Safety Chain vs. Semi chisel vs full chisel!

[AmericanPiddler]

Hey all,
I hope this is in the right spot, but would like some advice and use it in this video!
Planning on A YouTube video this next week or so, I'm going to compare the homeowners safety chain verse the non safety chisel chain! I'm going to use the Husqvarna 455 Rancher with a H47 chain and compare it to the off the shelf big box store H80 chain I will also throw in the Stihl 33RS3 chain amd possibly the H46 or H82 Chaim Any advice on the project and possibly what you'd like to see thanks! Here's a link to my YouTube channel called American Piddler!https://www.youtube.com/channel/UCID8zazGyhxjMZC4JmvCrhw

Is it possible to throw a square filed chain and/or some Oregon offerings in the mix? I haven't kept track what Husky chains are actually Oregon versus their own these days.

Secondly, if you are running out of the box chains, you risk deviations based on how well they were sharpened from the factory. If you were to say have the same person sharpen all of chains and adjust the rakers to the same depth you can remove that variable from the results.

I understand that if they are all sharpened by the same person that eliminates variables..... but honestly is the average guy going to do this? I'm looking for ideas on tests to run on these different chains

If you are talking the original factory edge this is done by a robot/s or automated machinery for most of the well known brands in some cases Blount(Oregon & other) the parts that make up the chain are produced in different facilities & brought together & assembled the New out of the box chain is not always the best example

The average guy is not going to be concerned about a few seconds difference in cutting speed. To be a fair test, you need to ensure the chains are sharpened consistently, run on the same saw, same rpm, same pressure on the bar, same diameter and condition of the log, same ambient temperature.
You could also test each chain out of the box and then sharpen each one and retest to look for differences.

Just a thought: unless the end user throws the chain away when the factory edge is dull, most of its useable life is spent with a cutting edge created by someone other than the factory.

I've had factory loops cut like lightning and some that would barely cut. Taking a chance on a factory cutting edge doesn't showcase the actual ability of the chain against its peers.

After you figure out best sharpening practice...

I would suggest a measured amount of fuel (5 oz. or whatever) for each chain and cut cookies off the same log until the saw runs out. Most cuts wins - of course results may vary with type of wood, dirt in bark, and phases of the moon. This would show which cuts faster. If safety chain was 2% slower for example it's probably by far the best choice for most firewood hacks like myself. 50% slower changes the equation.

It may also be interesting to know how many cuts are made until the chain exceeds XX pounds of force to complete a cut. This would be more challenging to measure. This would show which stays sharper longer, again depending on wood type and conditions.

I like the idea of say a few oz of fuel for each chain I have telephone poles that I could do the cookie cuts on that are uniform in size...... if we ran the test back twice ir three times it would show sharpness.... I also would like to show the differences in kickback because the differences between the H80 off the shelf box store green/safety chain kickback compared to the H82 have to order or go to a pro shop to buy kickback is tremendous.... also if the operator wasn't familiar with the saw how quickly you could hurt yourself being careless with a chisel chain..... my hypothesis in this test is that the chisel chain is at least 25% faster and more I'd even say that more efficient with the saw working less tha. With the safety chain.....
