Hi- I brain-farted and realized on my way home from work tonight that, while I had planned and built to accommodate kaplow clips for my L2 cert attempt, I had this far neglected to source the parts. I stopped at ace and found one mirror hanger that would work really well, but only one, I need three. Bought it anyway. Also found some smaller ones like those I used on my 38mm L1, so I bought some of those too. Then I found these other things in screen door hardware that looked promising.
The screen door things fit very well, with one concern: the tail rests against the outer edge of the airframe.
I've fiberglassed the tube, so it's not just cardboard, but I'm worried that the rearward force of the casing at ejection will turn those three tabs into levers (fulcrum is the retaining screw) and mash the tube in, releasing the casing.
I could throw a bunch of washers on there so the brunt of the force isn't taken by the tube, but don't know if I'm being paranoid. Any advice in the next few hours is appreciated!! If none comes I'll washer 2 and use the third as a test.
