Nomad Classic: Dust Head

  1. Can anyone point me to a suitable blast-gate type contraption that would work with the size hose used in this project? Please? I want to feed the hose out the back of my Nomad, but be able to seal it up tight when the vacuum isn’t plugged in to it. @mbellon any ideas?

My solution is fittings. One on the inside, one on the outside. I just take a piece of plastic and cover the fitting when no hose it attached. In a standard Nomad enclosure this should still be true.

  1. Do I need to make two holes in the Nomad: one for air to go in, and one for the vacuum to take the air out?

The Nomad enclosure is pretty leaky. I would try things without an inlet. If the enclosure door seems too hard to open, add an inlet hole. Make it the same size at the tubing.

  1. How long should the skirt be? How far down should the tip of the end mill extend past the bristles? Do you change brush length depending on the depth you plan to mill?

The convention is to adjust things such that the bottom of the bristle is even with the bottom of the end mill.

I never change the bristle during a job but there are those that do - make a second brush plate and mount the different length brush for fast changes.

  1. The magnets that hold the brush piece to the top mounting piece are just SO STRONG, you won’t believe it.

I do warn people about this in my Nomad 883 Pro design:

and there I recommend alternate polarity as well.

My design has the magnet mounting very tight. No need for glue… they ain’t coming out! Perhaps the current design can be respun with tighter tolerances?
