dingahling, I'm not a fan of fully welding rub rails, but this was not my boat and I was 'crew' in the building. Yeah I designed her but I don’t own her or make final decisions for the Skipper.   "The Skipper is Always Right" phrase is the general retail trade axiom from the "Custome...

norfbay, Welcome to the AAB.com Forum.  I don't know a great deal about riveted hulls- only those I've repaired for 30-40 years but almost always welding near or on a riveted seam with a strip of elastomer as sealant made the problem worse. On the other hand rigid epoxy like castings probably will ...

Some years ago I posted, during a conversation here, about the concept of having more than one deadrise angle in the bottom of a planing boat.  I haven't found that post- had some images in it and a brief discussion of why I thought this concept would be worthwhile to build. A long time friend deci...

Doback, Welcome to the AAB.com Forum. Serious corrosion usually described pitting of some level.  Since you don't show pitting and you can wipe the white corrosion sites off the surface with a fingernail?  Then I wouldn't call it serious. From the photo you can see the hull wasn't etched of mill sca...

Spark, usually acid is sprayed onto a hull from the bottom up - so the foam has already lifted scale and contaminants lower down - then when foaming acid above flows down; there are no streaks.  This method seems to be the most reliable in terms of a uniform coloration (whitish or dull silver gray)....

Mike, I'm glad I wasn't being seen as rude and that as a designer you already know that centerline of pipe is as key to pipe layout as the keel plane of a boat!  Everything depends on an accurately drawn or designed centerline to run pipe (I used to do pipe design for oil and gas offshore here in th...

Msmithabr, I'm not lecturing, just noting that we'll need to have common terminology in order to share information about your hull and the proposed conversion to articulated surface drive from the keel boat she was designed to be. The hull lines (of any hull) are very specific and need to be underst...

msmithabr, I've extended quite a few hulls of this rough size, but all were welded hull's (or plastic hull add-ons) and this one appears to be (at least) partially riveted?  Don't know that for sure as the pics aren't zoomed in on the surfaces of the hull all that closely? In this building material,...

richas, if you drill out (the rivets) and separate the gunwale extrusions from the topsides sheet metal (?) they'll bend in very different manners. Therefore if any recovery is going to happen, you might try separating the two pieces then pressing or hammering the topsides into so reasonable pre-cru...

tonish123, this remark is based on the 3rd photo which appears to be 'vertical up'? that is; taken from the ground under the hull looking upward? From this photo I'd say the boat was formerly on bunks on the trailer instead of rollers that appear in the current photos- and I'm basing that guess on t...

Is there anyway that this could happen   That's kind of hard to answer Hunter24.  Speculating about corrosion on a few photos is sort of low quality information (as a reply). Since you know that once the internal foam is potentially involved you also know that you have to pull the deck and confirm ...

maiadash , We'd like a separate topic and build sequence pictures!  Not just a teaser that you've built-  Pls post a thread on your build?? T'trout, I it looks like you could fish the damaged boat for a season?  a little wear and tear doesn't look like it stops her from her job?  Can't express how ...

TinCup yes, that does look like flowering on un-etched surfaces and acid etching will sure knock down what's there and prevent it happening more deeply or causing damage. Could be said of any part of a welded aluminum boat.  Spraying overhead isn't the most pleasant work- full oil skins and full PPE...

Rock'62, I'd remark about the newer photos in context of the first set you posted.  1st.   I'd say there might be two separate but related instances of the corrosion in your bilge.  One seems to be the concentrated material that resulted in a very wide patch uniformly corroding the entire area of th...

Rock'62, Portable TIG is somewhat compromised over shop TIG due to the power supply requirements and the most common solutions to that equation.  I'd spend most of my time, were I in your shoes, working to get the skiff seen by a shop, in their own facility.   You can save yourself some of the costs...

Metal Health, Never met One-3 before, he's on the East Coast and I'm in Alaska, but I have built a few welded aluminum boats and will say the anyone that can build as clean a welded aluminum hull as One-3 surely- has experience with aluminum boats   I respect One-3's work as I do few builders that c...

salmonator, Zep Chemical Co. can't sell the mixture in all locations due to (all sorts of) CONTROLLED SUBSTANCES regulations in different States.  We've seen several comments here, in the past, about lack of availability in some one's area due I think to hazardous chemical regulations?  Don't have a...

one3, Thanks for helping the Forum enjoy the build of this lovely welded beauty. Went to some of your past utube vids and and it appears Bill Lincoln was involved (?) would be nice to confirm his lines? Next, and very appealing, is the extrusion and welding treatment of the shear.  Is the outside co...

one3, Sure are beautiful lines and shows a nice clean build.  She reminds me of the Bill Lincoln (Response Marine) "Rock Salt" series from a few years ago. Sure hope you'd take time to update the build photos of this gorgeous girl as she progresses through her construction? Thanks for post...

One3, very nice looking skiff, Downeast lines for certain: https://smallboatsmonthly.com/article/the-west-pointer-18/  This one in the link isn't a nice welded metal skiff but the lines are there too. Would be worth the time, IMO, to show some detailed photography of the interior and finish?  Thanks...

noex'2, A couple remarks about  bending 6061 T6 pipe. As the pipe is pulled by one part of the bender around the shaped inner die- most pipe will deform at the two edges of the die- if 12:00 if up and 6:00 is inside the bottom die the 3:00 & 9:00 are the top edges of the die.  This 'egging' or ...

Chaps, What is your impression of the keel extrusion on the forefoot?  Although I can't zoom to very close image w/o some pixelation; the extent of the pitting seems to involve the weld face and the entire extrusion? I that a picture of protruding VKB between the two bottom plates? OR is a V extrusi...

I'm bumping this thread to include some images that I may have already posted? but not sure?  I haven't found where I posted these pics but they couldn't hurt to be in this thread anyway. https://hosting.photobucket.com/albums/oo273/kevinmorin_photo/Corrosion/.highres/Mill%20Scale_1_zpsltkj9hzr.jpg?...

TN, I figured your interest was because of a 'fire sale' price. So I'll remark about that for bit. And to offer those remarks I want to tell about one of my long time, close friends, who welded for me earlier in his career and has built or worked on welded aluminum boats for many years- nearly 40 th...
