Construction
The shredding and gearing portion of the JCATI project focused on replacing the chain drives with synchronous belt drives. There was little manufacturing done for this project for example, the methods used for this project was the drill press, the milling machine and the lathe machine. The drill press was used to tap the holes on the sprockets and then the holes were threaded. The milling machine was used to make the keys for the sprockets. The lathe machine was used to cut the inside of the busing bores so that it would fit on the shafts. Most of the parts for this project was purchased.

VIDEO 1: Taking chain sprockets off the shredder
This video is the removal on the chain sprocket on the shredder. It will be replaced with a synchronous belt sprocket. This modification will reduce the sound of the machine by 50% during operation.
Figure 4: Shredder with no sprocket
The chain sprocket was removed on the shredder and will be replaced with a synchronous belt sprocket.
Figure 5: Synchronous Belt Sprocket for motor shaft and JA bushing bore
The JA bushing bore is being pressed into the synchronous sprocket so that it can go on the motor shaft of the shredder.
Figure 6: Synchronous Belt Sprocket for shredder shaft and SDS bushing bore
The SDS bushing bore is being pressed into the synchronous sprocket so that it can go on the shredder's shaft.
Video 2: Synchronous Belt Sprocket for the shredder installed
This is what a synchronous belt sprocket looks like installed on the shredder.
Video 3: Final Product of both synchronous belt drives
The shredder and the gearing components operating with the synchronous belts installed.
