8 inch bench grinder adjusting tool rest

>Hi,How do you set the tool rest to a given angle, ie 25 degrees.
I tried the Veritas angle setting gauge and I did not get it right.
When I go to use the Veritas MKll honing guide; set up for 25 degrees;
I'm off by a lot. I start to hone on a coarse diamond hone and I'm at it forever; I wore the hone smooth. Your advice and comments would be appreciated.Thanks for your help. Peter in south central nj

a) usually don't bother to use a rest as an accurate setting. I place two fingers on top of the rest and then place the tool on those and find the bevel by feel. It's a technique i learned from a Raffan video on turnning.
b) If you want a generic 25 degree setting, presumably your rest comes with one of those things with parallel sides anb pointy ends. You sellect a side and end set for 25 deg, and jiggle the rest until the plastic end is tangent and centered on the wheel, then you have 25 degrees.
c) What I actually do when I want to use the rest is place the tool I want to sharpen on the rest and adjust it until it is a good fit to the wheel which might take ten seconds or so. If the tool doesn't have the right grind to snug up to the wheel, then after an initial eyeball setting, I turn the wheel on and take a light pass, this should grind a gutter somewhere in the center of the bevel. depending on whether it's centered high or low, I make my final adjustment.

>As was mentioned, diddle with tool rest adjustment until the wheel hits the middle of the bevel of what ever you are going to grind.
I now do all but 1 micron final edge refinement on a bench grinder so I want to hit the correct bevel angle repeatedly. To that end I bought another tool rest for my Wolverine jig and I just leave it set to one place.
I think the Wolverine is the best tool rest out there. It is large(hence stable), robust, steel slides well on the steel surface (unlike aluminium) and best of all it is easy to micro adjust by bonking it with whatever you are ginding (or alternatively something else ).
What I do--long

>I spend alot of time at the grinder and always have to hit a precise angle. I use a wolverine jig along with plywood templates. Angles change as the wheel wears down--I can lose over 1/4" during a long session and everything has to be adjusted. In addition, the angle changes as the wolverine distance changes. My most frequent angle is 30 degrees. I marked it on on scrap plywood. Then I start with a known angle, hold it flat to the edge of the wheel, and then adjust the wolverine to fit. Next I grind a piece of scrap and test it on the plywood (look for light at the top or bottom. Don't forget to wear eye, ear, and breathing safety equipment EVERY TIME you use your grinder. Grinding is nasty and dangerous.
