Bill of Materials:
(2) 1"x5'-0" Schedule 40 PVC pipe (for track)
(1) Pair of roller blades (for a total of eight wheels)
(16) Hex bolts for mounting wheels to wheels to platform and brackets w/matching nuts
(8) Spacers to allow for wheel offsets
(1) L-Bracket with mounting holes for wheels
(1) 3/8" plywood or MDF board for platform
(1) 1/2" dowel for spacing
Tools that will come in handy:
-A drill press or electric drill & bits.
-Nailgun or brad nailer
-Hex wrenches/socket wrenches
-Circular hand saw or table saw
-T-square / ruler
Step 2: Mount roller blade wheels to L-Bracket
Build notes & options:
To add stability you can add more wheels per "set" and by staggering these wheels from each other along the track axis. Staggered wheels will allow you to roll over seams in a track easily so that no wheel hits a seam at the same time as another wheel. Since I did not plan on using more than 5 feet of track, I chose not to stagger or add extra wheels.
Step 3: Mount wheels to dolly platform
Using two long hex bolts and washers, we secured the L-brackets in two places per wheel to prevent slip and yaw of the wheel. Take extra care when drilling pilot holes and tightening to avoid bending the L-bracket and creating an uneven surface.
Step 4: Lining up track wheels.
Step 5: Finished track dolly.
-Provide holes to mount tripod into the platform base to secure the camera down and prevent the trip-pod from tipping over.
-Add horizontal stabilizers between PVC track (especially for longer PVC track runs) to maintain parallel tracks.
