Re: Conchfish AL 17.6T build
Carl, What does this system look like using 0.035" wire? The welds shown have excessive over spray- tiny droplets on the material surrounding the weld bead...that condition usually indicates the weld arc length is too long- so I'd want to increase the wire feed speed and shorten the arc length...

Re: Conchfish AL 17.6T build
Carl, If you turn the hull before welding the outer seams (?) will the building form go over too? If not (?) then I do understand some risk to deformity- but decent tacks shouldn't come undone?? It would be fine to weld the bow stem/keel seam from sheer to the aft end of the forefoot (keel seam) and...

Re: Conchfish AL 17.6T build
Carl, No need to show print stamp on chine flat once you show it's a tacked up pair of bars-plates-sheet outlines & NOT an extrusion! (I) Hate those T-joint fillets instead of outside corner joints where inside edges meet and form a natural full depth edge groove for a weld- but you have what yo...

Re: Conchfish AL 17.6T build
Carl, first the chine flat made of an extrusion?? I see the bar showing that flat has rocker and so it may rise as a buttock line forward from the transom, can't tell w/o the lines plan. BUTTT.... you refer to it as 5086- so the angle extrusion is 5086 or there is a chine flat plate and a vertical...

Re: Conchfish AL 17.6T build
Carl, this set of images shows a major (problem) question I have of the lines plan and plate development of the bottom. Image # 1 shows the panels all aligned next to one another and that confirms the two panel design is not likely needed? Image #2 shows a VERY small shape separation at the bow- t...

They are the panel to the left in the photo and the panel to the left of the paired center-line panels. However the alignment is correct-tight together, aft where they're stra...

Re: Conchfish AL 17.6T build
m32', Just discussing the seam in the twin bottom panels: that seam, if I'm correct (?), is unsupported and is visually very nearly 'flat' one sheet edge to another? Pls confirm this as all the other seams in the hull shown are of a very different class of weld joint. To my eye- that seam in the bo...

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...

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
m32, If you rivet or bolt the deck to the topsides at the shear (?) you'd have to have some flange or guard deck/shear clamp to rivet or bolt too - if I understand the question? That piece would be welded to the topsides along the shear- so why not skip that pc (shear clamp/rivet flange) and just w...

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 ...

Re: Crack inside transom
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...

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...
