I use the Hart voicing tool almost every day, and now for the second time the needle has broken off flush with the opening of the tool, and is jammed in there so I can't get the broken shank of the needle out. The last time this happened, I just bought a new tool, but with shipping and everything they ain't cheap. I considered drilling through the hole from the side, but I don't have a bit that small and I'm worried I'd mess up the very very tiny allen threads in the brass. Has anyone had any success dealing with this, or know of how to contact the manufacturer about it?

I ran into the same problem you did Carl.

For the past few years, I've been using a small pin vise that I ordered from a watch repair website. I had to make two modifications to get it working properly:

• Thinned the collar sides so it could fit between the wound tri-chords on Model D's.

• Press-fit a brass extension into the back to make the tool long enough.

What I like about this setup is:

• I can adjust the needle's protrusion from the collet on the fly.

• I can swap in thinner or thicker needles depending on the situation without searching for that tiny allen wrench that I always loose.

I am a fan of the Hart tool and have had to work the broken ends out myself, usually with another needle through the allen screw hole. 

Did you try clamping a vice grip onto the shaft of the tool and sharply tapping the pliers with a hammer to jar the needle out?
