A Forgotten treasure in OldCarGuys Toy Shop

[OldCarGuy]

I was looking for a boring head for my Bridgeport. And came across this Chandler-Duplex Boring-Facing head that I had squirrel away. It's been so many years since I purchased it, that I forgot all about it. It has a .750” straight shank and the business end for a .500” diameter tool. Looks in good shape. The rotating dial turns freely; but the head doesn't off set. Looks like another fix-it project...

On my chandler there’s a thumbscrew on the dial. When screwed in it engages the gears that enable the feed. This isn’t mine but, it shows the screw.

I was able to put a #10-32 screw into that hole. With partial disassembly looks as if the end of the screw was broken off in the worm gear. Looks like the screw should have the end turned down.
