Working on that in Fusion 360! It'll be very simple overall geometry though. This is just a random illustrative image off the internet, but this...
Once I get an idea of the forces involved, I am hoping I can find standard dock or stage-truss modules with the necessary characteristics. After...
I spoke to the company, they sent a lot of photos (including right up to floating house type things) but mostly seemed to be all about flotation....
Use of HDPE in this application seems a fairly recent innovation, and I understand the more common steel / aluminum pontoon builds lean pretty...
The most common way to do it seems to be to buy the pipe with flanges welded onto it: Pontoons - NyDock Floating Docks & Pontoons PipeFusion in...
I am comfortable with buoyancy calculations etc, but looking for the "unknown (to me) unknowns" around structural integrity of the platform....
Hi all - this is related to my thread over in the Materials section but perhaps this is a better place for this part of it. Given the lack of...
Hi everyone. I'm new in terms of having an account here, but have ended up reading a lot of posts over the years at the end of a google search...
One of my kids wanted a boat. This is the cheapest, fastest design I could come up with. DO NOT ASSUME IT IS SAFE (it probably isn't). I built...
She spins like a top, with a single paddler you're better off sculling or using a coracle-style sculling draw. Lots of freeboard so I wouldn't...
Here we have about 240 lbs combined load in the now-christened Cicada, you can see the hull's twisting a bit as I'm close to the gunwale to...
The ends I slit, folded over on themselves, clamped and taped to the frame, and then bonded, avoiding all the math and fitting to the real...
The truck tarp is glued to itself and to the gunwales (but not anything else) using HH-66 a specialty rubber cement that bonded really well to...
I made the frame first, then clamped it in place and put the skin (PVC truck tarp from Princess Auto) on over top. This meant I could measure off...
I am sometimes accused of overthinking things, so I deliberately adopted a "measure once, cut once" strategy to keep things moving. Sort of like...
The skin is only attached at the gunwales, so in the end compressive loads go through the ribs and the floor, and the tension is through the skin....
With the ribs in place, you push the floor down and lash it to the keel. That spreads out the chines and tensions everything up.
To assemble, you put the floor in but with the middle up a bit, then put the ribs between it and the gunwales.
The ribs are all cut from one 10' length of conduit, and then cross-drilled to their own diameter at the ends so they catch the gunwales and floor...
The floor is in two pieces, hinged in the middle such that to remove it you untie a string and lift the middle of the floor. It has little bits of...
