Re: wheels on lathe ?
David Walser
This is a common question. You've already received several answers, ranging from "go for it" to "don't do it". I hope this will be a little more complete:
One of the most important things in setting up a lathe is leveling it. Even a heavy cast iron lathe bed will twist if the lathe is not sitting level on the floor. This will cause the tailstock and headstock to be out of alignment. It's also a source of vibration. You might be able to live with these things, depending on what you're turning, but it's far from ideal.
What does this have to do with mounting a lathe on casters? Since most floors are not level, moving a lathe from one location to another will cause it to be out of level. So, when you are moving the lathe from its storage position to its use position, unless you get it into the exactly the same spot every time, the lathe will be out of level. To me, this means if you're going to mount the lathe on casters, you should use "leveling casters". (Search for them on Amazon for some examples.) Leveling casters allow you to roll your equipment around and, when you want to use it, lower pads (lifting the casters off the ground) to level the equipment and make it stationary.
Hope this helps and good luck!
