4x4 PTO Driven Timber Trailer BUILD Ep.5 - Steel Frame Fabrication

4x4 PTO driven timber trailer build continues with steel frame fabrication etc.. Also cutting flanges on the homemade CNC plasma cutter for the adapters that connect the BMW differential and homemade tandem axle chain housing. Starting to fabricate a steel trailer frame with dual rails. Using the old big green angle grinder again while cutting parts outside which brings back good memories from the times I started doing steel work. The tandem axle chain housing and trailer frame get mocked up and the hydraulic crane base plate finds its place on the tow bar. The shape of the tow bar will change in future episodes due to the routing of the propshaft and the height of the hitch on my homemade UTV I'm gonna use for towing this trailer around. The trailer is taking shape! Pretty good! Stay tuned for future episodes!

Trailer specs:
28x11-14" tires & 14" rims
1450mm/57" wide; length and height - unknown
tandem axles with homemade chain housings
BMW E39 530D differential with 2.81 gearing (identical to the UTV diffs)
hydraulic crane with a boom & grapple for easier log loading & handling
independent hydraulic power pack
radio controlled hydraulic winch on the boom
load capacity - 1-1,5 metric tonne

Stay tuned for the next episode & thanks for watching!
