Machining Rucker 9” Straight Edge 45 degree, hold down??

Ok, all done with the mill. On to some paint then the surface grinder.
I’m still not sure how I’m going to hold it.

Added some paint. I did find heat affected zones on the top and on the tips of the edges. I think it will be alright.
My face mill wasn't too happy.

I tried to balance simplicity while using large pieces of ferrous material to block in the piece.
It’s pretty rigid but there is movement back to front after several attempts.
Back to the drawing board.
I’m thinking of drilling and tapping some low carbon steel to add ways of clamping the piece while util the magne forces.
Being inexperienced is frustrating at times.

Worked it out.
The top side had some hot spots I had to stone flat si it would cooperate.
The finished product is very nice imho.
Now, to remember how to scrape.

That worked out good. The grinding finish looks great.

Thanks Joe,
I‘m beginning to understand what it takes to get good results. To be honest, I wasn’t so sure my spindle bearings were any good. This new ceramic wheel was almost perfectly balanced right out of the box.
Once I put an initial cleanup dress, (I use pencil marks to verify) it only took .005” or so.
The side to side movement is non existent.
The Sopko wheel hub fits correctly also.
Buy quality grinding wheels, that’s the lesson I got out of it.

This is a video of the last clean up pass before sparking out. Man I love this machine!
