Using a CT22 vertically? and a few other questions about it...

[Toller]

I just bought a used CT22 ($250) and have a couple questions.

1) I want to put a Onieda Dust Deputy (separator) before it.  The only way to avoid some hard angles and a lot of extra hose is to mount the CT22 above the dust deputy with the hose of the CT22 pointing straight down.  Any reason that wouldn't work?  There will be almost nothing coming though, if past experience is any guide; the separator is very effective with little suction loss.
2) Since there will be almost nothing but really fine stuff, maybe I could just take the bag out and just use the final filter?  Would that make it suck better? Other then possibly clogging before it should (which I can find out by trying it)  is there any reason not to try it that way?
3) Is there any advantage to running a 2.25" hose from the dust deputy to the CT22?  it will only be a couple feet long and carry only fines.
4) The CT22 won't be where I will be plugging tools in.  Can I run an extension cord from the CT22 outlet to an electrical outlet(connecting the end of the extension cord to the receptacles in an electrical box), plug the tools into the electrical outlet, and have the CT22 work on automatic?  Any alternate ways to make this work?

As I recall, when the CT-22 is sitting normally, the internal fittings initally run horizontal, and then make a right angle down into the bag.

If the CT-22 is mounted in the hose down position described, the right angle of the fitting may prevent some of the debris from falling back down. 

You will most likely lose efficiency as the bag fills.  In effect, you will be attempting to blow dust into the bottom of the debris pile.

The Auto-Trigger of the CT-22 only works if the tool is plugged into the power outlet located ON the CT-22's case.

I hope this helps,

There is no problem having an extension cord between the two.  Just be sure it is not waaaaay too long for the task.

Ah, I misunderstood the question.

Thanks Corwin,

My question about this is:  Why do you want to tip the CT 22 and put it on top of the cyclone?

Are you trying to save floor space?  If you are short of floor space, as I am in my own shop, you must need every inch of space you can get in the areas within the plane of your working level (bench top, TableSaw, BandSaw, etc) also.  To raise the CT above bench levels severely limits that valuable air space.

I have my CT 33 hooked up to a 5gal paint bucket.  I have the boom between the CT and the bucket with cyclone top.  The hose from cyclone (along boom) to tool is 5m instead of 3.5m.  this gives me some flexibility to move the cyclone around and out of the way for some operations.  For the most part, I think I lose much less space by keeping the whole dust cleaning operation below table (MFT) level than I would lose by putting the CT, or the cyclone higher than table top.

I recognize your problems are certainly different than mine, but I am sure that any of us who are blessed with very minimal space are open to any suggestions, and this is my personal solution

Because i am desparately short of floor space, but have space directly above the separator.  That might not make sense in your shop, but it is how mine is set up.  So my choice is having the CT22 horizontal with a long hose running in a big loop between the two, or vertically, with a short hose running directly between the two.

Toller,
Don't take me wrong.  I was not knocking your idea. Just comparing ideas.

I would gladly swap some of my floorspace for some of your overhead space.  Come to think of it, not much of a swap as my extra floor space is almost non existant.  My overhead space and wall space is even worse. I am building some tool storage boxes to store overhead between ceiling rafters.  I would like to figure some sort of a switch on your method with a way to pancake a cyclone so i could store that between overhead joists.  :-\

One way could be to cut a hole in the floor above.  It would be right in the middle of the BOSS's sewing room.  with a little immagination, i could make it into a very comfortable seat for her when she is working there.  Oh well, it has been a great life.

I think you are overestimating the suction loss due to hose bends and length. The CT22 is a positive displacement vacuum, unlike a impeller based DC system where smooth airflow and volume are the name of the game. If you mount the CT as you describe you are essentially making it a stationary tool. I think that is a waste of a good system. I would buy the quietest cheap vacuum I could find if I was going to dedicate it as you have. In fact, I have a mini-cyclone that is hooked to a Rigid vac that has a silencer on the exit. I generally detest the thing but the cyclone makes it far more useful. I also installed a HEPA filter in it for clean air purposes. Whatever you decide, I would not remove the bag. It eliminates the inevitable cleaning you would need to do, especially if you overfill the cyclone. Murpy's Law, you know. My Rigid has no bag, which means that without the cyclone the HEPA filter blinds off long before the darn thing has collected any significant debris. OTOH, I just vacuumed my garage with the CT22 whose bag was almost full before I started. I hadn't done it for a year and expected the bag to be full in about 2 minutes. Not so. I did the whole floor thinking, "That bag has got to be full by now." I was just beginning to feel that suction was deteriorating when I finished. I put a new bag in for grins a ran it a little more just to see if the suction improved. It did, about 5% I would guess.

My point really is that airflow in a positive displacement system just seems to be less effected by corners and bends. Try to keep your set-up symple and versatile. Maybe park the vacuum under your cyclone so you can disconnect it and use it elsewhere when the need arises.

Toller,

I don't know if I fully understand your proposed setup, but I recently got a Dust Deputy (full unit with metal can) and a couple of adapters from Oneida.  At first I hooked the outlet of the Dust Deputy to my Fein Turbo II vac using a short section of standard 2 1/2 inch hose from my ancient Craftsman shop vac.  That proved to be a mistake because when I temporarily blocked the inlet hose, the Craftsman hose coils shortened up and flipped the DDeputy on its side, crashing into another tool on its way down.  I substituted the short length of 50 mm hose that comes with the boom arm, and no more of such problem.  For most work, I am using a Festool 36 mm hose on the inlet for the DDeputy that also has a jerry-rigged adapter and Fenco rubber fitting to accept the standard vac-end fitting of Festool's hoses.  I wrapped a few turns of electricians vinyl tape around tool end fitting of the 36 mm hose, so I can quickly add/remove the length of Festool 27 mm hose that i use with my Deltex 93 and other sanders.  The DDeputy does not filter out long, fine splinters of wood such as are created when sawing a hair off cabinet grade veneered plywood.  I usually find these caught in the outlet of the DDeputy.
