[RGO]

ok boys need some ideas.
how would u build a cheap flat bottom jon boat.
I am disabled vet short on money and know how.

what would be cheap aluminum,tin or what would be good/cheap

what kind of welder could i use ? / cheap ?

the boat would need to be 16 foot and atleast 60 inchs across.

I think I’d be looking at marine grade plywood, and fiberglass.
Material cost is less, and tool up will be a whole lot less!

[fdcmiami]

if i were you i would buy a used boat.

man u taking all the fun out of it with wood.

what about strong barn tin ?
and a tig welder ?

40 years ago we made one out of pickup hoods worked great .

You were the one wanting to do it on the cheap. There is nothing cheap / inexpensive about welding / metal fabrication!

To start with: I’d draw up my design; get a parts breakdown with measurements. Shop for the best price to have all the material sheared.
If you have your heart set on aluminum, look into a small 200-amp Mig machine with a spool gun.

All you have to do is order the material and cut out the correct shapes.
Tack it all together first and then weld it.
Your sizes chosen would be very nice. I would use .100 5052 aluminum.
You would be fine using the MM211 with the spoolgun.
You will probably have $2500-3000 invested by the time you are finished but when done you will still have the machine and can make more for you buddies.
Make 3 and you should be able to just about break even
Send pics as you go and keep us posted.
BTW.....B.O.A.T. stands for break out another thousand, so forget cheap altho what I have shown you would be resonable and strong as he!! if you can fabricate worth a hoot

I would look for used boat also.

Sheetmetal and some light sq tubing. But since i was a sheetmetal worker that would be like a giant piece of duct work with the top cut out...Bob

Steel would be a crappy material for a SMALL boat that needs to be moved by hand.... by the time you made it lightweight enuff to handle it would be flimsy. And it can rust unless you dipped in paint or galvanize afterward.
That is why they make them out of aluminum.
Fiberglass and wood are also much heavier as well.
Big boats are a different story altogether.

Yup you are right but when you put "U" and "cheap" in the same sentence thats how "I" would do it with what i have the resources for. Now if he said how should "I" build a good boat for x amount of bucks i would have a different answer. I worked in an old plant that made small steel boats many years ago and i saw how they were made so i could do one and it would be made from Galv sheet just like the duct work i welded for 12 hours a day at one time. Just my thoughts yours will be different.
Of coures mine wouldn't be this pretty but some good reading here... Bob
