Haven't built mine yet. But, how about putting same thickness sheets to right and left of work peice. Maybe a little tape at the end points to make a full sheet with equal pressure across the entire roller?

I use scrap lumber at ends of boards to keep my planer from dishing out the ends of a good but short board.

Just a newbee who hasn't unpacked my PhlatPrinter yet.

 

I buy packages of 3 or 4 inch wide balsa and then glue them together to get the wider widths.

Be sure to put some wax paper on the work table to keep the glue from sticking to the work surface.

If you are in a hurry, use the super glues. If you are in no hurry, wood glue works well. I usually spread a bit on my finger and just wipe the edge of the balsa and set it on the wax paper and butt the next piece up to it and lay some weight on them to help keep them in place.

 

That's pretty sweet. I'm anxious to know what it will cost...

I'm glad the Mark I will still be available to newbies like me -- that's a great marketing strategy.

One thing -- I really wish the Mark II (or the Mark I) would cut a full sized sheet of Depron (27" x 39") -- that would make it easier for me to load the foam... As it is, I will have to cut the full sized sheets into half-sheets.

 

Never mind.
I thought I had an idea, but it must have been gas.
