Interoffice Communication TO: Steve Ashby FROM: T. G. Grumbles DATE: July 11, 1984 SUBJ: SHOP VENTILATION T-36. =- 4C V<L^ I have marked the pages most applicable to the application you need for the saw we looked at. (VS-401 and VS-709) As you will see the book recommends enclosing the operation, but I don't think that would be necessary or practical based on the materials in use. A design more similar to VS-709 should work well if all unnecessary openings were sealed and an overated fan were used to produce enough velocity to capture the metal shavings and get them to a baffle trap. As we discussed, the book is "for keeps". X- Thomas G.
