[pianotech] Danger!! was Journal Article

[Ed Sutton]

Fenton-

Your front and rear fences are a good start.
In the accident I saw, there was a sort of lever driven hold-fast which was 
supposed to clamp the workpiece with downward pressure against the table. 
The guy was running a short section of pinblock scrap. The hold-fast 
slipped, the piece spun around, demolished the hold-fast contraption and 
knocked into his hand. The sharp edge of pinblock material cut deep.
A hold down of some sort would be good, but don't take away the fences.
