Howdy all—-and thanks in advance for your thoughts and suggestions.
I acquired an old Delta lathe (similar in layout to, but not the same as the 930) for relatively cheap. Based on various manuals I’m seeing online, I’m estimating it’s from around the 1930s. It’s got some rust across just about everything, but it runs.
Now, I have never owned or used a lathe before, but I could see it came with a drive center. The center connects directly onto the axle (or more properly termed shaft?); there are two set screws to drive against a flat in the axle. When I took the center off, it took a fair bit of effort, and I could see the flat on the axle was quite chewed up (seems to have been from various set screws over the years).
I drove the center into a pre-drilled hole in my stock (should have used a mallet, and didn’t, oops). Found the center very difficult to fit back onto the axle; I could only get it half-way back on. I’m hoping driving it into the wood didn’t distort the center—-didn’t think I hit it that hard, but I guess it’s a possibility. At this point, though, I managed to do some turning (which is surprisingly fun—-yay!).
The tailstock has a dead center, with the same setup (set screws against a flat). At some point near the end of my turning, I managed to break the pointy tip of the tailstock center; it was probably just weak from rust.
(note: Here’s where my poor terminology probably takes a turn for the worse, given my inexperience here).
A lot of what I see mentioned around are these centers/spindles/etc with a tapered shank (such as MT2). I would ideally like to have something that would accept such a tapered shank on one end, and the other end I could fit over my axle w/flat. I assume such things exist, but I have no idea what they would be called, or where I would look for them… any suggestions?
Any suggestions in general, if that’s not the best approach to take?
