Materials and Tools
Linking board mounting screws are located in difficult-to-reach locations and pilot holes greatly simplify assembly of the motor and idler ends. Pilot holes may be drilled in other wooden structural components and those will be treated in their respective assembly steps.
To minimize swelling and shrinking due to changes in humidity, sealing the plywood is recommended.
See video instructions on Motor End Assembly.
- There are two linking board pilot hole jigs for accurately locating the positions of pilot holes. One each for the left and right sides of the boards. Ream the holes in the triangular pattern with a 3mm (1/8") drill bit.
- Repeat with the remaining linking boards.
