As I get ready to buy the new lathe, I'm trying to iron out potential problems..

One is that I have 2 Oneway Talon lathes with 1" x 8tpi adapters and the new
lathe will be 1 1/4" x 8 tpi..

OK, I don't have a Oneway, mine is a Woodfast Cobra and when I
upgraded to it from a cheap pole lathe with 1" x 8 to the Cobra's
M30x3.5 ( Cobra was sold in USA with 1 1/4" x 8 tpi.) the dealer
simply replaced the 1" adapter in my Vicmarc chuck with the M30. No
problems. In the unlikely event that I further upgrade to a Stubby I
expect to get a screw-in adaptor to fit.

All the quality chucks I have seen have these adaptors available, this
may be your best way to go. I make my own faceplates, weld a M30
nut on a steel circle, drill holes for screws, true with an angle
grinder. Yours would be 1 1/4 nut instead of M30
