Last night a scotchbrite type belt spontaniously disassembled. Felt like a whip. Got caught on the head, chest, shoulder and back.It all happened as I was twisting out of the way. It couldn't just break at the seam ,instead it had to seperate between the backing material and the abrasive. Anyway to the point of this post:Keep the safety glasses on! If I hadn't had mine on I'm pretty sure I would have lost an eye. Take care folks.

Howdy There......!
Sorry to hear that I not the only one that has them little mishaps happen. I just got my thumb out of a cast last week from a run in with my buffer. It decided that it wanted show how quick it was and how slow I am, by grabbing the gut-hook on the skinner that I was buffing. Broke my thumb in two places and split it open from the nail to the first knuckle. So Again folks please be careful and remmember that our craft is DANGEROUS.

Why is it that nobody believes me when I tell them that polishing is dangerous?
A 12" buffing wheel turning at 1800 rpm has a surface speed of 60MPH and turns 30 revolutions per second. A highly trained individual will have a reaction time of 1/5th of a second. This means that before you can react something caught in a loose buff will hit you six times. I saw a man tangle up a small diameter brass rod in a loose buff, before he could get out of the road he had sixty individual punctures and bruises in his hide. He had been buffing for over thirty years, never buffed again.

I recently had 2 60 grit belts explode on me while grinding.They must have been affected by the humidity.(They were an off brand, I no longer use them).The first one hit me near my forehead, causing some pretty deep scratches in my safety glasses.Like a dummy, I set up another 60 grit belt from the same company believing the first one was a fluke.When it broke, I pulled my hand in front of my face.The belt cut into my right forehand causing 2 very deep abrasions.Always wear your safety equipment, even if you use your machines for only a few seconds.

I almost lost a finger in a benchgrinder a few years back. It's a good thing the stone was well worn and there was enough space between the grinding surface and the guard plate.
I did get a nice view of my bone though, and a hell of a lesson on the dangers of fast moving machinery.
This actually happened before I started making knives (I was sharpening a lawnmower blade at the time), so I can honestly say that I don't have any scars or permanent injuries sustained while making knives. I'm probably one of only a few who can say that, but give me time - I've only been at it for less than a year...
Now, a question: What kind of protective gloves do you guys wear while grinding?

Wulf:
You will find that most grinders do not wear any kind of glove. It is too easy to overheat the blade and ruin it if you are wearing gloves. I tried gloves once, and always felt that the beltsander was going to rip them off. I really like to grind bare handed because it gives me better control of the blade and the heat generated. When it gets hot to the touch, I dip it in cold water. Just my thoughts.
