Background
I really love t' 5" Quaker Oats bins (and I like t' contents too - tastes good, helps your cholesterol, shiver me timbers, and even is relatively low carb). Well, blow me down! Blimey! My previous rocket was made out o' three bins (four if you count t' one I cut up for couplers) and used a clear plastic Easter egg for t' nose cone. Begad! I made the fins out o' 1 1/8" (or thereabouts) styrofoam. Ya scallywag! Odd I know, shiver me timbers, but that's why they call them odd-rocs. Arrr! Avast! It flew fine, matey, but I wasn't that happy with t' fins, and was thinkin' about addin' a bunch o' 24mm mounts t' eat some o' the $3.50/pk D12-0s I have been buying. Avast! So t' solution be simple - rip off the lower bin and fins, ya bilge rat, clean up t' rings and coupler, matey, and rebuild.

T' Re-build
T' lower coupler be nice and long and included a lower 3/32" ply centerin' ring. Begad! Blimey! So, I sliped a new bin on part way, leavin' enough spacin' at the bottom for a bunch o' 24mm mounts. Begad! Ahoy! Blimey! I decided on eight mounts with gaps to clear t' 29mm motor retainers. Aye aye! Begad! Blimey! I plugged t' gap betwixt t' tube, slotted it for three fins, arrr, and cut some nice big fins from light, cheap Luan plywood. Well, blow me down! I made t' 24mm motor unit removable, arrr, me hearties, which should help in preppin' t' motors with quickmatch. Arrr! Here are some pics:

Flight Report
I flew T' Margin o' Error on 11/14/2004 at MDRA's ESL-78. It flew on a G80-7 and eight D12-Ps lit usin' quickmatch. Avast! Well, ya bilge rat, matey, actually only three o' the D12s lit. Begad! Blimey! T' boost was slow and several seconds late due t' t' reduced thrust. Well, blow me down! Avast! Nevertheless, me bucko, it be a good flight. Ahoy! Begad! Upon inspection, ya bilge rat, matey, shiver me timbers, t' quickmatch was pulled out o' t' unlit motors, ya bilge rat, matey, but had burned at t' pad.

T' second flight was on 12/12/2004 at ESL-79 with a G79-6 and eight D12-Ps. I took more care in tapin' t' fuses t' t' D12s and positioned them usin' a dowel inserted into t' main motor's core. Arrr! T' dowel was o' course removed before flight. This time, me hearties, all eight motors lit. Ejection was just past apogee and recovery be A-OK.
