Altmill Base: Plywood vs MDF

Hey mrf,

I didn’t want to barge in this thread for the origional question was this or that and what I have is a third option that I thought would not add to the discussion, but on the other hand, my solution might help mitigate your warping problem.

It’s not fancy, nor estatic, but it gets the job done and it’s the most cost effective way I could think of to have a “spoil board“ level to my machine despite a warping slab of mdf being the base of tne machine.

Small pine strips, that can be leveled individual, saving time on surfacing.

Here’s a topic on these for more info.
