Added a universal joint to the rear stand, using 22mm od tiube down the tailwheel attachment points, into the UJ, and then another piece of 22mm tubing into the engine stand mount. This takes all of the twisting action casued by the eccentric axes of rotation of teh tailwheel spring and engine mount. Spins beautifully, and by a complete fluke, also ensures that the cockpit floor area is completely horizontal!
Acquiring a length of scaffolding pole to fix the two engine stands together; hopefully it will arrive this week
