That's the part I like the most!

Ready to add some wood.

Today I cut off all of the rivets and pulled the carpet off the walls. Dang that was hard scraping pieces of carpet off. I have it cleaned up enough now I believe to spray on that bed liner.

Now I've got to cut the plywood bottom and prepare it for installation.

maybe you should spray some Zinc Chromate to prevent rust on the areas you scrapped.....never mind, it's not an airplane.

Me too, I'll extend that to John boats but that's about as 'maritime' as I'm interested in anymore. One minor Pacific storm on a Catamaran made a believer (coward) out of me.

Boats, to me are for going someplace in or fishing from, john boats let you go where the fish are and canoes are great for going somewheres.

No longer have it but my 18' Grumman shoe keel was the greatest canoe I ever owned (stay off the big lakes unless you REALLY know what you're doing, most people don't) and I had a 16 foot Old Town (real old, wood and canvas from the early thirties) that was a classic, but heavy on the portages. Sold it to an idiot co-worker who got tired of fooling with the canvass and fiberglassed her

'Bout what you'd expect from a former PT Boat swabby.

Any old John boat will do, great american invention, motor 'em, pole 'em or row 'em, a boat for all seasons! Stable enough to shoot from too!

... ummm, avoid high waves , 'high' being anything around 2 foot or more.

You do excellent work Pogo and I'm sure she'll be a class act when you finish ... but I do not envy you the task you have set yourself.

Not at all!

I wonder if it would be a good idea to replace the wood with aluminum and rhino line the whole inside of the boat.

It's not going to rust. It's aluminum. That is where I'm going to have that truck bed liner sprayed anyway. That brown stuff is glue. It is almost impossible to remove. I could remove it with acetone but I think the rhino coat will cover it up fine.

I did think about using aluminum instead of wood. But I went ahead and already bought the marine plywood. I think if I prepare it right, it should last me as long as I need it. I think if I have a custom made cover for it, it should last for a real long time.

After taking it apart, and seeing how it is constructed, it is going to be a piece of cake putting it back together.

There is a very light weight aluminum sandwich material that would be perfect for decking. I missed where you said "bed liner" but I see it now.

Aluminum is etched chemically to prevent corrosion, once you scrape it the etching comes off and corrosion can set in even under paint, it's a common problem with airplanes in humid climates so I assume it will be a problem in a boat.

Seems like it was a laquer type stuff, we sprayed/painted over the outside surface of aluminum.
You will definately be able to tell the scratch marks.
They turn white/powdery and that powder will rub right off.
THAT is the aluminum oxide. (aluminum "rust.")

Not trying to make anyone paranoid, or anything.

Happens on older Porsches as well. Specifically the 924/944/928 series. Their bodies are made the same way and once they get scratched real bad of someone repaints one is when they start to rust.

I wonder if you can get that in spray bombs.

Edited:

I checked a boat forum, and saw a post where they was saying to use aluminum oxide primer. I wonder if that is good stuff?

The aluminum primer is also known as "Paint Lock."
Mostly a grey paint/primer, then a good paint will stick to that primer.
You've probably noticed that regular paint has a tendency to peel off aluminum, without something under it.
Unless that paint has "Paint Lock" qualities.

*dang, aluminum boat, aluminum aircraft and aluminum siding. What a day!*

If you can get some Alodyne you can etch it yourself, just apply and wash with water after 10 - 15 minutes. Here is a link for zinc chromate. http://www.aircraftspruce.com/catalo...mateprimer.php

By the way, we had the whole airplane stripped, etched in Alodyne then primed and painted and a couple of years later already had a couple of corrosion spots.

Pogo are you gonna make it into a bass boat with two high-rise seats and a trolling motor?

I have a trolling motor that I mount on the front. That is what this aluminum plate is for. The mount
for the trolling motor locks in this plate. It is remote controlled from the drivers seat.

The front seat is elevated because the floor is elevated . I don't have my seats as high as most
guys do in a bass boat, although I could get a longer shaft that the seat sits on. I'm not into bass
fishing. They aren't very good to eat.
