I am thinking about making a bunch of closet doors from birch. These will all be quite narrow - 22" wide x 83" tall for the five largest ones, down to 17 wide and 32 tall for the two smallest. My idea is to plane some 5" x 3/4 stuff down to about 1/2", then glue up "planks" that are bit oversize for each door. I know a guy who has a CNC router that I think will go to 22" wide and I'll ask him (or find someone else if his isn't wide enough) to cut "portrait mode" images into each door - doing three on a 22 x 82 face should leave it looking like a rail and stile construct with two cross members but entirely without joints.
So:
1 - anyone know of a reason this won't work? (or things I have to do to make it work but won't think of unless someone warns me)
2- before they go to the CNC guy these pseudo slabs need to be sanded to a high degree of smooth shinyness - 400 at leasst. Birch is good for that, my sanding gear (several palm sanders plus a small Black and Decker belt sander) is not. What tools and/or methods make sense for this job?
