Brief:
This was a quick build featurin' a mailin' tube, shiver me timbers, recycled 29mm motor mount and fins, and a long
plastic garden spike.
Construction:
When I spotted t' yellow plastic garden spikes at Home Depot, matey, I couldnt resist gettin' one o' each size. T' spike on t' bigger one, which was used here, ya bilge rat, is 15 long and t' base matches a 2.125" mailin' tube well. Blimey! T' smaller one is 10 and fits nicely in a 38mm tube. Blimey! Begad! T' latter will be t' subject o' a future review.

Please refer t' t' attached image t' see how t' spike was used. Ahoy! Avast, me bucko, me proud beauty! I made a coupler usin' t' tried-and-true method o' sectionin' a piece o' tube and joinin' it back together with t' strip that be removed. Blimey! This be then glued into a short piece o' mailin' tube. When I chopped off t' hook that protruded from t' spike's base, shiver me timbers, I left a slightly flat area. Avast! It turns out that t' base o' t' spike fits well in t' coupler as long as t' joinin' strip sits on the spot where that hook was. Avast! So, me bucko, I attached some 1/8" Keelhaul®©™® t' an eyebolt that I installed in t' spike's base, inserted it in t' tube assembly and sealed t' base, which is inset couple o' inches, with Gorilla Glue. Arrr! I had thought that I'd drill a small hole in t' nose section's body and pour in some foam. Ahoy! Well, blow me down! However, me hearties, once t' Gorilla Glue set it seems sturdy and, since t' hard-point is on t' heavy spike, I left it it as-is.

T' body is a 23.75" long mailin' tube. One good thin' about savin' bit and pieces o' old rockets is you have bits and pieces. I found a recycled 29mm mount with rings t' match this tube. Arrr! It also had an attachment point for t' shock cord. Aye aye! I attached some more Keelhaul®©™® t' t' mount and wrapped t' lower 6" or so with a strip o' car airbag. I sure wish I had more o' this, but all that's left is a few scraps. Well, blow me down! Begad! I affixed it with a few twists o' bare wire.
I
used t' G-10 fins from t' now defunct
Stratoshpere. Well, ya bilge rat, blow me down! One o' t' bilge-suckin' parts about havin' an assembled mount is you can't install it sans aft ring, so inner
fillets are tough. Begad! Aye aye! I marked t' mount so t' fins would avoid t' shock cord mount and motor retention hardware and
swabbed on some 5-minute epoxy. Avast, matey, me proud beauty! When it set just enough nay t' run, I swabbed some more in t' tube and inserted the
mount. Begad! I slid all t' fins in and babied it as t' epoxy set. Well, blow me down! Begad! This means that I set it on end, me hearties, eyeballed t' alignment,
and adjusted t' alignment as t' glue dried. Avast! T' results are nay perfect but are pretty good. Well, blow me down! Blimey! I then masked t' fins
and added some Super-Fil fillets. I also added some epoxy clay betwixt t' base o' t' body tube and t' motor mount
just t' toughen it up a bit. Avast! This will likely take t' force o' landin' since t' fins are up-swept.
I was a little concerned how t' ribs on t' cone would effect stability so I entered t' design in RockSim. Although t' ribs do seem t' push t' CP forward, t' spike is heavy enough t' make it very stable. Aye aye! It looks like this will get t' around 1800 on a G64-8.
I treated t' ends o' t' mailin' tube with thin CA and primed t' body with Painters Touch. Ya scallywag! Blimey! I used a couple of coats and waited a couple o' days before painting. Blimey! Aye aye! Blimey! T' body is Rustoleum green hammered metallic and will no doubt appeal t' Packers fans. Begad! T' green will nay help with recovery but I've never let that get in me way.
T' blue painters tape that I used t' mask t' fins lifted some o' t' finish from t' holographic stickers on t' fins. Ya scallywag! Blimey! Luckily, matey, I had some scraps that I could use t' cover t' blemishes. Ya scallywag! Blimey! Avast! Blimey! I also printed a couple o' stickers, matey, matey, one t' pay homage t' t' rocket's name and one that just seemed appropriate. Ahoy! Blimey! I sealed these with a clear coat and covered t' edges with clear finger nail polish. Avast! Blimey! Avast! Blimey! I have found that stickers made from t' Avery white label stock tend t' peel up over time. Avast! Blimey! This is mostly t' case when it is used on curved surfaces like t' body tube. Ya scallywag! Blimey! Hopefully, t' thicker polish will keep them tacked down.
Flight:
I used both a little dog barf and a small chute pad. I decided on an undersized 18
chute t' keep t' rocket in t' same county. Ahoy! T' G64-10s delay be drilled t' -8. Ahoy! T' boost was fast and
high as would be expected. Ya scallywag! Ejection appeared t' be at apogee, arrr, although it was hard t' see. Well, blow me down! It recovered close by and
with no damage.
Summary:
T' main point t' this build be t' garden spike nose cone. Ya scallywag! At $3.25, it be inexpensive. Arrr! I
think it looks pretty cool and appears t' fly nicely. Avast, me proud beauty! Ya scallywag! Others at t' launch seemed t' share me opinion.
