I have had to remove the gearbox on my Myford 254 lathe and now need to reattach it. The gearbox is an open design, as below, which mates with the lathe bed to create the oil reservoir. The original gasket material from the Myford factory was some thick brown stuff. No idea what, but it worked as it never leaked a drop of oil. What should I replace it with? The hassle of removing it is such that I want to get it right first time.

I think you want some Flexoid jointing material. I've always bought mine at shows, but it appears to be available online here (no connection with the company, just found it with a quick search).

As this gasket possibly affects the line up f the leadscrew I'd mike a bit of the old stuff and make sure you get the same or as near as possible

And while you're "mikeing" the dead material to allow an "X" factor to the compressed thickness to guestimate what the original was.

Oiled Matt finish brown paper (not the shiny stuff) has been the go to for years of gasket material for steam engines, car an bike engines and "Boxes" for decades, yes, old teknowleggy but it works. We're talking muddle ingineerin, not nuclear power plants.
