Keyed 3-4 Hubs Re-Keyed?
I worked in an industrial manufacturing area for a while (Permatex) and remember broaching certain gears for new keys at times. Sometimes it was a key size change for a different shaft and other times it was to save an old gear to make it fresh again.
Has anyone re-broached a VW 3-4 hub? I would think a new key slot cut maybe 120 degrees out from the first one would make them servicable again on hubs with enlarged original key slots.
091 3-4 Keys
I know the stock 3-4 keys have a tendency to collapse or break the side walls, has anyone tried adding a little weld inside the keys instead of converting over to the 002 key style? I could see this being an option when wanting to use stock gears and hence stock synchros in an 091 and trying to give a little more life to the transaxle.
Brazed Fork Repair
I have a lathe and think a simple tooling set up could be done to quickly machine old worn forks that have been TIG brazed with Silicone Bronze to build the pads back up or add pads to early style forks. Would really love to make this work with early forks to get the circular fit up better so the whole fork pushes against the slider and not just the upper or lower portion of the fork. Any tricks for forks that tip in and out on the slider?
