Lo pr bar and chain for vintages

[Stephen s]

I’d like to put a special ripping bar and chain on my partner R12 , if possible a 26 bar , do I have any hope? Dose the lie pro and fewer cutting links mean I could go up to a 30 ? Any help appreciated, am happy to use second hand bits

This may throw up more questions than answers. It would be useful to know the intended use, presumably occasional milling?

 

I'm not sure of the wisdom or real benefits of using 3/8LP on a biggish saw, I guess you'd be sharpening it fairly frequently and the kerf isn't actually that much smaller than 404 iirc, something like 15% smaller. The milling specialists will hopefully be able to help.

 

I think the bar mount is Big Husky (D009), which gives you lots of options, and the K12 is in the 4-5HP area. That's comparable to say a Stihl 441 which has a max recommended bar length of 25" (standard 3/8 pitch chain). So you might get away with a 28" bar and regular 3/8 pitch chain, something like Oregon RD (Rip Cut) or even Powercut 72/73, JGX is a skip version which might help.

 

 All a bit immaterial though if your saw won't oil a long bar properly, so that's first on the list.

Hope that's of some use.

My partner r14 was 76cc but 8krpm, ran a 14" bar.
I don't know the r12 but it's probably pushing it. What the cc?
What length bar do you use for cross cutting?
How about file the chain to 0degrees with the bar you have?
If it's under 70cc you'll probably just knacker your saw.
