METALWORK FORUMYeah, yeah, I know these are supposed to be Woodwork Forums, but many woodworkers also do a lot of metal work. Here is a forum for those who dare to work in metal. Use it wisely.

No, it's not for cutting up flies, it's for scimming metal up to say 50mm wide.
This was also designed to screw straight onto my Unimat 3 mill spindle, so again, the rear end was drilled and tapped M14x1 to suit.
Make any changes to thread size, to suit your mini mill.
Made of 30mm brt ms x 40mm long, it consists of only three parts, the body, and three M6x10 grub screws, couldn't be simpler. Just add your cutting tool, up to 8mm sq. shank.
Clamping is via two grub screws, and a jacking screw is positioned inside the slot to adjust the angle of the cutting tool.
To be honest, I have not had a lot of success with this cutter, I don't think my mini mill is strong enough, or I have got something else wrong.
Attached are a couple of pictures, and a pdf drawing. Coming up next is a set of parallel clamps, and a scissor action knurling tool, and there's more after that, so stay tuned, the best is yet to come.
Hey Ken, mind if I post your Fly Cutter project to my website, ProjectsInMetal.com?
I'm compiling projects suitable for people just starting out in machining, and I think this is a good project for beginner to intermediate skill levels.
