Pitch and guage question

[Kenskip1]

I have a question reguarding the pitch and gauge on my saws.
My 028 has a .325 pitch and a .063 as the gauge.
My 041 has a 3/8 pitch and runs a .050 gauge.
Now here is the question. Seeing as the 3/8 is a bigger chain, why does the gauge not correspond with this? I would think that a 325 pitch would have a .050 gauge, and a 3/8 would have a .063 gauge. .063 is larger than .050 and this should be on the 3/8's bar. What am I missing? Thanks, Ken

good question ...... you beat me to it .

There is no "standard" - just whatever has evolved... Applying logic to evolution will fail The strength of the chains has little to do with the width of the tang, and even if it does, the chain is so strong it doesn't matter.

Chain Gauge might be a system that works backwards, like the American Wire Gauge (AWG) system. For every three AWG numbers you go up, the cross sectional area (and hence the current carrying capability) halves. It's a logarithmic system.
