Why is experiment #3 so different? Because it was something convenient for me to show the large voltage drop that occurs at a typical motor under startup conditions and a long #12 wire. With the current blade on the machine startup is quite quick, probably less than 1 second. With a maximum blade the startup time is several seconds and maybe 70 amps.
I am going to guess that the voltage at the freezer may drop to a value in the range of 70 to 90 V during startup. If this is the case and it lasts for a number of seconds, then it might also trip the breaker at the end of startup.
Some voltage measurements from the freezer installation will be important information.
I can not tell you what the voltage is when under full load on the saw. However, on thick wood you can easily stall the motor if you want. This has nothing like the capability of some guys that connected a chain saw to a V-8 engine and cut thru about a 2' diameter tree in few seconds.
