Well, I received my Lie-Nielsen Chisels a short while ago. I had not had the opportunity to get them out of the boxes till recently.
I wanted to do it right, so I sprang for the Veritas Mark II. I had some left over Christmas gift cards so what the heck. I have the original version, but always found getting it perfectly, square and keeping it through the micro bevel was really hard.
My sharpening medium was Norton water stones. I have a 1000/4000, and an 8000 finishing stone Norton lapping stone to flatten.
Out of the box the mark ii has some directions but very limited. Since my LN’s are at a 30 degree angle, I started with the default, configuration which i found confusing because there are two templates that show 30 degree angle. I started with the default, but found that it was very short(length of blade that extended from the jig). Being LN they were pretty dang flat out of the box and mostly polishing on the 8k was all that was required for most of the six I did over the week-end(4 left to go).
Absolutely no issues getting the backs flat, and the primary bevel done. The guide makes it real easy to make sure you are 90 degrees to the jig.
Now comes the issues part. First chisel was perfect, but the microbevel was skewed. In other words the micro bevel on one side was about 1/16 wide but on the opposite side, is was about 1/32 wide.
First thought was I let the chisel get out of square. checked and no not the issue. Backed off worked back through the primary bevel and did it a second time making sure it was square. Same problem.
Now I’m ticked. How can this be happening since it works through the primary bevel but screws up on the micro bevel. Could the roller be off?
I checked some online vids and blogs and found something interesting. Some were commenting on that if both sides of the pressure bar are not equal it can cause a slight lifting effect on one side causing the issue.
I checked and sure enough, it was tight, but one side seemed to be lower than the other and that would put more pressure on the one side of the chisel. I redid the whole thing being careful to keep them the same(left and right knobs) so that on the top of the chisel, equal pressure is applied across the whole chisel body.
I reran the chisel, and it appeared the problem was fixed. I have to say the chisel was extremely sharp, and a cross grain test, had a feather thin shaving off the end of a board (using the paring handle)
Moved on to the next one, and the problem came back. Now I know it’s got to be my technique. I went to youtube and watched some videos of the mark ii, and retried with a better technique, and it got much better.
By the time I got down to the 1/2” chisel, I had the technique down, and they were coming out perfect.
So final thoughts great tool, but you have to get use to it, and know the challenges based on the design issues. It will handle all from the smallest chisel, to the wide plane blades, but it will take a tad of getting use to it.
I can recommend it. I plan on doing a youtube video speaking to all the challenges and solutions i used so next time someone searches having the same issue, hopefully they won’t waste as much elbow grease and Norton stone grit as I did.
