Routing plywood (post #106011)


If I were just going to rout a couple channels in plywood I would not post the question. However, I plan to do quite a bit of rabbeting on plywood edges and I concerned that the glue in in plywood might cause excessive ware on the router bits. Has anyone ever routed a bunch of plywood. Could the type glue in plywood put excessive ware on the bit?

Don't sweat such petty details cypress. The plywood manufacturer knows that we'll be cutting and routing they're plywood. Nothing will happen besides normal wear and tear depending on the quality of your router bits. Trust me.

In my experience, any american-made plywood I've routed into doesn't challenge the bits much. But if you are routing imported Baltic Birch plywood, expect some uneven wear on your bit edges. The endgrain is the culprit, not the glue between layers.

When I've got straight edges to rabbit, I prefer removing as much of the cut as possible with the table saw. If you've got dado blades for your saw, even better. Then I follow with a single light pass of the router, never challenging the motor or the bit, but resulting in perfect joints most of the time.

Router bits are generally well engineered and so cheap nowadays that I consider them as consumables. Use them, charge them to the job, and toss them if they're worn out, or send them to the saw doctor if there's some life left in them. I have some that I've owned and used for twenty years, and others that merely pass through that hit the bottom of the 'round file' after just one or two uses or project. Slainte, RJ.
