I just received my new JessEm mast-r-lift yesterday and must say I’m pretty impressed with the quality and function. I did run in to a bit of a problem though. The leveling screws that thread into the top plate to level it with the table surface are REALLY tight and hard to screw in. There are 10 screws and I probably spent 30 minutes getting them in as much as I could. They kept feeling like they were crossthreaded, but they weren’t, so I’d back them out and try again, but kept having the same problem. Eventually I managed to get things pretty much level except for the left side of the plate where it really matters. I ran a few test pieces and they manage to just slightly get caught up on the table where the plate feels like it’s a few thousandths of an inch too low.

I ended up using a 3/8” drive ratchet with a hex key attachment to tighten the screws, and broke the tip off, so I’m afraid I’ll damage the lift if I try to tighten that screw any more.

Just wondering if anyone’s had similar problems or if I got a lemon. My rout-r-plate that the lift is replacing didn’t have any problems with the leveling screws. I sent JessEm an e-mail yesterday and haven’t heard back yet, so I think I’ll give them a call this afternoon. I figured I’d see if anyone else has had a similar problem or has any suggestions I can try before I call them later.

Greetings Vritgo,

The question I have for you is….. did you pre-drill the holes for the leveling screws before you tried them? Most levelers are pretty tight, but you MUST pre-drill, sepecially if you’re going in MDF, just thought I’d ask…

Rick, I’m not sure I understand what you’re getting at re: pre-drilling. The screws I’m talking about thread down through the top of the router plate and protrude out the bottom of it where it rests on the MDF ledge that supports the plate. Those holes are all pre-drilled and threaded from the factory.

Ok…..I withdraw the question…..sorry… lol. I was thinking you were coming up from the bottom under the cabinet, through the MDF, and leveling the plate that way….I’m not familiar with the Jess-um master-lift, so my presumption was wrong…..I just had it pictured in my head that was what it was…..Now I got ‘cha…I’m glad you explained that…I’d of been screwed up all day…......When I said pre-drilled, I meant through the MDF up to the plate…...That’s a first for me….Learn something new all the time, but I’m old-school…...lol.
