Grinder Tool Rest

[RobinHood]

Spotted this design on Etsy.com using pinch bolts. Here is the link.

I think it would be quite stable, versatile and pretty straight forward to make. You can also buy the parts.

A knockoff of: KMG Articulating Work Rest System for KMG-TX, and other grinders! | Beaumont Metal Works ?

Wow, that thing looks stout!

I don’t know it seems to have a rear pivot point that I would think add to deflection / vibration maybe.

 

[GummyMonster]

There is a lot of spots to tighten.
Maybe if you beefed up the clamping force on each?
Definitely nice looking.

With all those articulations, it makes it very versatile. Seems to be very strong the way it is designed. That is at least 5 or 10 pounds sitting on the rest.

I'm glad you think so... How do you slot those joints?

 

[Dabbler]

bandsaw.

 

[RobinHood]

+1 on the bandsaw.

The material is aluminum. You could probably even use a hacksaw to make the slots.

Groan ... You guy's aren't helping me stay focused on 'gotta do's" instead of "gotta haves" lol.

 

[gerritv]

It's not a good day unless you made a tool. Preferably a tool to make a tool.

I'm guessing slitting saw on the mill would work well

Have you had any success running a slitting saw on your mini-mill? Was a total fail when I tried.

 

[RobinHood]

Was a total fail when I tried.

Can you share what happened, please.

Did the saw blade get pinched? Too much run-out in the arbour? Too high RPM?

 

[Dabbler]

?were there feeding problems( too fast? too slow?) back pressure too much? not enough horsepower?

For the most part I think not rigid enough and not slow enough. The saw wouldn't cut, it just got really hot and dulled.

The saw I was attempting to use was rather course which may not have helped either 3" X 1/32" 30T.

Internet consensus seem to be don't even bother trying on a mini.

 

[RobinHood]

That could do it for sure.

Yes. However it was only 1/2" aluminum. I haven't tried to cut any other metal yet. I went fairly slow and used lots of lube
