Miniature coil winder

Doc:
Yes it is not a perfect tooth profile you end up with 3 small flats on each side of the tooth profile. That being said the profile is plenty good enough for small model engines unless you are building a very high rpm engine. And you need ultra precision gears. I used this process in several motors now and they work just fine. As for the flats after running for some time they are pretty much gone. Unless you spin the gear at the same time as the hob is cutting it is truly not really a hob cutter.

Doc:
Preparing to cut final gear for build. Set up and let machine create the indexing strip.

Doc:
Ok I setup machine and machined the last gear so the gears are completed. Next I'll start on the side plates and spacer block. The gears went pretty good. I'll have to remember to do my index strips like I did this one sure beats laying them out by hand. If I was still working I could have plotted them out on the plotter but the machine came through for me and did it correctly. Any way here is some clips of the last gear getting machined.

Seems to worked out I was wondering about the mesh because the tape was crooked in places.

Doc:
I think I maybe not to good with the scissors the ends matched up fine when I put it on the indexer. So I'm thinking I cut it a little off. I noticed it when I put it on but the ends lined up so I went forward with it the way it was. Gear looks fine so it didn't effect it to much if at all.
