I made this gate valve for my new JABOD forge and thought folks might like to see how the insides work. It was pretty easy to put together, and all the materials were screws and pallet wood that I had on hand already. Starting with the back board of the forge, I drilled a 2" diameter hole in the middle. I used a big Forstner bit for all the holes, but since the pallet wood was so hard (red oak), I had to hog most of the material from the middle of each hole with a twist bit.
