Thanks for all the advice, I appreciate it. I'll be getting to work on this project in about 3 weeks when the Minnesota weather turns a little warmer.

My boat is a Grumman Sport Boat. It's 112 lbs., 15' 4" long, 43" wide at the widest point, 32" across the back transom, the wheels would be towards the back half of the boat, which is approximately 40" across. This would push the wheels out around 4-6" away from each side......

These folding style portage wheels were made after hours by a welder from a mining company on the Iron Range in northern MN. He no longer makes them so I need to make my own. If you guys get me onto the right size metal I'll be in good shape. I'd hate to have the metal fail on me on the portage.

Here is a shot of the "D" type mount where the wheels screw into. Screenshot (10).png Here is a shot of the handle to pull the boat. Some people use a long bar, center mounted chain and carabiner. This style clips to the front of the boat instead of bolting on a true handle. Screenshot (9)...

The flip style wheels have a common tube that spans across the width of the boat and bolts to the side of the boat using a bent "L" bracket. The "A" frame or "Triangle" wheel section slides into that cross rail which allows it to fold up and down. Some type of "D&q...

Ha, you'd be surprised how easy the portage can be with the right equipment and the fishing is world class...it's worth the effort. The other style of portage wheel you posted are the folding/flip style. The wheels actually flip up onto the side rails while in transit across the lake. When you get t...

I don't have any other pics, these are all that I could find online. I've been trying to locate someone who has one of these so I could see what they were using but no such luck. I would think 1.5" square tubing would work.

I need to build a two wheel dolly cart like in the photo for portaging my boat this year. It would need to support 1,000 lbs max. The cart uses wheelbarrow tires rated at 500lbs each, with a rectangular frame approximately 3ft x 2 ft. I need to make it strong yet light enough to carry it on board th...

Good evening everyone, new guy here from MN. After checking out several different online forums, I chose to join this one. I'm a very new, inexperienced welder and I've been doing some homework. I read two welding books cover to cover and I have been watching videos and reading forum posts for a few...
