Spring washers help with faceplate setups. Things are moveable, but stay put. I have even made my own 'belville' washers.
a useful tip - belleville washers - thanks Charles

Depending on the size of the bore ? . Use a centre in the tailstock to push the Keats against the faceplate with the casting already fixed into the Keats .This should get you to within a couple of thou
If the bore is larger than the centre turn up a button or top hat bit of scrap the smaller dia to fit the bore . Centre drill the large dia for the centre
A bit rough but the way I was shown to quickly get a rough setting . Then clock it in
cheers
The old fashioned method of adjusting some thing on a faceplate was to push and pulled in two directions in the same way as an independent 4 jaw chuck.
This was why I suggested the addition of 'guides' on a faceplate to control what could be called the x and y axis,
Sometimes the time and tested practices become regretfully forgotten.
Your suggestion has just given me another idea. Perhaps some very strong magnets on the faceplate could be used to act as guides for positioning the keats angle plate
I made a start on the faceplates.inspired by photo of tooling in Valery's thread and Normans comment in that thread " ... perhaps made from welded bits if right angled mild steel. "
- a fabricated Keats plate to make
- and a small faceplate or two. Google took me to Harold Hall
I made a start on the faceplates.
cut some 3/4" bar to make the spigots

on the harold hall drawing, the thread is M10.
the lathe has imperial (inch) thread pitches. thought about making it 3/8". remembered the john stevenson 34 tooth gear, that provides very close to metric pitch

to be filed to fit, Norman, or make new?Finally the 'Potts' circular vertical slide with a No2 MT bore and a Myford spindle 'nose ' arrived complete with its 40TPI Acme thread and a nine hole division plate. There were no Tee nuts and I fished out a bag full.
Clears throat-- they will not fit as they are METRIC! Bloody Metric
