Thanks Ari! I spent the whole day working on this(almost 9 hours) but I think I got a lot accomplished too! The suspension is nearly finished now so I can weld the two main components together and start making a deck.
Here's a short video of the walking beams and axles after welding them to the frame...

I started out by making the walking beams out of some 1 1/2x1/2 flat bar.
I then lathed and milled some pieces for the axles. The axles should be held to the bushings with U bolts but this trailer is meant to work to scale not so much be detailed.
Once everything fit together I decided that it needed more flex so I re-drilled the bushings to a larger size and added some rubber hose.
I then welded the pieces to the frame.
Lastly I welded some lugs to the loading ramps.
Thanks for lookin!
