Blue stain

[bandmiller2]

Have any of you fellas that lube with water ever tried putting a fungicide in the water to control the blues.?? Do you think it would help.??I cant try it, being a petro lubber unless I could find an oil based fungicide. Frank C.

Never have heard of it before, can I ask, what blue you are talking about?

Blue stain on white pine when cut in warmer weather. Frank C.

[drobertson]

Oh,, only cut a dab of white pine, no blue to speak of, but I remember a very brilliant green mold that appeared like in one day,

[Chuck White]

I haven't tried it Frank, but it does sound feasible.

Probably wouldn't be awfully expensive, so it could be used in all sawing, not just those with blue stain.

Usually when I have blue stained logs, there are only a couple in the whole pile, so it wouldn't necessarily be used for "just" blue stained logs!

I would think that even coverage and volume would be lacking.

I don't think it will work.  Quick drying is the answer.  It is also impossible to remove the blue after it forms

I too think it is impossible to remove blue stain after it forms.  I've found that once the temps are there the blue stain sets in.

The production mill had a spray booth on the outfeed of the planer, at the speed the lumber was traveling thru it not much made it onto the board. The reason for the spay booth was to prevent the white mold from forming when the units with 13%mc were wraped and shipped to Arizona to sit in the hot sun like a peitree dish, to aid in keeping the white stuff off the wood we also changed from a full wrap to wrapping just the ends and top and added 4 hours to the kiln cycle.

Blue stain, not sure if it would help but should have enough flow with lube being sprayed on both sides of the saw making contact with both sides of the cut. When you turn up the flow it leaves the boards good and damp.

We get guys out here who will  pay extra for it if it is pretty. ;D

Just sayin'

Or cut it in the cool season.

[Magicman]

Remember that there are two very distinct forms of "blue" lumber.  One is from mildew and the other is from beetles that kill Pine.  Beetle kill is blue when it dies and the splotchy color goes completely through the log.

We got a lot of blue stained ponderosa pine after the big fires in the Santa Catalina Mtns. It was really pretty. I cut up a bunch for some people with a cabin up there. Spectacular and streaky. Sorry I didn't think to take a picture. Getting that tree down was exciting.

The active ingredient in some fungicidal products is a type of salt (Disodium octaborate tetrahydrate).  I would be concerned about corrosion on the mill if using this in the water lube.
