Jay,

Thanks for your reply.

I've seen this style tenon cutters ...

...used by craftsman, making cowboy furniture and other rustic designs.

Ken I'm very familiar with these also as I cut several hundred double tennons in pine logs for a log cabin deck railings that went all around the house.  I have also made some of the log furniture before using these.  These are the modern version of the ones used by wheel wrights to cut spokes for wagon and buggy wheels.  The Amish buggy makers still use them today.    I can a test to it that it is tiring work if you do more that a dozen at a time.

Yep, one gets a good workout using those tools.
