Good enough for me Dave. If you say I'm good, I'm good.
That 6400 will wear a 20 or 24" to beam cut.
The BB one will get some porting/tweaking to do the medium duty work with a 28" or 32" I guess. If it burns down, to bad hu. Then Ill get 7900, 7910 or 7300 top. The Os might be better than the tens in this application. Does the early jug have a larger exhaust port and casting area?
One stock 660's is rigged with a 40 roller. No aux oil, yet.
One is not set up yet.
Can a better pump and/or gear be bought or is it time to make one mo betta? Rarley run bars bigger than 28. Have a 36" 3/8 050. Never used it. Just got a tip for it. Needs a hammering in just a few spots. Good rails with little wear. All beat up fat nose tip from boring.
A twin head bar in 44-52 would sweet.
Not planning to push or pull any of the big saws 80cc and up for more than testing single cuts. A yoke will be built with a mini winch to pull saws. Won't matter how the log lies. Add weight if needed.
