My question is , if you use brushes , such as a door sweep how would you see to zero your axis. Is clear plastic a better option. Thanks, Mailman
I see lots of posts for dust collection, I've seen several working/attempting to work, and I've even seen many that have given up letting the machine make a mess while the operator leaves the room and cleans up after.
I purchased a used machine and the dust collector foot is one of the very best I've ever seen. It is a rectangular aluminum tube extending down the side of the spindle with two brackets holding the tube firmly but not inflexibly from above. The rectangular tube is welded 90 degrees at the base and extends through the center of the spindle. A round hole the size of the largest bit you would use plus a tad clearance cuts through the tube and a cap on the end maximizes the suction/collection. The spindle/collet can extend through the base almost to the bottom of the base. The base is a 1/4" piece of abs attached to the bottom to protect the material surface and provides a slippery but softish surface for the dust collector to slide along, the edges are rounded to allow the dust collector to slide up should the table surface/material not be perfectly flat. It works so well for 90 percent of all sheet cutting, I have no cleanup afterwards, and I can sit at the end of the table with no material left in the air. I simply raise it an inch to zero a new bit (don't have an electronic zero plate), then simply push it down until it his the surface, the abs is great a sliding but not scratching any/all surfaces.
I even created some dust boots with bristles like you described for those times when carving 2inch plus material with very irregular surfaces which are the only places where this boot seems to start to break down, but none seem to even do as well as this one even in those rare cases.
Oh in case your wondering, I do not have anything approaching the cyclone shown in the previous thread, rather I'm using a home made velocity trap on a trash can to drop anything larger than fine dust particles between the router and a, don't laugh, harbor freight 2hp (read as very inexpensive 110volt) stock dust collector. Only the finest powder gets past the garbage can so I've only dumped the dust collector once though it is due again. I've dumped the garbage can MANY MANY MANY times.
