Hey all. I finally got around to designing a proper dust shoe for Mechmate #123 and after using it a few weeks I can confirm that it is a solid design. I love it when a plan comes together.

Photo of it installed:

...and this is what the parts look like:

Brush strip was ordered from McMaster Carr (https://www.mcmaster.com/#7372T4). A 3 ft length is the perfect amount for this dust shoe.


Notes:

- Acrylic was used for visibility; Thickness isn't critical but use at least 0.25" thick material for stability; I used 0.33" acrylic that I had leftover from another job

- The upper portion is attached to the Z-slide via a 2" piece of aluminum angle

- The lower portion is attached to the top via 6X 10mm neodymium magnets epoxied into the milled recesses; Double check your polarity before you glue those magnets in!

- There is also a semi-circular front to the lower shoe that I haven't attached yet; I am going to use short pieces of brass rod epoxied into the semi-circle with matching holes drilled into the lower shoe so it is removable

- Brush strip was attached with self-tapping screws; pre-drill your holes so you don't crack the acrylic

- Dust hose fitting is secured with a drilled hole and a #8 machine screw (visible in the first photo at the bottom of the dust hose)

- Make sure you reset your max Z+ limit so your shoe doesn't get ripped off if you jog your Z too high

Questions? Hit me up. Vector PDF is included so you can make your own.

Rock on, Mechmates.

I use Kents Dust shoe on my machine now. I really like this design with the ability to see the bit. With a spindle not an air blowing porter cable.
