Bought a used Versatapper awhile back. Like many of them, the upper bearings were rusty and needed replacing. I picked up new bearings and now am having an issue with reassembling the unit. When I took it apart, I wish I had paid closer attention to the orientation of the bearings. NO matter which way I orient the bearings, I cannot get the top cover that holds the bearings and shaft that drives it to bolt down flush. Its almost like something is out of position and holding the cover up a little bit. There are only so many combinations of positions that the bearing can be in and I have tried them all many times. This thing has me frustrated. I am probably missing something stupid. Took a break away from it to write this post. Will have at it again. Anyone have a guess as to what the problem is?
