The Material Yield from a Lexmark Color Jetprinter 1020

A while ago Bative mentioned that some good, machined, mandrels could be acquired if old printers were busted open and gutted. Following this advice I found a Lexmark Color Jetprinter 1020 for $1 USD at a yard sale and bought it. After bringing it home I immediately smashed it apart with a four pound sledge hammer. I was rewarded for my efforts with the following mandrels:

The top four "mini-mandrels" are two inches long and 3/16" in diameter on their widest parts. Beneath those is a ten inch long 3/8" mandrel. The bottom mandrel is twelve inches long and 5/16" in diameter.

To make the effort even more rewarding I picked through the shattered remnants of the printer and found some lovely spring steel coils.

The measurements for these are as follows:

Large black spring in the bottom center - 2" long with a 5/8" inner diameter.
Very small spring in the top center - 2 3/8" long with slightly less than 1/16" inner diameter.
Top right - 3/4" long with a 5/32" inner diameter.
Shorter coil beneath that - 3/8" long with a 1/8" inner diameter.
Set of four on the left - 5/16" of usable coil with a 5/32" inner diameter.
Short coil above the big spring - 2/16" of usable coil with a 3/32" inner diameter.
Coil below the top one - 7/16" of usable coil with a 1/16" inner diameter.

I hope that is report helps to encourage more people to make use of "useless" printers and other equipment. Good weaving and happy hunting!
