If you want to see the original P&W position-setting system (which, IIRC, was also used by SIP), it starts on page 11 of this reprint.
Moore Special Tool used an entirely different system, based on leadscrews lapped to something like 10 microinch accuracy (again, IIRC):
Thanks, I will read it. I appreciate.

Good.
That is the set that I have (upper right hand corner of page
11), except that my set has only two of the longest rods, not four (though there are the slots for the other two). It is awkward to get to at the moment, so I can't verify what machine it was a set for -- but it came with all the rods wrapped in rust-preservative paper. (I got it at a hamfest perhaps twenty years ago or so.)I still want to set up a V groove for using them in my Clausing lathe. :-) I've used a lathe (a Sheldon, FWIW) which was so fitted.
Thanks for this. I've downloaded it and it is printing as I type.
Enjoy, DoN.
