Went to look at the "revised" rivettlathe website.....
Had a brief "oh goodie" moment, when I saw the drawing of the tailstock taper shown on the list....... No cigar, though.
Woopsie...... right on the drawing are two notations...... 1) a note of "approx" against the dimension of the small end of the taper. and ..... 2) a note of "to gage" on the taper itself!
Obviously the Rivett folks had a master and floor use gages for their part, and those items have almost certainly been in the Maine landfill for 40+ years, very unlikely to be any help. Unless some Rivett-minded person saved them and kept them slathered with grease all these years.......NOT!
Drat.....
I do have a possible method of getting at the taper, assuming mine is standard and un-worn..... which is probably a total crapshoot. Fill the taper with the low temp "cerro" alloy metal I have, and then make a female gage to fit, probably of the "parallel surface" type, as opposed to a full female taper gage. probably there will be some errors in that, but hopefully it should be close enough to work.
More work for "later".........
