Routing rabbet for back panel in 3/4" plywood cabinet. Lots of blowout
Question for you guys.
I built 3/4" BB plywood cabinets for end tables and a dresser. I didn't use the table saw or a dado blade to cut the rabbet for the back, as I wanted to just rout it in, and chisel the edges square. I thought that would be the best plan.
I got LOTS of blow out of the top veneer layer though. Thought it might be the bit, but that was not it, brand new bit does it as well. I tried a with the grain cut, tried a climb cut, everything seems to screw up the top veneer layer.
Is it just a bad sheet of ply? Am I doing something wrong? I've never routed a rabbet like this in plywood before, only hardwood, with no issues.
Should I have used a dado blade and just stopped short and finished it off with a chisel?
Should I have used a dado blade on the sides and cut a groove, then slide a back panel in and butt up against the top?
