Default Lathe wiring question

I would like to set up my lathe so I can change directions of the turn. Can this be done easily or is it just to complicated to attempt. I am hoping some of you with electronics backgrounds would answer my question. Thank you in advance.

First of all the motor must have "getatable" connections that are intended to allow them to be altered using a suitable switch made for this purpose like the American made one on my metal lathe. This is a job for an electrician.

Hi Chuck,
before you think about reversing the lathe direction think about preventing the chuck from unwinding when the machine is running in reverse. Titting a couple of grub screws is a good idea

Hi Chuck,
Good advice so far. I am not sure why you want to reverse the "normal" direction but I am sure you have a good reason. Being an electrician (retired now), most motors sold these days are not reversible. You will indeed have to have it checked out by a person knowledgeable in this area. If you take the motor off and take it to a motor shop, not a place that just sells motors but one that works on them, they can look at it and tell you if it is even possible to do it with that motor. If they say yes, they might sell you the needed parts and even install the parts for a nominal charge. or give you a wiring diagram you can follow. It wont be cheap for the reversible drum switch if that is what it takes, but taking it to them is a lot cheaper than them coming to you! Not sure what area you are from, but an electrician around here in West Texas is about $125.00 an hour with two hour minimum. Too pricey for me and a plumber is even higher!
Good luck! and remember...

Chuck there aren't very many things that can be done well or safely on a wood lathe with it turning in reverse. I'm curious what you want to do that you feel you need to go the opposite direction.

Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.

Chuck, I turn powder horns for muzzleloaders. I turn them at a very low rpm (usually under 100 rpm). Sometimes they need to be sanded in the opposite direction they were turned. The same with antler and bone.

Ok. Unfortunately the former comments that it may not be possible is highly likely since the manufacturers didn't intend for them to go both ways and probably wouldn't have used a bi-directional motor. You may have to make a homemade setup. What about using a drill press? It will spin your work in opposite directions depending on which end you attach to the quill. Lee Valley sells some supports for sanding drums (used on the bottom end of the drum) to be able to use them on a press. You might be able to use that as your tail stock.

Okay here's my dumb question I'm not lathe operator but I do understand basically how they work why can't you take the project off the lathe and reversed ends would it not turn the opposite direction

Is it a belt driven lathe? You could play around with the drivetrain. I don't know what type of lathe you have, if you could move motor, put a twist in the belts, etc
