          I'm impressed. Wow, what a nice job.

          I noticed the other aluminum trailer in your shop has the frame rails bent with the flanges on the outside. It seems like that would be easier to do and that it would make it easier to fit up the joints. Why did you bend these the other way?

          I assume the welding was done with a spool gun. What brand/model did you use?

          I'd like to see some close-ups of the welds. Probably give me something to shoot for the next time I get an aluminum project.

            Excellent work. Aluminum is my favorite material.

              whistle ... bet that alum wasn't cheap.

              Really nice job.

                Winchman, the Float On brand trailer is of the typical AA I beam construction and has the single bend just forward of the axel. I wanted the smooth side look that channel offers. The hardest bends was the re-curve for the coupler attachment. Miller Spool Gun 3035. It does pretty good but gets all squirrely when the wire spool gets down to 1/8 full. Best to just go with a new roll rather than trying to use the rest. That caused some of the welds to look crappy.

                  Pardon my ignorance - what is the function of the pivot at the trailer tongue? Is it only to shorten the trailer tongue when stored?

                    Looks factory, well made, I had to repair one a while back, they forgot drain holes so it was fetching the sea home every trip.

                      Very nicely done! I love aluminum as well.

                      While camping a couple summers ago I saw a shop/home made all stainless trailer. Had to take a few pics. It just looked like allot of money.




                      The only thing I would personally worry about on your trailer is the connection for the swing away tongue. If that connection where the pins go threw is also aluminum it may either stress or fatigue crack over time, or wallow out over time till the holes get close to the edge and then crack/break out.

                        Yep, it shortens it by 2 feet when folded.

                        The coupler is a store bought and the whole thing is steel (all 35 lbs). However, considering the same concerns as you, I've incorporated a SS fastener tear out prevention strap on the lower portion where the coupler is attached to the aluminum frames. That's where lots of tension cycles would be occurring. Although it will probably be just fine without it, I wanted to have a safety feature in place.
                        Thanks for the feedback.

                          Wow! That thing is awesome! I have had that thought more than once... but cost and weight both kill that idea real quick for me. Although, he did not spend nearly as much as I did on fasteners
                          Thanks for sharing that pic!
