Yeah for disk grinders

[itrade]

Disk grinders aren't for just little blades are they?

I'm working on six 9" x 2" kitchen choppers (Japanese Santoku) - that's a huge flatgrind area. I used up a 60 grit belt on one blade and had a few deep spots. So I tried working them out on an 8" disk.

Wow baby is that sweet. Using a magnet to help hold on I was able to create a perfectly flat surface on each side using 100 grit. With the swirling grind lines it is easy to see where the low spots were and remove the 80 grit marks.

Now I will go back with 220 grit on the belt grinder. With this level of flatness and swirl marks, I imagine it won't take long to clean up and we're ready for heat treat.

For those of us that spend a lot of time flatting out the initial bevels this is a great time saver and produces excellent results.

Just passing information on.

I love the 6" disc on the combo grinder. I can get the profile of the blade perfect with that and the table. I was also able to cut a beautiful swedge on the bowie I'm working on.

When I taper tangs, I start on the belt grinder, but finish on my 9" discs. The belt just doesn't get them flat enough for me.

I spoke to Mike on the phone about using the disc grinder for tangs
I never really tried my 9 inch disc,I followed Mike's advice and I am getting very flat tapered tangs,Have a drum switch on mine really
makes it a very important piease of shop equipment.
Mike thanks for the good input.
