Hi all, this is my first post. I recently mounted my mini mill onto a 1/2" thick steel plate thats bolted to an antique cast iron sink pedastal. I wanted to fix the column to the steel plate for added rigidity and these old cummins engine brackets in my parts bin caught my eye. They are cast iron, 10" tall and 1.5" thick at the thinnest area. The base of them curves out to clear the mill base bolt tabs, and they clear the head and coarse wheel for the full travel.

That looks great. I have to think that all of that Cast Iron and steel will add to the rigidity of the setup.

The only modification required to the brackets is on the left side where the column isnt as wide the bracket needs a very small amount ground off the base to clear, and the mills only modification is drilling the bolt holes.

The brackets can be ordered through any mopar part supplier and run about 22 bucks each. I've been dying to share this since I found how they fit like they were made for it.

Great idea. Would you post another picture showing the part number clear? Thanks for finding that out

By doing this modification I assume that you loose the ability to tilt the column, Correct?

Have you tried measuring the difference with an indicator?

I havent had time to do any milling yet but I'll report how it does. Yes, it takes away the tilt feature but I'm almost finished building my rotary tilt mill vice. Ive read that the weak spot in the column from the way it attaches to base is an issue and they sell a kit to attach it solid to the mill base. Another thing is a lot of people fill the column with various compounds to add rigidity, which I'm thinking is accomplished by securing the column to the mill stand as opposed to the mill base.

Locating your work with a tilted column is a nightmare. You pretty much have to use a tooling part installed a a known location, pick it up with a edge finder, and use trig to get the X location based on the tilt angle, the height of the ball's center, and the ball's radius.
