Step 1: Materials
• 18m x 50mm diameter hard PVC tubes
• 2 x T-section tubes, 50mm diameter
• 8 wheels, ideally rollerblade wheels with screws, bolts and washers
• 3m of plywood
• Some sort of shock absorbing material: foam, yoga mats or springs.
Optional (for dolly track rails)
• 6m of plywood
• 2m of 2x4 wood
• Strong glue
Tip: Ask your local hardware or furniture store for their wood leftovers.
Step 2: Tube Lenght: step 1
Decide on how long you need your track to be for the shots you need. Double that amount.
Example: I need a dolly of 6m: I need 12m of tube.
Tip: You can always make the track longer afterwards.
Step 3: Tube Lenght: step 2
Example: 12m of tube divided by 1m50 pieces, is 8. 8 x 30 cm= 2m40
Tip: Make your joints long, but not too long that they make your life harder in transport.
Step 4: Tube Lenght: step 3
ï§ a = 75cm, rounded up to 80cm
ï§ b = 66cm, rounded up to 70cm
ï§ Total: 1m50
Tip: Rounding up will give you more flexibility for the use of other tripods. Round numbers are easier to work with.
