Brian, I believe it was Jim, he did sound like this was a step that was already done at the factory and was suprised I was doing it, directions that come with the unit tell me to check it, so I did.
They also don't mention a front to back measurement doesn't have to be perfect, I'll know better in the future.
I probably would have been better to just fire it up and see what happened, but the impression the directions gave me, is all adjustable points need to be checked before running, and I've thought that of all the machines I've bought in the past.
Lou, its not the rollers, its the main frame that the cutter and rollers sit in, it has a machined surface at the front edge of each side and you true this edge to the bottom bed.
With enough space to remove the chain easily, this would have been maybe a hour to do and no big deal, I spent over four hours trying to get the unit adjusted, partly because you really need two people to move this puppy around, as in to tilt on its side to gain axcess to the bottom, I ended up doing the adjustments vertial and reaching up though the axcess pannels on the base.
I really like the unit and the way its made, but the directions could have been a bit more clear on adjusting the upper head, especially for a first timer, and adding a bit more clearance to the sprocket/chassis wall would make any adjustments much easier, if they were ever needed.
I'll attack it again this weekend, and hopefully be able to try it on the couple of pieces of walnut the guy at work gave me.
Al who's down to two band aids, and healing....
