Broke a screw off in my headstock! :/

there is an older thread somewhere on exactly that.

 

If you have a drill press and can lock the headstock in place maybe then you'd drill directly in to the screw till it is gone. Basically using a bit smaller or larger. Then put a dowel in the hole with glue and start over.

That is my hack version of fixing it. Wait for a luthier to say what to do.

Good luck and I have done this before but the crews was tall enough to hold onto with pliers or vise grips.

 

If it's too small for an easy-out screw extractor, you can drill a couple of holes right next to the screw and use some small needle nose pliers to rock it out. Then drill the whole mess out with a brad point or forsner bit and make a corresponding plug from maple, or whatever the neck is. If you're meticulous, you should be able to keep the plug at 1/4".

 

I searched a bit but couldn't find the old thread. What you do is buy a small piece of brass tubing that is *just* slightly larger than the diameter of the sheared off screw. carve some teeth in the end of the tubing with a file or a Dremel cutoff wheel. Chuck the tubing in a drill and set the drill in reverse. Basically, place the tubing with the teeth right over the embedded screw shaft and start drilling. The teeth cut down around the screw and when they get far enough in the bit of screw will pull out inside the tubing. The reason you use reverse is that hopefully, the tubing will reach a point where it locks around the screw and unscrews it the rest of the way. This leaves a hole exactly the size of the tubing which can be plugged with dowel and redrilled.
Yes. If a screw is requiring lots of pressure or force to go in, you need to back it out and use a larger drill bit. If you are using the correct screwdriver and are still raising sharp burrs on the top of the screw, same deal.

 

After removing the broken off screw and plugging the hole (as described above), redrill with the correct drill bit and use a little wax on the screws. Any wax, even candle wax helps to lubricate and reduces friction that causes small screws to break. I do this with all my woodworking projects and especially when working with harder woods such as maple. Makes a big difference.

 

^^^ Good advice from pennylink. I use paraffin wax, available in most grocery stores in canning supplies. Use pliers to hold the screw, heat the screw and 'dip' it into the wax block. That puts a thin coat of wax on the threads.



Here's my kit for doing this kind of work - it costs about $15.

I chose a plug cutter to get the same grain orientation as the rest of the surface on the work area.

 

A pic would help.

If a little bit of the screw is still sticking out of the wood you can sometimes grab it with the chuck from a hand drill and back it out (remove the tuner you were installing first)

Exactly! That's the right (and only) way to do it.
