Any suggested sources/links for the right trunking or U-channel?

I don't like the other methods found on YouTube such as stapling or vacuuming the content out. (I've used duct tape before, but want a tidier approach.)

That looks like +- 15mm trunking, a very common and readily available size in my part of the world.

I've seen similar products at Lowe's, however if they have such a fairly small size, you would have to check.

Sadly I can't check HomeDepot from here, they block European traffic to their site since Europe went ahead with GDPR.

@ChuckS Over here it seems to be called raceway Lowes carries a few choices.

https://www.lowes.com/search?searchTerm=raceway

If you can't find it at a big box store up there YOu might check at electrical suppliers or security system supply houses.

Thanks both for the suggestions. Lowe's doesn't have the 15mm size (they sell something like that, but in a whole box only, not individually).

I found this at the HD site, and will go in to have a look:

I can't believe who much dirt people are willing to expose themselves too just to save a few bucks.

Especially since you buy the Festool stuff to minimize exposure to dust, and the bags are designed to minimize/prevent dust even when disposing off them.

The pores clog also, every time you re-use you loose a little more suction capabilities.

And speaking of the re-usable bags, originally they were meant for shavings/chippings and not so much for dust.

Personally I never re-use the regular filter bags. Not worth it.

Performance and price aside, how is this different from the long life bags? I'd still be wearing a dust mask and some goggles for either.

I don't do this with my later CT's as I have a long life bag in my 36 and the smaller units the bags so small it's not worth it, but I've been doing it with my 38L SR5E for 40 years. Just two bits of wood clamped on the end, dump it every so often into a large bag, no dust mess. I'm only just on my 4th bag for it in 40 years now.

The answer to the two gentlemen's question is simple:

1) I like to try things out, and finding out if the bag can be easily reused like those zipper bags sold on eBay satisfies my curiosity. Money is actually not an issue here as I just opened a new box of bags, and replaced the filled one. A box of bags (5) can last 7 to 10 years because the CT15 is mostly for the DF500 & Pro 5. Even though I've been doing tons of projects, it took me almost two years to fill up the first bag that came with the CT15.
2) Clearing the CT bag of dust won't be as yucky as it seems because I can do that just like how I clean out my d.c. canvas bag all the time -- I simply put the CT bag (cut out in the bottom) in a yard waste bag, roll and fold the top/bottom edges of both bags, and shake. Viola! No dust escapes into the atmosphere.

I could be wrong, but I don't think there's a long life bag for the CT15.

Think I'd go for a cyclone before I would bother with this...well...in fact, I did. Put a small Dust Deputy on the Altos vac that's shared between my miter saw and the guard of my SawStop. I bought a reusable bag for my CT-22 years ago. It's never been used. The thought of emptying it always leads me to ordering another batch of expensive disposables. As long as I use the CT-22 for track saw, Domino and sanding, I don't think I'll bother with a cyclone for it. I go through 1 or 2 bags a year.

I'm a big fan of the DDs and do have two Dust Deputy set-ups in use (the new DD 2.5 has just arrived, too), but the CT15 is placed next to the workbench with no clearance for a dust separator.

For me, pretty simple:

Long life bag = wood shavings/chippings and a little wood dust. Dumping that is very different from actually dumping concrete/plaster/(...) dust.

Regular filter bag = (shavings/chippings and) dust from basically everything. I use my Festool extractors on all projects, not just wood working. When it's full, the lid gets closed and the bag tossed.

That's my problem with my CT-22. I've got a cubby for it built into my main workbench with no room for a cyclone and I'm not willing to give up the convenience of it being up off the ground and tucked under the bench right where it's convenient for Domino and sanding work.

Why is emptying a CT bag more difficult or nastier than emptying a bucket of dust from the DD or the D.C. canvas bag? It seems to be me they're the same.

Since I have a bag of dust from the CT15, a bucket (half full?) from the DD and a d.c. bag (half full?), I'll go ahead -- after next week -- and dump them into a yard waste bag, and share how it goes.

I don’t have that vacuum system, but my approach would be different.

Slice off the seam.  Empty the bag.

Run a quick seam with two rows of stitches on your wife’s sewing machine. 

You should get 3 or more uses as the bag gets slightly smaller with each use.  You will lose about 1/2” each time. 

Sewing takes just seconds once the machine is out.  Of course you will have to clean your wife’s sewing machine afterwards…

I’ve done some light upholstery work, so I have an older machine that I could use. 

You can get a heavy duty Singer from Amazon.com for around $200.00.  No more difficult to use than a band saw (pretty much the same skill set).  The hardest part is learning how to load a bobbin with thread and thread the needle. 

A useful piece of equipment for furniture making.

If it works for you Chuck, it works. That's why I helped to find the right part with my first post.

For me it doesn't. I can't dump the content of my filter bags with yard waste because it's not just wood dust/ shavings/chippings.

I think it is the "baginess" that puts me off. I have a big cyclone that dumps into a 28 gallon trash can, two old Delta barrel type 2-stage collectors and the little Dust Deputy on a 5 gallon bucket. For rigid containers I drop a trash can liner over them, slowly tip them over, pull the bag all the way up, then slowly extract the can upside down. Usually get away with little to no dust cloud. I don't see any sort of bag to bag transfer going that smoothly.

Now, that's something I should try first instead of making a trip to the HD because I have binder clips and lots of scraps! I will report accordingly.

For the d.c. bag, I put the yard waste bag on its side on the ground, and then slide the canvas bag all the way in, before holding the top of the paper bag and bottom of the canvas bag together. I stand both up and shake.

Your wife is apparently much more forgiving than mine. If I even thought of running a dirty, dusty bag through my wife's machine I would get a look that would turn normal human beings to stone.

I could be wrong, but I don't think there's a long life bag for the CT15.

There is one.

https://www.festoolusa.com/accessory/204309---ll-fis-ct-minimidi-2

I stand corrected.

I have a box of this: https://www.leevalley.com/en-ca/shop/tools/workshop/dust-collection/parts-and-accessories/110576-selfclean-filter-bags-for-mini-midi-and-ct-15-dust-extractors?item=ZA204308

But the lifelong bag I looked at doesn't include CT15 in its description:

https://www.leevalley.com/en-ca/shop/tools/workshop/dust-collection/parts-and-accessories/110577-long-life-filter-bag-for-festool-ct-mini-and-midi-dust-extractors?item=ZA204309

The CT15 is just the MINI-I / MIDI-I without the fancy electronics, so the MIDI-I/MINI-I bags should work just fine.

FUSA says so right on their website. 

https://www.festoolusa.com/accessory/204309---ll-fis-ct-minimidi-2

Not sure why Lee Valley doesn't acknowledge this.  Maybe they think CT-15 owners are only price shopping and wouldn't spring for the long life bag?  Around here, we know that's not actually the case.

Yeah pretty much where I'm at. My ct midi is my mobile vac, so it's got sawdust from cutting, sanding, routing, spackle dust, cobwebs, unidentifiable dirt and grim, mouse poop, dead insects, etc.  I want none of that back in the air.
If I was using up bags fast enough to the point of thinking about reusing them, I'd invest in a separator, as I did with my workshop vac.
