Fly Cutter with R8 arbor for the mill..Plans available by Rossbotics.

Thanks Doug, this is a great one!
I wanted to make this one when I first put eyes on it. This works out to be the best fly cutter
I have. Two others in my quiver are either too big or too light for my mini mill. Anyhow you can
get the prints from HMT via this link:

I used hot rolled steel that I had on hand. It was 1 3/8" in diameter so just a bit smaller
than the 1.5" speced. Followed the plans and this one is now my best fly cutter.

Cheers, JR

That came out nice JR. it does leave a nice finish and you can run it at a pretty high RPM ! I did find another use for it other than just a fly cutter, it did a great job on creating a grip pattern on the new vise jaws I made for my bench vise too.

Thanks for posting your completed project. click the photo to enlarge

Thanks Doug, I never would have thought of using the fly cutter for that pattern.
If you had not posted how it was done I would have thought hours were expended
with a rotary table and end mill! Your method would be so fast in comparison.

Just goes to show us that age old ideas have their place. And it's nigh near impossible To match the finish you achieve with a fly cutter with anything else. Plus the tooling is way less expensive.

Thank You mwmkravchenko, it was an interesting tool to make. The overall speed
is quite good when surfacing with one.

Nice fly cutter there. I can see where having a set of these in various diameters would be nice. I have to believe that this is a better balanced solution than some fly cutter designs.

Nice work! When you post a tool you made from homemadetools.net plans, you get another set of plans of your choice for free. Let me know which ones you want and I'll get them sent over to you.

Thanks Jon, I think I would like to try Rossbotic's nice tool post grinder. Might take me a while to build that one.

Nice build JR...man the finish with that is spectacular! Looks like you nailed the grind and speeds on that. Also a mighty fine finish on that hot roll and the keyway on the R8!

Great to see and hear how much of a value Doug's designs are and the versatility of scales/adaptability.

Hat Tip and a Nod, JR!
