Re: 1/4 Inch Chain

I wonder why Oregon went with a low profile 3/8 chain versus a low profile .325 chassis for the smaller chain?

I can only assume Oregon followed an industrial trend .Passed the late 70's early 80's Poulan and others hada variety of smaller displacement saws that required smaller type chain .It would obviously be more cost effective to produce low profile 3/8" as compaired to 1/4" .

Even if you go back as far as the piston ported engine design becoming the norm over reed valve engines .Most of the reed valve Macs and Homelites used .404 chain ,heavy duty stuff .The piston ports mostly used 3/8 chain,lighter,less bite .It utilized the speed of the piston ports where as the .404 made use of the high torque of the reeders .
