It's finished T!

Just haven't posted all of that yet

I know, I'm a bad man...

I've been down farmside, beating cedar trees into submission for a couple days. Well that and cutting firewood, bush hogging, putting up tree stands (Other menses actually) and generally havin' a purdy gud time!

So, since I didn't do any work on the camper, I can still post pics, because I am daze ahead of what I'm postin'

Next I started adding fittings to the semi completed tank. The large fittings are two drain plugs that will be glued into the bottom of the structure (Obviously). The brass fittings are for the 1/2" pex lines that will feed water to an on demand water pump. and the gray nipple thing is the fill hose attachment bung

Just before drilling holes I went around and added material over areas I thought might need some strengthening

Flyin6 · « **Reply #104 on:** October 13, 2019, 10:17:58 PM »

Here's the core sample so to speak and the holes in the tank bottom

You can see there is a substantial overlayment of fiberglass

I marked the hex on the bushing, then chiseled out to fit it to the proper depth into the plywood

Flyin6 · « **Reply #106 on:** October 13, 2019, 10:20:51 PM »

Water fill pipe nipple going in the lid

Flyin6 · « **Reply #107 on:** October 13, 2019, 10:21:39 PM »

And the 1/2" PEX pickup and supply pipe

Flyin6 · « **Reply #108 on:** October 13, 2019, 10:23:52 PM »

Once I worked the resin around everything, I taped the bushing in from the bottom to contain the liquid resin, then poured the cavity full. I topped that with fiberglass cloth and a little more resin

Flyin6 · « **Reply #109 on:** October 13, 2019, 10:24:58 PM »

The outside of the tank lid about to get its "primer" coat of resin

I feel the full tube is a bit small, that’s a massive amount of tank to fill, most RVs use 1 inch I think

Next I went after suspicious areas and did some reinforcing

Flyin6 · « **Reply #116 on:** October 15, 2019, 09:41:53 AM »

Then after quite a bit of sanding and smoothing with 36 and 80 grit, I laid in some bondo over some spots and areas to provide a good seal

Flyin6 · « **Reply #117 on:** October 15, 2019, 09:44:03 AM »

...Nasty, gooey stuff, I know...

That hardened pretty quickly and was also smoothed out some. I didn't really need a super smooth or regular surface because of the nature of the final coat that was going on next.

Flyin6 · « **Reply #118 on:** October 15, 2019, 09:45:25 AM »

Here, the underside of the lid is scuffed off and smoothed in preparation for the top coat

Flyin6 · « **Reply #119 on:** October 15, 2019, 09:49:27 AM »

And here is what I chose to finish the tank.

After a conversation with Salt-Lake Dave (SLD or just "Slowed" for short) where he had suggested I find a food grade epoxy, my quest landed me at a Sherwin-Williams commercial paint supply.

This stuff is real live epoxy, the old part "A" and "B" stuff that hardens up like woodpecker beaks and is as thick as week old whale snot!

Flyin6 · « **Reply #120 on:** October 15, 2019, 09:52:48 AM »

I specified I needed a food grade coating for use on the insides of water tanks and the gentleman handed me that stuff. It was low to no VOC, which I understood to be one of the earmarks of food grade stuff.

I laid it out on the lid at first to get the feel for the stuff. It is thicker in consistency than paint so you have to work it in to level it and I did not see many instances where it would drip off the edge

Flyin6 · « **Reply #121 on:** October 15, 2019, 09:53:43 AM »

Then I brushed/slopped it onto the actual tank innards:

Flyin6 · « **Reply #122 on:** October 15, 2019, 09:54:41 AM »

This is only the first coat! It looks like a porcelain bath tub when fully coated, and man, it was really COATED!

Bigdave_185 · « **Reply #123 on:** October 15, 2019, 09:56:20 AM »

You also can sand and recoat in short fashion. The cure time or re-cost time is hours after cure. You could sand and re apply and lay it off flat with a foam roller for a smoother finish.

The whole business got a second coat, taking out another couple sacrificial paint brushes. Coat number two went on + 24 hours and also allowed to set up over that night. The following day, it was time to fit the lid

Flyin6 · « **Reply #125 on:** October 15, 2019, 09:58:59 AM »

Which is setting up here with its final coat

Flyin6 · « **Reply #126 on:** October 15, 2019, 10:01:15 AM »

But just before installing that, I noticed a couple small pin hole looking openings. I am pretty sure nothing survived all those coatings, but none the less, I went over them with more bondo just to be sure

Yea, copy

But

Too late, it's already done, as you will read about shortly...

Flyin6 · « **Reply #128 on:** October 15, 2019, 10:03:33 AM »

And so, yea, It got yet another coat of the slimy stuff

Flyin6 · « **Reply #129 on:** October 15, 2019, 10:06:04 AM »

You don't measure this stuff in "mills" of thickness, but in "inches" :-0

Ah, what the hay, I laid it on the top as well, I mean why not?

Oh and by the way, that stuff retails at $186 per gallon!!!!! I used a discount and paid $62 a gallon which was six times better than prudy darn gud!

Flyin6 · « **Reply #130 on:** October 15, 2019, 10:07:27 AM »

And BTW, I have been walking all over the top of that lid which is currently already installed while assembling other things above it. I don't think it is even showing scratches!

Sounds like you might want to consider glassing and putting that epoxy over the entire exterior!

I am definitely considering doing exactly that
In another configuration it is used to cover surfaces on watercraft and protect against a salt water environment

Nice stuff but pricey!

Bigdave_185 · « **Reply #134 on:** October 15, 2019, 05:04:56 PM »

The stuff you have does not like UV light, it will dry and turn chaulky. Unless my knowledge is old. Exterior I would suggest other stuff
What are you using to seal the lid on top?? Rubber gasket, silicone?

I do, but I have been curious what he has in mind and now used to seal the two, from the get go of the water tank build. If I get these hats finished up this morning I’ll probably get the truck back on the road... ie re install transmission and corresponding pieces.

wyorunner · « **Reply #142 on:** October 17, 2019, 12:01:43 AM »

Yep, I got to it alright, and fought my machine all day, just to get 8 hats done. I asked my wife today if she ever gets tired of wasting time, because that’s all this machine made me feel like I was doing today.

Made this as a test, not for a customer. And it worked flawlessly. Customer hats, just about brought out the sledge to solve the frustration with this machine.

If I use this on the exterior, it will be only to seal the very bottom, then spray over that with raptor liner

I sealed the lid with a double bead of Gorilla white silicone.

After installing the top of the water tank, on went the back. It pulled up very nicely, hitting on all sides to the mating structure

Flyin6 · « **Reply #147 on:** October 18, 2019, 05:19:13 PM »

Then came the stiffener/flush out pieces. I used Eastern cedar, because I cut it off the farm and I just wanted some of it in there, and because bugs just can't stand the smell of cedar. And the wall will get a layer of 3/4" styrofoam then get overlaid with whatever I decide to use as a wall covering, so the boards glued in strategically give me a surface to later screw into to hang things

Flyin6 · « **Reply #148 on:** October 18, 2019, 05:21:48 PM »

And speaking of hanging things, some interior cabinet spaces are structural, purposely designed and placed to add strength and stifen certain areas. This little 5,000 BTU air conditioner will reside in a rear corner below where the roof will mount to provide additional strength

Flyin6 · « **Reply #149 on:** October 18, 2019, 05:23:49 PM »

Picked it up for a mere $129 so, why not. Here is the start of its cabinet:

The cabinet was created from 3/4" Birch plywood left over from another job/project that was donated to me
