Thanks for the kind words guys !

I guess you could say its a little brother, but Dan it is from another family compared to your machine. Mine is stand a few hundred feet away scale compared to yours.LOL

Nathan I use photo's from the internet and I scale up brochers. As far as the track tension, I do use a spring in the track frames to keep the tension, also if a rock or any type of debree goes into the idelers the spring compensates. If you look at the 1-1 the pivot point is just ahead of the sprocket on the track frame. They have a system to keep the proper track tension as well...
