Construct your PVC-made dolly base, the part where your camera’s tripod will be placed. Extend the three legs of your tripod so you can measure the distance between its first two legs aligned in front of each other and its third leg placed between the back-center of the front two legs. Base the sizes of your PVC pipes on these measurements.
Place a T-shaped PVC pipe connector in the middle of the first two tripod legs, and then attach two identical PVC pipes placed on the right and left of it. As a basic guide, make each PVC pipe about 4 inches longer than your tripod’s fully extended legs.
Place a long PVC pipe with length about 4 inches more than the distance between the middle of the tripod’s two front legs and its third back leg. This is slightly longer than the first two identical PVC pipes you initially connected. Its position is perpendicular to the first two.
Connect the other T-shaped PVC pipe connector on the back end of your long PVC pipe, which is connected by the first T-shaped PVC pipe connector from its front end.
Place another set of two identical PVC pipes on the right and left sides of your second pipe connector parallel to the first two identical PVC pipes. However, since this back portion only houses a single third leg, the two identical PVC pipes on its left and right sides will be shorter than their front counterparts. As a basic guide, these pipes can be about 4 inches long, if starting the measurement from the attached second pipe connector.
Double-check the measurements of your camera tripod on top of your PVC pipe dolly base, and then mark the parts where you will place these legs.
Drill holes on top of the PVC pipe base using the markings you made.
Drill a hollow onto the middle of each your four small timber squares. As a basic guide, drill to about 1/2 inch of hollow, which should match the size and shape of the end of your PVC pipe. This is because each PVC pipe will be attached to one timber square.
Connect a right-angle bracket on the side of each timber square.
Attach the first skateboard wheel onto your timber square. The attachment should be done from the right-angle bracket connected to the timber square. Attach the second skateboard wheel on the adjacent side of the timber square, specifically the other side of the right-angle bracket.
Attach two skateboard wheels for each of the three other timber squares by using the same process done with the first timber square.
Directly attach each timber square to each PVC pipe's end using two-part epoxy, silicone adhesive or any GOOP adhesive, a retail line that provides replacements for regular glue, paste, rubber, contact cement and silicone adhesives. The timber square-to-PVC pipe attachments would include the left and right PVC pipes connected to the two separate T-shaped PVC pipe connectors. There will be two timber squares set on the left and right sides of the dolly base’s front and another two on the left and right sides of the dolly base’s back. Ensure that all the timber squares’ right angle brackets are securely placed facing the same frontal direction. This way, the wheels can properly move your dolly base for your camera's tracking shots.
Place your fully extended tripod legs onto the drilled holes you initially made on top of your dolly base. Once secured, place your camera onto the tripod.
