I know this must be covered somewhere but I can’t get the search engine to work. I am working on installing a Wynn Environmental filter (C1425C) onto my Delta 50-850. I decided to use the doughnut method as I am going to install a Thein baffle internally.

I am making the doughnuts and need to know what the inner diameter of the doughnut should be. Is it supposed to match the filter inner diameter?

Also I came across some posts saying that the cone diameter of the 50-850 is 11.5” which is supposed to be too large for the Thein baffle to work optimally. Some people have reduced the diameter down to the recommended 6-8”. I was wondering if this is necessary and if so how people have accomplished this.

Thanks and again sorry for repeating questions that have likely already been answered.

Thanks Rick. Could you possibly take a picture with the filter off so I can see the inner edge of the doughnut? I am confused by your PM. You said that once you cut the groove for the insulation you cut the hole “just under the size of the rim”. So does the inner doughnut edge extend past the rim or does it end before the rim?

Or maybe you mean just under the size of the rim of the filter! That makes more sense to me but I am unsure.

Also, I do not see the C-clamps in the pictures. Did you clamp it on the inside?

Sorry to be so dense…

Howard,

Sorry for the confusion…..My explanation may not have been very clear, as I was remembering off the top of my head…....lol…...Yes…..I’ll try to get you some pictures of how I cut the doughnut on top and bottom…..And yes, it is clamped on the inside to hold the doughnut to the rim….Hopefully the pictures will do a better job of explaning than I did…....

I have the Wynn filter on my HF dust collector.
The filter sits on the top of the ring and is held down with 3 small turn buckles that came with the filter.
Seems to be a air tight fit.
I do want to get a Thein baffle made or get the Super Dust deputy, so I am not cloging the filter up so much.

Thanks Rick, more pictures will be a help.

Thanks Steve, I am going for the doughnut style installation. The Delta 50-850 does not work so well with the turnbuckles according to Dick Wynn.

I used a C1425 on an old Jet DC1100 that didn’t play nice with the turnbuckles either.

The donut I created had a diameter just a little bigger than the inner diameter of the filter (maybe 1/2” or so). Reasoning was I didn’t want to create a lip for dust to land on. I suppose a diameter the same as the filter ID would have worked too. It worked fine for me that way.

To attach the filter to the donut, I just used screws and washers and the holes on the outside flange. I used some weather stripping between the filter and donut to get a good seal.

Keep in mind too, that the pictures that Rick showed are for the 35A. That’s different than the C1425 that you have. It’s got an inner flange for use with the turnbuckles.

gtbuzz, did you use only 1 donut or did you use 2? One as the “support donut” and the other to mount the filter on.

If you used 2, did the “support donut” sit flush to the lip of the DC or was there a gap? If there was a gap did you bother filling it with weather stipping?

One donut. Unfortunately I don’t have this DC anymore (upgraded to cyclone, but kept the filter), so I can’t provide pics, but i’ll do my best to try to explain. Also, the OD on the C1425 was smaller (maybe by about an inch or so) than the diameter of the tub on the DC1100.

  • Donut was made out of 3/4” ply
  • OD of donut was about 1” larger than the diameter of the tub
  • ID of the donut was about 1/4 – 1/2” less than the ID of the filter
  • On the underside of the donut, I created a groove where the outer diameter was pretty much the same as the diameter of the tub. Depth of the rabbet was 3/8” (half the thickness of the ply). If I remember correctly I used a 1/4” spiral bit and just made a trammel out of some scrap ply and a nail
  • There’s 4 screw holes on the C1425. Used a wood screw and washer to secure the filter to the donut
  • Between the donut and the filter, I used 3/8” foam weather stripping to provide an air-tight seal
  • Used the same weather stripping on the underside of the donut, but I also caulked the seam between the donut and the tub. It was probably overkill

Hope that helps.

Thanks, that really made things clear. I decided to go with the 2 donut method just because I know that if I try to route a groove in the bottom I will likely mess it up. So I was able to make the first donut ok. The only issue was that the trammel I made didn’t go below a 8” radius so the ID of the support ring was bigger than I wanted it to be. No big deal, the support donut is just put in so you can screw the donut that the filter sits on to the DC.

I go to make the 2nd donut. The OD ends up fine (about 1 inch overlap from the rim of the DC). I go to cut the inner diameter which I want to be 13 3/4 and again the trammel won’t go down far enough! I put on a 3/4 straight bit figuring this will give me some extra space, crank down the trammel as far as it goes and make the cut. Crap!! It ends up that the inner diameter is too big and filter will not be supported on it.

So I am going to have to make another donut but first I will need to make another trammel to cut the inner diameter. I will make a quick and dirty one this time.

Maybe I can use the messed up donut and circle to make a nice clock! I also have been thinking of make a disc sander since I have an extra 1hp motor so maybe I can use the circle as the disc.

IT LIVES!!!
I am happy to announce that after much head scratching, frustration and effort I finally got the Wynn Filter installed. I also made and installed an internal Thein Baffle. I hooked up the lower bag and the hose and then cleaned up all the saw dust I had made when making the donuts and baffle.

The Delta 50-850 works great! It has great suction and is also much quieter than I expected. Once I get the other dust ports, connectors, etc. that I ordered from peachtree I will complete the dust collection set up for my table saw. Then I am going to tackle the sliding mitre saw but I know this will again take some considerable effort.

My plan at the moment is to drag the hose from machine to machine as I need it but I can already tell that this is going to get old real fast. Now that I see that the DC has really good suction, I am starting to think about running 4” PVC around the shop and putting dedicated dust lines on the major tools.

Thanks for all your help and advice w.r.t. installing the Wynn Filter. I really appreciate it.

If you email the folks at Wynn, they are REALLY nice and eager to give help on this type of thing. Tell them Stumpy Nubs sent you and you may even get a free cup of coffee.

Hey Stumpy, I did speak to Dick Wynn during this process and not only helped me choose which filter I should buy but also gave me some great advice on how to install it. I would have been more stressed had I not talked to him.

Everything is installed and working great.
