My Chain whips are made of hot rolled steel flat bar, the chain sections all join the holes in the flat bar, with the 3 piece
chain links for 1/8" chains, though the rest of the chain is derailleur chains,

It was the pins into the holes in the steel flat bar that blew out because they were 1, short ..
and 2, the links had to stretch the holes to get the pins out.. insecure thereafter,
same reason you now only shorten chains, with flush pins, like derailleur chains are now.

then I put a tube handle on it, So they're a half M + long now.
