It really is an awful unit. It doesn't descend an awful lot which meant it was a bit useless for longer router bits e.g. large flush trim bit with bearing on the top. Surface is not completely flat and too small. I ended up bolting a self-made ply surface to it with proper runners. The motor runs ok but it was a little of centre and slightly angled. As with many people, a cog inside the lift mechanism came loose and fell off which meant having to take the whole thing apart to fix. Also, the lift wheel broke so I replaced it with a metal one. In the end, I took the whole thing apart and reinstalled it in a custom made router table, with a shim to correct the angle problem.
Thanks to the recent sale at WWW I decided to get the Incra router lift and AUK motor offer and am so much happier. A much better unit all round. So much smoother mechanism. Lift descends a long way. Motor is smoother and more powerful.
Really wish I hadn't wasted my money on the Lumberjack piece of tat. Definitely a case of buy cheap, buy twice. Strange thing is I have never scrimped like that before and won't do it again in the future.
