Re: 10" in 13 days

That thing is a beautiful work of art. My favorite thing about mining is the fabrication process. I had no metal working experience until I started building mining contraptions. Just remember the golden rule: don't turn your yet-to-be-mined gold into some other lesser-valued metal (iron, aluminum, etc).

Anyone know the status of that dredge submarine on an excavator undercarriage in Nome? I heard it went out once and hasn't left its fenced 'sub pen' since.

Re: 10" in 13 days

trnelson,the amphibious submersible dredge sits beside the road in the penned in area you mentioned.The owner has put his hopes into a clambucket dredging operaton and I don't know how that is doing.They were hard at it last season for extended periods with that clamshell operation.

Word was the sub got some water into its hydraulic system but I did not ask the owner so it may not be accurate.

Sheesh. For such a beautiful contraption you'd think they wouldn't just give up because of a leak. Must have more money than ambition to see the machine pay for itself.

Looking at this thread has my engineer going in overdrive...lol... I was looking at building a ship, boats go in lakes..lol... tell me if anyone has used this material for decking..http://www.mcnichols.com/product/6715316324?navCode=cc:bar&navCode=avc:swgrecbar2&navCode=avc:bargrtswaged2

looking at the strength to weight on it, impressive..

thanks,

Jeff

I have installed it and it's a good product. They also make a similar product out if fiberglass with Tungsten carbide grit on the surface. It's nasty to touch and will sand the bottom right off your shoes.

Most of the time I see tread plate used as decking.

Here's a hot link to your post, you need to put the link on it's own line.

So how did this rig do, it's impressive but I was hoping to see how well it pulled in the gold?

Re: 10" in 13 days

Sloane, I think it was Mark Twain that said something to the effect that, "A mine is a hole in the ground with a liar standing next to it." I'm not disparaging anyone.

Few miners will be completely open about their success. Some will brag about their modest successes and many will tell you all about the problems they faced and modifications they MUST do to achieve success. I would contend that most just get by from season to season and admit it. Many have to take a day job in the off-season. Expenses are real high. Air freight eats cash fast and that is the only way to get needed repair parts in. Then factor in the weather and the season gets real short real quick. Even a few great days might fail to cover the season's expenses.

Would you brag about getting a bunch of gold on a public forum? Nicht ich. But it sure would be nice to recover enough gold to be in the position to decide about whether or not to brag.

Hi Kev:

Interesting report on the boat. The diesel should not be running dark. The injector pump is probably not set right. They set them in the factory to run at max load. A good diesel mechanic can lean it out to the point that it's running at the same load point on the pump but only burning enough diesel to develop that much Hp. The black smoke is excess diesel that is not being consumed by the engine because the load of the pump in not enough to burn it.

Looks like the new build is comming along well. Keep the photos and reports coming.

Hands down the most exquisite of vessels I've seen headed to Nome yet. You guys are seriously something pulling that off in the time frame you did. I'm sure you are, but I'll say it any way you should be proud of your baby! WOW!Cant wait to see it up close..

Re: 10" in 13 days

Looking really good Kev, I really like the undercurrent on this box, it shows this is getting on in your number of builds. I also really like how you used the new angle and curved connections for the jet, this should solve the problem with the 22.5degree angle slowing suction you saw with the Argo. This being an existing tritoon platform, you answered the question, what to do with the tailings over the center toon as well.. Looks like you have the majority done. I sure can't wait to see her up close.. God bless and good mining...

Re: 10" in 13 days

I am tremendously impressed with the scope and detail of your work. I worked for Frank Wade, founder of Offshore Pipelines, Inc, one of the world's largest pipeline burying outfits.

Your efforts are commendable, sir, and that is from someone who was there on projects of a scope of a magnitude of 10 of this project.

Your project is well thought through. It is well planned. Reality takes over, and then it succeeds or fails, according to so many variabies in the equation.

At least you have anticipated and planned for many things that most newbies just ass-u-me, and then find out about later.

I wish your project well, and I can see quality planning, welding, design, and other things.

There are three things that are vital to any gold mining operation: picking up the ore, separating it, and extracting the last 15% of the fines. If any one of those falls down, the end result suffers.

Concentrate on those three. Fancy systems are nice, but remember:

The old guys used to take rough sawn lumber and make sluices, and come up with some respectable quantities of gold.

It's all hair splitting. Do the basics, and after that, it is what it is. If you hit those three areas accurately, your results will be as good as they will be.

re: anchor points: on the large barges I worked on in the Gulf of Mexico, we used four or eight point anchor systems. I would not go with less than four. With two, I think you'd spin a lot.

