I've been trying to save money on this thing wherever I can, but it only leads to one nightmare after another. I've ground down the pins on my 415 H chain and it still won't come apart. I have a chain breaker but the 415 won't fit in it. Where can I buy a custom length of chain? Every single day is a new set back. At this point I'm willing to pay twice as much for a 14 link length of 415 H chain.
