Dust Shoe/boot
« on: January 29, 2014, 00:40:30 am »
All, My Dust shoe
ITs in layers so you can use what you want or dont want.

Theory.
Based on 1/2" material I used Acrylic. and PVC for prototyping.

2 parts.

Main part: clamps to a router. you can adjust the hole size. it has a ring of holes for Leds.
also has holes underside for Magnets. and vents for router re direction.
Bottom shoe: Double grooves for stepped Brush material. groove can  be cut on the center line or inside the outer lines.. Magnet holes. and mating grooves for router air re-direction. as well as pass thru holes for Led lighting.

The holes for the magnets are described as. 12mm diameter (all) 3 and 6mm thick. one side is countersunk by an additional 2mm while the other side is projecting out the additional 2mm. this creates a keyed fit.

The clamp is curved to match the vents. and requires no nut as its drilled and tapped. (you could add a nut if you wanted though).

The vents which in my case is a Milwaukee router. minimizes the tornado effect and allows for better vacuum
in my opinion. though you could elect to eliminate the area that re directs and just have a complete hole thru and thru.

The Vacuum hole is a standard hole for the larger diameter hose. resize as needed.

The Led's use at your discretion. I probably wont use them but had to give it a whirl.

So cut one Main mount part.
And cut several brush parts so you can have 1",2" and 3" brushes.

Magnets I ordered many off xbay they were dirt cheap.

Perhaps more info can bee seen here.

Nice design. Having the ability to interchange multiple height brushes are a big plus of your design. Can you also share the CAD files please?

looks nice, but makes no sense.
Just the two 90 ° bends reduce the flow volume by 30 °. The narrowing in the rectangular part brings additional resistance.
Such a construction only increases the heat production of the vacuum cleaner.

Ralf, what design would you recommend ?

I had also a design like this and use a kärcher vac (screenshot1). This vacuum cleaner brings a flow rate of 4800l/min and a depression of 290 mbar from 1600 Watt. That means that this vacuum cleaner brings only a efficiency factor of 23%.
I make some tests and calculations and found that I lost with this contruction about 121.76 mbar, more then 40%.

I try now to make a new design without any bending and without any reduction. Screenshot 2.
From the calculation I lost now not more then with the tube.

I have tried several shoes of my own design, mostly the type with 90 deg bends. I am also thinking how to make a shoe like the one Ralf showed on the second picture. Oh, and I still want it to be transparent and have a look at the tool while working  ;D

THAT will last about two hours of chip flow, then GONE; back to opaque. DAMHIT

Do you think I don't know that? :)
On the current one I have a top cover part made from thin sheet of PET which can be replaced.

If you can muster up the work to make a clamping frame, real glass will last very much longer, so long as BIG chips and/or broken bits don't hit it.  You could lay some PET over the outside for shatter safety.
