Found this real hard plastic stuff at work so I tried making a wedge out of it.

[Wolverine]

I had 2 wedges made from delrin about 20 years ago for use on the printing press. We wedge corners up so the sheets jog more even. That stuff can be brittle. I chipped one when it fell out of a skid. I still have both of them though. I'd never take a hammer to it.

I JB'd it back together. Kept these as a momento to the printing days of my career. Brings back a lot of memories. Made in probably '94 or so.

I needed that wedge yesterday. One of my friends dropped a tree that got hung up on anther one and sat on top of the stump, refusing to fall. Lacking a wedge like Wolverine and MercMan shows here, we had no choice but to tie a rope to his truck and the base of the tree and pull it loose. We could have wedged it loose from the stump with my dead blow hammer and this wedge.

In the end, we brought it down and now I have some good firewood, but I have once again learned that whatever can go wrong will eventually go wrong: a version of Murphy's law. A simple drop suddenly became a PITA.
