Background
I really love t' 5" Quaker Oats bins (and I like t' contents too - tastes good, helps your cholesterol, shiver me timbers, me hearties, and even is relatively low carb). Arrr! 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. Well, blow me down! Blimey! I made the fins out o' 1 1/8" (or thereabouts) styrofoam. Arrr! Blimey! Arrr! Blimey! Odd I know, ya bilge rat, but that's why they call them odd-rocs. Blimey! Blimey! Ya scallywag! Blimey! It flew fine, 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. So t' solution was simple - rip off the lower bin and fins, me bucko, me bucko, clean up t' rings and coupler, arrr, and rebuild.

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

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

T' second flight be 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. T' dowel be o' course removed before flight. Ahoy! This time, all eight motors lit. Well, blow me down! Well, blow me down! Ejection was just past apogee and recovery was A-OK.
