I never even turned the collector on when I got it. I decide after lots of reading to go the HF route and modify it to avoid disappointment.
On the top piece of the base I braced the plywood with some 2×6 – to hold the lag screws in place for the mounting bracket.
Then I flipped the whole base on it’s back to attach the dust collector mounting bracket and motor.
With it still laying on it’s back, I decided now was a good time to cut the crosshairs off of the intake. There really is no reason to have these here with a Thien baffle pre-seperator.
I really wanted to save on vertical space, so in order to keep the whole collector low I decided to sink the garbage can into the base. I cut a hole in the base and attached a sub floor to the bottom of the 2×4s that make up the base.
Here it is upright, with the can and the Woodcraft seperator lid (more on this later).
Partly assembled, waiting for the Wynn 35a filter to arrive.
Because of the height of the Woodcraft separator lid ports, I ended up moving the whole motor mount up to the very top of the back piece in order to attach the flexible hose. (This added quite a bit of re-work to the project, especially considering when it was all hooked up I realized the Woodcraft separator lid was worthless!!!).
Like I said, I probably wasted 2-3 hours fitting things to use the Woodcraft Separator lid only to get all the way through the build to realize that the lid didn’t separate anything at all. This might be a result of the size of the can, the increased airflow with the Wynn filter, or the lid just being a bad product. Either way, I was planning on building a thien baffle someday so I just scrapped the woodcraft lid (going to take it back for a full refund thanks to the 90-day guarantee) and got started on the Thien baffle right away.
I still have a 4” flexible hose I am using to connect to my tools, but I wanted the seperator to be a bit more future proof with 5” ports. Using the lid that the can originally came with and a right and left cutting snips, I was able to cut out 5” port holes pretty quickly and get the the elbow and the outtake port fitted.
Next was cutting out the baffle bottom. To cut the outer radius, I rough cut the outer circle with a jigsaw, and then used my crosscut sled and a screw to make a simple circle cutting jig for my table saw.
A few times around on the table saw (ignore the pencil marks, my compass was even more crude then my circle cutting jig!):
After figuring out the 240 degree slice, I used my square set to 1.25” (I think), and a pencil to run around the edge from the start to the finish of the 240 slice.
Finally, I just cut this slice with my jigsaw.
It’s not as precise as a router with a circle cutting jig, but it’s still plenty precise, made use of the tools I already have and the Baflle works wonders as is.
I for some reason forget to take pictures during the “sealing” and “attaching” steps. I sealed the ports top and bottom with hot glue and HVAC tape.
Once I got the dowels all in place, I set the top on the dowels and lined everything up. I traced from the bottom side around each dowel, removed the lid and drilled pilot holes from the bottom at the center of each dowel. Then I put the lid back on top and lined it all up again and set the lid in place with some drywall screws. It made the whole thing nice and sturdy.
Here is the final assembled dust collector, with the Wynn filter and all. Prior to having the Thien Baffle, using the woodcraft seperator lid, I cleaned out the bottom of my tablesaw and almost all the dust went right through into the bag! The trash can was close to empty and the bag had a few inches of dust in it. Since I replaced it with the Thien baffle, the dust no longer cyclones around in the bag and the trash can is filling while the bag remains at pre-Thien baffle levels.
After a few runs, I noted where there were dust leaks on the collector itself and sealed it all up with HVAC tape. I also added 3/4” weather stripping to the rim where the bag attaches. This eliminated virtually all of the leaks at the bottom bag.
Overall, I’m really happy with the end result.
In total it was probably about $350 with the filter and all the materials to build the base (a lot was from my scrap pile) and about 6 hours work.
