The plans note that JB Weld can be used to fill in cupping caused during bending. Filling the tubes with sand seemed to eliminate any cupping. and also prevented any tendency to kink or collapse the tube. Also, bulkhead E was used instead of bulkhead F (per the plans) to produce a smoother radius.
We are now waiting on the canopies before proceeding.
Plan note:
The canopy bows should not be bent or cut without the canopy on hand. There are several dimensional disrepancies in the plans (surprise!) and the bow patterns are too short. Oh well, always remember - PBER (Prior Building Experience Recommended) - or ohcrap for short!
