Title: Sharpening an Ulu?
Post by: John ~ LolliPop Farm on September 04, 2022, 10:45:46 PM
Got a job in that had befuddled me as to how to jig this up, any ideas vs freehand?

Hmmm. Tricky. I'm assuming the blade is not detachable from the handle? And that the tape and towel in the photo is hiding the handle?
I think it is a freehand sharpening job.
Or you could use a WSKO with blade grinding attachment, very carefully?

Also, from the photo, it looks like a convex primary bevel with a secondary bevel. Even if you could get a jig on it to enable using a Tormek you would have to be careful to only work on the bevel at the very edge, if that makes sense?

Wouldn't the axe jig work?

Good call.  It just might.

I tried it (https://forum.tormek.com/index.php?topic=3896.msg26438#msg26438)... with some modifications, you probably could, but I couldn't figure one out at the time.

Sissor jig base with a block the width of the blade to top of handle [ shim ]. Ax jig same way
