Kayak cart from a treadmill

Image
I recovered a treadmill that thrown out alongside I-40 and decided to bring it home. I wanted to build a cart to hold my 2 kayak that would roll up underneath my porch and be ease to pull back out again and this looked like a great source of tube steel. I started by cutting it up with an angle grinder and finding the pieces I wanted to use. Having never welded anything before, I started with a 220V 50amp stick welder I borrowed from my neighbor. I quickly found that it couldn't be set it low enough to keep from burning right through the thin metal. So I convinced myself that I could afford to buy a small MIG welder. I bought a Hobart Handler 140 from Tractor Supply. Its a 115V welder and can work on much thinner material. The handle and pull bar attached to the front (left of picture below) were also found along side I40. As was the pipe I have at the top separating the 2 vertical posts. I re-purposed the treadmill arm pads and rubber tread-guides to cushion the kayaks against the

Bird Letter Opener

A friend asked me if I could forge her a letter opener shaped like a bird, I thought about it and decided that casting one would be better. Its aluminum so the blade will wear faster, but its a letter opener not a butcher knife so it will be OK as long as she doesn't open all the junk mail. I started by creating a model in Fusion 360 Then bought some castable wax filament for the 3D printer and printed the model. This process took a LONG time to get the setting close enough to work for me. Then I sanded and cleaned up the print and tried to make a plaster of paris mold. Making the mold worked fine, but melting / burning the wax out caused it to fail… So I printed another one, sanded and cleaned it up, then with the help of Bob Sinclair, we created an investment mold and baked the wax out for 12 hours in his oven… Then melted and poured the aluminum… The result isnt what I hoped for, the surface texture should be smooth. I think this happened because my sprue wasn&

Forged lizard wall hook

I started with a piece of 1/4" x 1-1/2" x 10" bar and and idea about making a lizard wall hook. I really wasn't sure about this one until the end when I twisted the body and gave it some life. During the whole forging process, it felt flat and lifeless, then I bent the body as if it were walking and the rest is history. The finished length is about 13".
