I tried out my Veritas mini sharpening jig today! This thing is mini !
If you have large hands this may be a problem..... I have arthritis in my right hand and Carpel tunnel in the left so It was a bit of a challenge to set up. Took me awhile to figure out how to adjust it with the bevel angle jig that comes with it! It is almost like you need one more hand to make it happen! The little instruction sheet wasn't very clear.....but I finally got it......... The hard part it it only has 2 contact points to hold the blade ( the bottom platform of the jig and the top clamp which you tighten to lock the blade in place. Very easy to have the chisel not perpendicular with the jig! So I used a small right angle square to make sure.
The first chisel I did was a Henkels 3/8 in Straight chisel. I wanted to change the angle of the bevel from 30 deg to 20 deg, so I started on a course stone! After a few passes I checked it and I could see a new angle forming on the heel of the bevel. It took about 10 minutes to get it to run to the edge of the blade. From there, I cleaned up the roller and blade and put it on an India stone for about 5 minutes, then the same clean up and took it to a hard white Arkansas stone. After that I finished it up on a Poplar wood board coated with white diamond compound!
Super "shaving hair" sharp! The second chisel I worked on was a Dastra 3/16" small short palm chisel it had what I thought was a 20 deg bevel however it was free hand sharpened for years. Setting this up also tricky but I started getting the hang of it based on the first try!
Got it much quicker and even got the blade perpendicular by eye! I put it on the india stone , beacuse I thought my original angle was close, however after 10 passes ...I looked ant it and say only the center of the bevel coming down! I was sharpened in the past to a convex angle! Wend back to a courser stone and just went thru the steps as I did on the first but it went quicker.....Same results ...Very sharp!
All In all It is a bit of a PITA to adjust and lock in the blade but it easy to use and produces excellent results! I'm sure there must be A super expensive device out the similar that would not have the issue of the blade going out of perpendicular with the jig as you tighten the clamp....but for the price I'm very happy! I now can sharpen my short 3" bladed chisels as well as my mini and micro plane blades!
