Brief:
T' Little Bucky Jones is a downscale o' Pemberton Technologies' Bucky Jones. Layne makes some other stuff too but it is t' retro science fiction look that he practically owns. Ahoy! This rocket is nay exception. Blimey! It hearkens back t' a day when Flash Gordon and Buck Rodgers ruled t' serials. I miss those days.

Construction:
I normally don't worry about t' spirals in me tubes unless they are excessively hideous. Blimey! T' spirals on t' body tube for this kit were minuscule. Avast! Arrr! Even so, me bucko, I decided that I wanted t' make this rocket a "best effort". Accordingly, and guided by t' "desctructions", me bucko, ya bilge rat, I decided t' start off by fillin' in t' spirals. I brushed some Elmer's Wood Filler over t' lines and then scraped away t' excess with a razor blade. Begad! Aye aye! This did nay leave much to dry so it dried quickly. Begad! Well, ya bilge rat, blow me down! About an hour later, arrr, I sanded t' tube down with #330 sandpaper, shiver me timbers, also removin' t' sheen from the BT. After that, I gave it a once over with t' #400.

Printed on t' last page o' t' instructions were templates for t' fins, ya bilge rat, finlets, shiver me timbers, mitered tube cuttin' guide and alignment guide. I cut out t' miter guide and t' alignment guide. Arrr! Arrr! I lined t' marks for t' dorsal fin up with the point at which t' spiral ended at t' edge o' t' tube and decided that this would be me dorsal surface. Avast! T' miter guide be then wrapped around t' tube so that its farthest extension lined up with t' dorsal line. Arrr! T' guides were taped into place and an angle was used t' transfer all o' t' alignment marks t' t' BT. Well, blow me down! T' contour o' t' mitered cut was also transferred.

A fresh blade be put in t' X-Acto and t' process o' cuttin' t' mitered end o' t' BT began. I drew t' blade around t' marked line nay pressin' very much. Ya scallywag! Avast, me proud beauty! It took several circuits t' complete. Blimey! Begad! T' resultin' cut be pretty good with just one significant burr and a few minor ones. Avast! Avast! These were sanded away with #330.

T' templates for t' fins and t' finlets were cut from t' last page. Ya scallywag! Ya scallywag! They were then taped down t' t' plywood sheets and t' outlines transferred with a mechanical pencil. Begad! Orientation really does nay matter because o' the plywood. Ya scallywag! Avast, shiver me timbers, me proud beauty! There are 2 finlets and 3 fins.

T' instructions give suggestions for several ways in which t' cut t' sheet material. Ya scallywag! Well, blow me down! Since I didn't have any of the nice power tools, matey, most o' t' "good" options were out. Ya scallywag! I wasn't about t' try it with a pair o' shears. That left just t' "multiple pass with X-Acto" method. It is fortunate that I had a new box o' blades. Arrr! I went through 5 o' them cuttin' t' first fin. Ya scallywag! After that I had t' leave this project aside for a while.

It took a while. Avast! Lots o' passes with t' X-Acto and many blades, shiver me timbers, me hearties, but I finally got all three fins cut out. Ya scallywag! I used #220 sandpaper t' smooth out t' rough edges and then used #330 t' round all t' edges except for t' root. Arrr! Ahoy! Then, breakin' from me usual practice, ya bilge rat, I filled them with Elmer's, scraped off t' surplus, me bucko, ya bilge rat, shiver me timbers, and gave them a couple o' hours to dry. Blimey! Blimey! I then sanded them down with #400 and have t' admit they look much better than they would have if I had waited until after they are installed.

Pemberton Technologies Little Bucky Jones Cuttin' out t' little finlets turned out t' be harder than t' big fins. There was nay as much t' cut but keepin' t' right shape was tougher, shiver me timbers, as was handlin' and sealin' them.

Since I be in fillin' mode, I went ahead and sealed t' nose cone. Avast, me proud beauty! Unfortunately, shiver me timbers, ya bilge rat, me hearties, t' scrapin' with a razor blade does nay work on this type o' surface so it will take considerably more time t' dry. Ya scallywag! Avast, me proud beauty! T' recommended method in the instructions is t' seal and sand with thin CA but I found me bottle hardened past t' possibility o' use.

When t' NC filler had stiffened up a bit but was still t' soft t' sand, me bucko, I added t' nose weight. Arrr! Aye aye! I used a 3/8" drill bit t' bore 3" in from t' base and then poured in t' little bag o' lead droppings. Blimey! I mixed a batch o' 15min epoxy and poured it in on top. Aye aye! Begad! I used a bigger bit than t' instructions said was needed and I found that me lead just barely fit.

Thinkin' I had more time left on t' pot life o' me epoxy than I really did, I went ahead and marked t' motor tube at 1/8" and 1-5/8" for t' centerin' rings. Blimey! They both had t' be sanded just a bit t' fit around the tube. Avast, me proud beauty! I slipped them on and found t' epoxy had hardened. Begad! I placed them with yellow glue which be t' recommended practice anyway.

