No.. I don't think so!?

But, I was reminded of the rock this morning after making a few welds on the trailer. Welding stainless will display many colors that almost look like "iridescent hematite" and few will ever see.



The plate was welded to the front of the trailer frame for mounting the "jack wheel". The plate is 304 stainless steel, welded using 308 rod and tig torch.



The stainless weld must get a coating after going "liquid" that causes the different colors? Titanium will also show this condition.

..but if I start seeing "ruby" and "sapphires"...
I'll head for the mountains!!

Hey Wayne,

Maybe I should put a torch to some of our less iridescent hematite specimens to perk them up . . . or more likely blow them up!

You probably did create some. And you have quite a large amount of #9 lying around (at least in surface area, if not carat weight). Aluminum metal is not stable in an oxygen atmosphere, but does create a thin coating of oxide to protect the metal below.

The colors can tell how good a job that you did welding (at least what the oxidizing potential was during the weld):

Wayne,

The new Aluminum river fishing boats are all welded and even have a special coating on the bottom to protect from rocks. The old ones where all riveted and tended to split and to leak like a sieve after a few trips through the rapids using the Jet motor full blast.

My old canoe is riveted but it has 1/4" thick aluminum sheets that I have yet to see any rock bother. They just dent but don't tear like the modern ones they made for speed out of thin sheet aluminum. The Fiber Glass ones can't take the beating of shooting the rapids either. Mine is also a "Laker", which has a rib on the bottom for steering in high winds. This tends to hang up in low water though. But the thing is all but indestructible. It's been through the "Foul Rift", like a waterfall with one narrow slot you have to go through in very fast water, area here on the Delaware River and almost all of the river plus a few in N.J. quite a few times. It's also part of the reason my knees gave out from "Portaging" it on my back. It was made by "Apache" over 50 years ago and looks just like it did when I got it. It has a few character dents and scape's. The seats are a clever idea too. They are made of the same material that those old folding aluminum chairs were made of. I updated them with "Seat Belt" grade material. They are a lot more comfortable then sitting on bare aluminum. You might even be able to fit it into that new trailer you are fabricating or add a neat rack on top.

My old buddies and me used to run the river a few times during the year when we were younger. Eight of us with 4 canoes and a custom trailer. They all went through 2 or 3 canoes and mine just kept on going. The "Rift" tore a few of them in half and gouged slits like the Titanic in a few. Duct tape was a miracle tool when it came out. It would seal up a slit in no time and they could be on their way. When it got one of them and bent it around a rock it just stayed there until the river level went down. We could have used a good welder in those days.

In those days you could party and have fun, then pull up to an island on the river and cook up a few fish or some "Dogs" then sleep over night and finish up the trip the next day. People just didn't throw their trash around and always brought it with them and left everything like it was when they got there. It holds a lot of rocks too. A Geologist who works for the Geologic survey here in Pa. told me about a place to get Petrified Wood. You only had to paddle a few miles on a lake then climb up a steep cliff top get it. Most of it is still there but some fit nicely in my canoe after I threw it into the lake then fished it out after rappelling down the cliff.

Hi Joe,

Several years ago, I design a small boat to run the small rivers and back waters to trout fish from and to have a little "fun".
The design was a modified tri-hull. I had already priced the metal and had an engine that could be bought. I never followed through with that project, wish I had... or maybe it's best I didn't?
The engine was from a seadoo jet ski with over 100 horsepower!

Hi Wayne, don't feel bad, I'll bet we all have a string of projects either started and not finished, or never got them off the drawing board. I have more than a few . . .

Wayne,

My son has a bigger Aluminum boat that he uses to fish the rivers here and up in Canada. He has a "Jet" type engine, there are no props on them, to get into areas that a prop engine can't get. It scares me a bit when we skim over rocks and rapids to get to areas but we get to Striper and Small Mouth spots that others can't. The Jet type engine has advantages and disadvantages. When there is a lot of dead vegatation the jet tends to clog up since it has to suck in water to expel it out for momentum and the filters can get clogged up and the engine doesn't like that. You have to clean them out before you get going again. That Jet Ski uses the same propulsion method. Since all these engines and the prop type are water cooled you don't want to run them without plenty of water going through them.
