Hey Chuck, normally I would agree with you..... but I have the trip home with Fuggly permanently etched in my memory. There was a light rain and all I can remember is looking in the rear view at 40 MPH thinking it looked like I was towing a grease pig, bungee corded to a trailer made out of wet noodles. It scared the hell out of me on side streets, much less the highway! I was a little surprised how flimsy the trailer was after the tongue modifications. It would probably be ok without boxing the frame, but for $70 worth of steel and some time it should be rock solid. I spent a lot of time with Miss Morgans trailer and have been really happy I did after a several 1000 miles. Never got in trouble for over building other than the cost, lol!
Pat I think I understand your question, but might be off. I am boxing some of the cross members, but just the ones that the tongue attaches too. The rest I am leaving as c-channel. I had some work and chores this morning but still had some time on the trailer. I would have gotten a lot more done if I hadn't watched football for 4 hours lol!
I did finish up cutting and fitting all the steel I can until its welded up tonight. I have a bunch more grinding to do tomorrow, then a lot of welding.
Here's a few pics from tonight. This one shows the connection between the frame rails and the rear cross member. Its not a very rigid connection and flexs a lot!
This is how the new boxing plate will be tied in and welded, much stiffer.
It took a little heat to bend the corner, but it worked out nicely
This is the front cross-member that the tongue attaches too. If you look closely you will see a relief cut in the center of the plate. That is because the old tongue actually bent the cross member and it isn't strait anymore. I also found fractures in some of the welds up front, disaster waiting to happen.
This is the cross member behind the first, I extended the new tongue to attach to it to shorten the lever arm of the tongue. I kind of wished it I had swapped it out for a 4" member, but I think it will be fine now that it is boxed.
This is the filler I am putting in to stiffen up the joint in the first pic.
