“I’ve been searching (without success) for a drive link grinder. They consist of a twin link-grinding wheel, and they grind off any burrs that may be on the chain’s drive links. The only place I’ve seen one is from a company out of Scotland. I’ve also heard of, but can’t find, a bar grinder that takes old, worn-out bars, grinds off the old groove and recuts the groove. Anyone know where you can get either of these?”


“I had some problems with chain jumping off and bars that wouldn’t run true. I went through the process of having the bars ground at the saw shop. Trying to fix the chain with a file sucks. I got enough money together and set up my own bench with a spinner and breaker. Making your own chain loops is quicker than trying to fix one with banged-up drivers. As for the bars, they are expensive, but when they start to run off, it’s hard to get them back even with grinding. So, all this is to say you could go get that equipment, but consider how many bars and rolls of chain you could get with the same money.”


“If your bars are that messed up where you can’t fix them with an angle grinder or whatever, time for a new one. Don’t risk your safety to save a few bucks!”


“At around $90 for a 32-inch bar, I’ll pay to have it repaired professionally before I’ll take an angle grinder to it.”


“You guys are either really hard on your bars or that chain you are all running is harder than the bars. I use a flat file to remove burrs and the Pferd bar dresser to square the rails every time I put a new chain on. Never had to refurbish a bar (other than a tip replacement). Maybe you are running your chains too tight or dull.”


“Neither. After a lot of hours, a bar’s rails will wear and need to be narrowed down. Many of my bars are years old. I have a bar rail closer, but it does a lousy job. I also have a Pferd tool for squaring up a bar, as the rails can wear unevenly.”


“I’d just stop being a tightwad and buy a new bar if it’s that worn out. I mean, all the trouble of sending it out, waiting for it and getting it back. Now you’re out a saw for a length of time. Let’s be real here.”
