The turbine is nearing completion. The disks are all chosen, spacers made and checked. ive ended up with 6 disks. the topmost will have some magnets on it, to drive a wheel outside the turbine housing. the outside wheel , having a matching set of magnets on it.
at least im pretty sure thats how its going to happen.
also started sanding down the old fireplace timber for the deskfan base. taking longer than i thought it would. but almost done. Have changed how thats going to be made now too.
i'll put some pics up tomorrow, im tired
