This stand is made from southern yellow pine using half lap joints. You can activate the hinge without bending over. To extend the wheels, use your foot to move the pin left and out of the way and use your foot to move the wheels down on the ground, then lift this side of the stand off the ground and simultaneously use your foot to move the pin back to the right, then do the same for the other side of the stand. It works similarly to retract the wheels, just lift one side, disengage the pin with your foot, drop the stand back down, then with your foot move the wheels all the way back and push the pin back in. I used some door hinges and fiberglass pins from my surplus pile.
