Have the chance to buy a quantity of railway sleepers... some kind of pine, maybe 10 ft by 12"x 6"----3000 x 300 x 150mm..they are replacing them with concrete throughout the rail system..
They are pretty good, totally impregnated with oil and of course grit and sand (and probably whatever drops out of the bottoms of trains and train's passengers' bottoms) but cutting up a couple with a chain saw, as initially I was thinking firewood, they are blunting the chain fast...
No wood yard is going to touch them, but the wood I have exposed is beautiful and really I'd like to get some useable planking out of them if I could, instead of just burning them.
Any ideas? I have a pretty powerful hand circular saw, but max depth of cut is only four inches and the De Walt blades that claim to be able to deal with the odd nail, or spanish worm as they call them here, are expensive experiments... Cleaving perhaps, ??
