Mast Tang Replacement

[Brion Toss]

Hello,
Tangs can outlive chainplates as corrosion is usually not as severe. But tangs are often peculiarly undersized, so suffer more readily from fatigue, especially if there are lead problems. But that is a moot point here, as even in a best-case, yours are aged, and of questionable original quality. New ones are straightforward to get, in a variety of materials. If you do replace them, check the load numbers, get the ideal leads -- generally work to avoid cloning errors.
Fair leads,
Brion Toss

Ahoy Brion , wondering what would be "Cloning Errors" on mast tangs ?

Do you suggest by this , that the tang displayed in the Benjiwood photo needs a nudge more shoulder area around the pin hole and screw holes and this should not be repeated/copied when fabricating new ones ?

Hi,
I don't seem to have a picture of the tang here...
