I am looking to buy one of the electric granberg file-n-joint units. I have the hand one and it is a pain at times and would like to go with the electric one so its one pass and its sharpened!
Don't have the stone or the bar clamp/angle dealio though, I dug around in the box it was in and not seeing those parts. Not sure on the story, may have had those parts robbed to repair another one at some point. The shop used to be a Grandberg vendor back in the day.
I think it would work as the "grinder and joint" as I'm pretty sure that's just the same grinder without a bar clamp and angle guides... I believe? I don't know if that would be of interest?