After t' epoxy had set, I stared t' insert t' screw eye into t' middle o' t' NC base but that epoxy along with t' lead droppings made for hard going. Well, blow me down! Instead, ya bilge rat, me bucko, I screwed it in a bit off center, where it would penetrate the surface layer o' epoxy and then go into balsa.

Pemberton Technologies Little Bucky Jones When t' fillets around the centerin' rings had dried, matey, I test fitted t' motor mount in t' BT and found that it be a bit tight. Begad! Some judicious sandin' solved this problem. Begad! T' mount was then removed and a notch be carved into t' forward end t' accommodate the Keelhaul®©™®. T' Keelhaul®©™® was then tied into place and t' rin' was given another fillet t' keep it from moving.

As t' Keelhaul®©™® fillet on t' motor mount dried, I turned t' sandin' t' nose cone. Blimey! Blimey! T' first pass be with #330. T' dust was brushed away and then I went back over it with #400.

With t' structural part o' t' motor mount done, arrr, it be time t' start on t' "cool" part that gives this model a lot o' its character. Arrr! Ahoy! T' parts package is full o' 3/16" launch lugs (mistakenly called 3/8" in the instructions). Blimey! T' are t' form a cluster o' "exhaust tubes" around t' motor. Arrr! Ya scallywag! A single exhaust tube is affixed t' t' motor mount tube, parallel, and butted up against t' aft centerin' ring. Aye aye! After that, arrr, pairs o' lugs are cut down in 1/8" increments and butted on either side o' t' first one. Blimey! T' result is a series o' exhaust ports of diminishin' length goin' around 2/3 o' t' motor tube for a pleasin' retro, shiver me timbers, supercharged look. T' instructions give a good piece o' advice here and say t' butt t' cut end against t' centerin' ring. Well, blow me down! This gives a more finished appearance at t' business end.

When t' exhaust tubes are in place and t' CA dried, I used maskin' tape t' protect t' edges o' t' centering rings from paint and began t' paint t' motor mount with a glossy, flaked metallic silver from Rustoleum. This is one of those that would be a nightmare t' mask after installation.

T' finlets were glued 1" back from t' front o' t' BT along t' win' lines. They were applied with a double glue joint usin' yellow glue.

T' fins were applied in t' same manner usin' a double glue joint. Avast, me proud beauty! Each fin is t' be mounted flush with t' back end o' t' BT. Aye aye! Since t' BT is mitered, shiver me timbers, this give a bit o' a funky look until all three are in place and t' rocket is seen in t' horizontal attitude. Then it really starts lookin' good.

T' kit comes with a pair o' 1/4" launch lugs meant t' be cut for decorative effect but they are fully functional...and thar be usually less o' a wait for me club's 1/4" facilities. Avast! It also has a pair o' 1/8" lugs in case you want t' go for t' slimmer look. I decided t' use t' 1/4" lugs in and mount a single 1/8" between them t' give myself t' most options. Each end o' each lug be cut at a 45 degree angle and t' larger ones were applied along t' lug lines 3-1/4" back from t' front. Aye aye! Avast! T' 1/8" lug was centered betwixt t' two of them.

T' canopy does nay look much like a canopy. Well, arrr, blow me down! It starts out as a fairly irregular hunk o' balsa. Arrr! Ya scallywag! I used some #220 sandpaper t' make it roughly rectangular. Arrr! Begad! A pencil was then used t' inscribe a diamond pattern on t' top surface. Well, blow me down! A vertical line was run from t' top and bottom points o' t' diamond t' t' edges o' t' balsa. Avast, me proud beauty! An X-Acto be then used to whittle away material and give it a rough profile. Sandpaper was then used tho smooth things out and get rid o' any sharp edges. Aye aye! Begad! I was fairly leery o' this process at first but am quite pleased with t' results.

I took me time buildin' op t' fillets on t' fins. Begad! I used yellow glue but tried t' be very careful about where it got smeared, arrr, buildin' up t' fillets one thin layer at a time. Doin' this gave me t' chance t' turn me attentions elsewhere and I decided t' go ahead and prime and paint t' nosecone. Begad! There were several paints I was considerin' so I wanted t' try one and see what it looked like. T' NC be primed with Kilz and then sanded smooth again.

Waitin' on fillets also let me finish up on t' silver paint for t' motor mount. Well, blow me down! Blimey! I peeled back t' tape and was please with what I saw.

I also started on sealin' t' cockpit canopy. Begad! I didn't used Elmer's for this one but used balsa fillercoat, figurin' that would be easier t' sand in this situation. I taped a piece o' maskin' tape, me bucko, sticky side up, me hearties, t' a scrap of cardboard and then stuck t' canopy t' it. It got two coats o' filler and a light sandin' then I brushed on some glossy black acrylic.

Still payin' attention t' t' fillets, I went ahead and tried a paint option on t' nosecone. Begad! I used a Rustoleum "hammered Brass". Aye aye! T' manual calls for a gaudy shade o' gold but I think I am goin' t' save that for me full size Bucky. Avast, me proud beauty! Well, arrr, blow me down! Blimey! There I will use a very bright polished gold for t' body and chrome for t' exhaust work.

