Kevin, would or could a extra winch on the bow make it easier to move the hose/nozzle, ??. left or right, ??????.

There will be a lot of wracking strain on those welds Kev.

My thoughts were that it would be best to have a double deck or box construction to keep the twisting to a minimum.It would be much more expensive but twisting or wracking will embrittle the aluminum and crack the welds.Nobody on here has mentioned the dredge that busted up last year.

If you built a 36" or 42" trussed railing system around the perimeter of the deck you would gain a lot of twisting stability, plus add safety from water washing over the sides and ends.
I really like what your building, and think that it will be a very stable platform to work from. Lots of good fortune to you!:smile: Dickb |

Kev,I don't know when Cripple Creek camp closes but I don't think it's that early.That railing idea sounds promising.A box deck would be heavy as well as expensive.
I had been looking at plastic pontoons out of curiosity.I really don't see a problem with aluminum ones but plastic was what I read up on.I like the take apart feature.One manufacturer uses a joint between sections that comes and goes in any kind of sea.It works well in protected waters however. |

Kevin:
I'll offer two opinions and say that they are food for thought. It's up to you to decide what works best for your conditions. 1, I would have reversed the deck lay out and dredged off the stern. Put the pilot house at the bow and built a spray shield across the bow to be able to point the bow into the swell. 2, I would make up 4 55 gal poly barrels filled with concrete with an cross at the bottom to hold them in the sand and a 3/4" rebar u-bolt that is welded to the cross and ends as a loop at the top to attach the anchor rode. The cross would also provide stability while stowed on deck. By using a 4 point anchor system you can adjust winchs to move the hull while dredging and when an area has been worked all that you need to do is re-position two of the anchors to work the next block. Lots of good fortune to you. Dickb |

That is an unbelievable amount of work that you've accomplished. Certainly looks great. You have every right to be proud of her. Lots of good fortune to you! :smile: Dickb |

Hi Kevin:
Glad to hear you made it on time. Look forward to seeing the pictures now that she is pretty much finished. You seem to have a good understanding of the pump and jet capabilities, so until you get wet and see the suction that it develops you won't know for sure if it will deliver the performance you expect. By copying a past proven design, you probably will get the results that you designed her to deliver. Thats a lot safer way to go that just building a project like this one and praying that it will work. I expect that you will be pleased with the way she works, just expect that there will be some tweaking necessary to get her running the way you want. If your not getting enough suction at the nozzle, by adding extra 10" between the jets and the flair should help. The water from the jets begin pushing on the 10" water column when the water from the jets enter the 10" pipe and the pressure from the water jets forces the 10" water column to move up the log, until friction depletes the water energy, or the increased size of the flair increases cross sectional area of the water column. All in all, I think you did a spectacular job in just 15 days. Kudos to you and the build crew. :smile: Lots of good fortune to you. Dickb |

Is that craft beautiful or what! You guys should get a contract building the next space shuttle! |

Fantastic project. Nicely done. Beautifully built.
All the best getting that Nome gold--it's bright and beautiful stuff, Lanny |

Kev,
Maybe I missed it or maybe not but what her name? She's beautiful and like you said let's hope she works as good as looks. Muley |

Well, it has been fascinating to follow this chapter in your Nome/gold/dredge experiences. You are unique in your drive and passion. I hope you learned enough and made investor contacts to build your own dredge, now, as it seems your getting close to ready to be your own owner/operator??

Kev,
Great thread! I just read your ice diving thread too, good stuff man! I feel I owe you a beer just for the entertainment alone, not even counting the great info! Hope all your hard work pays for you this year, Good luck!

Amazing, just AMAZING in that short a period of time. I'll look for you offshore when I'm there at the end of the month. MUCH SAFETY and success in filling the boat with that oro de mer....

Hey Electrumau,
Please check out " Ice Diving Thread " ( front page,) That will show you how Amazing this guy is, :smile: |

Great execution, and very impressive.
Is there a Part II to this story - how did the dredge perform in Nome? Recover your costs? What did you have to modify? Other problems/lessons? I'm in Nome the next several months, so I'll have a look and see if you're out there till termination dust.. Dylan |

Great story Kev, Great Pics too.I took some pics of the "Argo" before I left Nome so I could send them to Igor. He told me thats the way its supposed to be, not quite on the trailer with the I beam bending the pontoons,ha ha oh well, he makes me laugh too. His first few clean ups he was having someone else clean his concentrates, I strongly suggested he learn to pan and do his own clean ups.That may of helped with his average too:smile:

That is a very cool build. I know aluminum is strong and is good because it can flex, I was wondering if there were any issues with stress cracking of any of the arch members from the swell of the ocean while operating with full weight load of equipment and slurry?
Sure would love to try ocean dredging - or any dredging again for that matter. |
