You can do it by hand, your new book will explain I think.

ST,
My godfather, you blokes don't miss a trick. Yes I have "the new book" A Complete Guide to Milling, and every second day, I plough through another section. I have to pop into hospital every second day for a top up and oil change. Reading a book with one hand is a challenge. Trying to open a pack of sandwiches tightly wrapped in cling wrap, is a real challenge.
But that's another story.
Stu, you are just about due for a visitor, I'll PM you first to make arrangements. In about a week.

For things like this the DRO does it so easy without working out all the maths. Some just think of a DRO as a measuring device but with all the added features it's a lot more.

Ken,
Oops, wrong book. The PCD maths is in his Dividing book(number 37). Although there is plenty on dividing heads and indexing heads in the book you have.
I'll start clearing a path the the VSD.
For those Harold Halls books a question. Milling a complete course page 70, Dividing page 65. There is a picture of the bearing block being carefully slit. What's the point of the center piece? Why go to the trouble of two vertical cuts and then two fiddly horizontal cuts. One vertical and one full length horizontal slit would do the same job.

I was watching that rotary table on ebay with the idea of doing a similar conversion - non-standard gearing wouldn't make any difference after the driver was tuned and calibrated.
Once the price started going up, I decided I'd be better off building one myself though.
