Brief:
Scratch 4" V-2. Arrr! Aye aye! Flies on H through J 38mm motors. Ya scallywag! T' nose has interchangeable weights so t' rocket can be properly weighted for any given motor. I use a silk 36" chute I got from AEROCON.

Construction:

• 1- 4" dia LOC body tube 8.5" long. Glassed with 6oz cloth and 30 min epoxy. Aye aye! This rocket has no payload section but one can be added inside the nose cone. Begad! Ahoy!
• LOC 4" NC for t' nose
• 4" PML NC for t' boat tail, which is cut t' 11.5" exposed length. Ahoy!
• 4 fins made from 3/16" 4 ply plywood, ya bilge rat, also glassed with 6oz.
• 1- 3/16" 54mm centerin' ring,
• 2- 3/16" 4" centerin' rings. Aye aye! Blimey! Begad! Blimey!
• All rings have a 38mm hole and are birch plywood.
• 14" 38mm LOC motor mount. Ya scallywag! Begad!
• 3/8" strap Keelhaul®©™® for shock cord. Begad! 2 pieces o' this form t' harness that mounts t' 2- 1/4" by 3/4" u-bolts, matey, which are located on t' top CR o' t' MMT. Avast! Ya scallywag! There is 20' o' Keelhaul®©™® from thar t' t' nose cone, which mounts in a similar fashion t' 2- u-bolts mounted on a bulkhead inside o' t' nose cone. Arrr! Begad!

Nose Cone:
This be t' most complex area o' t' rocket. Well, blow me down! I cut t' shoulder off o' t' LOC NC t' 2.5". I sanded t' tip o' t' NC flat and drilled a 1/4" hole in t' tip. Ahoy! I took 15.5" o' stainless steel 1/4" allthread and ran that through t' hole. Before that I used a small 1/4" washer and 1/4" nut and secured that about 2" from t' tip o' t' allthread. Then inserted t' allthread from t' shoulder side o' t' NC through t' hole in t' tip. Begad! That gave me 1" exposed through t' tip. Arrr! I used another 1/4" washer and nut and secured t' allthread tight at t' tip. Ya scallywag! Then took some 1/4" fender washers which are about 1.3" dia and slipped them down t' allthread from t' shoulder side. Well, blow me down! I got some round/flat lead fishing weights in various weights rangin' from 3 t' 5 oz, arrr, drilled 1/4" holes through t' center, me bucko, slip those down t' t' big washers, arrr, put another big washer on top o' t' weights and then used a 1/2" stainless steel tube about 8" long t' push down on t' weights. Ya scallywag! I used a bulk head with t' same fender washers on each side, put that over t' tube and secured t' bulk head with a 1" section o' 1/4" coupler. All metal parts are stainless steel. Ya scallywag! Arrr! There are two u-bolts on t' bulk head for recovery harness attachment. Well, blow me down! Avast!

I can change t' rockets weight in under a minute. Ahoy! T' only problem was the allthread stickin' out o' t' tip o' t' NC. Begad! Avast! I be goin' t' fake it out with glass and epoxy, me bucko, but since I had cut t' tip off t' PML NC for t' boat tail, I had a perfect tip t' put over t' allthread. Blimey! I took an extra piece of allthread, arrr, put a nut on it and heated it up with a torch. Aye aye! Ahoy! Then took t' tip of the PML NC and sunk it into t' HOT nut that was on t' allthread. Avast! This worked out better than I had hoped. Avast! Well, blow me down! I now had a tip that I can screw onto the allthread, me bucko, ya bilge rat, arrr, and I finished it off with sand paper t' make a perfect fit.
