When is one "too" far gone to salvage/true up etc.??? Pix are good for me. Won't say any more than that for fear of flame-age material!!! Thanks in advance!!
Unless the bar is a very expensive or rare vintage model, anything that requires more than a flat file to repair is too much for me. Lots of inexpensive bars available for firewood duty.
I will run one forever. Bit usually a file is all thats needed. But if you use them a lot you can wear metal away. But cheap bars are readily available like MM said and work fine.
A bar is no longer repairable when the groove is so shallow that the chain does not ride on the rails. Or it's bent. Just about everything else can be repaired.
