Well progress is slow, but today OH&S was closed, so i had the Proof Of Concept run.
No OH&S inspectors in site. Wife on a Christmas cruse with the sister and all the kids.
The Pulley came from a bearing supplier here in Brisbane, and when he heard what i was doing he though in the belt. $55.
Gates one too, nice your man. Pulley is 160mm, so at 1500 rpm the engine is doing 1760 rpm. the balancer shafts in the engine seem happiest at this speed.
And the temp didn't change much. Load was a 2400 watt heater. ran for about 15mins before the rain, ended play.
See voltage on the meter on the dog box, and we all know meters don't lie.
So the next step is the AVR and its box, and build a frame.
All the best to everyone for christmas, and thanks for all the help.
