Subfloor Secured

Mr. C took a day off to spend quality time with me and Money Pit. The weather was a little iffy and we don't want our new floor wet. We headed to the store to purchase plumbing supplies. Up and down the isle. Try to fit this to that. They only have male threaded in this size and we need female, etc. Finally we have all (or so we hope) pieces of the puzzle. Back home and now it is raining. Up went the pop-up canopy so we could get to work on completing the C channel. By the time we finished the front, it was sunny. Take off the tarps and complete the back side. Done!

Onto the elevator bolts. Mr. C said we wouldn't use very many. We used 31 which I thought was a lot. He assures me it isn't. He used a forstner bit to make the indentation in the floor and then a regular drill bit to finish the task. I held down the bolts from above while he tightened from below.

Once completed, we did another flip so bottom side up. Rain in the forecast so, we wanted to make sure it was covered well. We used the original flooring on top of the frame (bottom side) and then covered with a big tarp, bungees and 2x4s. And the thunder started. No rain last night, but it is coming down tonight.

I've been watching your progress, very nice work. I'm also restoring a GT but it's a 71. check out the link below

Thanks for all your answers to our questions. I really appreciate it. I now understand how Mr. C got the C channel around the curves. Makes sense. I saw aluminum stack window frames being mandrel bent at the Jackson Center factory a couple of years ago. They made bending aluminum around corners look easy.

I was glad to hear MDO was suitable for your subfloor material. I knew it was used in cabinet making as I understand it is a rather strong and stable material. But I didn't know about its weather resistance. I have some of it in my old Trade Wind for cabinet doors and shelves. I'm hoping it will hold up to the temp and moisture variations it will see inside the Airstream.

I also used a biscuit joiner on the subfloor of my 65 sovereign. It was a little tough but in the long run I believe it will keep the floor from buckling. Love your progress!!

Before the Belly Pan

We have been working away for the past several days. Slow progress. Mr. C got the gray tanks installed and plumbed together. We then started the process of insulating and wiring. All of the foam is in, but we need to carve out around the corners before installing the belly pan.

Friday night we had our 1st temps down in the 30s. I covered all of the veggies and now I am wondering why. Maybe we will get a few more tomatoes. We know the days are numbered before snow. Hopefully we can get the shell on first.

We did a run to Coates RV in Hugo this evening to pick up a valve. The man at the register indicated another person restoring an Airstream was in/called looking for a valve today. Hmmm, who are you?

I wonder how Mr. C mounted the gray water tanks. Did he make straps, clamps or something else. The tanks are resting on Styrofoam and a steel pan on my 86. There is no mechanical straps or clamps. Not the best in my opinion, but it has worked for 28 years.

It will be fun to see how you build the tank drain plumbing combining the black tank and gray tank with two valve and one outlet. Adding waste water capacity in these old Airstreams is a challenge.

What is on top of the plywood that looks like thick craft paper?

David - the gray tanks are wedged into the bay with styrofoam. Mr. C will be using fiberglass panels to hold the tanks in place. They will be easy to drop if we need to access the tanks. We will not have a black tank because we will be using a composting toilet. The composting toilet seemed like a good fit for our lifestyle as well as simplifying the plumbing requirements and location of the toilet itself.

Perry - the craft paper look is the exterior coating on the MDO plywood, also known as sign board. "Medium density overlay (MDO) is an exterior-type plywood. It is overlaid (heat-fused) with a smooth sheet of resin on one or both surfaces. These surfaces can be painted and function as a water-resistant coating." We used sheets that were coated on both surfaces.

Okay, a composting toilet eliminates the need for a lot of plumbing. I hope they work better than my compost pile in the garden. I'm a bit skeptical.

A 25 gallon gray tank will weigh about 200 lbs when full. So it takes some support to keep the thing under the trailer and not on the highway. Having access to them in case of problems would be handier than taking the belly pan down.

You folks are making great progress.

David

The Last of the Floor Insulation and the Belly Pan

Mr. C has been plugging away at the underneath of the trailer. We completed the insulation and he formed the shape with an orbital disk sander. He then started to add aluminum from the side rails wrapped around the bottom of the trailer and attached to the C channel. The area between the side rails is being covered with fiberglass panels.

Very nice work on the rear corner pieces. They are difficult to make. It appears Mr. C fabricated an attachment point on the frame rail so he could rivet the rear corner pieces tight. Ref pictures 3 and 4 above. My 66 Trade Wind did not have anything to attach the corner pieces to. They just flop in the breeze.

It won't be long before you marry the shell to the new frame.

David - he attached an aluminum piece to the frame rail with VHB (very high bond) tape by 3M. This allowed attachment of the belly pan with rivets so it would not flap. We buttoned up the belly pan today. YEAH! Discussing what else we need to do on the bottom side - gas line, coat the inside of the wheel wells, and a few tweaks to the plumbing.

It is our plan to replace the exterior sheet of aluminum under the front window before we pair-up the frame and the shell. There are two other panels to be replaced, but we will do those after the pair-up. Hopefully before the weather turns.

Interesting application of the VHB tape. I've got to try that stuff someday. Adhesives are as good as welds anymore. There are a lot of modern adhesives used in auto manufacturing.

We're going to have a long, glorious fall season. You have lots of time, don't worry. You folks sure have come a long way since you bought the 62 GT home the end of July. It's going to be one very neat vintage Airstream!
