Custom Machined Track Wheels The key to the Dana dolly's smooth ride are the 16 custom machined track wheels. The wheels are custom made soft, then turned down to be round within 1/1000 of an inch to eliminate the "bounce" that normal skateboard wheels suffer from. You can park the dolly with 100 pounds of camera and accessories on the track at 100° F for an hour without the wheels flat spotting. Another benefit from the machining the wheels is reduced squeak during use. The wheels are custom modified 16 at a time on a special machine, providing uniformity. ----- Wheel Trucks The wheel trucks can swivel on the dolly, which allows it to ride on straight and round track. A felt washer separates the dolly platform from the wheel trucks, helping to reduce noise. The included T-Tool features a 1/2, 9/16, and 3/8" ends. It allows you to tighten the wheel trucks using the 9/16th end to suit your taste. ----- Mitchell Mount The Mitchell mount features an elongated key way, allowing you to use non standard adapters. ----- Track Supports Track supports fit into available standard Junior stand receivers or 5/8" Baby pin, although Dana Dolly recommends the use of available beefy baby stands at a minimum and to avoid thin walled aluminum stands
