Anyone have any good tips on how to SECURELY attach rail buttons (1010 type) to an existing rocket design - in particular one where you have no access to internal portion of rocket (i.e. fin can)
For new designs, i always use a wood block or some other backing piece with 1/4-20 threaded inserts which are solid as a rocket.
However, i'm wary to simply "epoxy" some rail buttons on the rocket, especially since it will be seeing warp-9 loads. (Rocket has previously flown many times on Warp-9 loads using 3/8" lugs up to I1299s, but I hate lugs, especially when it comes to rod whip)
One idea I had was to simply drill a 1/4" hole in the airframe and cut out a small space in the fin can foam, then inject some Aeropoxy into that space and attach the rail button with a screw embedded in the aeropoxy. Or something similar.
Any help appreciated!
Thanks
Dan
