Finished a set of basement stairs, had some leftover 2 x 12s, just enough for stringers & treads, feels good to use up some free to me lumber.
Cubic Boron Nitride. Somewhere between carbide and diamond. Since the wheel is a turned metal drum, with the surface impregnated with CBN, it's way more precise and smoother than a bonded stone wheel. It'll never need to be trued. Used against mild and tool steels, it'll last approx 100x as long as a hard bonded wheel, and 1000x as long as a soft white wheel. Unless you're getting your white and grey wheels for free, a CBN wheel is only 4 to 10x as expensive as the bonded wheels we are used to.Kay, what is a CBN wheel? Uses/advantages?
Alright, a story.There is a story here...
Been there done that, I feel your pain. Ive had gas spilled just about everywhere on my body at one time or another. I would have to say that the arm pits and the **** are two pretty sensitive areas..lolWashed gasoline off my face.
You know that Dos Equis guy? He isn't the most interesting person in the world..lolAlright, a story.
So, outside, on the shed ramp, I was fighting the big tiller. The fuel pump had STB, and I was bypassing it. I succeeded in getting sprayed in the face by the pump's dying throes. Had to fumble my way to the shop, about 150', to spray my face n eyes clean in the shop shower. Do you know how long it takes to stagger along by guess n gosh and maneuver past fences, cars, machines, through the shop and find the bathroom, blind? It feels like double that with gas chewing away at your eyes.
If I didn't constantly practice getting around blind, I'd still be laying on the lawn right now, clawing at my eyes. I know it sounds like a weird thing to do, but today is why I do it. I'm frequently alone and working, so I've made sure I can get back to the house, from anywhere on the property, find relief, and possibly emergency services, without help, or proper senses. And, I try to note where everything moveable currently is, as I walk along, so I can avoid it on the stagger back. I know the feel of the plantings, the hardscape, the grade, and the different areas of grass and whatnot, so I can locate myself.
And there's your story.
(Friggin needy kids......)
As a matter of fact, I practiced again tonight. My package came late, and I wandered out from the house to the mailbox. 200', cloudy night, lights out, not a straight path, plenty of obstacles, to grab my delivery, and back to the house with my ill booten gotty. Chipped a nail on the mailbox.
Kay I truly enjoy your daily updates, you seem to live an inspired life. Not really asking, because I don't mean to pry, but I do think you could write a best selling biography of your life. Thanks for the CBN info, I guess I'm off to the store shortly for a new tool (I've been wanting a new grinder anyway so now I too will have a "**** grinder". Think I'll get an 80 grit wheel. Hope your eyes quit stinging and glad things weren't worse. I am getting feeble enough that I occasionally practice getting around the shop with my eyes closed, I think it makes good sense.

I've set mine up on the sharpening grinder, where I sharpen lathe gouges, drill bits, chisels, metal mill and lathe tooling. Works a treat. Make sure you buy the chapstick for it when you buy the wheel. It minimizes clogging.
CBN are hungry, hungry chewers. You can jam a 5/8 drill rod into it, and watch it disappear like you were slipping it into pudding. Smooth as silk. My 180 grit wheel is almost too aggressive. It definitely requires a gentle touch. If can get an 80 grit one, I'll replace my snagging wheel on the **** grinder.
A little time grinding will give you incentive to become a better Weldor.



Thanks for the lesson, one more nice thing that I was not aware of and probably won’t find that I need.Cubic Boron Nitride. Somewhere between carbide and diamond.

For me, it was a good purchase. I go through between 2 and 10 bonded wheels a year.Thanks for the lesson, one more nice thing that I was not aware of and probably won’t find that I need.
I have found that I can get along just fine, for the most part, with what I have. I am reluctant to spend my money on things that I don’t really need.

I was responding to kamccampbell's explanation of her choice of grinding wheels, a day or two ago.I think you're on the wrong forum![]()
I know - it was a failed attempt at humor...the whole thing about getting along just fine with what you have and not spending money on things you don't need is atypical of many on this forum when they learn about new tools/equipment.I was responding to kamccampbell's explanation of her choice of grinding wheels, a day or two ago.
Because you know we are all enablers here, and way too many here are either looking for the ennoblement, or are unable to resist it...I know - it was a failed attempt at humor...the whole thing about getting along just fine with what you have and not spending money on things you don't need is atypical of many on this forum when they learn about new tools/equipment.
Okay, now it's smartass kids.
I really wanted to replace the vol control with a Zigbee version but could not find one. The Nile controls are well made, I just think i cooked mine by exceeding the watt limit.I have a few of those. Did you replace it with some better?
Okay, now it's smartass kids.
I was wearing my safety glasses. I only take them off when I sleep. The inexplicable stream of gasoline from the dead, refusing to squirt, disconnected pump, shot up right along my nose, reflected off my glasses, and right into my eyes. It was a perfect storm.
Ouch!
Whatever it was - pretty cringe worthy...Belt sander ?
