The last couple of projects that I've made were cut out of inexpensive 1/4" plywood from Ace Hardware. The outside layers are clear and have a nice grain, but they are fairly soft. I'm using FD ultra reverse #3 and #5 blades and I'm having quite a bit of chipping along the bottom edge and the top edge of the cut also. My question is, would spraying the plywood with a polyurethane prior to attaching the pattern reduce or eliminate the chipping? Or is there a substrate that might work? I've tried the blue painters tape on this wood and it seemed to pull the wood fibers when i removed it (even when I used mineral spirits). Maybe this wood is just prone to this problem. I'm interested to hear you guys's thoughts.
Thank, Chad
