Critical dimensions are: hole spacing for front iron, three ½ holes, 60mm
between lower and inboard, and 185mm between upper and lower.

Second important dimension is distance between hole center line of angle and
center of pipe, should line up with center of oil fill tube, to balance fore
and aft.

Third important dimension is to position angle in relation to the channel so
that crank is as close as practical to center of pipe, so that engine is
balanced when rotated up 90 degrees. I didnt measure them exactly, MK1
eyeball tolerance. If anyone really needs a measurement, I may get to it
later this week.

Drill four ½ holes 90 about 1/3 from one end of pipe. The last hole are for
the rotating lever, my hole there is too small, but didnt have time tonight
to measure that either.

You could get away with shorter pipe and total standoff from back of stand.
Gussets may not have been necessary, but I get carried away.

Your results may vary.

Looks great Craig. I see you have the pivot aligned with the engine CG
more or less.