Re: 10" in 13 days

As a weldor since 1974, I must say that I am impressed. I see what looks like a gun in one picture, and in another what looks like a SpoolMatic. Just what welding processes did you use on this, and what machines? Did you use any pulsed MIG? Lastly, which alloy wire did you use as filler and why? Which shielding gas?

Very nice work.

Re: 10" in 13 days

The first inspsection after the first year's use should be highly interesting. MIG does have some negatives, lack of penetration and cold lap being a couple. You will flex and load this to the max during the first month by just loading up the pipes and bringing on board a lot of material. I will be interested in your reports of the first inspection, and how everything held up. IIRC, you said some people gave you advice for extra gusseting, etc, and it will be interesting to see what held and what worked loose. There will be a lot of flexing, and a lot of cold water. Not to worry, the next one will be much better.

Re: 10" in 13 days

I am Feeling a tad bit of looking down of ones nose in some of the posts on your thread here Kevin. I personally think that this is going to be one of the most productive of vessels we'll see on the water this summer. If one thinks that what has been created in this project of yours is in any way lacking or that they can create a better piece of equipment in the same stature and size, or their skills of fabrication are superior to yours , or that you have no clue as to what your vessel can endure at sea, or even if they have a crystal ball that can predict your outcome of your next project, let the pictures fly!!! Otherwise lets keep it positive on here This dredge is an example of perseverance, ingenuity, and good ol' determination. So when we feel the urge to offhandedly condescendingly compliment another's work, let us first remember where we started ourselves, and TRULY respect the hard work of others even if we would have done something differently. Looking like we'll be admiring mediocrity Kevin cause I still haven't seen a new thread!!!:confused::devil:

Re: 10" in 13 days

I have no surviving pictures of a 8' x 20' trailer I built to mine placer in Mojave county, Arizona. 5hp pump, 2 incher, 10' sluice, trommel, 100 gallon recirculating water system. Three times, we did 2 oz. in one day, less, other times, you know how consistent gold mining is. I have no surviving pictures of offshore platforms I helped build, erect, or service, nor any of the underwater work we did. The pipelines are underwater.

Other than that, if you go to Hoover Dam, you will see my work all over the place. I will not bore everyone here with the listings of what and where, but it is there. In Las Vegas, I still have commercial structural steel that's standing. Miles and miles of fencing, and ornamental metal. Water and Power Building in Boulder City, NV. The awnings may still be on the enlisted men's and officer's mess halls at Nellis, AFB, haven't been on base lately.

Then there's all the structural welding that is covered up and not visible.

As to building a gold dredge, I don't see anything I could not do, given the time, equipment, and money. It's just metal. And some of the stuff I have seen, I would not lay claim to having laid a hand on it, it's so bad. Who cares if anyone has built a bad gold dredge? And who judges what is good and what is bad?

The dredge under discussion sure looks pretty. But I'll bet you a double pepperoni pizza that they find problems the first week. And make changes. And identify outright mistakes. And find bad welds. We just do our best, and roll the dice. Or stand to the side and criticize.

I have decided to stick to my dredge head(s) ideas, get them patented, and make money while sitting at home. Alaska already seems to have its share of unique people.

Re: 10" in 13 days

Well, when you find someone to give you the money to build your Nome dredge because of all your great ideas be sure to post pictures so I can point out all your flaws. Your ideas so far hold no merrit and they come off as nonsense because you lack the experience. The dredge won't work, but I'm sure all your welds will hold.

My reputation preceeds me as someone who can build and operate a succesful dredge. I am a proven commodity. I don't build dredges to sell them. I build them to staff them and pull up gold.

I will do my best, which is better than good enough and you can stand to the side.

-Kevin

Hi Kevin:

Looking real good. See the end in site. Safety pipe should do the trick. Nice shots of the sluice. Trailer should hold her nice and tight.

What's her length and beam? When does she need to be at the barge?

Keep up the good work. :smile:

Re: 10" in 13 days

Kevin, would you PLEASE make notes of the welding failures, and their failure analysis? Causes - flexing, vibration, lack of fusion, collision, etc. I am always interested in things welding, and would like a recap, and think it would be highly informative to all fabricators and weldors here. Failure analysis is highly educational. At least for those of us who don't know it all already, that is.

Re: 10" in 13 days

Attitudes change real quick when confronted with an actual challenge,seems we all have an opinion but very few have the actual experience of doing a build like this. I am taking pictures and building as we speak and just before we leave for Seattle we will post pics. I cant wait for the master fabricators to point out all my mistakes, it,s going to be awesome!!! She isn't as big as the juliana but she will be a fine vessel for my first build..

THANKS FOR ALL THE INSPIRATION KEVIN... God bless and good mining. -Bill- :doublethumbsup:
