Local source for tubing
not the tow-behind/water sports kind.. i'm looking for stainless or aluminum bimini type tubing. 7/8" and 1". got a project in mind. i've checked lowe's website and they have some aluminum, but i think stainless might be a better choice. maybe one of the canvas shops or something?

off the top of my head, i'd need two short lengths of 1" at least 24" long. for 7/8", probably three 5ft. lengths would do.
the project is a hardtop overhang. the aft edge of my hardtop ends directly above my seats. any water on the roof ends up dripping down on the seats, and you if you're sitting in them. terrible design really.. so i want to make a removable extension to eliminate that problem and provide a little extra shade too. my idea is this.. mount two 24"-ish lengths of 1" tubing horizontally to the outside edges of the hardtop, one on each side. think receiver hitch. then build the top extension itself consisting of a frame made out of the 7/8" tubing and a starboard surface on top. the 7/8" will slide into the 1" and mate up against the aft edge of the hardtop effectively extending it. i haven't come up with a good way to secure it place yet though. maybe a couple 2-piece latches, pins, or set-screws. but i'll figure that out when i get there. |

thanks dave, that's ok. i appreciate it though.
i figure if i mount the fixed pieces first, then build the frame it should come out ok. that way, i can put the frame "legs" in the mounts so they'll line up. |

That's how I'd do it. Metal work is fun. I'm in the middle of a metal project for my boat right now, as a matter of fact.

George is closing down M&M Marine Salvage in Meredith and getting rid of everything, but there is still a good pile of ss and aluminum Bimini tubing if you get there quick. He's always been very fair with me about price.

I bought a bunch of tubing from OnlineMetals.com recently and they had 3/4" thin-wall alum 6061-T6 tubing really cheap as I recall. Just keep in mind that shipping cost take a huge jump at 96" long. So if you can get them to cut a couple of inches off it might save you a lot of money. If you are going to bend it, you'll want a different alloy. I'm sure they can recommend.

i agree, i really enjoy it. welding in particular, i love making and building stuff.
side note.. i think mounting the 1" tubing to the hardtop is going to be more challenging than i anticipated. the sides of the top aren't straight so there's going to be a bit of an angle i'll have to compensate for somehow. i'll attach another pic so you can see what i mean. i've been looking for stainless mounting brackets that may work, railing hardware, but i'm having difficulty finding something i think will work, but still be sturdy enough. another thing i'm re-thinking is the length of the 1" "receivers" mounted to the hardtop. originally i was thinking of making them 24", which is about the length from where that "<" is in the middle of the top. i'm now wondering if 12" length mounts might be stronger, it would have more support in a shorter span/length. effectively, less of a fulcrum. and yet another thought i had was instead of having the mounts horizontally, perhaps vertically mounting them could be an option too. i don't know.. i have too many ideas floating around in my head. i just need to spend some time with it in person to iron some of this out. that project looks to be a bit more involved than mine! what is it? |

My project is a compound curved, 3/8" thick 60" long aluminum bracket to fit over the top of my transom. I will be mounting some custom aluminum davits (the white part in the photo) to it. I cut the aluminum and bent it to shape, but my 200 amp TIG would barely blemish the thick aluminum. My buddy has a HUGE Miller MIG with a 30 amp spool gun and he effortlessly welded it up for me.
My advice would be to mount the SS tubing with custom 1.5" thick HDPE brackets. HDPE is really easy to machine with wood working tools and is perfect for exposed boat parts. |

thanks for the offer and advice dave. much appreciated! i may end up going that route, but for now i've got everything ordered. for mounting/support, i'm going to try some 1-hole stainless conduit straps. i'd prefer 2-hole mounts, but the upper hole would require me to drill through the side of the roof, which isn't a hug deal, but i would have to remove the headliner to be able to secure the bolt with a nut/washer from the inside. and to remove the headliner, i'd have to remove my electronics box with all the electronics/wiring etc. it's just a huge can o' worms i'd rather not open if i can avoid it. i'm going to try the straps first and see how they do. if they don't provide enough support, i'll have to come up with a plan B, but i think they'll do. as long as i don't do chin ups on the thing it should hold it just fine.
i pulled the boat out today and brought it home. i'm doing this top extenstion as well as installing an ez-steer setup on my kicker motor. right now, the kicker is steered by it's own dedicated steering cable, and i've always had trouble getting enough left turn out of it. it's been adjusted 3 times and it still won't turn left as much as it should. 2 marinas tinkered with it and so did i, but i think it's as good as it can get. it just isn't enough. i can't turn left into any kind of wind while trolling, and that just doesn't work. |

my plan for using starboard for the overhang has changed. apparently, i have a sheet shipped to me costs more than the sheet itself. and to order one from a local place is just as expensive, $600!! uh.. no. so, i'm going to give plan B a try. i bought a 4x8 sheet of 3/8" pvc at lowes for $79. we'll see how that works out.
