Frame repair and POR 15 on rotating support - 1963 Globetrotter

[Sychedelia]

I am have started work on the frame of my GS project. Complete axle replacement, repair of the frame and outriggers, and POR 15 rust treatment is planned. I have seen some threads in the past where people have suspended or mounted the frame in a way that it can be spun on it's longitudinal axis so welding/grinding/and coating can be done without working from underneath on a creeper. I have not searched but not found a thread here describing it or how to do it. I think it will really help the frame repair, and may also help with work on the subfloor and to flip the trailer for belly pan work. Any ideas on how people have done this in the past? Take a look at my trailer. I was left with a jury rigged rear bumper with a generator mount and spare tire mount welded on. It is solid with good welds. It will probably go with the renovation, but I thought the wheel mount and an old axle could be incorporated into some type of rig. Does anyone have a different idea?

Hi, If you search for "gantry" in site:Airstream Trailer & Motorhome Owners Community on google you should find a ton of useful info including a PDF showing a typical gantry design. Hope that helps.

Thanks for the reply. I have my gantry and hoists, I did not think to use the gantry to suspend the trailer.

Check out the following thread, starting at post #9.

I used my gantry frames to support each end of the frame. Used a single hoist at the A-frame end, and a loop of webbing inside the "A" to allow 180 degrees of rotation. I used two hoists at the rear, one at each corner of the frame, but mounted fairly close to center on the gantry. This allowed me to raise one corner while lowering the other until the frame was perpendicular to the ground.

Good luck!

Exactly what I was looking for. Simple and easy. Picked up a 3rd hoist at Harbor Freight today.

Sorry typo, I did search, before asking

Those rear appendages need to go, the frame was never designed to handle that weight that far back. I would look at trying to beef things up a bit since you have it all exposed, if you arent a welder, spend a few hundred and have somebody add some steel, especially in the back.
