Re: Aluminum Pram question

Not real familiar with the style of boat you have but I assume it is a flat bottom boat. If so the easiest one is to take angle iron and weld it to the bottom. Turn it so the corner is pointed down and weld both flanges to the bottom. Do not weld it solid but about 4" on every 12", staggering the we...

Re: How to keep a raw aluminum outer hull looking good?

You may want to email Kevin, he is pretty sharp on this type of stuff. I personally have never had any experience with anything other than painting the hull that will keep it from becoming discolored. What I did to keep it looking good was to use a white 3M pad with a real sudsy soap and clean it. B...

Re: Scrambler update

Charles, for the motor issue just disconnecting the battery if everything is grounded back thru it will be sufficent. Use the method I emailed you for the gas and you can actually weld on the tank with no issues.

Re: MIG welding Aluminum

Yea, I remember you talking about the tig gun. I have never used on aluminum, although I have used an auto feeder for SS pipe welding years ago. I really would like to try one sometime. You made some incredible welds you showed here several months back.

Re: catarman power

I have made several trips on a 21' cat powered by a single 200hp OB. I have also made a lot of trips on a 22' cat with twin 90hps. No comparison between the two. Even with less HP the twins seemed to get up on top and run freer than the single power did. Also it was a lot easier to turn the boat at ...

Re: MIG welding Aluminum

Kevin, do you use the pulse or pulse on pulse modes for any of your alumunim work any? I build a lot of fuel tanks in the 80-135gal range for a local shop which does a lot of boat restoration projects. I primarily use .125 5052 for the material. For a long time I tigged the tanks out totally which o...

Re: MIG welding Aluminum

I wrote this to Kevin in a private message because I did not want to distract or contradict anything he said. He suggested I post it in the forum. He is very knowledgeable and there is a wealth of good info in this thread. I have been teaching welding for 24 years after working in the field for 15 ...

Re: Scrambler update

I used 2"X2"X3/16 angle for my side rails. I actually place mine about 8" from the top of the sides. I ended the rails about 4-5 from the front so I avioded the hard turn as the boat narrowed in the front. I actually drilled holes from the inside on 6" spacing and did the welding from the inside. T...

Re: Scrambler update

I know what you mean by the progress going slow on the detail work. When I was building on a regular basis I said I would have liked to just built the hull and done all the welding and then turn it over to someone else to do all the finishing and detail work. Too boring and tedious for my liking.

Re: bear cat

If I could let me caution you about cats. I am a huge fan of cats and have a set of bearcat plans I bought back when KH was still designing the plans. My plans were to build the 28' version out of aluminum. However when aluminum went sky high I back off of my dream. I did buy a hurricane damaged pro...

Re: Scrambler update

Sorry for the slow reply,,, had a couple of 16hr work days. You have plenty of bracing and supports in the transom as well as the rest of the boat. Looks like the twist came out very well. Keep the pics coming,,, nice looking build so far. The boat is not a lot different from the ones I use to build...

Re: Scrambler update

Glad you got it out. On your deck questions. I am a huge man (6'6" 280lbs) so I put mine at 16" centers. There was still a little flex and give but nothing to be alarmed about. Unless you go with a .160 or .195 I think you will always have some flex in the metal when someone stands directly on a dec...

Re: Scrambler update

Us "termites" do appreciate the skill and work you put into your craft and medium. I welded boat trailers for Magic Tilt Trailers many moons ago, but have never worked with aluminum I have a Miller-Matic model 35 Mig, but will stick to steel for my street rod builds, and wood for my boats!!! :wink:...

Re: Scrambler update

Charles, Don't worry about what the termites think. I have said a lot of times I would like to buy the first boat I ever built and sell it for scrap metal. The man who now owns sees no flaws with it. I promise you the warpage in it was worse than I see in yours. However if you can get it back to lev...
