Pegged Tenon?

I've done many searches online and here for techniques for a Pegged Tenon joint, but unfortunately it all leads me other places. If I search for pictures it shows exactly what I'm trying to do, but I am having no luck finding what its really called or how exactly to go about doing it.

I've had this table in the works for months and this is the ONE joint holding me back. Any help?

Additionally I think I went about it wrong. I tried to practice in some pine, used a upspiral cut bit in my plunge router for a start and then a straight bit for the main work making the hole, followed by a chisel. Well the straight bit didn't do nearly what I thought and I cant freehand a straight line to save my life. The chisel just tore out the wood instead of shaving it off.

I wil help but not sure we are usig the same terminology as far as what a pegged tenon is.I se the mortise in he pic and the taperd tenon thru it and then a dowel or peg behind the joint.If you could give a better explanation I will help.
Chisel and pine are hard.The chisel needs to be very sharp.You would be better off sticking with the spiral upcut bit and a template if I understand what your trying to do.

In simple terms, you cut a mortise in a tenon for a tenon to fit. In other words, for the peg in the tenon, all need to do is cut a mortise however you cut the other mortises

I would use a drill press in place of a router and clean out the waste with a chisel .If I were to use a router and upcut bit I would make a template for the mortise.Stilll has to be cleaned up with a chisel and would be easier with the drill press for me.

Also, look up "draw bore joinery", it is a similar style of joinery but has a minor difference that will make the joint much stronger.

Nice table mate. Theres several ways to cut a tenon, depending what tools you have at your disposal. A router or drill press are the two most common, that ive seen at any rate.

http://www.finewoodworking.com/how-t...ge-router.aspx
http://woodgears.ca/mortise/drillpress.html

Those links explain the methods pretty well. Good luck

You must mean "mortise"

The name of the joint is a "through tusk tenon with wedge".

What exactly is it that you do not know how to do?

Cut the extended tenon?

Cut the hole through the tenon?

Cut the wedge shaped peg?

Cut the mortise in the table legs?

Apologies George, i should have been more specific. I am uncertain how to cut the hole in the walnut stretcher sticking through in order to fit the peg i want to use correctly. The only joint i have left is this one

you have two choices for the wedge....

You can put a single wedge in vertically, OR in this case, I'd use 2 smaller wedges horizontally.

As to how to create the mortise/square holes...
You can drill a series of smaller than needed holes in a straight line and then chisel out the waste to get a rectangular hole. A hollow chisel mortiser would be the best machine to use, but you don't have one. A router can be used to remove all the material except in the corners, where you'd need to chisel out for the
wedge. Keep in mind that the mortice should have a taper to match your wedge.

A wood rasp will clean up a roughed out square hole as good as anything and put the necessary taper in it.

A close look at the tenon coming through the leg, not the tusk. Does in fact show a "peg" in it. Which to me would be because the tenon could very well fail by splitting from the pressure of the tusk. Better peg the tail of the tenon. :)

If the tenon has a tapered side on the "wedge" side of the tusk it won't fail unless the tusk is tapered on the top and bottom horizontal sides also...NOT.
You only want to "wedge" the tenon out, not apart.

AND you don't need a lot of wedge/taper, only a few degrees will do. The tusk should only have a taper on one side the side that's pulling the tenon out.


I hope I made this clear....
