I’m sure there are other discussions but these threads might enlighten.
I need to update my frame but I’ve set it up full size but tend to work in a 4 x 3 ft area so i could just buy smaller boards even though i’ve been cutting down large ones. I guess there’s more value for money in the larger sheets.
So the outside sheet tends to stay in place unless i’m working with something that isn’t 18mm thick or need to cut larger. I probably need to think bigger with future projects to start using this to its full potential.
