Post pics if you like! I've been reading reviews about barrel vises and the issues the reviewer's are having. Some state they don't get enough holding/clamping pressure/force due from either the bushings are slipping, not quit the best fit/contact barrel-bushing or bushing-vise. Some have a 4 bolt and other have a 2 bolt clamping vise. Bushings are either 1 piece with gap or 2 piece. Some use leather for a better hold, lead shims or rosin. Bigger bolt with fine threads are not necessarily going too help hold. 4, 5 or more bolts might not get the job done either. Using a hydraulic press.........well I'm not sure that would/could be a good decision. With several manufacturers having tunnel vision thinking has been a mediocre improvement, if you call it that much. What vises have you tried in the past that were an almost total failure and either used your style of ingenuity to remedy the issue or just returned for a refund?
