:thumbup: So the bed will be very similar to my old Myford lathe Steve .

Two Square/flat ways :med:

Similar to my Craftsman, too, Rob :) (and that micron tolerance lathe). The Craftsman has another feature I'll be borrowing, but we'll keep people guessing on that one til it's time to make it. Remember, early on I said this was going to be a combination of things I'd learned from both my lathes. :proj: :scratch: :beer:

And similar to the Schaublin 125 - a very fine lathe indeed. (I tried, but failed, to buy one from our toolroom when it closed down.)

Steve,

How are you going to fit the ways to the side rails?

Phil.

I used to think that a lot of things that people did were a waste of time :scratch: but these days I'll send hours making or repairing something that would have been cheaper to buy :loco: and when people ask why my normal reply is "Because I can"

Great work as usual :D can't wait to see this progress :nrocks:

Phil, I'm going to set them upside down on the surface plate, epoxy as a bedding compound, let that kick overnight, and then drill and tap for countrsunk screws. That will keep things from shifting while trying to drill and tap, ensure eveness of the ways, won't depend on the epoxy except as a perfectly fitting bed, prevent the glue pressure from bowing the ways if it was screwed down while the epoxy was wet, prevent misalignment of the screw holes from bowing the ways, and probably a lot of other reasons I could think up.

If screw down in a day, the epoxy won't be absolutely rock hard (full cure takes a month for most epoxies) but will resist deformation at the screw pressure vs contact area not to depress the ways, yet there will be some tension in the screw holding the way to the bed.

At least that's my theory! :lol:
