Here is my build thread, about 20 topics down the list.
'Alumacraft Jet Jon Project'
I will update it later this week, as I will have the floor & carpet in by then (I hope!)
I chose a difficult way to go about bracing the jet ski hull insert. I use some recycled jon boat ribs, but they had to be 'tapered' due to the jet ski hull tilt. So I cut them length ways & rewelded them with my funky welder. I am confident it is not going to come qapoart but the welds were butt ugly. I welded solid aluminum chunks inside the channels, then drilled & tapped 1/4 -20 to clamp the jet ski hull down.
I know I go on & on about this stuff, but this has been the best project I have done for a long time!
BTW, I will be getting it re-registered as 'Homemade', so it will be completely legal. There is no inspection required for a homemade boat (I called the coast guard) but you can't sell it to anyone.
