Dude, You did one bang up job on this ! it's slicker then a fresher cowpie after a rain storm. I have a few more projects to finish before even thinking about this build. One question, on the Komatsu Excavator could you add a claw or set of jaws I guess to " Pick Up " the ties? After looking at the picture I know I could bash a set GHQ jaws to fit your model,but man you are doing some great work !
