The Black Oxide Steel Bottle Adapter with Wrench Flats from NTC Trading Co takes a 1" wrench and I didn't have a 1" wrench. My large adjustable wrench was way too wide for the 1/4" wide flats, so I did some shopping in the Amazon and found this uxcell 1 Inch Ratcheting Combination Wrench SAE 72 Teeth 12 Point Ratchet imitation Gearwrench for half price. I ordered it Friday and it was delivered early, a quarter to six on SUNDAY evening. I hadn't gotten around to turning on the porch light yet, and some brave soul navigated the frozen driveway to deliver my package to the back door, as I always request. The jaws of the 13" heavy duty wrench were too wide, so I ground them way down with my angle grinder, to about 3/16" and sanded it down. I took a little too much off the top jaw which was a bit too wide until I over-corrected. Now it's tapered and the sides of the bottom jaw are approximately parallel. It could have been a lot worse, considering this is now Monday morning and I've been up since Saturday. I was actually thinking about going to bed until my package got here, then I didn't have time to sleep. It was time for work.
I don't plan on keeping this wrench in my tool box full of wrenches and pliers, since I'll only use it to screw the adaptor and a pop bottle on the muzzle to clean my .22 rifles. I have a lightweight carabiner that used to be part of an XM Radio key chain that fits through the box end so I can hang it from my gear or whatever. It's upstairs with my extra gun cleaning stuff, gun cases, targets, etc. The carabiner wasn't made to hold anything heavier than a ring of keys, but it will hold the wrench. Next I need to buy some .22 cleaning jags that push through and fall off, instead of dragging all the dirt back through the barrel like the loops I have for my rods. Instead of getting a 10 cent pop bottle dirty, I'll probably buy a bottle of limeade or iced tea, since non-carbonated drink containers don't have a deposit. Yeah, I'm cheap like that. I won't throw away a 10 cent pop bottle, but I'll spend a buck fifty on an iced tea and throw away the empty. My hands were solid black by the time I was done with the wrench. When I rinsed them off before I grabbed the bar of soap, the smell of iron wafted up from the sink, which now looks worse than the sink in a gas station bathroom. I honestly can't remember the last time I saw so much soap scum anywhere, and it didn't all go down the drain. I'll spray some Scrubbing Bubbles on it and let it work for awhile before I scrub it... whenever. Maybe before I finally go to bed, so I don't have to wake up to that mess.
