Quick update on the starter additions. Have the clutch hub finished, just need to drill and tap a 3mm - .5 hole for the locating pin and install the magnet. Hoping to remove the rocker arms and covers to gain access to the right side cam housing. The rockers pivot on a screw pin that has a slotted head. Broke every tool that fitted into the slot, ordered a few
Chapman #89 bits, these look to be a quality tool, I hope the bits work. Once the rocker covers are removed I can determine if the area selected to mount the starter motor and reduction drive is suitable. Right now on hold until the bits arrive.
The prop nut kept the hub engaged on the original design, I planned the extend the threads and make a flange nut that fit into the counter bore on the prop hub. I would like to know what steel the prop shaft is made of. It is 10mm -1.25 thread. Bought a rethreading die at the local Ace hardware, it squealed like a pig once it hit the unthreaded portion of the shaft and it was well lubricated, it broke shortly there after. Purchased HSS threading die but waiting on a handle to turn it, I suspect it will be unsuccessful as well. The fall back plan is to make a nut 12mm in diameter with a larger hex on the end and counterbore the front of the prop to accept the 12 mm nut, the back side will be the standard 10mm to locate the prop.
