Speed cutting saw chain

[@cut4fun50]

NICE learned some tips been working with chainsaws for 50 years. Always room for improvement

Love these little tips and tricks. Can’t wait to test it out

One of the most technical and reasoned explanations of how a cutter works and how to improve cutting performance that I've seen anywhere. It would be nice to compare the results of your filing modifications to a stock chain by performing one of those classical cutting time comparisons. It would also be nice if you could make your videos more frequently......and I'm subscribing on the hope that you'll do so.

Thank you- caution on the 1 cut time trial. I think a true comparison should be done after 3 or 4 tanks of gas cutting the same wood. Even a well filed round filed chain will cut good. It’s the duration of speed and smoothness over time where the properly square ground (or filed) chain really shines.

Knocking the heels off helps when pulling long coping notches in log work. The reduced friction because of having a bit less metal adds up when running a lot of cope. Shallow rakers (depth gauges) allows a comparatively less `chattter' when brushing sadle notches and such. No matter what you are doing... the working corner is everything... if that's buggered up... your out of luck.

As Always - Good info John.

Thanks Tim- price of fuel, we gotta get every once of efficiency we can.

super helpful vids by the way, there's not the depth of experience in Ireland that you may enjoy beyond where you live. Forestry is a new thing here. Since the foundation of the State, forest cover in Ireland has grown from 1.4% of the land area, to the current 11%. So we learning, you helping, all GOOD..

I remember being in Scotland for the World Logging Championships and thinking, where's the trees? The history of the land there is fascinating. We do travel and train forest workers if your interested. Maybe get a group together and I could come over. Check out our web. site www.woodlandtraining.com

Awesome info. Nice efficient job on the freehand grinding mods, and you make a great point about "white knuckling", all the more valid from production cutter's perspective. Cool to approach the chain tuning process from the angle of smooth relaxed cutting. The inward bevel on lower side plate is interesting, one time I tried filing under the square corner with round file at a standard sharp angle, making a big hook with square filed tip roughly the height of the chip. I found it to cut fast, but aggressive and a little wild, the cut would easily drift with slight torque on the handle. Seems like the inward bevel would have the opposite effect and help focus the cutting, never thought about the drag forces...definitely have to try it out...curious how it reams out a cut under bind and shaves compared to the standard full height side cutter. Thanks!

I actually like the ability to drift in the cut with a little torque on the handle. I did the same thing as you, couldn’t figure out at first why it was drifting. Now I know it happens and try to use it to my advantage.

Really interesting material here John. I'm really curious about the bevel angle grind on the bottom of the side plate that you describe here. I've never heard anything like this before. I would love to see some before and after timed cuts with the mods. You're definitely a great resource for us - thanks a lot!

[@LGTrees]

Thanks!- comparing times is tricky stuff. We're not going from just OK to incredible fast. Just taking fast and going a little faster. I show what I'm doing in the video "Pro's only please" Cutting the back off is very easy and only done once. Keeping the side plate caught up with the working corner I do every 2 or 3 sharpenings. Still quick if you have a round grinder. Need to be careful not the dull the very top.

Dad kept his guages aggressive and uneven, would almost jerk the saw out of a young man's hand. I like mine to cut smooth steady.

[@timfromtang]

Do you use some sort of custom depth guage filing jig to file your rakers down? Is there a way to accurately file the rakers beyond the standard 25 thou without a filing guide? How do you measure the height of the depth guage relative to the top of the tooth? I've been using the oregon guage and filing to 25 thou for years, often felt I could use a bit more bite.

[@LGTrees]

Check out the video- Filing the depth guage - I use the file-0-plate. I file the soft wood end back (small round file) just a bit so it allows a bit more depth gauge to stick up through.
