Topic tags/keywords: router lift router table porter cable 7518 jessem mastr-lift-ii question router

Just built a new router table and having some issues.

1. The Porter Cable motor, which is the default motor for the Mast-Lift-II, won’t fit in the carriage. I’ve loosened the tensioning cap screw all the way, and the motor still won’t fit. I even loosened all of the clamping blocks to give it the best chance of sliding in, but no luck. Anybody with this configuration have any tips?

2. i also purchased the overpriced MDF template for routing the insert opening. I follow the instructions in detail and ended up with a 1/2” lip on which to rest the insert. The insert fits great, but the 4 screw holes (presumably to screw the insert down to the table top after adjusting the leveling screws) are partially over the negative space created by routed out table. So it can’t be screwed down. But does it need to be? The instructions don’t mention screwing the top down. With the weight of the insert, the motor and with the snugger bars tightened up, do I need to screw this thing down?

Thanks!!

I assume you have the manual? There should also be some videos. Did you make sure the clamping blocks are properly configured? The 7518 is usually the default set up.

I don’t recall screwing the router plate into the table. That defeats the use of leveling screws.

- EarlS

My Mast-R-Lift II has two mounting holes at opposite corners of the plate. I see on their web site that it now uses screws at all four corners.

Earl, they lock down the plate. You level it with the grub screws, then tighten the four corner screws to lock it down. When I first got mine, I figured the weight would be enough, but as it turned out, without locking it down snug, those grub screws could move due to vibration. Also, the force of doing a heavy cut like a door stile can tip the lift in the mount if it’s not held down.

So, inexile, that is a problem. Those screws need to thread into the top. Also, that motor will fit. Follow Earl’s advice and go back through the manual. The motor clamps are set differently for different motors.

I would not rely upon a lift being in it’s “default” setup.

Verify the motor clamp blocks are in the correct positions for your router motor, per the manual.

You will have to fashion corner blocks to fasten the router lift to the table. I would not rely upon gravity to hold it in place. If there is enough room to easily drop the lift into the table or pull it out, there is room for the lift to slide around and ruin a setup, and any joints cut with it.

I have the Incra version of the same lift, and it is an outstanding lift.
