Fine tuning tooth set.

I use the same method as Mike Wentzloff, but instead of paper I apply a layer of painters masking tape to both inside surfaces of a smooth jawed Machinist Vise. The remaining set can be altered by using more than 1 layer of masking tape.

Wowza. Paper is cheap - that vise ISN'T. :shock:

Magnificent!

Hi Bugbear. Expensive, but IMO having a quality machinist vice where both jaws meet perfectly in parallel plane is essential for this task.

A couple of lengths of thick O1 steel in a metalworking vice would do the same job, and cost a lot less.

Further down in the replies Mike W explains that you could use a normal metal vice and add cover jaws that meet parallel - I'm going to do this to fix my fairly rough casted vice faces by using 4 bits of metal from worn jack saws; 2 inner sleeves next to the jaws and 2 outers that will be the parallel faces and put some car body epoxy resin in between the layers then clamp the jaws till the inners meet and a bit extra, even if the faces are not co-planar to the jaws they will be parallel to each other which is all that's needed.

Evening out the set on both sides of the saw plate can be addressed by using a number of different methods. But this alone will not give you a guarantee that every tooth point has a common height. And this leads us to why I firmly believe tooth set should be applied prior too final sharpening.

*The best way to insure that every tooth point has a common height is by lightly jointing the top of the teeth.*

#Shaping of the saw teeth has been completed (slight flat remains on every tooth point):next;

*Set every tooth with the pistol tool;
*Fine tune the set
*Dykem;
*Light jointing across the top of the teeth (stop when every tooth is touched);
*Dykem;
*Complete final sharpening of the saw teeth.*
*Test and evaluate the saws performance.
