How to measure internal spindle thread
Hi Guys,
Someone on Forum , I recall has the same lathe as I do, a 12 x 36 Metal master.
I want to make a spider to fit the outboard end of the spindle which has a 38mm bore.
Pitch gauges are near impossible to read on an internal thread, so I was going to oil the thread and do cast of said threads with some Plasti bond.
Hopefully there's a better way that some kind soul might outline for me.
I have not cut a thread on it yet,so this will be a good exercise.
Thanks
Grahame
