I made some years ago out of 1X4 lumber and brass door butts. I use rope to keep the legs together.

Each leg is H shaped with each leg being flat on the top. If you want to see a picture, I will take one and post it.

I have loaded these horses with heavy heavy loads. They don't look like much, but they are remarkably strong.

I just used them in the yard to put tree limbs on and cut up.
