Another Gentle Abrasive Material
|
Bill Welch
Another gentle abrasive material are pulverized walnut shells. I remember seeing a show about repairing and upgrading Army and Marine HUMVEE's and they were using this material to remove paint. I have seen them advertised or carried by someone, maybe Harbor Freight.
Interestingly such things as fountain pens nibs are polished by being tumbled in walnut shells. Bill Welch

A friend in SoCal was an ammo reloader and used walnut shell in a vibrator to clean his brass (probably not recommended for our brass)

For those of you who are thinking, "Great, but where the hell am I going to get walnut shells and what can I use to grind them into a uniform, small size?".......
They are sold in any fine Hobby Shop under the stealth label of "Woodland Scenics Ballast". Large (O Scale), Medium (HO) and Fine (N). I don't know if the "Fine" size is small enough to work in blaster heads but at least it will give you a base material to use in your wife's (probably soon to be ex-) coffee grinder or food processor.

They are usually used in a vibrator type machine or at least that's how I've seen them used.
