Hey all,

I currently have a shopvac thats been working great on Rotex mode but in RO mode I think its creating too much suction to the material I work on and its creating little curly pigtails, soft or hard pushing on the sander, slow fast, steady hand, not steady hand, it just keeps happening. I think its something to do with the full power of the shopvac I'm guessing the force is sucking down so hard onto the top its forcing scratches. I have a 1horse power Harbor freight dust collector that is currently dedicated to my table saw in the middle of my shop and I'm wondering if a full on purely dedicated 1hp dust extractor would be fine to use on Rotex 125 in RO mode. I know it's not ideal (at least I feel this way as going from this large 4" hose down to this tiny thing means usually a lot less suction but I'm wondering if it'll do.

I do plan at some point to pick up a "Y" for the shopvac and limit suction down with ducttape and pinholes but I have a project to finish this weekend.

Thanks,
Jon

Pop a bit of pvc pipe or vac hose inline and drill some holes in it?

No, will not work. You'll have no suction at all. Do what CeeJay suggested.

I turn my CT26 nearly all the way down with my RO150 and RO90.
I believe the dedicated dust extractor would have way too much suction.

The cfm are very high on the dust collectors. I’m thinking your 1 hp harbor freight has a cfm rating of 600cfm, while the Festool midi or CT-15 is around 120cfm. So at a lower setting it’s around 30-50 cfm?  Check out the ct15. Its not stupid expensive and works well albeit it’s pretty stripped down if you can live with the reality. I have a Ct-midi and it lives in the closet, I prefer the simplicity lightness and lack of bulk on the cheaper brethren.
