Progressive blade grinding or whats your angle.

[duffy99]

Sorry for and old bump but how do you blend bevels? I have mainly gators from 80 to 600, On the craftsman metal moves fast? whats the best way for a nice bevel blend. Also what angle should a 4" x 1,5" flat grind bevel be.

Is it possible to do this without a carefully calibrated grinder and blade holding jig? I.e. hand held?

I grind all of my blades in a very similar fashion, but without the use of any jigs. Another difference is that I typically start with a 45 degree bevel (or something relatively shallow) and "roll" back my angles from there until I reach a full flat grind or go as deep as I want to.

I will say that I typically use a tool rest to help stabilze the blade though, and it does help to have a somewhat "calibrated" grinder. I.E., make sure your belts are tracking well and that your tool rest is square with your platen.

All that being said, I would imagine that it'd be a much shorter learning curve to start out with Freds jig than to learn the way I did.

I have Freds jig and I like it allot. The problem I run into with it is I have a hard time keeping the bubble centered at times but I think thats because I am pushing too hard when grinding. How much pressure do you all use when grinding? Do you really hog down on it or take it nice and light?

A convex grind is finished on the slack belt.

Here is a guide that will help you out.

Good luck, Fred

You will get better with practice at keeping the bubble centered. Lock your elbows.
I use a lot of pressure when hogging the initial bevel. Once the bubble is centered I wast no time in making the pass.
