Larry, I am betting you don't have a lathe so I am thinking drill a hole and insert a smaller dowel.

Measure once cut twice and it's still to short.

This would have been the week that I'd have finished chewing thru the restraints...
If only new layers hadn't been added....

Across the width, or down the length? Size of the dowel and of the mortise, or the tennon.

Either way, you can cut two 45 degree strips in a 2x4, leaving you with a V groove into which you would clamp the dowel. This would be the basic setup whether you wanted to make a tennon on the end or a mortise in the middle somewhere. How you cut the tennon can vary, from using a Japanese pull saw to using a dado stack. Either way, the V groove and a clamp will stabilize the dowel as you make the cuts.

The simple illustration is the essence. If you're cutting a tennon on the end, let the dowel hang over one edge, put the 2x against your miter gauge and use the TS blade to flatten the tennon, flip the dowel over (measure carefully!) and cut the other side. You'll probably have to do some chisel work to shape from round to square for appearance sake.

If you're cutting a mortise, on a drill press, make sure the cut is made where the 2x supports the dowel.

Clamping could just be a strip of wood across the dowel and a couple of bolts sticking up from the edges of the 2x, through the strip of wood, with butterfly nuts to tighten the wood down. I'm probably use a hardwood for the V piece so it's less likely the wood will split. Pre drill a hole for the bolt and maybe use a fender washer underneath, countersunk a little bit, to spread the force of the tightened bolt across the 2x while keeping the bottom flat. Simple, cheap, make it from scrap.

Try Lee Valley. They have some that work like pencil sharpeners. Google tenon cutters for dowels and you will find them other places for less $$.

I had a simple idea posted a while back. http://www.routerforums.com/general-...tml#post383313

I used this a few times to cut tenons on broomstick ends (like for paper towel holders). Not sure if that's what you're trying to do, Larry.

couple of ways to bore out a dowel end...

V notch the end of a 2x...
install a drill bit the same dia as the dowel in your DP...
slide the V notched 2x up to the bit and clamp the 2x to the table...
change the bit to the desired 2nd bore size...
inset the dowel to be drilled into the V notch and clamp that in place...
the dowel will be auto centered to the bit...
bore the hole...

install a drill bit the same dia as the dowel in your DP...
bore/drill a hole in your 2x near the end... edge drill for longer dowels, face side for shorter dowels..
saw of the end of the 2x cutting through the bored hole leaving 60~70% of the hole...
set the 2x back on the DP w/ the bit you drilled the hole w/ set in the drilled hole and clamp the 2x in place...
change the bit to the desired 2nd bore size...
inset the dowel to be drilled into the open sided hole and clamp that in place...
the dowel will be auto centered to the bit...
bore the hole...

either works w/ a 4x4...
a 4x will give you better stability..

This would have been the week that I'd have finished chewing thru the restraints...
