[pianotech] Size of Pinblock Drill bit?

[Terry Farrell]

I think this is about the best picture I have of the track system. The rails are nothing but 1.5" X 1.5" X 1/8" steel angle. The wheels are replacement wheels for a sliding glass door from a home improvement store. Very simple and works very well. Both the X and Y direction tracks are designed this way.



While I really love my jig and it works very well, I don't know that it has any advantages over the Nossaman hover drill press jig for drilling pin blocks. If I were to do it again and wasn't drilling plates at all, I'd build the Nossaman hover drill press jig - works at least as well, is much easier to build, less expensive and easier to store. If you are drilling plates for vertical hitch pins, I guess my rig does have some advantage for that.

Takes me a long time and is frustrating.
