Spacing for the grinder

[Nameless]

Instead of those tabs, why not use 1.5" long unthreaded spacers from McMaster Carr? Simplify it a big and look much cleaner as well. Just a thought, I'm gonna do that with mine I'll post pictures when it's done

Hi Tim,

Yes spacers can be used. This would save some table time for sure. I priced them out at McMaster-Carr and they got kind of spendy. Also, bare in mind exactly 1.5" spacer is too tight for the 1.5" tool arm, so another 20 thousandth of spacer is required. I ran one strip of 0.020" aluminum right down the middle of the spacers to give that wiggle room needed to get the tool arm in and out. You could add a thin washer to accomplish the same thing.

Let us know how it comes together.

Dan,

I'm curious as to why you chose the individual spacers, plus your aluminum shim, as opposed to a 1/2" (plus a hair for the shim) x 3/8" thick piece that would be tapped on each side?

Thanks,
Dan

Hi Dan,

That would work too. Cosmetically it would be better. The three plates would be 1/2" thick by 1-1/2" wide by 6" long.

I went with the stack of spacers as it uses the same thickness material (3/8") as all the other frame components and saves on 18 holes that need tapping.

How much of a shim do we need for the 1 1/2 bar? I'm guessing about 1/32"?

I used 0.02". 1/32" (0.031") would work fine.
