professor95,
Thank you for your response. I don't have a meter to measure the draw from the chainsaw, are they expensive to get...
RollingCondo,
I'm at work right now, but the extension cord seems fairly heavy duty...
Check out the P3 Kill-a-watt for a good all around meter.

You'll find lots of uses for it after you get one. They can be had for under $20
You would be well served with a 12 gauge cord or heavier. Some so-called heavy duty cords are only 16 gauge and about worthless for anything other than a trouble light. The gauge will be imprinted into the outer sleeve in tiny print.
P3 kill-a-watt will give you power factor, wattage, kva etc while in use and would be interesting to see the changes as you apply the chain to wood.
You will need a clamp on meter. You can go to your local Home Depot or Lowes. It has to be capable of reading in-rush current. That is the first instance of power consumption in the first 150Ms.
An electric skillet is a resistive load. Your electric motors are inductive load. Inductive loads as referenced by the professor, have a high start requirement. (locked rotor amps)
My pancake compressor needs around 35 amps in the first 150Ms. As long as it starts in the first 400Ms, thus reducing the load requirements, we are good.
Your 3.5 horse power motor is the max horse power used under load. Same with the amperage, 14 amps would be the energy your motor is rated under load. With the P3 kill-a-watt, you can see the amperage climb as your motor is put to work.
