DIY Wood Lathe

I finally completed my DIY wood lathe! It is long enough to turn a full length table leg and the tailstock is an MT-2 to support a Jacob’s chuck for drilling. The only thing I haven’t done is make drawers for the lathe stand. I’m waiting to use it some more and figure out the most convenient arrangement for my tools and accessories.

I labeled the controller pictures and included the wiring diagram. The treadmill motor controller is interfaced to an Arduino in order to produce the speed signal and monitor the motor for overheating.

Quite a project! Simple concept, but 1000 details for you to sort out and turn it into reality. Nice!

Nice!

I program microcontrollers all day, but don’t do any home electronics projects.

I don’t know exactly. The electronics really weren’t that much but I had a lot of connectors and small parts already. The treadmill motor and controller came from a broken treadmill I paid $25 for. There were bearings, pulleys, shafts and belts but those weren’t very costly. The most costly item was probably plywood. Turning tools, chucks, etc. were things I would have had to buy anyhow.

Me too Ocelot. I think we figured out one time we were neighbors.

The Arduino platform is great for anyone who already knows C/C++. I found a lightweight state machine framework in C++ and used that because I have a lot of safety checks built into the code for faults and to make sure the motor is actually stopped before reversing it.

NIce work Todd.

I had intended to make a gadget to monitor vaccuum in various parts of my DC system, but never did it. I bought the parts, however.

My co-worker made a speedometer for his ski-doo using arduino and GPS chip. Not only speedometer I think but something that will help his daughter find her way back to the boat launch maybe. But I don’t seem to find time for things like that.

Have the thermal limiters ever tripped? How big of an issue is that?

This is extraordinary!! I’m looking forward to see some woodturning projects, besides thsat technical engineering.

Not yet. I’m just using the thermal switch that came with the treadmill motor. I’m not using the flywheel that was on the motor that provided fins for cooling. However, it doesn’t seem to be getting too hot. I have the Arduino RPM limiting the motor to about 2500RPM and the voltage/current monitor doesn’t show tremendous current being drawn.

Thanks! I’ve already turned several small items and some tool handles.

Excellent. I’ve been looking at the possibility of changing the motor on my lathe over to a higher HP treadmill motor with better speed control. It would take me a lot more time to sort our the electronics of it. I can’t imagine building the lathe too. Excellent work.
