starbright, Welcome to the AAB.com Forum, as welder has mentioned, build sequence image posts are always widely read here, hope you'll share yours?

Re: Chasing corrosion around fittings
Ethan, the pictures seem to indicate your builder's paint job didn't include an etch and chromic acid conversion of the surface to chromium oxide- accomplished with chemicals like Allodyne on wet rinsed acid etched 5000 and 6000 series aluminum? The mill scale seems intact in the images, but the co...

roamer58,
5052 will weld to 5086 with 5356 alloy fillers and will work to patch holes, corrosion areas or other defects in the original hull.

Re: ID old gulf coast boat and ideas on refurb
Hey Justin, welcome to the AAB.com Forum.
The links don't open for me? and I don't see images in the text? In fact, on my display I see the string printed out.
May want to edit the post to see if the image attachment feature is OK maybe its just my old PC?

Re: Conchfish AL 17.6T build

Re: Crack inside transom
Hard_Way, First the transom bolt doubler 'pan'. It appears this is a bent piece of sheet and the bends look like they were done with a knife edge brake die? This resulted in a weakened piece of metal due to the strain hardening of the bend areas; by not using the correct (4T Radius Upper Nose Bar ...

Hard_Way, To directly answer your question about the inner transom plate; yes you should open up the void to see what's inside. If the inner plate is the liner to a void that was created as a 'sandwich' or double sided built up 'box'(?) then it may not have been stiff enough internally? The bolt he...

ModG, welcome to the ABB.com Forum and the discussion of aluminum boats.

Re: welded hull structure options
chille51, Welded boats’ hull panels are quite thin compared to the hull sizes they form. As a result there are a couple of different ‘types’ or purposes of framing elements. Not that all framing isn’t intended to contribute to a very strong, rigid hull but there are main frame elements and ‘local’ ...

hatcher, looking at the Grady video there were several term revisions that are examples of how we (all) mis-use our terms sometimes. The intersection of the topsides panel to the bottom panels' outer most 'edge' is a The Chine. This is a single line of intersection - not a flat area - but a single...

There remains a discussion of structural framing ideas but the shape that meets the water is what mainly determines ride. Only issue I see is the idea of trim tabs and transom r...

If you leave the hull's chine to chine beam the same between two boats of the same LOA and (relative) displacement you could sharpen the deadrise/V bottom angle by putting reverse chine flats insid...

Hatcher, JonH, "RIDE" is a big topic to try to converse about online, being that it's in text not eye-to-eye and on the water boat testing together in a controlled circumstance. So someone who's spent a lifetime in nearly flat bottom work skiffs will think even a slightly warped bottom 14...

Re: welded hull structure options
chille51, I did use transverse deck beams but.... they don't touch the hull directly so they're dropped into notches in the hull longs or were extended down to shorter hull longs w angle legs laid against each angle and flat bar intersection in plan view. https://hosting.photobucket.com/albums/oo273...
