Location: florida Aluminum dory skiff Hi Everybody, Here are some pictures of the dory skiff I'm pecking away at. Location: florida Wood details on an aluminum boat Thanks for the compliment Bob, I'm putting the wood details on the boat becouse I love the look and feel of wood. Location: PacNW Rusty, I looked at that plan on the Glen-L site and they show a motor well option. Location: PacNW Well an inboard jet works better with a bit of a v bottom but if its jet power you want for working the skinny water then by all means you should consider a jet outboard. Location: florida Thanks for the feedback Hi Timgoz, I see you're a machinist, I used to run a really nice prototype shop that had some basic NC machines and a sweet welding department. I work at a specialty steel company mainly on petrochemical fittings & centrifically cast tube. Location: florida wood on aluminum Hi tgoz, Thanks, I'm not sure yet exactly how I'll build over the engine, I think I'll wait to get the engine in place and consider clearences and such. When making potentially dangerous or financial decisions, always employ and consult appropriate professionals. See that your machine OCV (open curcuit voltage) is on par or higher than the requirement of the CO2 welding wire manufacture spec. Another trick welding aluminium is to remove all oxidation on the alu where you want to weld with sandpaper or file before welding it.
From experience I have found that it is easier to push the weld rather than pulling it as an arc weld. Originally Posted by Wynand N Another trick welding aluminium is to remove all oxidation on the alu where you want to weld with sandpaper or file before welding it.
Location: Wasilla Alaska One of my Sign guy customers just bought the Lincoln your talking about getting. Location: Western Australia For what it is worth, I will throw in my opinion here as well.
The 260 amp machine was big enough, but on a couple of the heavier welds I had it on maximum settings. It sounds as though some of the people writing in this thread are learning alloy welding as they go. If you are making MIG welds without this sort of testing you are risking wasting a large quantity of expensive alloy.
Location: Western Australia Yes, I designed it specifically to give good performance between 5 and 15 knots, as I have a place on a river area where there is a lot of concern about wake damage. I have just towed the boat 500 miles north to a place called Shark Bay and it towed very well at 50 to 60 mph. It is not perfect, as the broad quarters are inclined to lift in a following sea and some active steering input is required in long seas. Location: United States I am interested in taking a 14' jon and adding a 2' tunnel turning this flat bottom into an aluminum cat?
Location: United States I would like to turn a 14x4 jon to a 14x6 by adding a 2' tunnel through the bottom of the boat. Location: Galveston, Texas cat or vented tunnel What will you be using the boat for? Location: United States I was thinking that a scooter cat would be more buoyant than a flat bottom due to its catamaran style and the fact that we made it wider from 4' wide to 6' wide. Location: Louisiana Good thread I have thought of a tunnel boat as well but only for speed.
Location: United States is there a big difference between marine grade aluminum and regular aluminum sheets.
Originally Posted by carpe_diem956 is there a big difference between marine grade aluminum and regular aluminum sheets. I know that 5052 bends a lot easier then say 5086 but I believe 5086 actually welds better then 5052 but it doesn't maybe bend as easily as 5052.

Location: United States possibilities I am really fascinated and extremely interested in these aluminum boats.
I'll most likely build a cover over the motor to serve as a sort of poling platform, although I doubt I'll be doing a lot of poling. I can do the basics but things like cutting gears and broaching and stuff like that are beyond me. Lucie, FL New to welding Aluminum I was on earlier about MIG machines and you all warned me against buying a cheap machine. Because of the torch nozzle size, it is easier to see where you are welding and it produce a better looking weld.
You can remove the closed-pore oxidation (old and foggy), and it would be replaced by an open-pore oxide layer (new and shiny). I have built several steel and wooden vessels over the last 20 years but designed and built my first alloy (28 feet) boat two years ago. This was when welding 5mm plate to 10mm flat bar for the chine weld and 28mm round bar to 5mm plate on the stem.
Helium mixtures are better for high penetration in thicker material and being lighter are also better for overhead welding.
It should be degreased and sanded clean of all old mill scale before assembly and it should also be wire brushed with a clean stainless steel wire brush immediately before welding. The spool gun might be OK, but if I had used one, I would have to build the boat differently, beacuse I don't think I could have got the bulkier unit into all the places I did. Lucie, FL Thanks for that; I am going to take a MIG course in the next semester. It is not very efficient above 20 knots, as it causes a lot of turbulence as the water tries to follow the twist or warp in the hull. The mark 2 version that I am just finishing the desig for, will hopefully fix this problem.
