Hi Bruce. Good to see you made it over here. I have some Wold Wheel spacers that may or may not work for this. If I can make them work easy enough, I would like to have triples. I have the iron cut for a double tool bar carrier about twice the size of the BluJet. It will carry the modified Bigham Bros tool bars. Maybe about the middle of feb or so before I get to welding it together. Sunday I will start welding on a 30' harrow for the back of the Blu Jet. The axles can be had at any seli trailer manufacturer. Actually they can be had at more places, but they usually have the best deals. Sometimes someone will order a trailer with specifics and then either loose funding or go banko and the manufacturer is left with the parts. Often they will wholesale or less price them to move them. They're quite affordable. I dont think I paid 500 for it.
