Hey guys, thought I'd add a bit more to the conversation (although its not directly related to oxidation). In terms of reducing teeth marks and whatnot, I found these guys. I purchased a set and just received them a few days ago. I used them today on my restorations:
There are two sets available for a total of eight sanding grits. For someone who has carpal tunnel issues, these things are a lifesaver. Plus, a little mechanical advantage added by the tool and the angled heads makes these nice instruments with a lot of utility. Saved me some time, saved my hands a lot of pain. Thought I'd mention 'em since we're talking stems. I haven't used them on a stummel yet, but I'm sure they will come in handy at some point.
You can find them at
Woodcraft. The ones I linked are the "lighter" set (240-600 grit).
