Not having a sharpening jig and finally succumbed to the idea that its easier to use a jig :U
I decided to see if I could knock one up out of a old die cast protractor I had lying around. With its graduated set up it seemed ideal for the purpose.
I removed all the not needed bits and machined up a ali block to carry the pointy bit to swivel on. It has some adjustment for height or length with a simple bolt type clamp. Have yet to try it out but it looks like it'l do the job

Awesome! Metal protractor... never saw one here in the upover. Only one's I've ever seen are little plastic toys.
Good job, Hughie.. looks like it'll do the trick! :)

Yeah, but with an angular result.
That is a great idea , but I don't think I'll be chopping up my good Mitutoyo protractor to make one.

"Combination square," Al. Enco, McMaster-Carr, Grizzly; maybe even Harbor Freight. (Well,no; not them, although the same name is used for a couple other tools.) Starrett, Brown&Sharp, a few other manufacturers.
Neat idea, Hughie. Thanks for sharing.

Thanks, Hughie, and Joe; I've seen them around here, and just didn't know what I was looking at, I guess. Seen 'em in Grizzly's wishbook, too. Duh!!!

We call the sliding T/45degree square we carry on our tool belt a
Combination Square.
