I am currently building a Data Cut machine, which calls for a 1/2" aluminum tool plate for the table top. It requires holes to be drilled and tapped for fixtures.
I spoke with some other users, and they would rather have a T-slot type table. So I am looking into using the 8020 stuff as a table top. It turns you that the deflection of the 8020 material (specifically the 1545 lying flat) is actually less than aluminum, as long as I can attach them together reliably.
Anyone else look into or use an extruded aluminum top? Pros and cons?
The size of the top is 38x60, and is supported by a frame of 8020 underneath.
thanks!
