    I bought the L & S from John way back and finished reconditioning it. The times I ran the lathe, I did recall a little bit of seepage from the headstock bearing cover. I've seen this type of...

    I highly doubt there were any SBL beds harden and ground before 1950 in the 9" size if any of the sizes offered. When they started offering H & G bed ways it was an option all the way up into 1960's...

    The shaft appears to be well rusty in the picture. Definitely not exotic material. 4340HT at the worse, I doubt it. Also, you got two different materials touching each other, stainless against...

    To get a induction unit and coil big enough to heat that up, it would take a direct tap from a 480V line pulling over 1000 amps if not more. Pretty much be a direct tap from a 27Kva line to power...
