Hi dorgitt, the pic shows the concept of my beam, but the Wasser build variations would fill a forum on its own, it all depends
what its use will be as that governs the planning and layout as im sure you know already, heres a link to stf wasser forum so you can pick up on the basic requirements to build them.

I would source a 2.1 crank over the 1.9 that you already have, just for the extra torque it will provide, or you can stroke it with a T1 crank, but hey, its all on there anyway, and will keep you reading for a while, and thanks for your interest, i will post up some more pics of the motor install as i get time.
