Due to money constraints I wound up purchasing a Central Electric, Harbor Freight 12 x 36 lathe. Recently after attempting to turn a couple of bowl blanks that were not balanced the banjo worked lose. Yes, The blanks were grossly uncentered. I attempted to turn them down to balance, however the shaking got really bad. Also I was using the slowest speed setting there was. This afternoon once again I mounted a bowl blank, which were cut from a tree. Now the banjo is really loose, so nothing is going to get turned until this problem gets solver. I have looked over the instruction manual and it appears that I will have to take apart the end holding the banjo. Has anyone had this problem? Its a good lathe, and want to fix the problem that I created. Any helpful suggestions will be appreciated.
