Not to get too far off topic, I scattered the front cylinder on a Knucklehead at 75mph. The big end, although one piece,was not the worst problem.
After months of trying to start the project the mists are clearing, so I can at last make a start on the 1/2 size 650 twin Triumph engine. Most drawings are complete except for the cylinder head and rocker boxes, more thinking required!!Most materials resourced, some large lumps of ali for the crank cases, cast iron for the liners and flywheel and precision ground steel.I will start with the con rods to get my eye in, as it’s some 30 years since I built an IC engine, namely the BR2 9 Cylinder Rotary, lets hope the memory of how do’s kicks in.This is part of the GA drawingMikeI like the big happy face drawing..........oh .i see it now !!!!!
