Hello all,
I need to attach two curves of red oak together at a central
crossover so as to form a 'X' shape. I've heard that iron
bolts stain oak due to its acidity or something like that.
Is this true? I built a futon frame before with a red oak
cross member and the dowel nuts I had in there seemed to
stain the oak, but I'm not sure if it was due to the nuts
or not. If they do stain, is it metal in general or just
iron (in the form of steel)? ie would i be able to avoid
staining with brass or zinc-plated bolts?
thanks,
andrew

Ferrous metal (iron, steel) will make black stains in oak because of
the tannin content of the oak. Exactly like the traditional black
stain made with tannin and iron filings.
Brass would be ok. Zinc plated would be ok if no pinholes in the zinc
plating. I would use brass.

If brass is strong enough, go with it. If not, go stainless. Ferrous metals
combine with tannic acids in oak to make for ugly black stains.

I've got some glulam beams in my house that were left too long in the rain
before the roof went on. I've got the black stain surrounding the steel
hardware joining the beams and the posts. Is there a good way to clean this
stain up? Sanding will take an awfully long time. Use a wood bleacher? Some
other product utilizing a chemical reaction that fades or does away with the
black color? TIA

Yes.

It only costs a modest amount to go first class.
Silicon bronze would be my choice.
A couple of years after installation, you will understand why bronze vs red
brass or heavens forbid, zinc plate or even galvanized.
Bronze is available from almost any good hardware store that is located
around boats or on the web from Jamestown Distributors in Rhode Island.

Try oxalic acid.
