390 or 3120xp

[Hammered]

I have been saving for a 390xp and an neighbor offered me a lightly used 3120xp today for the same price as the 390 was going to cost me at the dealer.

Milling and the odd big tree use.
I will be running the hell out the saw.

I have a 070av but not practical as it sucks a gallon an hr and destroys hearing flesh for a mile around.
Love this saw as it made my house.
Selling it I decided as it will just collect dust once I get a bigger husky.

I'm leaning towards the 3120 with the hope it's better on fuel than the 070.
390 will have the power I need for milling but maybe a bit more hp will help me get more cubic lumber per shift is my thought.

Any input appreciated from the group.
I'm getting one or the other next week and grateful if you help me spend my hard earned $ right.

Also like to say this form and the folks that make it happen are awesome.
I'm addicted
Thanks

3120 greatly stomps a 390 for milling. No question.

I second the 3120, it has all the torque at a lower rpm. It will oil better if you get into a longer bar too.

Do you want me to PM you my address so you can send me that old 070?

Milling is not the 390s strong suit. 3120 all the way

Definitely 3120.

3120 is definitely a superior saw for milling.

Fuel consumption wise, depending on the fixed h jet size (probably 1.25 judging by your location) should be at around 75-80% of the 070. Mill at 25:1 oil ratio with these saws.

A left field suggestion for an alternative, can you get an echo cs-1201 where you are?

 

[Hammered]

3120 it is gang.
Thanks for the help spending the $.
Will update when I have it milling.

good solid work horses. Cut over a 1000 big slabs with mine, before overhaul was required.

What chain guage / size you going to use?

I'm open to suggestions iron.
Sounds like you have worked yours hard and dialed it in.
I'm guessing aussie woods are similar to what we have here.

For your ladder mill (like my logosol one) making planks / boards I found that a 24" bar running semi chisel .325 gave excellent speed and a quality finish. Trouble is finding a bar with a .325 tip. I had to swap a tip in from a smaller bar into it. This may not be an option for you.

Aussie woods are mostly on the same hardness, but they have a lower moisture content. So in a way even worse than what you are milling.

3120, cant go wrong. Go with large gauge chain.

That's what I find interesting. I can not be the only person who mills with .325?

In order of how much board feet is produced between sharpenings in my experience.

3/8, 404, .325

Not to mention how fast .325 cuts with a 9 tooth sprocket if your saw has the HP. Up to around 16/18" wide timber it is basically as fast as my 11hp gas/fuel bandsaw. Slows down abit once you get wider, but still cuts pretty quickly.

Just find this interesting, if I never got a logosol would never have tried .325, would have stuck with .404 :/

*edit* I am talking about milling lumber on my rail mill, not slabs on an alaskan. Be using .404 today to cut up some big burl slabs hopefully

Think ya got my meaning wrong here. Gauge as in .050", .058", .063" , I would not trust the narrow kerf stuff on a saw that size. Heard bad things about .043" and milling. Carry on!

Actually thought I had abit after I posted what is said is said though.

Being a husky bar, have .058 guage.

How do you say it? "No worries Mate".

Rode down and PU the 3120 off my neighbor.
Going to test drive it today.
.404 ripping chain. 15' angle
All I have is a 32" bar but with try a 24" this weekend with .325 chain.
Going at soft Spanish cedar mostly and should rip this up easily.
Few Mahogany trunks and is a bit harder.
Going to try a Guanacaste hardwood and see how is cuts as I have a ton sitting on site for grabs.

Shot of my other 600 cc Husqvarna with the 3120 tied to the back.

Nice pic right there gents! Me likey, all 3!

 

[Hammered]

32" bar sucked!
Rakes too low and near tore the ladder off the mounts.

Going to have to try a different chain and bar set up.

Learning curve and appreciate all the input and advice you guys are giving.

I have to say I don't like the fact I can't adjust the carb on this saw!

Wide open it needs a tweak.
Will buy a $22 filter for it and see if this brings up the top end power band.

 

[Iron.and.bark]

Not sure what spec your 3120 is. I had to work mine a little to improve the top end. The fixed carb flooded the saw at high rpm's

Could you check what colour the coil is? Green or black.

Also take the muffler screen off and look inside. Does it have a little "hole" / pipe inside?

Which colour of coil is the desirable one on these saws?
