Motorized weld positioning table

Yes, bob slack-adjusters are a good source for a worm drive. I have been looking on Craig's list locally for a couple of years but no joy. They are brake adjusters and when they reach their safety limits they are just thrown away. They had no value and were usually tossed in the dumpster. I don't know what has happened but I can't find "free" ones anywhere!

Many thanks for the good ideas and the link!
