I have watched lots of videos on YouTube of large diameter fly cutters and they mostly seem to be disks. Is this solely for rigidity?
I was considering mounting a 13" long piece of 2" wide by 1" tall piece of aluminum on one of my spare shell mill arbors and punching a hole at 4", 5", and 6" from the center to hold a 1/2" boring bar with two set screws per hole to hold the boring bar sticking out the bottom.
I figure that leaving the bar long will help with balance. I'd cut the boring bar short because length isn't useful. Shorter the better.
I'm sure aluminum might not be ideal but it doesn't swing as much weight and I'll rarely use it. It would be easy to balance with the boring bar in the middle hole and end up pretty well balanced.
I've turned down a job dusting off the top of a tractor head because I couldn't clean it all up in one pass. I'd like to be able to max out at 12".
