4” Dust collection

[cnc_aero (Paul Buckland)]

Hi all.
I have a Shapeoko 3 xxl with the suck it dust boot. I recently purchased and small 1hp dust collection system which uses the 4” hose. It came with an adapter for a 2-1/4” hose, which does fit into the dust shoe, but the 4” hose sometimes interferes with the movement of the router. Does anyone have any suggestions for an offset adapter or some other type of solution?
Thanks.

Not familiar with the suck it dust boot, however there are a bunch of folks that have 3D printed adapters and or purchased an extension tube to raise the hose connection up above the router to allow the hose to easily move around the perimeter of the work space.

I’m sure they will chime in.

Put a hard pipe up about 2 ft or so from the shoe, then transition to the 4" hose.

I have an SO3 XXL. Here is my setup. Notice that from the dust boot I have a straight piece of dust extraction hose. This is a rigid piece and the diving platform has enough room for the dust collection host to get to the 4 corners. I think my system works because of the rigid hose coming up from the dust shoe.

I designed a 4" dust shoe for my Suck-It mount because I wanted more airflow.

I use a similar setup as others, which is shock cord / bungie cord suspended flex hose.

EDIT: I have not had an issue with the 4" flex hose interfering with the movement of the gantry or spindle.

I ran 2.5" from the Sweepy to a point completely off the machine, transitioned there to a blast gate and 4". It’s probably 15’ or more of 2.5". I could extend the 4" and reduce the 2.5", but when I first got the machine this was the easiest way to set it up. Since then it hasn’t been a problem, so why fix it?

If you are using anything similar to a Sweepy, I wouldn’t worry too much about how the 2.5" will ‘restrict’ the airflow. By far the biggest bottleneck is the Sweepy itself.

Thanks to everyone that responded. Lots of great advice. I found an old shop vac hose that fit the bust boot and cut down one of the ridged sections that I don’t use anymore to make a union at the 4” to 2-1/2” reducer. It’s not perfect but with a little tuck tape it gets the job done. I’ll try this for a while and see how it goes.
Thanks again to everyone.
Happy machining.
