You don't NEED them, but it's a good idea to have them. From experience, standard trucks that aren't on Tech Decks screw up the performance.
First you need to get some veneer (paper-thin wood) then cut it to the shape of a tech deck. Do this 5 times so you get 5 plies. Next take some wood glue and glue the plies on top of each other. Next put your wooden fingerboard in-between two tech deck fingerboard decks. Now take two C clamps and clamp the nose and the tail. now take a regular clamp and clamp the body of the deck. Let it dry over night and tada a wooden fingerboard deck.
If you need them, put them on the fingerboard wherever you need your fingers to go.
oak or verlen wood
30mm
You need to find a CNC milling place and then just talk to them about it ;)

over 10 trucks.

You need about a 30MM wrench, and a holder for the water pump pulley.

First off you will need to decide where in the backyard you want to build the deck. Then you would have to chose the material. There are wooden decks , concrete decks, plastic decks and probably some other choices. Then of cause the cost is a factor too.
A 1 3/16" or a 30mm should work.
