I made one for the cabinet shop, you never have to push hard on the material, it eats wood, Im usually working near the center of the disk to control the rate of removal.

That is good to know Greg, I think I may even have a reversing switch somewhere that I can add to the circuit. I was going to take a vote as to which way it should run- I guess 'both ways' will win.

I've seen radii milled like that, but never tried it myself. It seems like the part would want raise up off the pin.

Perhaps I should have taken a close-up photo of the radius setup Tom. The pivot was a bolt with a nyloc nut on the other end (underneath) to avoid the endmill flutes lifting the workpiece up. I was a bit nervous of the whole setup but thought it was worth it as a learning exercise. I made sure I was holding the bar in a direction such that a 'grab' would pull it out of my hand rather than fling it into my chest. Started with the endmill just touching the corners, then fed it in .020 for each swing. It was easier than expected, on the second end I took .040 cuts without any difficulty. The limiting factor was the bar hitting the column, this prevented it coming off cut at the start of the last two passes. I contemplated some kind of setup to do the same thing at the other end- with the slot- but figured I'd be playing with fire, especially as that would have been with short lengths. I bolted the two pieces together so I could radius the other end on the belt sander, following the milled radius of the other piece. That went ok too.
