Down And Dirty Bench Grinder Build!

[seagiant]

Hi,
Picked up a FB Buy, Craftsman Block Grinder for $25...

Decided to make a Lathe Tool Sharpening Station for my Machine and Wood Lathe tools.

Rebuilt the Grinder with new Bearings, and then made some Rests from Scrap Steel I had, not in the best shape but usable.

Nothing fancy but works great and I can set the exact angle I want now.

Have a Green Wheel for Carbide and an AO Wheel for HSS..

Worth the effort and should of been done sooner!

Very nice!

How did you make the slots in the tool rests and get them parallel to the motor shaft axis?

That's almost identical to the only grinding table I ever made (I made just one and switched it side-to-side as needed. Mine was basically training wheels. The angle fixture was the first thing to go, then the table itself. I grind by eye/hand now.

Hi,
I squared the Grinder base to the Trac that the Rests run on.

I drilled holes to make slots and then went to my BP Mill...

Hi,
Yes, some operations the angle slide is not needed or even in the way but easily removed.

I see no downside to this and even more Rest Tables could be made to widen the use of the Grinder.

No, there's no downside at all. I just found, after a lot of use, that I didn't need it. It sort of trained me on the angles (in a general sense, I'm not pretending that I hold a perfect 10* (for example) when I'm grinding - but I hold close enough. My incentive was probably in part because I had to move my table to use the other wheel. Being lazy, that meant that eventually I was roughing out on the table (course wheel) and finishing freehand (on the finer wheel). Ultimately I found that I could do either without the table and that eliminated a few steps, strictly as a convenience. There's no quality difference in the cutters, and if I looked in my cutter drawer I would be hard pressed to tell you which ones I ground with the table, and which I ground without.

Hi,
I have always free hand ground myself but wanted to try by the book to get the correct angles and see the difference.

Here is a Vid I found and this Guy made an interesting Gauge to get or check angles on Lathe Tool bits.

Nice looking and WELL built! I suck at grinding tools and I probably won't get any better!
