Stumpy's drivers were keyed and loctited. No cranks on Stumpy so orientation is not a problem. Topsy's drivers were keyed and loctited. Topsy may have cranks, but they are for show only (both axles are chain driven) and they will be fitted as fly cranks on axle extensions, clamped so that adjustments can be made.

Not had one move ever. Regards Clif ----- Original Message ----- MODEL ENGINEERING DISCUSSION LIST.
