Default Another Trailer Build

Or what to do with the old boat trailer.

Long story short, I had a bass/ski boat that was derelict in it’s duty of being a boat, so I sold the motor and hauled the boat to the dump and came home with an empty trailer. Being a typical boat trailer, the construction was channel iron rails that were bent inwards towards the front to form the tongue and channel cross members that were Vee’d. After figuring out how long to make it to haul my buggy with the correct tongue weight and what was left over, the tongue was cut off, the cross members cutout and the rails straightened. The width was spot on so the axle did not need any work. An O/A torch was the predominant tool, as well as liberal use of a grinder and judicious use of a press.

There was a bit of 3x3x3/16 tube floating around, so four pieces were cut and coped for new cross members. The rails and tubes were then tacked up into a rectangle to form the basic outline. The Vee was removed from the existing cross members and short pieces of a rem channel brought them to the correct length. The cross members are coped halfway so a 2x6 or 2x8 will lay flush to the top of the rails.

The angle iron across the tongue was cut and mitered for it’s new role and the welds where the channel met the tube tongue were cutout to allow the channel to hinge outwards. There are definitely some gaps to fill, but the copper plate laying there will provide the backing.
A possum belly between the tire rails is a possibility, or the whole thing may get decked in wood.

The buggy in the background will finally get a ride. More to come as progress is made.

Trailer looks great, should be plenty of room on it to haul extra stuff, gas cans tool box ect.
The buggy is just too much fun , I been playing in the sand since early 70's. Mostly just sand dunes, I still have my sand rail but haven't had it out for about 5 years, all the regulations and crazys have taken most of the fun out of it, around here anyway.
Have fun , stay safe,
Rich

That gap is ridiculous. Plate it after filling it, and it'll be ok (sorta). It's a bitch to repurpose stuff, sometimes better to fit up a new piece. Here at the compound, that channel would go on the scrap rack.

If you can fill it , it is not a gap. We are not watchmakers.

Just knock the flux off a rod jam it in the gap and weld it up that was good enough for the liberty ships i WW II it will work for that trailer The copper underneath will make it fast freeze.

I guess a guy could just fill it. But then you gotta give up your right to gripe about the stuff made outta Chinesium

Put all that filler in there, and she's gonna shrink like a cheap pair of pants.

If it does shrink, it's not going anywhere. But now that you mention it, the sides of the tongue are tacked in place and it would not take too much to cut the hinge weld loose and shorten the channels a wee bit while correcting the angle of the cut. Something to ponder. It is definitely not going in the scrap bin.

Copper has been around a long time for backing up welds. A good friend of mine years past made a good living welding vertical seams in refinery vessels using copper shoes to contain the weld puddle. One alternative is to use carbon rods as a backup, but that puts excess carbon in the weld right at the root, so that's a no-go.

Nuf summed up the situation. I don't see a NASA logo on the side of this build nor do I see a Reactor Containment Vessel. Would it be nice if the fit up was better. Well yea but it will still work as is. I watched all manner of horrors go through our fab shop all the time. It all depended on the specs called for in the contract. Some shit was as close to immaculate as humanly possible and they paid dearly for it and other jobs came under the heading of Get-R-Done no scraping of weld pimples or even grinding off tacks from fit up. But, you know what it all worked none of it came back cause the customers got what they paid for.

Looking at that pic of the angles butting up to the center member. Easy fix take your torch and trim about 3/16" off that front vertical leg to close that gap up. Trim the flat leg as needed when you draw it in.
