I'm boring into some hard end grain using a pretty big forstner bit. This
is on a lathe at a pretty low speed. Lot of smoke and heat with the first
1/4 inch, so I thought I'd stop and ask if I should lube the bit. I seem to
recall seeing a demo where the guy used a light brush on of WD-40. The last
thing I want to do is start a fire on the lathe.

Yes, I should be using gouges for hollowing, but I absolutely suck at this
(although I anticipate improvement with practice).

Any thoughts?

Forstner bits have no clearance so they create a lot of heat. Go very slow
and use paraffin wax for lube. Pull it out of the hole frequently to clear
chips and apply more wax.
