What to put under my Sawmill.

[Iwawoodwork]

My log deck, I fabricated from what iron I had. The rails are 3" pipe top and bottom about 30" tall, about 3" taller than my saw rails. the 2 deck rails were trussed vertical with what was available in my scrap pile such as various size pipe, even old t posts, the two rail sections are 30" tall and 10' long and about 6' apart, again I welded horizontal braces between the 2 rails  top and bottom then x braced to stiffen so the deck would not collapse under load and it has not  even when loaded with 10 to 12 fir logs of 12-15'.
My deck is set about 24" away from the saw rails and I use a 36" section of pipe that slides inside my top rail with a V cut about 2" back from the outer end that fits over saw track when slid out to roll a log on, once the log in on then the pipe is slid back inside each rail. I had to weld a tab on the end/side of the extension pipe to keep it from sliding b to far back inside the rail pipe, was hard to retrieve. I built this deck to keep log loading machinery away from the mill and to be able to have more than one log at a time staged for sawing.  I also built the deck with the thought that I could load it on the saw frame when/if I moved the saw, my saw is portable.
