Ok, so I can finally gloat properly now that I found the camera cable.
A couple months ago I purchased a DP, a Buffalo No. 16. It has a full 6" quill stroke, and a sliding head. That's right, the whole quill assembly slides up and down effortlessly! It is connected by a chain to a counterweight that's in the column. (The last picture shows the head slid down.) It has a 2 hp Dayton motor, and it's the perfect machine for what I need it to do, that is, bore out huge hollow vessels with a 3" diameter forstner bit. But it's also great for down the road when I get into furniture making again.
P.S. The shop is a complete mess cuz I have been busy installing the ceiling joists and lighting.
