Update time! So my buddy the mechanic was nice enough to mount my new tires on the junkyard rims I acquired. When I picked them up I was shocked! They were WIDE!!!! So wide, in fact, that the backspacing became effectively too much for the trailer to take. The tires when bolted up rub against the sheetmetal. This will not do at all..... So it looks like I'm going to have to get some spacers!
Here are the tires mocked up on the trailer. You can see how they sit too far inboard:
To solve this issue for now, I found a set of 1.25" spacers on Ebay for $50 shipped. Since someday I want to change out the axle to one with a 5 on 5.5" pattern, this should work for the time being.
I was also able to make some serious progress on the spring assemblies. Having finally decided to keep the stock length leaf springs, I pushed forward to remove the bolts securing the spring hangers and leaf spring assembly. This was not an easy task with most of the nuts being unrecognizable rust colored blobs!!!! Luckily, judicious use of PB blaster and an air ratchet finally knocked MOST of the bolts free. I still have two resilient hangers that are going to need heat or a grinder before this ordeal is over with
After what seemed like hours of clanging and banging, I finally emerged with a complete axle and leaf spring assembly. It practically shouted, "Clean me!!!"
With that in mind, I set up my newest toy:
Harbor Fright was having a sale on everything so I was able to get this little beauty for $50 shipped to my door! It took a lot of fiddling and a return trip to TSC for some finer sand, but after tweaking it I was able to get great results even with my smallish 21gallon compressor (5.6cfm).
The spray pattern was pretty small and the fine media made for a slow rust removal process. I'm still trying to decide if I'm going to hire out the tub sandblasting or do it myself. I'll cross that road when I get to it!
Next on the list is to replace the Ubolts and leaf spring bushings, then mount the assembly to the new frame. It will be really nice to have a rolling chasis to work with. That frame is getting heavy
