If you are thinking of building your own small CNC engraver or 3D printer and need various shafts, oillite bushes, ball bearings, servo motors, timing belts, pulleys, screws and other bits and pieces for free, then read on: I need some small timing belts and pulleys for a project and McMaster Carr doesn't ship to Australia these days. Looking around online, I see some local suppliers want around $30 for a 25mm aluminium timing pulley and have a 50 day lead time to supply it. So after a bit of thought, I asked a local copier company if they had any old copiers I could scrounge parts off. It turns out these days they have to send them off to E-waste recycling and they had 3-4 big machines waiting to send off to recycle that they were happy to let me rob for parts. Now the old copiers I worked on 20 years ago were analogue machines with a single main motor driving the entire machine through a system of belts or chains and electromagnetic clutches to activate the relevant part of the machine. These days they have done away with that method and use servos scattered throughout the copier to individually drive parts of the machine. At any rate I had a good assortment of mainly Gates Kevlar timing belts which were found mostly in the document feeder and the collator unit rather than the copier, the other parts like servo motors were just in the way of getting the belts out so I put them aside while disassembling the Toshiba copier. These small parts look like new and haven't been touched since assembly, best of all they are free. Feeling lucky with this score, I decided to push my luck and asked a local engineering company if they had any drops of stainless steel bar used for making boat prop shafts they could sell me (usually better machining than 316 alloy). The foreman was about to hand me some 2" diameter bar when he paused and looked me in the eye and said "Are you a Yachtie?". The receptionist looked over the counter at me nervously and once I denied being a yachtie, he handed me the 10" length of bar and said "It's free for you, if you were a yachtie it'd be $100". Obviously too many down on their luck sailors have stiffed his company for services rendered before sailing out of harbour late at night, never to be seen again.
