With a little help from a machinist friend I whipped this together tonight.
My friend had some spare stainless tubing that I used for the swiveling handle - I was going to use some spare 1/2" copper pipe. I threw a little caliper grease into the handle bit - just in case I get smokin' with the crank.
It is a lot better than the little knob that didn't clear the top of the saw. And I spent less than $5 on it.
My friend helped with the bending of the threaded rod by supplying an oxy-acetylene torch. If I were to do this again I would have a bucket of water handy to quench the bent metal in while it is still cherry hot to retemper it to hardness.
Still, it works.
