I had no idea what he was doing until 3:20 mark. I thought he was making room for a hydraulic jack or something. No, that's pretty cool.
So is that chainsaw surgical sharp or what? There's no way I could make those cuts with any chainsaw I've ever owned.
When I lived up North, I cut and burned 5-6 cord a year. Keeping a sharp chain makes all the difference. A sharp chain is not only faster, but easier on your saw. Sharpening was just part of each day of cutting.....and sometimes during cutting.
He's likely using a chain with fewer teeth & no antikickback teeth will cut very fast. Also the saw motor is worked over to run faster & stronger. It's a good idea NOT to use a saw chain without antikickback features unless you are very skilled & willing to take the risk of getting very hurt. Tree guys I've talked to have saws that are very fast cutting but unsafe for the average person.Quote:

These wimpy little 50 to 65 cc saws I buy don't seem to have enough power to kick back anyway.
Sharp teeth, LOWER depth gauge*, equals very fast cut.
* Its the part of the tooth that controls how thick the chip is.
I'd like to take a lesson on chain sharpening from him!
A little late, but I found I like the bench top sharpener from HF. Inexpensive but does a good job. Since gaining experience, I can't stand the chains with anti-kickback nor the depth gauges which are bent.
I also prefer the skip tooth, but can't find them as easily in my area.
These preferences do make it much more dangerous, but you get a lot more work done.
I always have 3 extra chains so I can just change them as needed in the field.
