So the screw hole for my fin screws is a little stripped so that the fin key just turns, any solutions?
I have a solution. Something I've "come up" with is to take an Allen key in the size of a grub screw head and cut it so you have a straight key. Use the straight key as a drill bit and just take it out with a drill. Works well for me.
Not sure exactly what your issue is, stripped screw head or stripped threads in the box, but Gaff's got you if the box needs to be threaded...if you just have a stripped screw in the box that you need to get out and replace, either go to a hardware store and grab an allen wrench one size up to see if you can get that to turn it, or if need be, very carefully, place a dab of a high strength glue on the end of a fin key, place it in the screw you need to get outta there, let it dry, and then proceed as usual.
I've tried the glue on the allen head tip and could never get it to catch. I used a real thin drill bit. Went SLOW and drilled into the screw head. At first it tightened the screw, but then I was able to back it out with the drill. I figured worst case, you could drill it out and re-thread it.
