Just bought the JessEm Master Lift Excel and Master Fence from my local Rockler store.
I was on here doing a search for ideas on a router table base for it. Those of you with this top will know what I mean about the crank hardware making it somewhat difficult to design a base. I was about to head off to the lumber yard for some materials.
In any event, I came across some posts from someone who said their JessEm was not dead flat. One guy (Pat Warner I think) noted how a dead flat table is critical for precision work.
Went out to the shop and used my handy dandy, Lee Valley precision straight edge and low and behold, the top has a crown of about 1/8" in the middle running side to side along it's length. It is flat from front to back.
My question is should I return this top or go ahead and design the base and use the weight of the PC 7518 router to help flatten it out, and/or screw the top down very tightly to a flat base and hope for the best? Will this flatten out or should I cut my losses and return it? I hesitate to return it without some real hard thinking as I used 25% off coupons for both it and for the fence (had two coupons), so I got an excellent deal.
Incidentally, I threw the straight edge across the top of my old shop built top and it is dead flat.
Phenolic takes and holds threads really well, so I'm thinking that if I cut some threads in it and screw up into the top from the base below, I can force it down and flatten it out.
I could always return the top, keep the fence, then buy their lift that goes with the 7518, and use my existing router table (based on Norm's) and make a new top that is a bit smaller so it will work with the 32" length limitation on the Master Fence.
Any thoughts or feedback?
Regards,
John
