If your the type that likes to fabricate and has some patience, I suspect it can be done. Its a lot of on again, off again, to see if there engaging. Then running the motor to see if there pulling in. Me and a friend spent quite a bit of time one day trying to make some but never could get the tension just right. These assemblies are plentiful at Tomahawk. Most are in different stages of completion but I did find one with all the springs. Doug Penn had a complete one on eBay not that long ago.
A "Boathouse Repair" is one thats done without having tools or the skills to do it properly.
