I’ve always admired the pretty aluminum bases some of us are using. But since my XL is mounted to a 6” MDF torsion box I don’t need the stiffness such plates provide. So I’ve been living with variations of MDF wasteboard for the last three years.
MDF is still my go to for most projects. But I thought it’d be nice to have nice, flat, shiny surface for the more dimension critical projects I’m now contemplating.
So I picked up a chunk of 12x24x0.5” 6061 Econo plate from McMaster Carr for $86.
Surfaced both sides using a 3/4” mini indexible mini mill from Busch Machinetool. Then broke out the trusty Fesstool 400 sander and went crazy.
Came out pretty flat. Surprisingly flat actually. Not bad for a woodworker anyway.
The the larger holes are 0.3” in diameter, cut on 2” centers to match the pattern in the MDF board below. On the rare occasion I use bolts for hold downs I’ll bolt thru the shiny piece to the board below.
The bolts to hold the plate down are also on the same pattern, enabling the location to be flexible.
