2x72 inch belt sander

[Radioman]

Hello I’m new here and am amazed by some of the tooling I’ve seen so far! Some very talented people on this site. I thought I’d share a tool that I made recently. This is my 2x72 inch belt sander. The only store bought parts on it are the motor, belt, on off switch and the bearings and axles. I made all the pullies out of 6061 aluminum on my Logan 10 inch lathe. 5° total bevel on each pulley. 2-1/2° on each side of center. This is enough to keep the belt tracking straight. The pulley on the very top is the tracking adjustment. A small turn of the screw is enough to get any belt tracking on center. The belt platten is extended slightly from the frame so you can sand past flush on both sides of the belt. The bed is nice and big for plenty of work support. The frame is made from 2x2x1/4 steel. Plenty strong enough. The motor is a 2hp Grizzly piece. Again plenty of power to spare.

I have some more photos but must have hit my limit as the uploader stoped me from adding more.
