ok, so i am on my second one of these bad boys. i have liked them and have gone through a few things, ie new chains and sprocets, new bases, and dust shrouds, but recently i ust replaced both rollers with ones i got here, and as soon as the were put in, i all of a sudden was getting 1/32" snipe 4 inches in on both sides. yes, the blocks are are installed with the groove /notch face down, and i thought that maybe there was too much pressure on the rollers, so i took it apart and shimmed the table side of the roller hold downs with a small piece of cut flashing as to push the rollers further up and have found now that the snipe has disappeared but the rollers just don't seem to grab as well and i am constantly having to push the stock through. was wondering if there is an adjustment for the cutter head, or does anyone have some newer rollers they can caliper and give me their diameter so as to see if perhaps mine are just a touch too big. or even better yet, maybe someone knows just exactly what the hell is up and can just tell me. thanks.
