I have a Delta dust collector and the cloth dust bag attaches with one of those band clamps. Does anybody have any tips on how to do this? I get the bag on and when I try to attach the clamp, the bag falls in the back. How do you hold the bag up while attaching the clamp? I know I’m not the only one frustrated by this awful attachment system, but someone out there must have figured an easy way to do this. Help!
Some clarification: My dust collector is the type with a cloth bag on top (filter bag) and a cloth bag on bottom (collection bag). As far as I can tell, the only way to attach the collection bag is with the metal band clamp.

In the Tips section, I remember a suggestion you could add a cup hook to the machine and an eyelet to the bag to hold it in place. Self adhesive hook and loop tape attached to both would probably be simpler though.

I have used rare earth magnets to hold the bag up until I can get the clamp locked. Lee Valley or Woodcraft carry and they are not expensive. Works great.

Nowadays I have workers who change the bags so it doesn't bother me. But long ago when I worked alone I fixed 3 little spring clips (of the type you get in stationery stores)around the circumference of the collector to hold the bag while I set the clamp.

When using the cloth bags, I have used a bungie cord fitted around the metal part to serve as a 'belt' until I could get the band-clamp in place and locked down.
Since I use the plastic-type bags on the bottom now, I use the 'magnate-method'. I don't think the magnets I found would hold the cloth bag in place.
I have the Delta 50-760 and recall having issues with the cloth bag as well. I use the flexible inner band to hold the bottom plastic collector bag and the band clamp for the cloth bag on top.
I first place the open band on the impeller housing then hook the top of the bag in the vertical holding rod. Then I put a bungy cord around the bag which brings the bag up short of the hole.
I then work my way around putting short strips of masking tape on to hold it in place around the opening. Then start the band clamp from the back and work my way around till it's in place and snap it closed.

A Woodworkers mind should be the sharpest tool in the shop!
It's a wrestling match, alright. I just 'cuss until I finally get all the little bits in the right place - usually after several tries and lots of sawdust up my snoot.
I'm going to try the stationary clamp method next time - I've got a box of the big ones around here somewhere.

What stationary clamp method?
David Ring's method (message 4). I should have spelled it "stationery".

I've got a 1HP Jet dust collector with what seems to be the same clamping method as you. I bought a clear plastic bag for it to see how full it is, but discovered a side benefit - it is lighter in weight and has a little more "body" or stiffness. It holds its shape reasonably well, so clamping it in place isn't a big deal. I put it around the metal lip and pull it tight from the front and fold the excess diameter over itself. Then I put the clamp in place starting in the front and feeding it around the back until it comes back to the front. Then I check that the bag hasn't slipped down and secure the clamp. It's much easier done than said.

Thank you all for your suggestions. I will give some of them a try and let you know what works best.

The problem I had was that the band did not behave like a loop until I used a small ty-wrap across the buckle... tighten it just enough to hold the band firmly behind the buckle when it is open, I fold the bag over the resulting loop(it would be lot easier if there were a lot more loops.. Ive thought of making more with ty-wraps but just did not get to it yet...

Good solution!
Anyone ever use a Goretex CleanStream upper bag?
Put one on a few years ago and it really cut the micro dust but I'm not sure it hasn't reduced the vaccum. (same size bag) It's on a 1.5 hp Powermatic. I think the floor sweep design robs most of the lift power on the big stuff. Powermatic stopped selling it. I'm looking at a 3hp Onieda pro if I can't modify the "up" channel (a box looking intake column supporting the business end) and dump the other collectors at the same time. My thoughts on modification lean toward installing a direct in-line 6" smooth metal duct from impeller to intake inside the column. Can't eliminate the column - it's what holds the unit up. Also eliminate the Y and go direct to 6" port.
Very strange, my 1.5 hp Delta has a spring steel ring that snaps into place on the inside of the housing. Just bend it back into an oval, shove it into the housing and release it into place. Adjust it to be sure it is seated and you are done. The pressure from the system keeps the bag and plasitic collector bag seated an in place. VERY simple.

Nice to see they finally figured out an easy system. Maybe I can retrofit mine. Thanks for the heads up.
I have the same collector (or at least it has cloth bags on top and bottom). The bottom bag in my case easily stays on (in fact it is a bit of a challenge to get on) before putting on the clamp. I wonder if you were give the wrong sized bag.
Mine is about an inch too big. Maybe I should try washing and drying it. If it shrinks the right amount, it might make it easier to work with. Before I try that, I am going to attach some magnets to the bag, as someone suggested, and see if that works.
I have the predecessor Powermatic dust collector with the same band strap problem. I refitted my top with the folded screen Dust Dawg filter, but use the heavy plastic catch bag on the lower half.
In my case, the supplied plastic bags are about 5" too short to rest on the base of the collector while I'm trying to attach the top. My solution was to build a 'false' plywood base inserted under the catch bag. Then I use a small brass wire brush to clean the banding area of the collector where the band strap retains the catch bag. The plastic catch bag is about 2" larger in diameter than the 17" collector collar. I tear about 4 or 5 pieces of duct tape to temporarily hold the plastic bag to the collector collar, and then tightly fold over the excess diameter plastic, sealing the overlap with more duct tape. Then it is relatively easy to affix the spring-loaded steel band to hold the plastic bag in place.
Give it a try. It worked out for me.
