Default Bit For Edge Jointing

Looking for the best bit for edge jointing on the router table.. Figuring a up spiral 1/2 Whiteside would do the trick but not sure if a compression bit would be better?

Thanks for any advice!

Welcome to the forum Terry. The up spiral might do a bit better but pricey compared to straight bits with or without a shear angle. I would try a straight bit first with a large diameter, for example 1.5". I think the larger diameter will help with a better cut.

Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.

Default Thanks...

Thanks for the help..

So if reading this correctly it seems more or less the opinion is that a large diameter straight bit probably does a good enough job not to warrant the price costs for the spiral cutter..

Sounds good to me to try for awhile .. I will post my results once I get running the bit and glue up some panels..

Thanks for the warm welcome

Over the years I've come across two very different theories on this. One says that you want a perfectly smooth edge on both pieces to be mated and the other says you don't want it real smooth to get a better/stronger glue joint. I went with the latter theory because it was quicker and easer. I run the pieces through the table saw with the fence just a HAIR off of being parallel to the blade. I make the edge banding a little wider than the piece it is being glued to which means the glue up doesn't have to be as precise. I then use my router to trim the edge band flush with the mating piece. I have edge bands that have been on for 20+ years with no problems and in cases where the pieces are of the same wood with the grain running in the same manner you can't see the joint.

Forgive me saying this, Buck, but if you've already run the material through the table saw then all it takes is a couple of passes with a sharp, finely set jointer plane (something lIke a Stanley #7) to get a really good jointed edge. That's a lot less work than any router table set-up in my experience. Sometimes the simple solutions work best

BTW you're right about wanting a smooth edge - roughened edges are impossible to correctly check for hollow joints and never seem to make a tight joint

I think it depends on what your goal is. Extra strength or invisible glue line. Either way will produce a solid glue joint. More surface area (rougher edges) will be stronger but smooth will still be plenty strong. The glue line of the smoother joint will be less noticeable.

By the way, I've heard an argument against rough that goes something like the rough edges have broken wood grain which doesn't contribute to strength. My gut feeling is either approach is good enough.
