After being gone on vacation, vehicle maintenance and redoing some things around the shop I finally got back to the BH
The next section to do is the station at C-S. It's pretty hefty tubing at .065 wall for the landing gear shock strut attach point. I made a jig according to the plans and tacked it together. The engineering change in Beartracks allows you to substitute the small piece in the middle to a thinner wall to save weight, but I just used the same thickness throughout.
Once that was done, I had to establish a reference point for the height of the top tube, along with the centerline. I did this with a level across the door threshholds, centered and perpendicular to the centerline.
