Building the main turret board
The rst step in building the main turret board is to t the board in the chassis. Use ve M3 shakeproof
washers and nuts to do this, but for the two mounting points at the bottom-left and bottom-right add
the M3 solder lugs. These will be the grounding points for the board's components.
Now join the turrets shown with the three wire links:
• a bare bus wire that runs from the ground lug at the bottom left edge of the board
• a bare bus wire that runs from the ground lug at the bottom right edge of the board
• an insulated red wire as shown here.
Solder these wires around the shaft of the turrets, leaving the turret holes empty and ready for
components.
Once again, for insulated wires, it’s best to tin the end with
solder and then bend it to create a ‘hook’ that you can place
around each turret shaft - shown here in step-by-step
form). Use needle-nose pliers to crimp the hook around the
shaft of the turret and then solder it into place.
