The original trailer I received when I purchased my first mill, was an axel about 4' wide with two 14" rims on independent spindles. There was a wooden block attached to the axel and you C clamped the track to the wood. At the opposite end for offberring was a 2" ball trailerhitch attachment to hook to a vehicle. As to the endstands and crossfeed, you simple put them in place when you arrived at your sawing sight. You then removed the track and carrage from the transport axel by pushing the carrage all the way to one end and lifting the track off of the axel. I hope this makes some sense. I will try and speak with Dawn, tomorrow about posting some pictures of the process and the axel I am speaking about.
