Not sure what type of boat you are planning on building,but you should look at a pre cut kit. All the longitudinal and transverse frames would be make from 5083. You should also look for a mig machine to do most of the welding. There is much satisfaction when the finished boat slides off the trailer...

If you feel comfortable with a circulars saw , drawing a straight line,and cutting by hand maybe the fastest way to split a full length of pipe. I use to put a guild in the table saw that kept the kerf open. It takes a least two people to guide the pipe thru.

Austin Hardware. Comes in a 50ft box, about $2/ft.

Hi Bob,
I know we talked ,for others this is a great link to your situation. Many different thoughts on joining plates.

looks pretty rough to me.

Sound Marine's latest delivery is a 18" launch to the East Greenwich Yacht Club.The boat is used to move large boats as there launched in the spring and hauled in the fall. The boat has a 60hp Mercury Big Foot with the new "big tiller" The fenders are held on with a s/s 1/2 twist shac...

Baywood Industries (www.bayindustrries.com )out there in Marysville Wa. make a cast outdrive spacer. I have made them out of 1" plate welded in to the stern and the cut out with a hole saw. Mercury make a drill jig guide that angles all the hole the right way.

Hate working with the shiny stuff. I don't think adding Helium will help. Helium helps when you are welding heavy material, although we weld 1" plate with straight argon (MIG) Harry if your machine is an inverter style, a green tungsten (pure) wouldn't work.Working with anodized pipe is a whole...

Looks like he ran short of rub rail on the starboard side. And yes its not the first boats they have built. Metal Sharks built a pile of Aids to navigation boats for the USCG. Nice looking boat.

A simple tow without insurance could cost $600++. The USCG won't tow you unless its an emergency. The lawyer's have the good Samaritan worried about towing you. Outboards today are like light bulbs ,there great when they work. When there broke ,you can't fix them, I think $150 is cheap.

I don't know if you can angle the tops of the outside holders . It will create a point which may not work will with the rod.

Your addicted There is no 12 step program for this.

NOPE

Your going to want to take a little silver or clear awl grip paint and paint the weld .It helps it blend in a little and keeps the weld from oxidizing . Looks good ,I hate working with anodized tube. You could make the out of mill finish aluminum and powder-coat them .. You can make the tubes out of...

Sorry, The generic white Teflon grease/ anti corrosion is sold by D. Lilly co. (online). They make radar mounts and sell hardware. there brand name is Lilly Lube.

We use a plastic washer under the stainless steel when ever we can. We also use a little Tef-Gel also. We found a generic for Tef Gel that a bit cheaper.

4043 wire doesn't have the weld strength when welded on 5000 series aluminum . It will also be softer and harder to feed. Buy a roll on line,100's of web sites or send me a PM and I'll get some to you.

I don't know exactly what they have,try Red D arc in LA. they rent XMT's and advertise they have 30A spool guns. At the very least it would be fun to play with for a week

maybe for what it would cost you to try and set up something that will be difficult to use ,you could rent a 220v machine with a spool gun from your local welding supply. Your going to need a bottle of argon any way.

Kevin is right. If you have to try ,get your self some 5356 wire. You might be able to get a 1 lb spool adapter for your machine . I think I have seen a generic one.. The most common wire size is .035 and.047. the heavier wire will feed better ,but your machine might not have the volts to get it to ...

This happened in the RIVER?? For people that are not from around here, there no local rivers that it would be safe for anyone to run 35kts in with a prop boat. Heck there aren't any rivers around here that I would run at 10kts and not be terrified that I was about to mangle my prop and lower unit. ...

At least we don't have to buy them a new boat.

The frame work look good. If your building your own boat your going to wan t to MIG weld most of the boat.

Welderbob

Hope this wasn't your boat. Must have caught the motor just the right way to break it off like that.And every day our government buys more non alloy boats.

Delivered the 24 ft'er today. It topped out at 31 knots with 3 people on board .Check out the video . Its great fun building boats ,but its always nice to see them go. The boat went up to Maine for oil clean up duty.
