Oak n ferrous metals

[OneWithWood]

I got another reminder of why you should not place green oak boards in close proximity to steel.   

I milled up a red oak log for a video the other day and just laid the boards off on a pair of gravity rollers I use to help transport heavy slabs to the kiln carts.  When I moved them a day later there was a nice blue stain where the wood contacted the rollers.

A quick look around the internet seems to inidcate all aluminum gravity rollers are rare.

If I put a good thick coat of rustoleum on the rollers I have do you think I can use them with oak?

[Dan_Shade]

I would think so.  Another option would be to send them out to have them chromed.  Not sure what that would cost.

[DanG]

If you can remove the rollers from their frame, you might could make some sleeves for them from some poly pipe.  That's the cheapest and most durable solution I can think of.

Or turn out some wood rollers. 

-- or try the rustoleum first.

[DanG]

I don't think the paint would hold up very long.  Of course, the cheapest option is to just not let the lumber stay on there, in the first place.

Or take them and have a LineX or Rhino-liner(truck bed liner) sprayed on them.
We used the stuff in the shop for wear coatings in mass finishing machines. (IE industrial cement mixers)

I had the same thing happen this spring as I was sawing up a white oak log.  I stacked the boards on the tractor's forks as I was sawing them, and as soon as I was finished, I hauled them to the drying shed to stack.  They were already stained, even though it had only been a couple hours.  Now I make sure to put dry boards onto the forks first when stacking oak on the tractor.

 Powder coat 'em.

Had that happen the other day, in minutes. guess that is why they want to saw over size and plane off.

I learn something new here everyday.

most of the oak stain from short term iron contact will readily plane out.  It does not run throught the wood like the stain from internal tramp metal.

Even the short period that a cant sits on iron bunks will cause stain.  Stainless covers were the best thing that Woodmizer provided.  Usually this stain is not deep.

I left some Oak on the back of my work truck for a couple of months (or more) and the diamond design was so deep in the oak, it wouldn't plane out.  If the contact is minimal, I think the stain will be too.

I hit nails when sawing some oak the other day.  The next day, the line of sawdust,on the ground, beside the mill, had a black area where the nails were located.  That was from the little slivers of nail that mixed with the sawdust at that one point.  You could tell exactly where the nails were on the mill.  It doesn't take much, but it has to remain in contact long enough to make Iron Tannate.

Thanks for all the suggestions.

It is good to see I am not alone and that this discussion has been useful for others.

If you can't be a good example at least you can be an example 

That's an old saying I just made up . . .

That's pretty old, as far as sayings go.  Most of mine don't make it nearly that long!

[woodmills1]

so much rain here that the dripage from my iron truck bodies is leaking on to the aluminum tool boxes under the bed and making a weird looking stain.

[Captain]

This thread really brought a smile to my face.  Tom said he was sawing the other day 

[Tom]

Yep! A log a day helps keep the mullygrumps away.  A neighbor kept bringing logs and I had to do something or get covered up. What I need is help, some cooler temps.... and just a log or two a day. 

[Cedarman]

Not good to sharpen your chainsaw on fresh cut oak boards either.  Or any lumber for that matter.
