Default Glue and Bits?

Do they mix or should they be kept apart?

Is a glued up pice of material going to be any harder on a bit than just plain (no glue) material going through the bit?

Hi Noddy

Yes, the glue will gull on the bit,,,build up..and it will heat the bit up...

They do make bit cleaner that will remove it and the pitch...it's very hard on bearing as-well ,like lam.trim bits...

Some of the Epoxy glues will nail bits in heart beat...

Yes. Remove the glue. Never fun to a bit get ruined.

So, what about the case where I take a bunch of strips of 1" X 1" material, glue them up (say for example a multi wood cutting board) and the want to use my router to round over the outside edges, and cut a 'juice groove' around the inside perimeter of the wood?

If this just one of those cases where it can't be avoided, so you route with care, clean your bit after you are done, etc.

Glue it up. Rout it.

I've routed tons of MDF (which is basically all glue...) without too much dulling of a router bit. I doubt routing a few passes over a laminated block is going to damage anything.

If you're really worried about ruining a 'good bit', wait until Woodcraft has one of their $5 router bit specials and pick up a round over and a core box bit that you won't be afraid to dull.

If your talking about a glued up panel then unless your routing down the glue line then I think the exposure to the bit is very minimal. I think you will be fine.

We don't avoid stretches of rough road to minimise tyre (tire) wear, the same goes for router cutters and the various materials that we use them on. Don't forget that any cutter that doesn't need to be a critical size can be sharpened by the same people who sharpen saws, so it pays to buy quality cutters that justify the cost of sharpening compared to replacement cost.
