I will be trying to build a small cabin after the snow melts using railroad ties, some of them creosote treated. My question is, if I were to make rabbet joints on them using something like the logosol loghouse moulder would the airborne creosote be much of a threat? I read that creosote logs are fairly safe after sitting for ten or more years, but I'm afraid that cutting through some two hundred ties would be dangerous for my lungs since creosote is carcinogenic. I also want to cut away one entire side of the tie to hopefully reveal a better surface for the inside of the cabin. Obviously this isn't the best wood to be working with, but it would be great to make something worthwhile out of these free materials.
