I got the parts back from anodizing yesterday and assembled them last night. Everything went together well and the bearings for the tilt went in with a nice sliding fit.
This weekend I am going to machine up the base that this sits in, it will sit on a thrust bearing and another taper bearing for alignment. I also have some worm gears to help with adjustment.
This thing is getting heavy! I am thinking about building it on a small trailer so I can just drive it where I want to put it. The trailer would have outriggers for leveling and getting the wheels off the ground.
