Re: 1/4 Inch Chain

Stihl sells the best quality 1/4" chain with a boat tail mod on the cutters for carvers running the tiny dime tip bars. Stihl sells the carving bar too.

As I posted in detail over on Tree Worlds site in the Stihl 020 chain thread, I explained about how the industry changed over from 1/4" chain to 3/8" LoPro extended pitch chain in the early 1970s.
Since the 1960s low powered consumer saws needed the little 1/4 chain to make them usable to cut with. But as the consumer saws out numbered the commercial saws the 1/4 chain got too expensive to manufacture and supply the cheaper saws with. The 1/4" chain having many more pieces for every foot compared to 3/8" was much more expensive to manufacture. So an Oregon sawchain engineer invented a  3/8 pitch chain with 1/4" chain sized cutters with a base extended to accept a 3/8" pitch chassis.
The Oregon 91 series 3/8 chain was patented and on the market in 1975. Stihl introduced their Picco chain along with Windsor's chain in 1979.
But the sawchain companies never discontinued the little 1/4" chain, I guess there always was enough carver market to keep it viable in small inventorys at a high price tag.
Making a living with a saw since age 16.
