Nice Inventor work! A+ for the gears and sprocket if you made them yourself?
Looks familar!
I would be interested in the drawings and would check them out for you.
Coming from an experienced Ball Lock transmission team; this type of transmission is a winner! Shift any transmission once your hooked; shift a Ball Lock twice and you will never turn back!
Any idea how your side plates are going to look and what tooth count are your gears?
Now that you have the hard work done, get those machines running!
One thing that could shed some wieght would be to get hubless gears or machine those hubs off.
