Hi all,
I've my conversoins problems with a couple engines with one exception: the prop hub.
I first thought of spininng an aluminium cilinder, and machining two screws inside of it; the first one to screw the prop hub to the engine, and the other one to screw the bolt that holds the prop.
However, I don't like the idea of screwing on aluminium, and I fear it will come off. For security purposes, I thought of adding two M3 screws so that they push against the engine's aixs thread and the bolt that holds the prop (to make sure they won't turn loose).
Any of you has tried this befoer, or knows of a better prop hub design?
