Anyone ever try toothpaste as a lapping compound or finishing media?
If it could abrade hardened steel imagine what it would do to your teeth! I have used toothpaste to polish scratches out of CDs but never tried it on metal. IMO if you can feel the grit between the fingers it is too coarse anyway for finishing it did. Conversely the large particles might break down and polish nicely as you work it.
Give it a try and let us know how it works!
Ironically i used it to polish up a few stained blades etc.... never as a honing compound. I will give it a go on denim perhaps next week to see what happens with the edge....i suspect it will do the same as chrome polish on denim.
Toothpaste on dental floss is great for rusty pivots(so I have read) and baking soda demolishes oxidation on my Japanese knives after cutting tomatoes and onions. I think iron oxide is softer than the steel, but I am clueless actually lol.
Dude, if I had a room to myself, no kids bugging me, I would sleep! LOL!!
I hear you brother....been there already...lol.
Ah, long trip?
Toothpaste has an average particle size of 8 microns... though I doubt it's got the consistency of the particles found in hones and abrasive pastes.
FWIW, a friend who collects high end vintage tobacco pipes uses a toothpaste that contains baking soda to polish his vulcanite (rubber) pipe stems. He doesn't want to have them buffed. He has shown me before and after photos, and the stuff works, but he says it is very slow going.
Tried toothpaste several times, does nada for the edge. Cleans dirt off, but not better than a lot of other things.
