Extended track + (Tensioner)

The center distance between sprocket 1 and sprocket 3 was increased by a few inches to adjust the spacing. A chain tensioner was integrated into the assembly, which required drilling with a 5/32-inch drill bit for proper installation. The main body and tensioner were subsequently secured using adhesive (e.g. super glue), eliminating the need for screws. Also the shaft is for a dc motor.
