Re: aluminum framing choices for floating docs and gangway

Hi Kevin- well, you are certainly entitled to your opinion of my strategies on asking fr and accepting or not accepting all help, and of course, are under no obligation to post or help. That said, although I have not always taken all advice given in building my boat, I certainly have taken alot of i...

Re: aluminum framing choices for floating docs and gangway

Decided to check a scrap metal dealer about an hour away today, as they said they had lots of aluminum on hand, at 1/3 of the price of new.. unfortunately, they only had one 20' length of 2.5" x 1/4" square tube, and nothing else like angle or channel.. so as I paid for that piece and was leaving, I...

Re: aluminum framing choices for floating docs and gangway

Hi Kevin - please see my crude drawings (done in paint program) . Black lines would be my heavier material for the main frame and other colors represent lighter material. That could be rectangular tube, channel or angle... Blue rectangles are the barrels on the floating dock sections. Yellow circles...

Re: aluminum framing choices for floating docs and gangway

Hi Kevin - the pics definitely explain it. Thanks. The reason for the wide gangway (6' in the middle and 10' wide at the ends) is that unlike many I see around, mine does not roll out on the dock or connect loosely to a floating dock which has it's own support system to keep it roughly in place (suc...

Re: aluminum framing choices for floating docs and gangway

Hi Kevin - thank you very much for the detailed response. The only part I don't understand, or have a hard time picturing is this part: "And, if a set of tension rods, or inverted truss rods were put below the upper surface, welded to the vertical 6" legs- say a 12" or 16" truss for most spans; then...

Re: aluminum framing choices for floating docs and gangway

Hi Bill - thanks for the input! That does seem like a good idea if I go with Channel. I could then weld pieces of plate on the edges of the legs, to form a complete box shape, where I need more strength like where I may bolt on galvanized hardware to join the docs together, or thicker pieces of alum...

Re: aluminum framing choices for floating docs and gangway

Good question. I Imagine a fairly heavy, and large dimension angle may work, but I think it would need a fair amount of more cross members, etc to make it rigid or strong enough to hold the pull of the boats in the wind versus the pulling on the gangway and crib. I would love the input of the guys w...

aluminum framing choices for floating docs and gangway

Hi Folks - my plans to build a boat cabin will have to wait another year.. My floating docks, built mainly from rough sawn 2"x8" boards for framing, with large welded metals corners, axles and wheels (for hauling in and out each year) need replacing. There were several sections which were so rotten ...

Re: Aluminum Boat Cabins

Thanks Kevin. The plans and the boat are an hour away from me, so I will dig out the plans next time I am up there.

Re: Aluminum Boat Cabins

Hi Kevin - I am planning to start on the first panel, the vertical bottom one which would be welded to and follow the curve of the sheer guard. Rather than the 1/2 height as you had suggested, I would like to keep this bottom panel as low as reasonable and therefor have a higher top panel, allowing ...

Re: Aluminum Boat Cabins

Hi Kevin - Yes, that does clear up a lot for me. The inner sheer guard on my boat does curve with the sheer. It is NOT a line. It is effectively a piece of pipe (slit down the middle) welded over the topsides at the sheer, and then has a piece of about 5" flatbar welded horizontally on the inside (c...

Re: Aluminum Boat Cabins

Sounds good Kevin - yes, the plan view design is my biggest question or concern.
thanks

Re: Aluminum Boat Cabins

Hi Folks - question for Kevin or Yofish.. I am hoping to buy the two 4'x8' x 1/8" sheets for my cabin top in the next month or so. I measured today roughly where I would like the forward edge of the cabin to start and it is about 6 feet from the bow stem.. just aft of where it really starts to becom...

Re: Aluminum Boat Cabins

Hi Kevin - you make some good points and yes, it would be hard for anyone, let alone me to keep the side straight while welding angle/sliders on to the cabin sides. I would be interested in seeing more of how you would build the sliders on a bench! I am not planning on having any back wall/ door on ...

Re: Aluminum Boat Cabins

Kevin - I really appreciated you taking the time to respond with such detailed and insightful input and advice. I understand most of what you have written, but need to digests a bit of it longer. I really like the suggestion of splitting the cabin sides into 2 sections. For side windows I plan on so...
