A big wad of clay around the blank will probably stop the ringing....Pete
I sure hope I didn't jinx you when I commented on boo-boos (lack thereof).But I also know that nothing stops you.
Well, step backwards time. I did some more cutting on the gear teeth after lunch, and ran into some problems. Most of the gears I've done till now have been in brass, this is first large one I've done in steel, and with the recesses already done in the sides of the plate, I am getting vibration and ringing in the plate when making the cuts, which is causing the shaft to move very slightly and slowly in the chuck. Big problems when cutting gear teeth! So, time to remake the rim part. I'm thinking I may try and find a large chunk of brass to make it from, given the size of the teeth it should be plenty strong for the model. I do have some 6061 aluminum that is thick enough, could make it from that as well, though soldering on an axle shaft would not work on that, though I could bolt it to a faceplate...Rethink time!
I wonder if this accessory would have stabilized the rim, so you wouldn't of had the vibration: http://sherline.com/product/3702-adjustable-right-angle-tailstock/ I've got one, but haven't had an occasion to use it yet.

I've got that accessory and it works great! I used it when making my gears.But then again, they were only brass. But I found it a big help, and I think it would help for steel too.Kim
There are certain problems that present themselves given the relative size of your project and your equipment. I am ever impressed with your ready solutions.Lookin` good!--Tim
