Tell me about this adjust o jig and where to get it,sounds like a neat thing.I like anything to make things easier.I don't mind the mess it is easy to get lost in the build.I am thinking of the 120 for a winter project so I will be following your build actually it will be one of a few winter projects,we get a lot of snow and cold here so I am stocking up on things and I can't do any shoveling anymore so hey more time to build.
