I have a Repton RT1 for turning balls and radiuses on a lathe. It works OK albeit not quite as solid as I would like, especially on a 7x10 lathe, but with care it works. Can I do sort of the same thing using this vice http://www.littlemachineshop.com/products/product_view.php?ProductID=2500 if I put a handle on it? In other words, could I make an inexpensive rotary table, hand controlled with a big handle, using a vice with a swivel base? I know I could make a lot of plunge cuts and then do some grinding and sanding, etc., but it would be cooler to just cut a smooth arc. Would the vice/handle thing work with careful, small cuts? Let me guess, if the hold down nut is loosened, it would be way to sloppy? Rotary tables are pretty pricey.
