Machining a square question

[niget2002]

Set up the round bar in your mill vise so it's sticking out of the side. Use the side of the end mill and mill the front and back of the round bar instead of the top and bottom. No need to flip it. Then you have two parallel sides.

Two parallel sides is enough for an open ended wrench.

If you really want all 4 sides for the full square, then mill the top while it's still clamped. Flip the bar over and use a dial indicator to index the front until it's vertical. Then mill the 4th side.

Thanks all, as usual the Journal has come to the rescue with several ideas that will work for this novice machinist.

And yes, I will be watching any tire wrangler very closely. These ceramic rotors are about $2500 each.

You have failed the test! You were supposed to indignantly state that NO ONE else was touching your car other than you, and that YOU would be taking the wheels in to get tires!
You can use a hex bolt screwed into the threaded end of the guide stud to act as an indexer for 6 flats while machining the other end to the size you want.

Will the case be bespoke?

Mahogany with brass trim

Plus rich Corinthian leather for a lining...

Why don't you just use a wheel jack and save yourself the hassle?
I do and never as much have nicked the caliper or rotor.

Winner, winner. I have a plain jane 19 Stingray. I just got new autocross tires mounted on my extra set of wheels. I take them to Discount Tire in the back of the Pilot. Even my car, I have no interest in some neophyte tire changer driving it, figuring out how to lift it, or pulling and reinstalling the wheels.
