Well, you wouldn’t think that a washer should cost $40, but this one is special.  Well, it’s not technically a washer, per se.  Its a piece of stainless steel I had cut to a washer shape.  You see, whomever installed the faucet in my kitchen cut the hole in the tile counter top too large, so the faucet head can’t really get a good purchase to stay put.  I made a proof of concept out of some 28gauge sheet metal from Home Depot, and it worded great.  I just wanted to use stainless so it would last forever and I also wanted it to be a good deal thicker.  I found a metal shop on my route, and they made this for me.  Now I just have to get around to installing it.
