tenon machine

I'm looking for a tenon machine.

I'm trying to set up my shop to have tools on mobility bases to move to the timbers. I have some ideas about holding tools plumb to work on badly twisted timbers.

Are there any used tenon machines out there?

what does a tenon machine look like?

A tenon machine has four circular blades that makes both cheek and shoulder cuts simultaneously. The one used my shop is made by Hitachi. From what I understand, the used tool market in Japan is wide open right now. If you were to e-mail me I could check on availabilty. The cost for a new one is about 5K.

Years ago I fellow advertised a tenon cutting set-up that attached to a Woodmizer sawmill frame. This would allow a timber framer to place his timber on the sawmill bed and slide the tenon cutter over the timber and cut a tenon on the either end.
If you owned a sawmill you could buy just the sliding carriage, or if you didn't own one you could buy the hole machine.
Also, I've seen pictures of shops where they set-up two radial arm saws in the same line or plane. One was fixed and the other slide on a track to allow you to move it for different length timbers. Each radial arm saw could be set-up with either a saw blade for cutting off the timber or a dado saw head for hogging out wood forming the sides of tenons.
