    Nice, how will that hood over top work for dust collection?

    My belt grinders also throw sparks and dust to the rear. I figure the hood in combination of a dust catch underneath. It should catch most of the dust. I had a bucket of water underneath of it up until this point. But I cant handle the dust in my shop anymore. I'm gonna mount my dust collection motor outside. I'm gonna put around 6" of water in my seperator drum I built. Hopefully this will solve my dust problem. I still have to build 3 dust collectors for each separate grinder. I'm gonna put dust gates on each machine.

    One little tip, even with the gates & water, never grind woods, then steel without cleaning the collector system. I had a fire start in the hose & collector:oops: .. Made for a few frantic moments when with my respirator on, Huh? I smell something burning and then grabbed the fire extinguisher and saw that smoke was billowing out of my wet/dry shop vac collector :rolleyes:

    I appreciate the advice. I've got a shopvac set up with a mini cyclone for wood. I'm gonna make an adapter so I can disconnect my 4" hose on the collectors on the bottom side of the machine and just use the shopvac for wood.

    I think you have a better chance of sucking that dust down rather than up.

    I'm gonna add a dust collector on the bottom of each machine also. Plus the hood. Dust also gets slung to the back. My shop is a disaster after 4 yrs of grinding. I've been using a bucket of water resulting in metal dust in the rafters on the wall studs and in every crevice and crack of the shop.

    My shop(s) have gotten dust incrusted no matter what systems I’ve had, unless you can put in a large cyclone system? Anyways, once a month or so, I have cleaning day from top to bottom and even hired people to help or do it completely. Sometimes. I have Hearing issues, Huh? What??? and it hurts to hear the vac system at times, doing a full clean up!

    Ok it may work but I use a ~5hp shop vac for mine and it's still not ideal suction. You may want to upgrade that at some point :)

    His 1 Hp motor and your Shop VAc 5HP rating are not at all comparable

    I would guess that his industrial 1 HP motor is more powerful than the shop vac.

    The shop vac power rating is absolute marketing bullshit.
    It relates to "peak" vs RMS averages of the AC sine wave

    a 1 Hp motor is at the limit of fitting into a breaker 120vac, 12 amps.
    a 5 hp motor in a 120vac plug would absolutely not work within a 15 or even 20 amp breaker

    I think the blower is around 1300 cfm. If it's too small I will go to a 3 hp 220v eventually. I'm gonna mount the motor outside in this weatherproof enclosure. I got the enclosure for free 20190830_121802-574x765.jpg 20190830_121820-574x765.jpg

    ahhh that makes a lot of sense thanks for explaining that!!

    that looks great! Would you mind posting a pic of the blower you are using? I would like to look into something similar but not sure exactly what to get. apparently I've been misled this whole time haha
