Chainsaw Repair

When you are filing out in the woods, it seems to be taking up a lot of time. About 10 years ago I went to the woods with my wife and two grown grand daughters as helpers. Took a extra chain with me too. The wood was dry small blow downs from the previous couple spring ice storm. Chains didn't stay sharp for toot. I couldn't keep the women busy. Spent all my time with the file. I guess I needed a filing jig and put one of the women sharpening the spare chain? Or I just sharpen chains and let the wife run the chainsaw? She does OK with a under 50cc chainsaw. That wood was surprisingly bad on chains.
