Dust collection for us isn't an issue. We have a very larg central system (100Hp fan). It has enough suck at the machine to easily suck up 6" square pieces of 3/4" mdf right off the table if they aren't sucked down. The machines are equipped with an air jet to assist chip removal.
The vacuum hold down is drawn down to about 20inHg most of the time plenty of hold down. We really don't have much trouble with tool breakage most of the time. Unless a collet is worn out or something stupid happens. ----- Original Message ----- From: "Gene Heskett" <[email protected]> To: [email protected] Sent: Tuesday, May 24, 2016 5:00:54 PM Subject: Re: [Emc-users] Tool Marks?

The air hose works well too, but blows the cuttings all over the shop, and had to be used about 8 squirts per loop around a .375" square button. As thats about 10 passes thru the loop=80 squirts, the air compressor was running pretty hot. So I much prefer the spot vacuum that sucks it up the instant its loose, and all the mess is contained in the 5 gallon catch bucket my el-cheapo version of a cyclone separator dumps it into. My vacuum nozzle is circa an inch in diameter, so it also sucked up quite a few of the ebony parts. But the lid on the bucket was never snapped on, so shutting off the vac and lifting the lid to retrieve the teeny parts was quick and easy. it could have been even smaller in diameter, but I ran out of space for down step adaptors, and its a 35 mile round trip to Lowes or a 50 mile trip to home depot for more parts. So obviously that gets done when I need something else too. If I happen to remember it that is. :) [...] Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
