While over at a friends (fellow woodworker) garage shop, I mentioned
that he hasn'e been doing enough work in the shop. His older Unisaw had
some very light signs of rust on the table. He told me that if you
leave some pressure treated wood on the top for a day or so, You will
have some rust. I'm not sure when he waxed it last. Just thouht the
the rust from pressure treated wood, might interest some of you who use
it. Something to remember.

Pressure treated wood, especially the newer stuff is very corrosive. My
daughter and her husband are currently suing a builder who totally screwed
up their home construction. One of the many problems was the use of
untreated fasteners to attach the planks to the framework. When a crew, who
is trying to correct the problems, started removing the 1 to 1-1/2 year old,
untreated screws many broke off and all were very corroded.

It is well documented by treated timber manufacturers that coated fasteners
should be used with treated timbers. Steel frame member manufactures also
document that raw treated timbers should no be fastened to zincalume
products. Some untreated hardwoods should also only use coated fasteners as
they also react with normal fasteners.

PT wood is loaded with moisture, Just about any wood that is not dried to
the normal furniture making 4-8% moisture content will rust a TS top. I
have seen cedar pickets cause a top to rust also.

I've had rust on both my saw top and saw blade when cutting
construction dimensional lumber. Moisture can vary. Cedar fencing is
really damp...
