 0.015". Begad! Well, blow me down! T' instructions suggest usin' a spark plug gapper or feeler gauge. Blimey! I used a feeler gauge on a few and then used me eye.

Once stripped, t' wires are dipped into t' Conductive Primer until they are covered completely with t' black primer. Avast! After this you should measure the resistance. T' instructions say that betwixt 1.5 and 10 ohms is normal for a properly dipped wire. Ahoy! Most o' t' eleven I dipped came in at 4 - 5 ohms. Avast! The others measured at 8 - 9 ohms and two were > 25 ohms. I re-dipped those and they came down t' 4 - 5 ohms.

After t' ohm check you are supposed t' dip them in t' sealer. Well, blow me down! I did this and let them dry over-night (only need 20 minutes). When I got up, me bucko, me hearties, I re-measured t' resistance and all t' ones that came in betwixt 4 - 5 ohms were now betwixt 2 - 3 ohms and t' rest were also lower. I don't know if this is expected, but it happened.

T' next step is mixing t' Oxidizer with t' Pyrogen. This makes a very grainy and heavy mixture. I mixed it with a small flat screwdriver. T' instructions are very clear in sayin' that shakin' is nay enough. Ya scallywag! Blimey! This is especially true after t' mix has set for a while. I would suggest makin' 10+ igniters at a time since you loose some o' t' mixture on your stirrin' device.

Once mixed, I began dippin' me igniters. I stirred this mixture every few dips. Blimey! Blimey! Re-measured t' resistance per the instructions. Ya scallywag! Blimey! None seemed t' change. Well, blow me down! Blimey! After lettin' t' Pyrogen dip dry for 1 hour, me hearties, I dipped them in t' sealer. Avast, me proud beauty! Blimey! Voila' . Avast! Blimey! Begad! Blimey! . Begad! Blimey! . Aye aye! Blimey! Begad! Blimey! igniters ala Nick.

T' finished igniter tips were wider and longer than NCR's and that concerned me. Blimey! T' smallest nozzle throat I could pass any o' me new dipped igniters through be a F39. Arrr! Blimey! This be a concern t' me.

I purchased some 24 gauge 4-strand telephone wire and used it t' make me next 10 igniters. Similar results all around. Arrr! Arrr! I also purchased some 30 gauge insulated wire wrap wire from Radio Shack. I twisted t' pairs together usin' a drill as described in t' instructions. I made 8 o' this size igniter and now had successfully dipped some that would easily slid into a D9 nozzle throat.

Overall, for CONSTRUCTION I would rate this kit 4.5 points. Blimey! Although I have nothin' t' compare it to, I found t' Pyrogen mix t' be t' most challengin' part. Well, blow me down! T' obtain a perfect 5 rating, I don't want t' have t' stir it. Avast, me hearties, me proud beauty! However, me hearties, don't let this deter you. Begad! Just recognize that this is a required step and take your time.

When usin' twisted pairs o' wire, me hearties, make sure of two things; 1) they are is at least 5 turns per inch and 2) that you strip both ends before dipping. Well, blow me down! If you try t' strip t' launcher end after dippin' the igniter it may be disturbed enough t' loss good contact. I had this happen after t' primer dip.

FLIGHT/RECOVERY:

The instructions indicate that a 12V system is required. Well, blow me down! I use t' Estes Command Controller with two 7.2V batteries for a 14.4V system. Well, blow me down! I tested one o' the igniters on a garage floor. Ya scallywag! Upon ignition thar was a large flame ball and flash. Begad! Then a visible and audible cracklin' o' t' remainin' igniter head that lasted for less than 2 seconds.

I have used 10 o' these igniters on various 29mm and 24mm reloads. They have all fired t' motor on first pop. Blimey! Avast! I never had a puff, matey, puff, me bucko, ya bilge rat, puff, arrr, me hearties, whoosh ignition either. All were, arrr, 3...2...1...whoosh! The best display o' t' igniters happen when usin' t' 30 gauge in me three 24-mm cluster THOY Snipe rocket. Well, blow me down! Avast, me proud beauty! I successfully ignited all three E18's!

For recovery . Aye aye! . Ahoy! . Avast, me proud beauty! Avast! yes, matey, thar be a recovery mode. For recovery, me bucko, t' wires can be reused. Ya scallywag! Avast, me bucko, me proud beauty! Simply snip t' end, strip t' end and dip t' end where t' previous igniter tip was. Aye aye! Avast! This be nay possible on t' 30 gauge igniters as they crumbled and curled from t' motor exhaust.

For FLIGHT/RECOVERY, I would rate this kit 5 points. Arrr! Ya scallywag! Haven't had a single failure. Can't be better than that.

I asked Unique Rocketry about thinnin' the mixtures and here be t' response: "Yes, me hearties, t' pyrogen can be thinned with acetone t' suit t' motor application. Ya scallywag! Avast, me proud beauty! It can also be thickened by allowin' some o' t' acetone t' evaporate. Ahoy! T' solvent used in all three bottles is acetone. Avast, me proud beauty! T' same is true o' t' Conductive Primer. After several igniter dippin' sessions, matey, users will have t' add a bit o' acetone t' the IgniterMan Pyrogen and Conductive Primer t' maintain t' consistency. Ya scallywag! Arrr! I have a couple o' users who make igniters for their Apogee motors. Ahoy! Avast, me proud beauty! They say they have t' thin t' Primer and Pyrogen in order for t' igniters t' easily fit into the slots o' t' Apogee motor grains."

Overall, t' IgniterMan kit is a win with me. Avast! For t' $30 I have made about 30 igniters. That has already brought t' price down lower than most purchasable igniters. However, t' important fact is that I barely started usin' t' mixtures. Aye aye! Begad! Unique Rocketry says I can get 500 igniters out o' this mix. Avast, me proud beauty! I probably can't with me dippin' technique, but I'm sure I can get 200. Well, blow me down! Doin' so would drive t' cost per igniter down t' $0.15 note including t' wire. Ahoy! This is outstanding! I give t' kit an OVERALL ratin' o' 5 points.

UPDATE 4/00 - A couple o' tips for sucessful clustering.

1) Make certain t' date o' motor manufacture is identical for all four motors. Arrr! Ahoy! At t' very least, arrr, make certain t' two opposin' motors have the same date o' manufacture. Avast! Ya scallywag! Doin' this eliminates t' motor aging variable. Ahoy! Aye aye! Also it's highly doubtful t' formulation changed at any time durin' that day.

2) Match t' physical size o' t' heatin' element formed by the Conductive Primer Dip. Arrr! Also, match t' DC resistance o' t' finished igniter t' with in 0.5 ohms. Avast, me proud beauty! Blimey! This will minimize any igniter ignition skew.

3) Make certain t' use a battery which can supply ALOT o' current WITHOUT havin' its output voltage collapse. Begad! A sealed lead-acid gel cell, motorcycle battery, arrr, matey, me bucko, or car battery works great. Aye aye! You want t' be able to dump lots o' power into that little thermal head so it heats up VERY fast.

Followin' these three steps will help insure all motors fire and come up to pressure at t' same time. Ahoy! Steps 1 and 3 should be followed regardless o' t' brand o' igniter used. - Robert Briody (Unique Rocketry)
