Here is my dust skirt. It allows a 6" hose right down to the table. With the spindle you can see the bit while it is cutting. It was originally designed for a Porter Cable making use of the cooling air coming off the router. The additional air stirs up the dust helping the collector take it away instead of deflecting it outward.

Got my ShopBOT back in April of this year and learning. This is my initial try at modifying the Dust control foot. It has not been tested too much yet so there may be some improvements. It works better than the original though.

I modified the original by adding a bottom plate of ½ inch plywood, a side of 1/8 inch plastic, and a sheath for around the spindle out of plywood. Used foam where I could to seal seams. The vacuum extender is made using 4” thin walled PVC which has the built in connector. The connector width is used in the plywood bottom plate and the regular width is used for the sliding extender (can be made in several lengths to allow for longer or shorter bits). Needed to slide the pin on the original (below the wing nut) out of the way so the foot would slide into place without being tipped.

This is the dust foot I made on the shopbot. Adjusts vertically quite easily and works at least as well, from a suction point of view, as the shopbot design.

Posted on behalf of Tony Rogers:

I AM LAZY AND DID NOT WANT TO DISASSEMBLE ANYTHING TO CHANGE TOOLS. SO I MADE MY SHOE MOUNT OFFSET IN ONE CORNER. PULL ONE PIN TO SWIVEL THE UNIT OUT OF THE WAY TO RETOOL. BY USING A LOCATION PIN YOU DON'T HAVE TO FOOL AROUND REPOSITIONING THE SHOE.

I FOUND MY BRUSH MATERIAL AT HOME DEPOT, ABOUT $ 10. IT WAS A SHOP VAC FLOOR ATTACHMENT THE A REMOVABLE BRUSH.

NOTICE THE SIZE OF THE VAC HOSE. I HAVE ENOUGH VACUUM TO REMOVE CHIPS, BUT NOT SO MUCH IT LIFTS PARTS. I COULD NEVER UNDERSTAND WHY PEOPLE USE A 4" HOSE AND 2+ HP TO REMOVE DUST FROM A SINGLE SOURCE. I HAVE A CENTRAL VAC FOR ALL THE MACHINES WITH WIRLESS REMOTE CONTROL for OFF/ON. AAASIGN.com INDIANAPOLIS, IN. TONY ROGERS

That is a combination "skirt" and pressure foot for holding the work down. Here is another one like it.

If you had a rectangular material, and you cut out a rectangle of similar size, fixed the 'hole' rectangle to the table, dropped in the material, and had a pressure foot, would this eliminate any clamping, screwing, or power gobbling vacuum holddown?

Seems a possible solution for 25% of my work.
Material 2cm thick, if that matters. Shallow cuts.

The Multicam, referenced by Gerad, is very simular to the Gerber except it has a double poled fixture on a single side. This may be easier for tool changes.

Another variation on a small Aussie machine

From seeing it work at a trade show the shoe has its own z axis control.

I seem to remember that Steve M showed something similar at the ShopBot forum about 3 months ago? The effect must be similar to a table-router, albeit inverted. Should one be thinking of the spindle/router under the table instead of above?.......

Dick,

Very nice fixture. Do you think the hold down rollers, which look to be directional, could get hung up? I'd think a non-directional roller ball would be a better option. The larger the better.

Just a thought.

Hi Joe

From memory the setup had an adjustable stop or limit for how far it could go down. Say a 1/16 th or 1/8 th of an inch below the top surface, preventing it from getting hung up. The vacuum shoe was controlled pneumatically and probably has adjustable pressure as well. The sheer size of the thing limits it to do 2d work only.

A nice idea to increase the friction and assist a vaccuum hold down system. I have no idea as to the reality of its usefullness, I have only seen it in the perfect world of a trade show :-).
