[pianotech] Danger!! was Journal Article

[Fenton Murray]

Ed,
Rethinking this, I thought of two fences trapping the work with the stock 
sliding along between them as it advances for each new cut. Along with my 
foot trundle that I've yet to build, I think it would be a safe operation if 
you were sober and awake.

Thanks again for making me think safety.
I don't like hold downs because you have to reclamp for each cut, besides, 
sounds like one got away.
