[pianotech] Soda Blasting Piano Parts

In response to the question about soda blasting, I've soda blasted with
very good results. Several people have mentioned it in the past
including Larry Crabb, Dean May and Doug Gregg.

Here's a short video sample of what it looks like. In this video it was
30 degrees and my fingers were hurting so much I couldn't finish the job
on video, but you'll get the idea anyway.
