My Worksharp 3000 offers preset angles 30/25/20 and I'm reasonably confident that the angles are spot-on. Trouble is that over time a lot of my chisels have lost all semblance of the correct angle having been hand sharpened on a diamond stone. In fact, inadvertently creating many an RB (a bevel of a certain distinction ).
I would have used the Worksharp but, as you may know, trying to get replacement discs was nigh on impossible and in my true fashion I bodged things for as long as I could. So I decided to sort things out once and for all and came to the conclusion that the starting point was the ability to quickly restore the 30 degree basic angle.
So I bought a cheapie Axminster grinder. This one...
and naively thought that if I fixed a small block of wood at the right angle then I'd rest the chisel on that and away I'd go. Bit like this
I wish I knew why my photos are not behaving as they used to.
I put a chisel in the Worksharp to grind the makings of a reference angle and then stuck the wooden block down on the grinder rest and repeated the trial grind. You could immediately see that the two angles were way out. A moments thought suggests that the line of the grinder rest is not on a radius but offset. The rest is not adjustable anglewise. My reference has to be the Worksharp since all finer grades will be done on that so my question is this...
...is there an easy way to get the grind angle on the grinder the same as the Worksharp?
