Doug, wedges wont work. I'm cutting boards down to 5mm thick (about 5/16ths") Also the router sled has to move over the entire workpiece.
I'm laying the pieces flat, and gluing the edges of the pieces to the base board for routing. It works really well. But when I remove the piece, its only 5mm thick, but all the edges have glue on them.
Its a nuisance picking it all off with my fingernails, rather than a serious issue, I just wondered if anybody had found an easy way.
Phillip, the edges are just too thin for ironing. Dont want to use any heat as that will spread the glue to the flat surfaces.
