I've got a long list of equipment I need for my shop. A dust collection system seems like all expense and very little payback. How do I justify the cost?
The justification becomes moot two hours after running all of these machines, when your lungs are filled with dust. This is a serious health issue.
You don't have to invest huge sums of money on a large system that can handle all off your machines running at the same time. You probably won't be running more than two machines at once, unless you're doing production work. The cheapest solution (depending on the size shop) would be to purchase a few mobile units that can handle a few machines independently, and move them around to the machine(s) being used at the time. As business grows, as well as running time on each machine, you can upgrade to a larger system.
