Has anyone used this jig for sharpening

Love that board setup. I use something similar, consisting of a single 1x and block in the middle; one end is 30 degrees, the other is 25 as I recall.

From what I’ve learned in turning tools, consistancy is the key. It just seems like this would work for getting a consistant setting every time. One day maybe I’ll get the Mark ll, nice jig but money need be spent elswhere right now.

I’ve used one for years.
Have 3 different set ups, one for each honing guide.
Simple to make and it doesn’t cost an additional $50.

I’ve got a setup like Smitty’s and it works well with an inexpensive Eclipse style jig like the one shown in that link.
