sparks from router blade

Dec 12, 2007 9 Replies

I was just rounding the edges of end grain on a project, when I saw a few sparks coming off of the router blade. The wood is a tropical wood like teak. I had sanded the edge before I started routering. So it could be coming from a trace of sand or the wood.



Has any one else had a similiar experience?

Yep. But from homemade wood not imported. Apparently from hard wood, routing too fast, and applying too much pressure. Been quite while,don't recall what type of wood.

JOAT I do things I don't know how to do, so that I might learn how to do them.

Got that once routing mdf. God only knows what's in that stuff.

This happens when you are splitting wood with an axe--if you do it after sundown when you can see them.

Would these be electrical flashes I wonder?

Static electricity and all that?

I doubt it. Electrical sparks generally go from one object to another. These just fly out like a spark from a flint.

Not electrical in my case, and I'd been routing for a few seconds, so seriously doubt static 'lectricity. Definitely saw the spark fly from the bit. However, it is possible that I was using a HSS bit, not carbide tipped, at the time. I only used HSS bits for a short period of time and now use only cabide tipped. Only had that happen the one time

- that I know of.

I was a using carbide tipped bit when I saw it. It was like described as a spark for a flint. Thanks to everyone for their responses.

Maybe. Or embedded metal staples, barbed wire from eons ago, etc..

You can get this effect from breaking a Wintergreen Certs in half. It's a release of chemical bond energy in the form of light.
