I overtightened one of the screws on my 395's inner dawg when I had it off a few weeks back. Now it seems the threads inside are completely stripped. This had happened on a used 385 I bought a few years back and my shop recommended a heli coil. That worked for about a year and then blew out entirely to the point that welding the aluminum was necessary which I didn't attempt. I just ran it with the outer dog and sadly ended up wrecking the whole saw a week or two later in a completely unrelated felling incident. Anyway, I seem to remember seeing a comment sometime ago laughing at the "usefulness" of heli coils in this application. Anybody got a different solution?
