Love your work Colin, if you manage to get her to Corowa next year I hope to get a good look over.
Your decision not to angle the power pack was wise, because 9 deg is bugger all, as long as the crank/output shaft are on the same linear "plane' as the diff pinion shaft. To angle the engine/gearbox toward the diff to reduce the shaft angle would only have introduced a nasty shake through the hull at speed because the tailshaft would have been "out of phase". Crank bolt & output shaft centres should be equal-distant from the hull side. You probably have already done this, but make sure the crank centre bolt & centre of your output shaft are equal-distant from the hull floor for the same reason. The carrier pinion shaft enters the hull level with the floor & hull side..
I see you have solved some of the engineering problems I was scratching my head about on my replica Vickers, such as how to re-attach track guards etc.. but I am wondering, have you, in the past, mounted the engine mounts direct on the floor before? I was considering it, but was worried about torque flexing the floor plate, and had decided to install the engine/gearbox in a cradle, attached to the floor and hull sides. Is this how a 2pdr engine mounts are normally mounted?
