Apologies if I don’t use all the correct lathe terminology. I’m on a learning curve.
When I built my Sandmaster 3000 I purposely built the drill stand platform in such a way that it could easily double as the drive for a small lathe. Making this project has been in the back of my mind for some time, not because I itch to become a wood turner, but because I want to TRY woodturning. I also see myself turning a few tool handles. I know I could adapt my drill press to the job, but I think I’d have a harder time turning something on its side.
[Below] There are a few places where I diverged from Cosmas’ video. I used the idea of Jack Houweling to make a drive spur from a coupling nut. I threaded it onto a 3/8 inch bolt with the head cut off. A jam nut keeps it secure. [Jack's video on making a similar lathe is here]
The other improvement I made was to add a ‘live center’ to my tail stock. My dead center was boring into the stock while I was cutting it, causing the drive spur to come loose. I took a bearing from a scateboard wheel that salvaged from the roadside for just such a purpose. I ground down the dead center so the bearing would fit over it, leaving the point exposed. Since the bearing edge would stand proud, I epoxied a washer to it using JB Weld. The bearing sits loose on the shaft of the dead point, but sits well under tension. I can remove it if I want to back the center shaft out or replace the bearing.
The center shaft is held secure by a nut that bears against a second coupling nut that runs through the tail stock.
I also added a nice knob/crank on the center shaft.
This last photo shows how the lathe parts self align with the edge of the bench. There are angles fastened that keep the head and tail aligned. The parts get clamped in place as does the tool rest. Not a perfect world, but just about free for a toy/tool to learn on/play with.
