W&S Cutter Grinding Gage?

[CPeter]

Somewhere along the way, I acquired this gage. What is it for? Does it have any use in a home shop?

Maybe back clearance for a HSS lathe bit? The 71* side may be for steel and the 64* side for alum? Just a guess.

For W&S turret lathes, Used to assist in grinding the cutter for a single cutter turning tool.

Looks like it is a crude (stamped sheet metal) gauge for grinding tools to those two or three angles. I say possibly three because there appears to be a third angle along the top edge, possibly for negative top rake on a lathe tool.

Is it useful in a home shop? Well, if you need one or more of those three angles, with only marginal accuracy, then by all means, use it. Personally I would toss it in the scrap steel bin and use it when I need a piece of unknown alloy steel about that size. Or is it aluminum?

There are shops that still run and make money with Warner and Swasey turret lathes.
I'd put it up on Fleabay and find a buyer.
It's similar in function to these. https://www.ebay.com/sch/i.html?_fro...te=1&LH_Sold=1
