The Deck. Cutting and fitting the working surface.
The working surface (the deck) is made out of a single heavy piece. Which is good I guess. You don’t want it moving. Cut from 3/4″ particle board. It takes a good bit of saw and jig saw work. If I were to do this again I think I would make this in several pieces. While one piece is probably fine for the 2′ x 2′ and 2′ x 3′ it’s a cumbersome size board for 2′ x 4′. I see no reasons this couldn’t be two or even three sections. Making it out of several parts would also make getting to the underside plumbing easier, which I can see needing to do when I change out the Platens.
This is an easy step. Just layout the pattern and cut away. Makes a bit of saw dust but nothing hard. I did stain this to help seal the particle board. Humidity will eventually get to unsealed particle board and it makes it look more finished.
