In my case, I didn't need the strength (or the expense) of a commercial
sidemount to handle a C3-E. A neighbor who builds drag racing cars did the
welding on mine, very similar to Stan's in overall design, but with a block
of high density polyethylene for the top bearing and a permanently fixed
gate arm. The only difficulty with the single-arm "gate" design is the
need to rotate the mast in the rotator to set the direction, since there is
no vertical tube in the gate for the mast to bolt to. Not a big problem.
