screw-cutting basics

Andy,
The dimension should read 1-1/16 perhaps I posted wrong. This size I have managed to cut using the thread data obtained from Martin Cleeves book.
I take on board your comments regarding conversion to metric and it makes a lot of sense its just a matter of familiarity which improves with every manipulation

Sorry, Terry - I see you wrote 1.1/16. Obvious, now I look at it.

Personally I would make it 1 1\8 x 12 which is Myford thread , you will have to make back plates and other fixtures to mount a chuck at least , the chance of buying anything with a 1 1\16 thread is slim .

As I posted earlier in the thread, ScribD was taken over by Facebook a while back. They have made it harder to download things from ScribD and I (and many others) are looking for a true sharing website to replace this mess. In the meantime, anybody having trouble getting the information from ScribD is welcome to e-mail me (tangent@olympus.net) for copies of the documents still posted on ScribD.
What mind?

Jeff,
firstly may I welcome your comments as subject of your first post on MadModder
The project in question (GHT's versatile dividing head) is as its title suggests adaptable to most tasks asked of it and was I suspect designed to be manufactured on a Myford for use on a Myford, its versatility depends to a great extent upon the various inner spindle additions
The threads concerned however are for the express purpose of retaining the outer spindle within the main body casting so there is no need or reason for modification of the design at this time. The inner spindle add- ons for fitment of chucks etc.I think will ultimately depend upon the machine that the tooling will be ultimately used on.
