Anyone ever considered replacing the phenolic rubbing block by unriveting it, making a new block, and riveting it back together? Seems like a lot of good points get tossed because of the rubbing block and the point surface itself is good.
Personally I would think Nylon would be a far better choice. Nylon-6, Nylon-66 or Nylon LFX have far better anti-wear properties and are self lubricating. Regards, Bill
