Portion of a picture that was posted elsewhere on Lumberjocks, it’s a “lumber curing room”. You can seen green logs stacked all over that have been cored and the only machine in the room capable is the lathe. I assume they align the pith at each end and drill it out. Kind of interesting. Makes me wonder what they are doing with the wood after it dries.

Full picture here:

What kind of bit would you use for that? I’m imagining something like this:

Rick, caption at bottom of the page talks about wooden legs, for artifical limb company. Holes do not look centered can only guess will get more processing and fitted with steel hardware later.

Bill’s right. Prosthetics manufacturing. What about that ceiling? It’s fantastic.

Rick, that cutter you show looks something like it’s a Slug cutter, used in drilling holes in sheet metal where drill bits would be too small. I have a friend who has a whole set, from 3/4” up to 2”. Your picture looks like it’s a deeper “slugger” than what I’ve seen. It’s just a fancier hole saw…........ Jerry (in Tucson)

Tin ceiling tiles made a comeback a few years ago but I bet those originals would go for a pretty penny in architectural salvage. The bit I posted is a hole saw for wood, heavy duty industrial type. I was just curious if anyone knew about coring wood like this or what kind of bit was used.
