Its worked very well Daniel, also helps with spinning the engine up by hand.

I like to run accessories of my OKMO B01 but I don't like flat belts. I machined and hobbed this aluminium drive pulley that slips over the flat belt pulley and is held on with a grub screw and its worked really well for the 'O' belts that I make up.
