First I had a wall mounted shopvac that clogged regularly and didn't have much suction. I bought the Dust Deputy and a new filter for the vacuum. This was a very nice upgrade for the underpowered vac, but needed more power. Having already purchased a Dust Deputy it was perfectly clear to me that the CT Mini was the best yet cheaper option for dust collection.
I attached the dust deputy's second bucket to the top of the CT Mini using 1/2" birch plywood, and use that bucket to hold the first bucket for all collecting. Simply set the lid aside and life the dust bucket from the "holster" bucket and dump. I used the clip locations on the bottom of a systainer to take measurements and spacing of the attach points. The CT Mini's built-in clips can take 1/2" tabs cut into the ply. My next task is to cut two 1/2" mdf disks with holes in the center to mount to the top and bottom of the Dust Deputy's lid to keep it from flexing under pressure. Even with the argument that the self cleaning fleece bags will prolong the life of the HEPA filter, but with the DD the filter will last the life of the vacuum (I hope anyway). I filled the bucket up once and checked the bag and there was only a slight discoloration from dust in the bag port, otherwise nothing there.
For all interested the Festool Clips accept 1/2" tabs. Each pair of tabs are 3/8" wide with a 1/4" gap between them. The socket is 1.5" wide in all.
The whole setup. Both buckets are used from the dust deputy kit. One is bolted to the plywood and the other is easily removed to dump.
Only three of the four green clips fit on the plywood tabs I cut. I'm not worried about the fourth, it's plenty secure just with three tabs. The tabs were drawn in and cut out using a bandsaw and cleaned out with a coping saw and triangular file.
The 27mm hose on the CT Mini fits perfectly in the top port. The blue hose was purchased at Lowes and I believe the connector was already attached to the hose, don't hold me to that though. I am looking to replace the blue hose with a non antistatic festool hose later.
Two and a half inches of dust and chips collected so far. The bucket was dumped twice since getting the mini and was half full both times in a span of about a month of ownership.
The brown discoloration in the bag's port and three minor chips are all that's in the bag after about four to six weeks of daily (minor) usage. With so little making it into the bag, I imagine that the one bag (self cleaning type) installed with the unit can last years. I may never get the chance to use the second bag that came with the unit.
