A different way of work holding

Can't get by without a hold-down set, IMO. Especially for irregular shapes. Looks like he should have used a center-cutting end mill.
 
What I was referring to was the use of the steel ball under the clamp. I assume these where from a old bearing. I would think we all have a clamp down set, if we own a Mill that is.

His choice in cutter, well, I ll leave that to the user. I know from doing that same job many times over the yrs, the steel balls do make it much easyer to hold it down.
 
You can also buy loose bearing balls. They are useful for gaging, measuring inside tapers, and a few odd things, but definitely handy.
 
Yeah, he's a very good machinist. I've been subscribed to his youtube channel for a few months. It's fun to watch him getter done. He's another one of those guys that uses lots of common sense, which doesn't seem to be all that common anymore.
 
About all I'd do different is put the wedges/spacers right under where I was going tclue clampng. Otherwise with my luck I'd snug the toe clamp bolt just a little too much and break one of the manifold ears off.

I also subscribe to a couple of other machinist forums where their work is way beyond my capability. However I get good ideas on how to clamp down odd shaped pieces where I wouldn't have a clue how to approach it on my own.

123 abd 456 blocks, coupled with those minerature machinist jacks give you all kinds of ways to support something that seems 'out in the middle of nowhere' on the milling machine table.
 
I noted the ball. I have been using them when I offset the tailstock to turn a taper. I made a set of centers to take balls .

I even make the rear "ball Center" offset.
