In the article below called Methods of work, Bill mentions
an 'upcut' router bit. I also saw the term in the current
issue of Workbench magazine. What is the significance of the
term 'upcut' for router bits?

thanks

Bill

This link talks about when to use upspirals and does mention
problems with veneer unless the router is table mounted.

So you are both right I guess. :-)

Veneerial stuff. I love it.

• Upspiral Info from Carbide Specialties

Always lots of cat's to skin and as many ways to trim. I always cut holes in the baffle or anywhere for that mater after the veneer is on the substrate. (always) That my choice because the last thing I want to do is, cut a hole in a panel, and then cut another hole in the panel in the same spot as the last hole! The precious venereal is less apt to chip, flake or cause some other communicable disgrace to your project if the stuff is locked down too. So That the only reason I wouldn't use an upshear cutter on good veneer. Because there is too much time invested at this point to pull of a flake and make repairs.
Even the best glue (urea resin) only glues the surface and it the veneer has enough figure you can lift a flake and still be glued down.

If your routing pockets. deep dodo, rabbits or other furry creatures the upshear cutter pulls the waste out of the kerf like a good Hoover. wait... that's what he said.
