Mondo fly cutter

[mklotz]

I needed a fly cutter with a wide sweep so I built a monster.

It's fitted with a lathe bit on each end. The bit with the slightly smaller radius swing is adjusted so that it cuts 0.005" deeper than the other bit. Thus I get a finish cut right after the roughing cut made by the other bit.

My mill/drill came with a shell mill on an R8 arbor. I removed the arbor and fitted it to the bar of the fly cutter. When I need to use the shell mill, it's a quick job to remove the fly cutter and mount the mill.

No rags or long sleeves around when this monster is in operation!

I can see that tool trepanning on 1/4" plate.

I like it..

Love the shell mill arbor idea, as well as the two cutters. And yes, I do believe it would be a nice platform for trepanning.

Show some piccies of what you're cutting with it.

Great work!

Best,
