.404 to 3/8

It would prolly be easier for you to convert it to .122 on that harvester chain.

 

Stubb, Windsor made a lot of bars in .050 for reduced weight. They would also make their bars slightly slimmer if they came in 050. The savings were in the ounces, but they were still lighter than their stihl counterparts by a good measure. In the PNW, .058 is non existent. It's 050 or 063, and Stihl bars were just as likely to be 63 as 50. This is my 046 wearing a 28" 050 Windsor:

Ah yeah. Dual ports.

 

 

Wow, we've dragged this poor thread way off topic...

Never been one for narrow kerf myself, but my 385 does have the dogs and wrap handle, doing the muffler this weekend

It's not really a narrow kerf, just a narrow gauge.

Either way, I still don't see the point

Some conifers, Doug Fir especially, are very fibrous and wet. On a long bar, like 32-36" which is typical use for a 71-93cc ported saw in DFir, the chain will be loose enough for the fibers to get in and gunk them up. A more narrow channel makes it more difficult for the fibers to get in, and it more easily cuts and minces the fibers that do. It also makes a long chain a bit lighter. And some bars are made more narrow for 050 gauge chains, making them lighter again. A 70-93cc saw in the PNW is not a ground saw. It is a felling saw. We drag it around on the side of a mountain all day. So a few ounces here and there add up and help. If you throw your chain, it is also easier to fix the links by hand.

 

Here's the noodles you'll get out of DFir:

One last little drag then ........

Thanks for backing me up there wyk ! It was a Canadian saw but the bar was as an Aussie GB bar . I honestly think you can get any chain , in any pitch , in any gauge , in any driver count you want and someone will have a bar for it . Seem to remember having some slim gauge longish Windsor bars at some time ....

 

The chain is 72LPX = large 3/8 tooth .050 [1.3mm] drive link years back most saws ran this chain, today only old Mculloch and Echo saws are fitted with this and as bars get harder to find most users change to 73LPX/DPX on 1.5mm 0.58 guage.
