The Trestle wood "salty fir" is generally reclaimed from the salt lake area. The timbers are saturated with salt, hasnt been exposed to the air, and very heavy. My experience has been on several projects in Colorado using this wood. Several things to consider when using trestlewood........... You will eat up planer blades like there is no tomorrow. Same for router bits and such. Very hard on the tools. Also once the timber is planed, say you plane to 12" stock. Come back the next day the timber will be at 12 1/4" to 12 1/2" . I assume this is due to the air and salt contents.Also we oiled all the timbers prior to delivery, and yet every morning when the dew set on the timber, salt would seep out and run down the timbers. The smell is very distinct when working with these, sort of like cat piss. Some of our guys were even sick after working them. These are some of the drawbacks we experienced, but the final projects were amazing. Coloring was very unique from the extreme reds to black. Just an absolute gorgeous timber if you can get past the fabrication end of it.