I'm not sure what is meant by a vented tunnel but the idea was to run the tunnel from the engine all the way to the bow. I was told that a lot of tunnel boats are square shaped when a round tunnel is better for less cavitation but I'm only wanting to go fast. This guy basically takes a full sheet brakes the sides and cuts what is the bottom plate of the boat and pulls the sides in to where he wants them. It's been over a year now and I still haven't built mine yet but I must say I have learned a ton from reading online and I'm glad i have because i would have already made some real costly mistake if I had jumped into it.
I just turned 57 last month and I've spent my whole adult life building things out of metal or wood and I really appreciate the various properties of both, to combine the two just seems natural to me.
The shoe (suction box) runs about even with the boat bottom so whatever you draw you can run in.
Sizewise I've seen guys put aftermarket jet units on 200 horse tiller motors so sky is the limit I guess. I bought the heaviest single phase (240 volt) machine available, which was a 260 amp machine with push feed on a 10 foot stinger. The oxide on alloy melts at a much higher termperature than the metal and if you do not get rid of it it will sit in the weld in flakes and weaken the weld. Although this style is not my forte, I know what it takes in the design, developing, and construction aspects, to get a finished aluminum boat to look this nice. Not sure about the grass, around here they suck river rocks which can cause some premature wear. Usually we have pretty loose tolerances, which is good as most of our machines are ancient. I have three outboard motors now and I couldn't say much about them except that the little yamaha 25 seems to be bulletproof.


I have held off on this particular welder because I am still unsure of it's ability to handle the stock I generally use.
I appreciate the offer of the spool guns but I had better hold off until I settle on something for a powerhead. The suppliers all looked very doubtfull that this was a big enough machine for what I wanted, but I did not want to go for a 440 volt three pahse machine, as this would limit its resale value. Because MIG is a semi-automatic process, machine settings and weld procedures are critical. With new plate material you can get away with just the wire brush but with weathered plate and all extrusions you have to sand or grind the mill scale off. Top speed empty has been around 15 knots and she cruises very comfortably in any sea conditions at 13 to 14 knots at about 10 to 12 litres per hour consumption.
Most boats in Western Australia are designed to go 40 miles offshore and come back the same day. I've studied a lot of pictures and the way some lay there boat out and this is mainly the mudboat guys but they have some dam good ideas.
I would appreciate any input about the jet setup, this boat has a fairly narrow flat bottom, not like a jon boat.
The other two are mercs and I've put 2 stators in the 60 bigfoot which means you get towed to the house. Now, what will hurt your weld is oil, dirt, the white residue that is left during oxidation, etc. If you make a bad weld in alloy, you will not know until it fails, which could be catastrophic. Though my goals are much more modest and my welding will be mainly in fabrication on trailers and other gear. I stretched the boat 3' and changed the framing schedule so that I could use whats commonly available in my neighborhood. Is it true that you need twice the horsepower for the same performance as a prop setup, and how big do they make them?
She was a 48' twin inboard diesel which had been donated to the school by Evinrude's widow, "Francis Langford Evinrude. If I were commercial I wound not hesitate but as a hobbyist I think my wife might think about murder. In a MIG welding course, you are taught what causes a wedl to be rejected for visual faults and whwn you are making welds that pass visual inspection you are taught how to cut the weld test piece up and acid etch it to see just how good it is inside. Just a note that the Lincoln 175 turns out to be a lower end model built for the mass market and the price jumped to $617 so I bought a new Hobart Handler 180 from Airgas.
The low cost flat bottom boat you just purchased is as buoyant as you can get, anything you do to it will make less so. Obviously they creating these boats out of composite or fiberglass but is there a business in creating these small boats out of aluminum.
The gunnels are clear pressure treated pine 1x1's laminated with polyurethane glue and stainless steel sq.
Around here we have these grass flats with this floating wire like grass that tends to clog the foot on the jet motors, some people are willing to put up with it and some arn't so you get a lot of conflicting opinions. This boat I'm working on now really dosen't lend itself to a straight inboard, too many hard oyster bars inshore.
If this worlks, you note down all the machine settings in a procedure and use then settings next time you make this kind of weld. This boat I'm building now is sort of a trial run to develope some ideas for a little bigger boat later.
