Thread: Grinder accesories and ideas

Here is a few pics of the full hollow I went a little too far. The difference between success and failure was leaving enough material to hand sand. Mind you this a 3rd attempt at full hollow this thin. The next razor should be a success but we will see.

There is still some layout dye that I didn’t thoroughly cleaned off. I may just leave it as is and clean up the tang and spine some then just shave with it to check my heat treat for edge retention. I always learn more from my mistakes.

How do you do the jumping? Looks nice and clean.

A checkering file. I use a file guide to get it started, once the first set of tracks is established you can move on down, registering on your file in the already established cuts. I think the size is 00 which is 20 lines per inch, iirc.

I have my sights on a 9" 1° conical disk grinding surface now.

9" beveled disc


Hard to see, but here is the disc installed on my 2x72.

What is the purpose of the conical wheel?

It is used the same as a flat disc, but the bevel gives you clearance on the other side of the center.

I'm in the process of putting a flat disc on the other side of the wheel.

I'm doing this mainly for two reasons, I can have two different grits mounted, and having discs on both sides makes them effectively turning in opposite directions (picture grinding a flat grind knife edge up on either side).

A third but less important reason is that I figured I may as well make this second disc flat to help evaluate the difference between flat and beveled and see if there are uses where flat is better. I can easily bevel it in the future if I need or want to.

The 9" dual sanding disk/wheel rocks for general shop work. I have three different grits turning at the same time.
