I would like to find out from some of the more experienced users in here whether or not using a spinner nut on a threaded rod as a means of attaching the prop to the hub is as safe as using just a hex bolt.They work just fine on glow engines so I can't see a reason why they shouldn't work well on these gassers.I'm worried about the degree of potential kick back and any safety concerns that may arise from such an incident.The main reason for going this route is to allow me to get more purchase on the crank to make it easier to turn over with my 18 volt cordless and Sullivan starter hub assembly that I use.It also helps keep the starter cone in one fixed location minimizing both vibration and any potential for starting accidents.I was thinking of Loctiting the rod into the prop hub assembly and just tighten the prop onto the rod using a 5/16"-24 safety spinner/nut and a through metal rod.Would this suffice?Any other ideas on this mostly gladly welcomed.Thanks guy's!
