ok, i got my table very level BUT, the foot-slate is slightly crowned. i have a nice "made in usa" aluminum machined carpenters level and when i rest it on the center of this slate i can spin it. elsewhere this isn't the case, the level doesn't spin because it's flush with the slate. so i know it's not my level. also; it's not the cross member mounting wood because i just sanded it slightly and pulled the slate way off center and it does the same thing in the same spot. so it's slightly crowned.... i'd rather have a valley than a crown because you can shim it up. how should i deal with this? should i just shim the center slate to line up with the high-center crown of the foot-slate?

Take all the slate mounting screws out then check for crowning.
 
that's what i did. i even elevated the slate off of the center support. same thing. it's not too bad but detectable. the level will spin on the high spot and nowhere else and same thing after flipping the level.

thanks!

What do you mean elevated it off the center support?
 
i lifted the slate off off the frame and supported it on both ends with a 2x4 so that i could rule-out the center support pushing up on the slate and causing a "crown".

Did you rule out the frame not being flat, not dipping downward on the outside edge of the timber frame?

thanks for the reply: i think so..., because when i lifted the slate above the frame, the wood i used was very uneven and the slate was slanted. i just wanted to make sure that it wasn't the center support pushing on the slate... exact same outcome and i've moved the slate a few times in different positions. but it's not too bad. i might lightly sand the high spot or not. i haven't decided.
 
If it is only the end slate that is crowned, and you are sure that it isn't the frame member that is causing the crown, you should be able to correct it.

If the center slate is true, you can press down on the crowned end slate when you glue the slates together.

i hadn't thought about that.....i had it ALMOST done but then noticed that it's rolling on on both corners on the head-slate. i'm going to remove all the shims and start anew.

thanks for the help...
