I would use water, and for green wood it doesn't take much...
I would NOT use oil/diesel for the lube, think about it tree's are full of water, why are you adding oils? It takes very little water to lube the blade, so don't set it up to use more than a drip when sawing.
Lots of folks think the water is used to cool the band, but it's really there as a lube...

I'm learning as I go and I have been watching/reading info from the guys who build the saws. I think Norwood said diesel is what they use.
Not knowing any different I thought, ok.
I already have some of that on hand.
I did read posts here, and elsewhere, that offered all kind of opinion on lubes, but figured diesel and bar oil made sense. My logic was bar oil is sticky so stays there a bit longer
and diesel is actually a good lube (I've put some drops on 5th wheels when grease is not handy).
Soapy water makes sense too. I didn't figure water alone would keep sap from building up.
Yep, and a lube does keep it cooler.. I mix some Pinesol in my water, wards off all the sap in these SYP logs.
I'll try water (I'd have to go find pinesol

) first I guess and see how I fair out.
I wonder how Murphy's Soap would work? I have an ancient bottle of that somewhere
but damned if I know why.

I don't have any kind of drip system set up yet.
Will a squirt bottle work well on a temporary basis?
If not much is needed, maybe a squirt before each pass?
I really appreciate the coaching too. Thanks all.
Any advice on what I could use as a "valve" for a drip system? I figure a camping type 5 gallon water bottle and any kind of small hose,
but no idea what I could use as a valve yet. Something would eventually come to me or fall in my lap, but I'm open to proven ideas.
