This is not my advise but 1 I found on the web

Engine size, or displacement is a rough measure of what the power of a saw will be. Displacement is measured in either cubic inches CI or CID and cubic centimeters or CCs. CCs it the most common method of measuring displacement today and you can use an online calculator to convert CI to CC if you need to in comparing saws. There are numerous other factors that determine the power output of a saw but I won’t go into those here. The table below is a guide that I’ve personally developed from experience:

Up to 30cc is adequate to run up to a 14″ bar

30-50cc is adequate to run up to a 16″ bar

50-65cc is adequate to run up to a 18″ bar

(I would be hesitant to recommend a saw larger than 65cc to a first time user)

65-80cc is adequate to run up to a 20″ bar

80-90cc is adequate to run up to a 24ö bar

90cc+ You’d better know what you’re doing and what types of bar you run if you get into a saw this large
 
Seems a little short on the bar length...


Maybe for a firewood saw, you would keep the bar length that short, so you can pick a saw that will buck up logs swiftly... or if you only can run full comp chain. Which is, highly unlikely.
 
I'm afraid that I don't like this recommendation. Many saws today with smaller CCs can pull longer chains. The second row of this "table" starts to fall apart and so does the third row. After that I trust nothing.

Source? :monkey:
 
Wow, I run about 4" and longer on everything than what that chart shows.

I seconded the back ache, LOL.

I run 28" on the 441 and 660's ........ and 24" on the 361.

I'd say the chart would be OK if you were doing nothing but bucking tough hardwood all day.

Other than that, they are quite a bit short.
 
Umm, Ya, OK... I am speaking for all the PNW saw owners I'm sure.

Oh no, don't let Stevethekiwi see it. He may learn something.

Al.
 
Don't let Sawtroll see it he'll say that definatly every length is to long and that there are only 3 lenghts :
1) for saws under 60cc only 10inch
2) for saws from 60cc to 85cc only 13inch
3) for saws above 85cc only 16inch

Defenatly not more!

:hmm3grin2orange:

:yourock: Sawtroll

No second column for skip type chains? No third column for hard vs. soft woods (as previously noted)? Nah.

Having said that, the site does have some good information available.

Well, that was an interesting read!

I really enjoyed the part about top handle saws being used for limbing, and only up to 8" dia. wood.
I wonder what he would say about my 200t, with a 16" cutting through 14" wood?

I mainly cut firewood, and hardwoods at that. I'm not an idiot, a 361 will eagerly pull a 25" in Hedge!!
Yeah, the 25" on the 046 BB is SWEET!!! But it has plenty of grunt to pull the 32" in anything I want to put it in!!!

I think this guy needs to get out and run a few more saws before he spews off at the mouth too much more!
