Anyone have any ideas on repairing the spline inside a door handle? Obviously, finding a new handle with a good spline is the number one choice. However, I recently had the inner door handles for my '51 Merc rechromed starting with the best set I could find. Yesterday, the spline on the driver's handle bid it's last goodbye. I'd love to fix it since the chrome is brand new. I thought about sleeving it with a new spline, but have not found such an animal. Second to that I thought about cutting some undercuts on the inside then filling it with JB Weld or the like and sliding it back onto the greased shaft (so I can get it back off of course). Not sure "new" JB Weld splines would hold up. Anyone, anyone?
