My first trailer, first time with hydraulics. I had everything but the but the hoses. It actually works 
Thanks for the replies, the axle is from a mobile home, I cut about 2' out and put it back together. The hitch is an old receiver on a 7''x7''x 3/8 angle, but still flexes a little. The plumbing went well for an educated guess. I still have some finish work to do, clean up the hoses, some welding, and some paint.
