Dust collection with Festool and Oneida?

[mbellon (Mark Bellon)]

I don’t know what the ramifications of this are (more dust and shavings lodged in belts and drives and spindles and other sensitive parts?), but you could potentially add a collet fan to blow away the cutting area, with the negative pressure from your dust collector containing and sucking up the bad particles…

In machining we’re taught to never blow air around a mill! Only manually brush or vacuum. Don’t use pressurized air around a mill!

Why?

Because this can force particles into belts, spindles, and tools causing nasties.

The collet fan potentially creates quite a particle mess. Without a dust head, the air flow may not be sufficient to remove the particles sufficiently to avoid nasty things to the spindles, belts and such. Conceptually, if things work out, this could be a nice combo.

I think of it this way:

If you’re just interested in have healthy air one can pull the vacuum through a hole in the enclosure anywhere it makes sense to them.

If you’re interested in the safest possible healthy air and minimizing the machining mess before it even gets created, one wants a dust head… which means a hole in the enclosure and tubing within the enclosure. Based on experiments that @patofoto and I did on the Nomad 883 and Nomad 883 Pro I don’t think that coming through the sides works well when a dust head is involved. Use the front or the back. For many, the back will be more aesthetically pleasing.

Nomad: Dust Head Prototype

I have been working on a dust head for a little while with the help of @mbellon. My intention was to design one that could be made easily by people just starting. When I got my Nomad I saw ways of making it better and wished I could lean how to use it by making parts for it. This head can be made easily from one piece of stock and a couple of pieces bought online. Here is a sneak peak of it. I will start working on the tutorial soon and will post a list of parts and where to get them. [image] …

Nomad modified with dust collector

Continuing the discussion from FR4 PCB's dangerous?: Here is my modified Nomad with a custom acrylic dust box, my ClearVue cyclone, and the silencer box for my ShopVac. Only thing I need to upgrade now is my filter. [image] [image] [image] The dust box is 3 parts, the top plate that is held on to the spindle with a band clamp underneath. A middle riser compartment, and a bottom plate that holds the brush. These layers are all held together with magnets to make getting at the spindle easy.
