MIMF

Maybe It's me, but there seems to be a growing interest in Dust Management these days so I'll be joining in.
I will either build a cyclone separator or buy one that will hook up to my Delta 50-580 DC. Currently the impeller sets vertically & the motor hangs off of it horizontally. My plan is to attach it to the top of the Cyclone so that the motor is vertical.
Does anyone see a problem with this in that the Bearings are now carrying the load in a different manner. I've seen this done several times with Harbor freight DC's, but not Delta's

I just did that with my Penn State dust collector. I never considered change in load on the bearings. I hope it doesn't cause a problem. If it does, I'll replace the bearings with better ones.

One thing that I gained from taking the collector apart and rebuilding it vertically on the cyclone was that it exposed the leaks in the fan housing. My shop is a lot cleaner now that I've caulked all the leaks I couldn't find before.

Hi Bob, I just got off of the phone with a friend & we talked about hanging the motor so that there is no weight on the impeller & supporting the impeller so that it doesn't pull on the motor.
This might just be more work than is necessary - maybe I'll just mount the motor as is & connect it with a piece of tubing.

How did you connect yours to the Cyclone ?

I'll try to remember to get you a picture tomorrow.

The motor shouldn't care but you might want to replace the factory bearings if they are noisy. All the bearings in my Grizzly motors are noisy but they're still turning after 20 years so I can't complain too much I guess.
Are you going with the larger Oneida Dust deputy?

According to some reading I've done some motors don't like being placed in that position. Contacting Delta Tech support was an exercise in futility.

How did you know I was looking at the Oneida Super Dust Deputy. I have access to the plans for the Bill Pentz system & purchased plans for the one from WoodCraft, http://www.woodcraft.com/Product/206022 ... -Plan.aspx

but after talking to people who have built cyclones - there is a lot of work involved & I would rather build Guitars.

Here's my converted rig. I used the plastic super dust deputy. I haven't figured out why, but the flow through the system did increase when I added the cyclone. Some of the finer dust still gets through the cyclone and into the bag, but the can collects a lot. There were leaks in the the fan housing and in all of the joints in the dust collector as it came from Penn State. The super dust deputy also required some caulk on its one joint. The filter in this picture is a 1 micron canister from Penn State. It was worth the expense. It also had a leak where the beater axle comes through the top. An o-ring took care of that.

Looking at that system, I see no reason why you wouldn't just mount the motor and blower horizontally like it's designed to be run, and just use a 90° elbow to join the blower to the cyclone/separator.; go oversize if you want to avoid losing flow volume, with the added bonus of the lowered velocity in the oversized elbow acting as another separator. You would even have the option of "hanging" the motor/blower from the ceiling.

Bob,
I don't know how important this is but I see an immediate conflict with your present system in that you are reversing the air's spin direction going from the dust deputy up to the impeller. I presume all your piping is 6"? That's a little hard to tell from the photo.

I spent a little time researching the vertical mounting and found that on larger motors at least there is a distinction. The vertical motors come with angular contact bearings. I would definitely recommend using this type of bearing if you upgrade the bearings. That said most small bearings are deep groove and can handle the axial load. All of this will be stipulated in the bearing's data. Note that angular contact bearings can only take the axial load to one side. You need to put them in the right way round.

Yes, the wind might get confused in my configuration, but it doesn't seem to affect the performance. That thing really sucks. The vertical plumbing is 6 inch matching the inlet on the fan and the connections on the cyclone. The other is 5 inch, again matching connections on the cyclone and filter. I went vertical to try to save some shop space. If I were building the shop again, I'd make it twice as big.

Here's another way to reconfigure a DC system. Ran across the link in a woodgears post.
