coffee grounds?

That's a blade grinder. You can also get coffee grinders that use a burr. With those you adjust the grind by the position of the burr. They're harder to find and more expensive.

Thanks, John... the whole grinder thing makes more sense to me now... I'll have to look into a couple of those (1 for wife, 1 for shop) since my wife is a coffee "gourmet" and I'm a "red can" sorta guy.. *g*

Hi Mac

One grinder should do just fine, just borrow the "gourmet" one, you could even try some new wave coffee/red oak taste or java/walnut, there might be some money in all that ground bark

Have fun and take care Leo Van Der Loo

Point of fact, Solid glass micro-spheres are a b*tch to sand. However, hollow glass micro-balloons sand extremely well. They are the resin filler in the 'light' autobody fillers.

Other good epoxy fillers are talc (easy to sand, filler used in most autobody fillers), phenolic micro-balloons (purplish-brown in color), mini-fibers (white polyester), Cab-O-Sil (fumed silica thickener). I've also used ground walnut shells, and calcium carbonate (ground marble).

Waitasec, He can no longer turn, or no longer finish with CA? HUGE difference. Dan

What you are describing sounds like a 'whirly blade' grinder. A burr grinder has a cutter that looks just like the burrs for a Dremel, or air grinder. Want more info? visit alt.coffee Dan

The easy tactic is to buy a pound of el cheapo coffee beans at the grocery store and use their grinder set to 'espresso' for extra fine grounds.

In plastic resin systems, a filler is anything that replaces the resin. Usually done to alter the physical qualities of the resulting composite, or to reduce cost. They are usually in the form of small particles, i.e. ground coffee.

A reinforcement is something added to increase tensile strength or flex modulus. Most of these are fibrous, as in wood fiber, glass fiber, carbon fiber, etc.

Once encapsulated by the epoxy the coffee smell will be negligible.

Robert! I resent this. Posting this twice in two different threads, on the same day, creating two discussions is not only poor protocol, but falls under MY definition of 'mother henning.' cluck, cluck, Robert.

Sounds a little odd to me, too- he can't even turn with a good respirator? Granted, I don't know all that much about it, but I'd think that as long as it isn't getting in your nose/lungs, it'd probably be a non issue. Some stuff will cause dematitus, but all that needs is some lotion.

I don't think so, Leo.. I might have to drink some of it too...

the problem that I had with the ones that she bought (probably very inexpensive) is that they were colored... gold, silver, red, couple of browns, etc.... and the color was only on the surface..

They looked interesting in the crack until you did a little sanding, then they were just a dull gray..

If he can no longer turn then sounds like it was the wood that got him and not the CA. Wonder what he was turning.
