Modified Paper Shredder

Polymer Craft Machine Development

Hey all, I am new to the Forum so please excuse me if this sounds off beat. Would love some feedback about a concept I have had for those looking to do some low cost experimenting.

Has anyone tried modifying a paper/credit card shredder for use in making stock material?

I am sure it will be easier to find a HD paper shredder than build the suggested machine on this project. Initial estimates I have received for just the laser cut 304SS pieces is around $600 (materials included). I am also having a difficult time sourcing the motor/gearbox here in Pheonix-AZ, USA.

Update 2016-09-12; Here is someone doing this with waste 3D printed material: https://www.youtube.com/watch?v=-yZ9crsRyws

Another idea came upon this past weekend was the possibility of using a landscape shredder/chipper.

If you want to save a little money, get the parts made out of A36 steel instead of stainless. That would take quite a bit out of the cost.

For a gearbox, just look up anyone who sells belts, pulleys, bearings, etc. They’ll usually carry a line of gear reducers and motors.

I just had the same idea of salvaging the cutters out of a paper shredder, and stumble across this post. Figured i could slap a washing machine motor on it and gear it down using some pulleys and see how it goes.
