Doug, I have had this same problem on two separate occasions. I located a Westward screwdriver, part no. SDS730. It has a 1/4" square shaft. I cut off the blade and ground down the sides of the shaft until it was 3/16" square. Because It is square I was able to put a wrench on the shaft for tightening. It worked well.

The pin block is pulling away from the back frame and I received the go ahead for the repair. My problem is the bolts going through the plate into the block and back frame are Thompson bolts ( square recess in head of bolt) and I can't find any supplier in the U.S. with this large of Thompson driver. The plate bolts have a square recess of 3/16" square or roughly 5mm. I wouldn't mind being a set of Thompson drive sockets so I can tighten up a few other things on this piano. Any suggestion for tool suppliers from are Canadian list members? >Thanks >Doug Mahard, Associate ><!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> ><HTML><HEAD> ><META content="text/html; charset=iso-8859-1" http-equiv=Content-Type> ><META content="MSHTML 5.00.2314.1000" name=GENERATOR> ><STYLE></STYLE> ></HEAD> ><BODY bgColor=#ffffff> ><DIV><FONT size=2>Hi list,</FONT></DIV> ><DIV><FONT size=2>A customer of mine has a Heintzman & Co. console, made in >Toronto.
