Re: Aluminium boat building - 25ft fisherman

Post by lucastefanel »

Hello, happy Easter to everybody!!
Today i started to mark the shapes for engine bracket on 5083 Aluminium plates.
I choosed (actually what i found available in my workshop) 15mm for engine installation plate, 10mm for PS and SB stingers, 8mm for platforms and 4mm for deck and bottom plates, in other words i can use my boat as an icebreaker!! :lol: :lol: :lol:
Now, of course bracket will be welded on Aluminium boat transom, but i'm thinking about anods to install in order to avoid galvanic actions between motor parts and bracket, do someone has any experience on that??
I will also installa anods on boat hull.

Cheers!!
Luca!

Because all the boat is made by 5083 plates, i use 6082 for profiles.
6061 is more indicated for other use, for example automotive.
5083 is specific marine grade aluminium.

Finally i had the opportunity to step ahead on my project.
I started to install the bottom plates (totally 4 pcs), tack welding and bending giving the right shape on hull.
Not so easy, by biceps now are burning but result is amazing! :lol:
Initially i putted in position the plates, aft plates first and then going forward.
Once position was right i tack welded plates together from outside and then from inside on the structure, in this way i have been able to bend 6mm plates!
With pulsed aluminium welding machine i made around 300 points!!
Next step will be to install lateral steps and then turn her for frames installation and sides panels!
Still lot of things to do but i'm every day more excited on my personal results!!
Here you are some pics and the youtube link for this stage of job!

Lucas...I like the project.

Sometimes pictures play tricks.

Do you know what hook is in a hull? It may be an illusion, but have you checked for it? You will be very unhappy if I am right.

Right where you are standing in the pic is the area that has me wondering. Again, it could be an illusion, but please pull a string and make sure there is no low spot between the transom and forward most flat section.
