The dolly platform
Step 3: Attach the angle to the platform
For the dolly platform, use a piece of 3/4″ (18mm) thick A piece of wood made of three or more layers of wood veneer laminated together with glue. 30″ (760mm) wide x 42″ (1060mm) long.
Note: That particular size suited us. You can make a platform to whatever size suits you.
Lay the platform upside-down on a couple of sawhorses.
Draw a line along the length of the platform, 3 1/2″ (90mm) in from each side.
Lay the two aluminum angles next to the lines.
In other words, the two aluminum angles should be placed each side of the platform, 3 1/2″ (90mm) in from the edge.
Screw through the screw holes into the platform.
Note: The screws should be long enough to go almost through to the other side of the platform for maximum hold.
That’s the platform. Now for the tracks.
