Now that I have filed the edges on two blades 1/4" thick, I am not in the mood to do that again. I am looking at the Kalamazoo 2 x 48 belt sander with out motor, I have one sitting around. This is what is in my budget at the moment and was wondering if anybody had any experience with this machine. The 2 x 72 would be nicer, but a little out of reach at the moment. Thanks for your time.
