Howdy! I'm fairly new to the turning vortex, & am learning faster than I can put it all to use. But I've got a problem with using a face plate. Is it necessary to put a spacer, shall we say, on the face plate between the work piece & the steel face plate? Next, & this is driving me crazy. Once I've mounted the work piece to the face plate, it always seems to be off center, or wobbly? I'm making a pair of tumblers. I used a 3/4" roughing gouge to get the spindle to size. I used a skew to smooth things up, & take out the tool marks, & get my actual size. I cut the spindle in half, & centered the first half on the face plate. When I turned on the lathe, my work piece "wobbled" like crazy!! I rechecked the center, & it was ok. What did I do wrong? My lathe is no high end machine. Its a hf 12 x 36. The lowest speed I can run is 1135 rpm. Its a might fast, but I'm learning. Any help would be appreciated. Thanks for your time. Brad.
