Hello Jeff.

I had a 36” Brent for years.  The support for the shims was a series of pieces of 2x4 wood and over time they began to
flex, yielding a slab that was thicker in the center than on the edges.  A simple fix was to screw in a length of  1” angle iron
on the side of each wood support and the slabs came out dead even thereafter.   Yes, the shim system is decidedly “old school” but
if you’re not changing thicknesses all the time, it works just fine.
