Description

Thank you for thinking about this product.  This is a Dust Boot System specifically designed for my Shark HD500 CNC machine fitted with the Shark CNC 2HP 110V water cooled spindle.  With that being said, it most likely works for any of the HD series machines with that spindle and bracket combo since it looks like they all share the same head just larger work envelopes.  But I have not vetted any dimensions beyond what I have in my shop on this particular machine.

You can buy Shark’s dust boot for $100, which is Not for a 4” hose, does Not have strain relief as it moves around, and Does look like the fastest thing they could throw together.  I’m a Mechanical Engineer who owns and operates a custom fabrication shop, and I wanted something that was thought through for my machine and me as the user.  I also wanted it to look sleek and perform very well. I believe cutting wood is fun, but cutting your life short because of cumulative dust inhalation is irresponsible. The cost for proper dust collection is spread over the years of your life.  It’s invaluable.

This dust boot not only looks great but it connects with a standard 4” air hose for maximum CFM over the part.  Starting from the bottom, it uses a 4” tall bristle.  This tall height lets me not worry about it going over clamps or higher layers of my work piece.  The bristle ribbon nests into a track in the removable dust boot, and secures without glue or fasteners.  This boot has 4 strong magnets to dock it to the upper housing.  Its profile wraps around the housing of the spindle so putting it back in position is literally a snap.

All magnets of the boot and upper housing are pressed up to a registration shoulder so you can’t mess up the depth, don't have to use messy glue to hold them, and they'll never pull thru.  Drive them home and let it go.  The upper housing uses a captured nut and washer as a clamp mechanism and a socket head cap screw with a printed knob that lets you loosen and lock the housing position with zero tools.  This easy clamp design gives me over 2” of vertical travel to adjust the height of my dust boot. Vertical travel is granted by how much of the spindleYou’ve left under the CNC’s spindle bracket.  The 4” entry opening of the housing shapes into a curved oval of equal cross sectional area. This ensures you have not hindered the CFM, and the curve shape better distributes that air flow around the cutting area.  That lofted shape is also designed to not interfere with the spindle bracket in any vertical position.  The Infill around the clamping diameter is Concentric to allow that to operate like a hooped flexure, while the block area around the bolt and nut is a heavier Gyroid infill for compressive strength.  Infill elsewhere is Support Cubic to use material efficiently while maintaining the structure.   All the large pieces use a 3 layer perimeter for overall rigidity and strength.

The final piece is a strong hoop that’s hard mounted to the machine's spindle bracket.  This feature adds strain relief to the hose when the machine is moving in X and Y, and ensures the housing only feels the air moving through it, not the tug and pull of the hose coming from above.  The strain relief hoop allows the housing and hose to move vertically through it when you are adjusting the clamp.

In closing, this dust boot design goes together with basic tools and there’s no glue or tricky things to do.  It has an incredible amount of CFM to keep you from breathing that dust for years to come. It’s specifically designed forward facing and no wider than the actual machine head, so it can never hit anything.  The dust boot comes on and off fast.  The tall bristles means the upper housing is up and out of the way while you’re working spindle wrenches.  And if you Really want it out of the way, loosen the knob and slide it up.  Easy.

Invest in your health; That’s Priceless.  Stop breathing dust and put down that shop vac every time you run your CNC.

Thank you,
