Dust Collection - minimal sized ShopVac..

Post by BellyUpFish » Tue Jul 28, 2015 2:36 pm

Just wondering if something around 2.5hp would be sufficent to keep up with a Shapeoko? All my shop vac experience as always been "buy the biggest thing they have.."

I'd like to grab something to sit under the workbench full time to do the honors of dust collection.

Anyone using something this small?

something with a large collection bin would be ideal. I have a smaller ridged vac that im using right now and I have had it fill up before the last 15 min of a 2 hour job and make a huge mess. I even had one wheel on my x axis get clogged up and break. the small vac had more than enough sucking power it just doesn't have the storage space.

The biggest problem in my opinion is the filter in the shop-vac. A lot of the dust from milling is very fine and will stick in the filter, so it soon becomes clogged.
The solution to that is to make or buy some sort of 'separator' system such as a 'cyclone' device that gathers the dust into a special bucket or sometrhing before it can reach the shop-vac.
And the problem there is generally that you don't see how full it is...

My solution will be PET bottles using this design:

I just need to figure out the measurements and print it first...

I'd have the vac hooked to a Dust Deputy that would live on a 7 gallon bucket.

Man, that cyclone is awesome. I really need a 3D printer, but maybe after I have half an idea what I'm doing with this Shapeoko.

I thought Id throw this out there for anyone else that needs ideas for a vac system. i'll clean up the wiring once I make some brackets to hold up the ivac and rout the power into my table.

im using a 4 hp metro vac, it has a very small capacity but it's the strongest little vacuum I could find. un believably strong suction for it's size. it's stronger than my rigid shop vac and much quieter. it has a very small capacity though with the bag inside it that couldn't hold more than your average purse. but the debris never makes it to the vacuum because the dust separator sends all of the dust into the 40 gal bucket. I can fill the whole yellow bin without getting any, yes any, dust in the vacuum. the vacuum also has a washable bag made out our your regular old denim jean material. the Ivac isn't really necessary but it will be nice once the rest of this table is sound proofed with insulation and closed up. the spindle and vacuum both plug into the Ivac, once you turn on the spindle it turns your vacuum on for you, and when you shut it off it runs the vac for an extra 15 seconds or so before shutting it off, it also let's you put the router and vacuum on separate circuits. I turn on the router, cut the part, turn it of and move on. just have to dump the 40 gal bin when it gets full.

I got it all with amazon prime.
