[TheForge] air table

[Craig Schaefer]

Yeah, you're exactly right.  I don't know why I said 'compressor'.  Even if 
you only had 1000 holes in your pegboard, if they were 1/8 inch each, you'd 
have over 12 sq inches of hole to put air thru.
Check my math for me.   Seems like a hell of a lot of 'hole'.     1000 * 
(.0625)^2 * 3.14159 =  12.27
