The AntiVirus Ball Roller
Built by Les Chatfield in June 2020
This model was built to utilise two caterpillar tracks for an unsuccessful Ransomes MG1 model tractor. They took so long to assemble I didn’t have the heart to take them apart so they rattled around for years until I built this model specifically to use the tracks (by now joined into one extremely long track).
Tensioning is provided solely by the large tyres fitted to the plastic ring gear wheels (one of Meccano’s best new parts).
