My last project (New dial for my mini lathe) made me realize that it would be nice to have a rotary table. Purchasing one is out of the question so I started looking through my treasures (junk to anybody else) and came up with a 6 precision cast iron table and base, where this came from I honestly dont remember, but there it is in pristine condition. I also found a 40 to 1 worm gear.
I think I would mount this on a base similar to DeanWs rotary (picture Rotab4).
I have been working out (on Cad) how I would graduate the dial for 40=1 screw and came out with the drawing attached. This dial (I think) will give me degrees and minutes using the vernier along with the small lines on the dial.
My mini lathe will only swing 5 dia. So my approach needs to be well thought out before action. I am not committed to the project yet but I am looking for input suggestions and advice.
