[CAUT] Aluminum hammer rail (Screw hole) repair

[Barbara Richmond]

Hi Jim,

I bought the Recoil kit, but it has no screws in it.  What screws did you use?  

John Dewey also mentioned this repair in his class, Action Frame Diagnosis and Repair, so, if it is OK with you, I will also list him on the submission since I am putting together a special "TT&T goes to the convention."

Thanks,

Barbara

  List,

   

  Here's a way to repair stripped screw holes (Especially if an oversized screw strips) in an aluminum rail that takes less than a minute or two. "Helicoils" is what they are called. (See attached pic.) 

   

  You drill out the hole and tap it, then insert the little coil which disappears into the tapped threads, and then you're good to go! Maybe this has been shown on CAUT before, I don't remember seeing it. The new screw is actually a machine screw with fine threads so it takes a few more rotations, but this is way better than anything else I've ever tried. The package shows a bolt, but what actually goes in has a Phillips head and looks like a normal screw.
