You know there has been Tennon Cutters that go on drills around  for many many years. It's kinda wild to see people that own a few Tenon Cutters switching to the Logman X .  Some of the reasons there switching to the Logmanx  is,   Wow !!  Have you seen the price for just 1 Tenon Cutter lately!!   I want to put tenons on bigger Logs. !! I want to add a bent log arch to a headboard of a bed. !!    Something we heard just today was I bought a tenon cutter 2 years ago & I hurt my wrist. He said I haven't used it since!! Well all can say is Tenon Cutters That go on drills arn't for everyone!!!  you know there is a reason why you have to have a big heavy duty vise to hold logs. If logs spin loose in a vise your in trouble .
