Having experience as a car and semi mechanic, I was reasonably sure I could do my own press work on my lower unit. I bought an inexpensive adjustable worktable/vise, which so far has held up great. Thanks Menards . So in order to do the driveshaft bearing I wanted something smaller and lighter, so I purchased this press. Works great hasn't broken a sweat. Light enough to pickup and set on worktable or floor. Love it.
