Homemade KMG tooling arm?

[Burchtree]

Has anyone made their own tooling arm for their KMG? I can get a piece of cold-rolled 1.5 square x 20 inch piece of steel for 16 bucks, but would it need any treatment, and how tough would it be to drill and tap the large bolt hole? (just need one for my hollow-grinding wheel).

Thanks -- Burch

I'm using square steel tube. Light and works like a champ.

you remember what size hole you had to drill and tap? I'm at work and will probably stop by Grizzly's to pick up the tap before I go home.

Cold rolled should work just fine. As to the drilling and tapping, just throw it on the mill and be done with it

For the contact wheel spindle it's 1/2-13 UNC, so you'll need a 27/64" drill. Maybe Rob will chime in and tell us the size of the workrest holes. I'm saving up for a KMG so I considered making my own tooling arms, too. Let us know how it turns out!

Sweet -- just picked it up and for 16 bucks, it can't be beat. I hate going from platen to hollow.

I should be beaten from going from flat to hollow.

I agree

Worked like a charm, and only cost me about 30 bucks total --
