    When you run your replacement hat channel, (the 1" square tubing) one thing that comes to my mind to consider. When you drill for the mounting hardware, over bore the hole, and sleeve with section of pipe. This would add to the overall strength of the frame. Do you have to, no. Your 1" square is plenty strong, but the pipe will prevent water intrusion into your frame work. When I replaced the hat channel on the M38A1, the original hat channel was strengthened with pieces of white oak. Being that the heeps were never designed to last forever, that was a cheap and easy way to reduce costs. The down side, water soaked into the wood, and dissolved the hat channel from the inside out. Long story short, I didn't use any non ferrous material when fabricating the channel. I did cut some steel pipe spacers to prevent the hardware from deforming the channel when tightening. The channel received several coats of primer and rust preventative before being welded into place. Another quick tip for when you fuse the floor sheet metal to the sub frame, use weld through primer. The stuff works really well, in my opinion.

    Thanks for the tip, didn't think about using a piece of pipe as an insert to keep it water tight...much appreciated. We will see what happens haven't quite decided on how to go about building the boxed frame yet but seems to be the best way to go about it. Trying to decide to go with 14 gauge or 16 gauge sheet metal.

    18 gauge is the original thickness, but is hard to find in quantity. I would be comfortable to use 16 gauge because it would form better for the bends needed, but could see where you would want the 14. 14 Gauge will last longer, and offer more structural fortitude.

    I have been working with a lot of 14 gauge lately building work benches, hangar doors and such. Itís easy to weld but hard to shape if it needs to be fitted by bending.
