Don't worry about the discoloration, you didn't change the content of the metal, ie. it didn't suddenly become carbon steel. We weld up stainless tanks all...
Your right, actually after reflecting on this it hit me that there are already these hard spots in the hull even with origami. you would have a transverse on...
You absolutely can absorb lead thru your skin. Don't use a zinc :) have you thought about just replacing all the fittings with ones that won't cause the...
Another alternative may be food grade plastic tanks as found in RV's. As with steel tanks, they can be bolted to tabs on the frames and if the hull is already...
Hi Greg, what does the color of the tanks mean if anything?. MBQ has an article about using food grade platic barrels. I would like to know if they can be ...
Thank you for confirming NOT to use a zinc in the system! the installation had thread seal tape as well as a white goop (i think it was thread seal goop) and...
Hi could some of the transverse bulkhead issues of integral tanks be reduced with a bit of engineering?, It seems the problem is the sudden transition from...
Hot dipped galvanised pipe and tanks ie items that have been immersed in a bath of molten zinc, are often used in water supply systems. Zinc is very different...
I would advise researching this with suppliers. I generally regard translucent white containers as food grade, and everything else as suspect. I have seen...
I have a boat with a 20 gallon black plastic tank from a VW. The tank is about 1/4" thick and has a big screw on top. Want to clean your black water tank just...
Sounds like a good idea to me. We use a lot of plastic containers on the Bones, mostly scavenged. They are handy for storing just about everything, not just...
We met a really nice, round bilge, navy blue steel ketch off southern Mexico years ago. The captain was based in Costa Rica, and had the nickname "Dirk the...
Winter time here so not much to do. Got down in the low 70's today. Haven't been without a T-shirt and jeans in a coons age. Maybe another month we will be...
Hi all The white or clear containers do not like direct sun light the u.v gets them , the black chemical containers last well in direct sunlight. You have to...
Thanks for the feedback folks! Checked with Bartle & Gibson the local plumbing wholesaller who told me a> Pex is the right material to use for hi temp water. ...
Who's building a Swain in greater Vancouver (or on the Island)? Me & my mig are getting bored & want to make some sparks fly.......... Cheers, Shane ...
Rock, Could you blank off the existing tank fittings and then weld on a smaller bore aluminum pipe that you can push the plastic pipe over and clip on? ...
If you don't have success with plastic, I'd use a galvanized fitting. We use them pretty regularly on the Bones, as they are all you can get in many areas....
Origami hulls are rigid because of their tortured ends. However, this does not supply them with magical strength. Sandwich construction is also very rigid,...
We have seen lots of boats with hot water heaters run from the engine cooling. A hose runs from the engine to the hot water heater and back. I'm told there...
Greg, Intriguing stuff. Where can scantling rules from ABS be found ? Is ABS = American Bureau of Shipping ? What "simplified version of rules" do you...
Greg One minor point, on your last paragraph. While it is true that "An origami hull built to ABS or equivalent will typically be as strong as the original",...
That is something I always have a little problem with: What has origami to do with scantling (or frames for that matter)? What exactly would then be the...
I think you missed my point. I hate the fact that my motor has a sea water pump! I am suggesting running the exhaust tube thru the water tank to cool it. The...
Origami can and often does incorporate transverse framing to approximate the weight of the original. If you are willing to spend the time, you can work...
Kerr - Boat Strengths - is a handy reference and covers FG as well. g ... From: "Courtney Thomas" <ccthomas@...> To: <origamiboats@yahoogroups.com> ...
I am not a fan of dry exhaust so I skipped the postings. The exhaust on the Bones is silent and bullet proof. The fear mongering about wet exhaust comes from...
origami = folded construction Origami is a system by which you can pull a metal boat together, using the skin itself to support the weight of construction,...
