This is a very easy to assemble 7-piece kit. There are two wheel choices. Please specify whether you want spoked metal wheels or general purpose tires. All you’ll need is some adhesive (We like CA), an X-Acto knife, some fine sandpaper, and black paint! The wheels can be mounted parallel to the body so that the conveyor simulates a front to back movement. Or you can make it with the wheels mounted perpendicular to the body to simulate a swivel movement to fill coal bins set up in a semicircular pattern. Many retail coal dealers had these set-ups during the first half of the 20th century.The measurements of this small conveyor are as follows: length of body: 5 3/4", height of built-up conveyor: 3", width 1 3/4". Many of these original conveyors still exist and have found secondary purposes. We have seen them in firewood operations, small gravel and agricultural ops, as well as just sitting in a field or industrial areas as a relic of the past. Our small conveyor is designed based upon research on conveyors that loaded coal into dump trucks or were used in car unloading along with an unloader.
