With the dilemma of several damaged screw-arm threads behind me, I’m turning my attention to some stripped out screw holes. In the picture the screw I’m holding is pointing to the hole that it goes into to lock the depth adjuster, which is just above that. It’s more of a machine screw than a wood screw and it’s got an unusual size – approx. 1/4-18. I believe the hole was originally tapped so that the locking screw simply threaded through the wood to lock the depth adjuster.
That hole is almost completely stripped out and it is slightly conical, with the hole getting larger at the outside My question is: is there a good way to repair the hole so that I can use the original thumb-screw to lock the depth adjuster?
In a related issue, the wood screws that attach the screw arm assemblies to the fence are also screwed into holes that are somewhat stripped and I need to tackle those, too.
The info I’ve found on the internet talks about gluing into the hole some toothpicks or matchsticks. I’ve tried that on some scrap, and it might work, but it seems so hokey.
I guess I could also try a larger size thumb-screw, but I’d really like to use the original. Any ideas?

What about gluing plugs or dowels, then drill into the the plugged hole and retapping the threads? I’ve done this with a door in my son’s room and also a picture frame I added legs that were bolted on and made to swivel… Both worked just fine.8 April 2015 at 2:37 am #126328Matt McGraneParticipant
@dborn – Thanks Dan. That’s one of the solutions I’ve been thinking about. I think I’ll practice on some scrap before I work up the nerve to try it on the plough plane.

Just remember, you will have to drill that hole slightly bigger to ensure you have clean wood for good wood on wood bond.
