Dremel, from what I understand from listening to the VAP and threads I have read, Olympic rivets are not structural. I know that a lot of people replace windows and minor patches with Olympics, but not end caps and structural panels. I think once you get into the drilling out of existing rivets and bucking in new, you may decide to remove the Olympics. Whatever you think. You’re well on your way. A lot of fun. Good luck, Bubba.

Thanks for the advise.

I plan to get the solid rivet tools. With a bit a practice, I'll decide if I want to replace the Olympics. Now is the right time to do so.

a little progress

Since the last post, I have been figuring out how to get out the old sub floor.

I first pulled up the 1/8 board that was nailed to the subfloor. Used a crowbar and muscle.

Then cut the heads off the bolts.

I found that an osculating tool with a metal cutting blade works great to get under the C Channel and the other bolts.
However, I went through 2 blades and they are expensive.
Also used a cut off wheel in my angle grinder.

used a circular saw and sawsall to cut out sections.

I have the first 8 foot or so out. Looks like a Squirrel or Mice were living here and had their nut storage.
Pulled out the insulation and vacuumed.
The Steel frame looks to be in good shape.
I will wire brush it and then prep and paint with POR15

I do not know if this is how all 69 airstreams are, but my belly pan is one big flat piece. It rivets to the pieces that curve up to the side skin.

So , I can drop the bottom part so that I will be able to get to the bottom of bolts, and later insulate.

I am going to try to do this Floor replacement in sections.

Drop the belly pan in the front and rear of the axles.
Make floor pattern off what is left of the original floor onto 5mm luan type board. Then test fit it.
I will then use that as a pattern for the 5/8 or 3/4
POR15 it
Then put in the front 8 ft
Repeat on the rear section
Then Middle section.

Along the way, deciding on tanks and other stuff that goes in the floor.

I am trying to keep moving along, usually get about 2 or 3 evenings and 1 weekend day to work on it.

Received my buck rivet kit from VTS.
Will find some time to practice on some scrap.
They were out of the Olympics, but will get some of those to use in proper areas when they get more.

While you're at it...

Something you may want to consider while you have the front subfloor out is to weld a couple of cross braces across where the tongue enters the body of the frame. Seemed like quite a span without any support.
I did so on mine and it made a huge difference in terms of support there.
Below is a progress picture of what I'm talking about...
I welded the angle iron to the long span for additional support.

1" square tube fit just right and happened to be what I had laying around

I used bolt cutters to get the bolts in the C-channel out. Horned well since my floor was such a rotted mess

belly down in front

Thanks for the idea's. That is a big space in the front.

Last Monday I got under the AS, and drilled out the rivets for the flat part of the belly. Went all the way back to the wheels.

This way I will be able to put the nuts of the bolts for the floor.

Layed some thin plywood on the ground to protect the skin from rocks, etc if I need to lay on it when painting or putting the nuts on.

Anyways, while doing this, I got cra* dumped on me that was still in the belly sides. Not much, but enough that the next few days, were spent fighting off what feels like a head cold. Probably breathed in a bunch of it.
Should have had on my respirator.
Just now getting over it. So, if that was the cause, then I wasted 4 days recouping.

more progress

Slow but sure,

Cleaned up the frame with a wire cup on my grinder.

next will be the POR15, but instead decided to make a template for the first piece of floor.

Used a piece of plywood to make my story stick. ( never used that term for this procedure, in construction, a story stick is something else )

I used a square as my stick, since it was thin, I could push it right up to the outer skin. This way, I do not have to add on for the c channel thickness.

Transferred the story to a piece of 5mm luan. And it when right in.

I am not sure when I will get to apply the POR, It states that it should be at least 50 degrees. And it is not going to get there for a while.
Might be able to run the kerosene heater and do it at the warmest part of the day. Wont be till after Thanksgiving anyways.

It was snowing out when I sprayed the POR 15 on mine, no problems. Bought a cheap Harbor Fright touch up gun and just threw it away when done. All done outside in the gravel and rocks.

Still working

I haven't given up yet.....ha

Some other projects have slowed me down, but when I am not in the trailer, I am still researching.

POR15ed the front rails,

played around in the back and pulled up part of the floor by my hands.

Purchased AC plywood. Had to go to Lexington to get it (1hr away) but this stuff is much better than the wood at the local Lowes.

Two months since the last post.
I have been working on it. Any time I'm not, I planning ahead in my head and on paper.

Cut out the front piece of floor using the template I made earlier.
I gave it 3 coats of Poly and installed it.

I have not Polyed this piece yet.

Dropped the rest of the belly pan. Decided to pull it out entirely.
Cut it in half at the axles to pull out. Ended up cutting it around the axles.
Pretty much deciding that I will put in a new one when the time comes.

It is now officially fully gutted.

The frame has been wire brushed and painted with POR15

I have cut the template for the rear piece of floor. But have not test fitted it yet.

I have 2 new grey tanks to go in the belly pan. 15 gallons each if I remember right. They will be plumbed together.

I have my new fresh water tank waiting for the near future. It will be under the sofa or gaucho or whatever I put up front.

New axles have been ordered.

The frame only needs a few spots of new metal.
I few of the "straps" that connect the outriggers. The piece that the banana wraps rivet to.

Also a few spots around the steps need patched.

Should be good for at least another 48 years. Then after that, I will not care.
