Use your tin snips to cut a length of metal to match the size of the training board. Bend metal at each corner and make a short cut enough to bend the metal into a rectangle as long as the training board. Attach drip ledge to back board with 9/16-inch bolts and nuts. Install u-bolts wit the "u" on the outside of the components and over the component to be secured. Use your electric drill and 1/2-inch drill bit, and drill holes for u-bolt installation.
Place the u-bolts through the holes to secure the piston and tighten the nuts on the back side using your open end box end wrench. Tighten until bolt is secure but do not over tighten as it will break the wood back board. Repeat procedure until all components are secure. Different sizes of u-bolt will be needed so measure the component to be secured to determine the bolt and nut size.
Use your reciprocating saw and make three slots for each side of the can holder. Push the metal holder into the slots made for it. Use your plastic hammer to gently push the can holder into the three slots. Use a bolt and nut long enough to go from one side of the can holder to the other end. Use the bolt and nut to hold the can holder in place.
Understand that the pressure gauge should be connected to the distribution block for the most accurate reading both at high and low pressure. The digital motor speed sensor should be attached with a fast acting glue after your electric drill and bit to make a hold for the motor wires. Insert large eyelets to the motor wires and attach to positive and negative terminals on the battery. The rpm meter will only operate when motor is spinning. It contains a pressure gauge inside that stops gauge from reading until activated.
There are literally hundreds of circuits used in the field. The training board can be changed to fit most hydraulic systems without actually crawling in the mud to fix something.
