I am about to place an order for a beefed up CNC Router Parts 5'x10' CNC kit with 2.2kW spindle as well as an Oneida Super Dust Gorilla 5HP dust collector. I'm looking for comments about vac hold down systems, basically whether to buy the Black Box vacs or build my own.
I've seen comments where the designer of the Black Box Vac seemed to say his 4 vac Hurricane might be equivalent to 6 Lighthouse 7123 motors using the DIY kit. He's made comments about better performance but I've never seen any reasoning for this. He also suggested that 6 vacs should be good for a 5'x10' table. Since I'll primarily be using 5'x5' sheet goods, I was thinking of going with two separate units, likely with 3 Lighthouse vacs each. This could be the Black Box Cyclone vac at $1700 each or build my own kit for less than that for both 3-vac units. And I've researched the DIY approach and pretty sure I could build it pretty easy but there are some gotchas that a commercial product may have worked out such as how to keep motors relatively cool while maximizing performance. Any thoughts? Thanks.
EDIT: Just want to point out I'm on single phase power.
