After I purchased a Dewalt DW625 planer in 2010, doing something about dust collection was no longer an option. The DW625 has an internal chip blower that makes any shop uninhabitable in seconds. Since my budget doesn’t have room for a dust collector, I decided a dust/chip separator based on Phil Thien’s design was the most cost effective solution.
The purchased components were a 30 gallon steel trash can, two universal dust ports (from Rockler), and a 90 degree PVC street elbow. I used a piece of 1/4 inch underlayment plywood for the baffle.
The photos should be self explanatory, but here are are some supplemental commentary.
The street elbow was glued to the dust port using silicone RTV, and the dust ports were also sealed to the can lid using RTV. I used some vinyl tubing attached (with RTV) to the inside edge of the lid to prevent leakage around the edge of the lid.
Other Tips and Traps:
The first time I hooked my shop vac. to it, the lid sucked clear down to the baffle, so I installed some additional supports between the baffle and the lid. That solved that problem, but the sides of the can still collapse if the hose gets blocked or plugged. While that doesn’t affect the functionality of the system, it looks bad. Someday I’ll get around to making some reinforcements to fix that.
Using with DW625 planer: The Dewalt’s fan is so powerful that it blows the lid off the can, so I ran bungee cords over the top of the can (from handle to handle). While that partially solved the problem, additional cords were required at 90 degrees to the handles, which required drilling two holes and adding a couple of bolts to hook the bungee’s to. (Not shown in the photos.) When using the separator with the planer, the shop vac. must be disconnected as the planer blows much more air than the vac. can suck.
Here the link to Phil Thien’s web site. http://www.cgallery.com/smf/index.php There is a wealth of information here including detailed plans by our own Dbhost.
It really does a great job of stopping the small and large chips. The only material that gets through to the vac. are the real fines, aka sanding dust.
