Lathe Modifications Catalog

We can make it better, stronger, faster: the $6 million lathe! This page is my catalog of all the lathe modifications I've stumbled across in my web travels. I couldn't begin to tell you how good they are, but they sure make interesting reading! Read through these to get a sense of what's possible. Once you decide on a particular modification, look at all the different ways people have approached it. Many of these modifications are done by multiple folks, and the variations are worth understanding to make your project the best. Be sure to also check the Random Pix page for mods that didn't have a whole article associated with them.