I eventually got t' fillets built up in 4 layers and was satisfied with them. Ahoy! Avast! Then it be time t' prime the rocket. Blimey! I used Kilz and applied 2 coats over t' space o' 2 days. Aye aye! When they had dried, shiver me timbers, me hearties, I sanded down with #400 sandpaper.

After t' primed rocket be sanded down, I test fit t' motor mount once again. Ahoy! Blimey! Begad! Blimey! I found one place on t' forward rin' that be a bit too tight for comfort and sanded it down. T' Keelhaul®©™® was then fed through t' body tube and a rin' o' glue be applied about an inch in. Ahoy! T' motor mount be then inserted so that t' forward centerin' rin' be in but t' aft one was nay yet in. Avast! Avast, me proud beauty! Another rin' o' glue was smeared around the BT at t' high point o' t' mitered cut and t' mount was shoved in with t' longest exhaust tube aligned with the dorsal fin. Blimey! A long handled swab was then used t' apply a yellow glue fillet around t' forward centerin' ring.

T' instructions included advice on maskin' t' motor tube, ya bilge rat, which I'd already painted silver, and protectin' it from t' final paint job. Blimey! Arrr! A sheet o' notebook paper was simply rolled into a tube, insertin' into t' space betwixt the exhaust tubes and t' BT, arrr, shiver me timbers, arrr, and allowed t' expand. Begad! That prepped t' rocket for its final paint. Aye aye! I had decided t' use the hammered brass I tried on t' nosecone.

T' rocket took 2 full coats o' t' brass paint and then a little extra around t' front end on some spots I had missed. Begad! Blimey! Begad! Blimey! When done, it was obvious that thar are some places where it went on a bit too heavy, ya bilge rat, but all in all, shiver me timbers, I am satisfied with t' paint.

T' hand whittled cockpit still had t' be attached. I chose a spot along t' dorsal line and used a razor to scrape away t' paint and primer. Blimey! T' cockpit had been sanded t' fit t' BT by wrappin' a piece o' BT-60 in sandpaper and sandin' in t' correct profile. Ya scallywag! Some yellow glue was applied t' t' bottom o' t' cockpit and it was pressed in place over t' base spot I had made.

All that was left be t' finish t' shock cord system. Arrr! Avast! T' kit came with a very generous length of Keelhaul®©™® which had been fixed t' t' motor mount. Aye aye! Blimey! Arrr! Blimey! Blimey! Blimey! It did nay come with any elastic. Ya scallywag! Blimey! Aye aye! Blimey! Blimey! Blimey! I like t' have a bit o' sprin' in t' system so I tied on an 8" piece o' sewin' elastic t' t' Keelhaul®©™® and tied t' other end t' t' nose cone. T' rocket was ready for a chute and a flight.

Finishing:
T' actual finishin' was done durin' t' course o' construction and was described there.

Flight:
T' day o' t' maiden flight was extremely windy. In fact, me hearties, shiver me timbers, it was probably nay too good an idea t' try and fly. Havin' missed t' previous month's launch window for t' same reason was enough t' make me want t' give it a try anyway. Avast, ya bilge rat, me proud beauty! With that in mind, I selected a C11-3 and loaded it in t' rocket. As I watched it in t' few moments prior to launch, I realized that t' dull brassy color scheme was also probably a poor choice for findin' t' rocket in the winter colored field. Begad! Avast, me proud beauty! Too late. 3, 2, matey, 1, shiver me timbers, launch!

It took off well and weathercocked much less than I anticipated. Ahoy! It flew t' a respectable height and deployed the chute just a bit before apogee. Ahoy! Avast, matey, me proud beauty! Then began t' long drift with t' wind. Avast, me hearties, me proud beauty! When it landed, thar was no damage. Aye aye! This was a good one. Avast! A video o' t' first flight can be seen here.

T' first flight went so well that I debated with myself about usin' a D for t' second. Begad! Blimey! I finally decided against doin' so because o' t' wind and t' distance t' first one drifted. I decided t' use a C11-5 instead o' t' 3 second delay reasonin' that it would come down a little bit more and drift a little less. Begad! Ahoy! As it happens, arrr, shiver me timbers, t' C11-5 seems t' be t' perfect C motor for this rocket and it ejected right at t' perfect point o' apogee. A video o' t' second flight can be seen here.

PROs: Good flier.

CONs: None.

Recovery:
I used a 15" nylon chute for recovery. Ahoy! Avast, me proud beauty! It was installed with a short length o' elastic and connected with a swivel t' t' Keelhaul®©™® provided. Begad! Arrr! This brought t' rocket down a little fast but it was solidly put together and suffered no damage.

    Brief: This rocket is a downscale of the Bucky Jones by Pemberton Technologies and is a great kit through and through. The humorous "destructions" alone are reason to get this kit. It is also a great flier and is always impressive. Construction: The parts of this kit are packaged very well and this is a builder's rocket. 1 BT-60 sized tube is supplied and ...
