The Holy grail?

Its a tiny difference tho widthwise?

There is no assumption about it. All three cutters are identical on those chains. The width of the drive link doesnt dictate the width of the cut in the wood....the dimensions of the cutter does.

Cutter is attached to the drive link though, making the drive link thinner moves the cutter towards centreline of the chain ... small difference to kerf but still .....

If a cutter is 4mm wide irrelevant of its location within a bar it can only make a cut of 4mm in wood???? No more, no less.

Trailoftears -  do you have the 2 rim sprickets to hand, the 7 tooth 0.325 and the 7 tooth 3/8 lopro ?what can you tell us about the outside diameters?

It would be interesting to measure the gauge of the steel the cutter was stamped from too as this would be an additional tiny reduction.

 

Mind I am only hypothesising on the logic with no practical experience of narrower gauge chain.

Think that may be something. All chains have considerable  side to side lean action/chatter even new & esp as bars wear narrower drive links may keep em on the straight and narrow better?

Sounds like we are on different wavelengths. ... ?

The teeth, left hand and right hand are separate items attached to their drive links on opposite sides of the drive link...

The .325 is on the saw.The picco rim sprocket is,say a third bigger than the .325 rim sprocket physically,also just measured the external rim width slots on the picco super rim,and I would say its bang on 2mm.

And what about the outside diameter ?

I will whip the .325 off later,hopefully a piccy pr two!
