    Post 100 teeth

    I used the setup of change gears as recommended by Paul A. and the rope around the chuck as suggested by Wierd. I hung a small anvil on it to take up the slack in the gear train. It all worked well. It took hours, basically operating the lathe as a hand powered shaper with an acme form tool turned sideways in the tool post. I decided to make a 100 tooth "gear" for future indexing purposes. Although the change gear combo works to produce 100 divisions, it is difficult dealing with the lost motion. I now have a 100 tooth item that I can use directly on the spindle mandrel for indexing, that eliminates having to deal with lost motion. Thanks guys.

    Great, I'm glad it worked. Many other dividions are possible in the same manner with standard change gears. I am working on
    chart. The main values that are absent are the prime numbers that are not represented in those gears and multiples of them. When it's done, I'll see if I can post it somewhere.

    Paul,

    I'll be happy to host it on my server. I think I'm going to have to set up a South Bend specific page, maybe do a little digging through the archives for tidbits. I have the right to post anything of mine and with permission from others will post whatever seems appropriate. This is not something I will be doing right away, summer offers too many other jobs to do. It would be a good project for next fall.
