Building a Blower (DIY dust collector part 2)

[@BillPentz]

Hi this is Bill Pentz. Most of your cyclone and blower are evolved from my designs that I have been refining since 1994. You have done a pretty good job, but there are a few things that you need to consider for safety and ability of people with lesser metal and woodworking skills to be able to build your units. 1) the 1/4" plate is heavy but is the right stuff to use for your impeller base. 1/8" plate will warp all over unless you have a very fine welder and good heat sink. 2) Your noise levels at over 100 dB were not unexpected but can be greatly reduced with a few minor changes. a) You really do need to be using backward inclined blades. If you divide your blower into six equal pie shaped wedges, then you should offset your blades 2.5" from those division lines to create backward inclined blades. Backward inclined and your already backward curved blades make a huge difference in blower noise. b) You also need to sharpen your blower gore point instead of a gradual curved bend and add a second matching gore point on the inside outer portion of your blower to create a noise canceling effect. Sharpening gives you better performance and a level of noise that can be canceled. c) Also, I chose to weld on both sides of my impeller blades. If you just weld on one side, it should be the blade backs to reduce turbulence to also help with noise. 3) Your cyclone and mine are identical except I continue the cylinder up instead of just closing off with the air ramp. Many are poorly copying my design both ways now. The advantage of coming up is you save having to add a duct piece on the front of your blower and can just make a 9" diameter hole. You need that same sized duct coming out of your cyclone if you want optimum separation and airflow for an 18" diameter cyclone. 4) I found bolting the motor directly to the Baltic Birch plywood and using Loc-tite holds up for a while, but eventually vibrations cause the Baltic Birch to fail. I shifted over to using a steel motor mounting plate that I hold in place similar to how you hold your blower intake duct. 5) I found having my blower base and blades laser cut costs little and greatly minimized balancing. Also, I made my base have a tight fit to the compression bushing arbor which reduced runout and made for a smoother less wobbly impeller. 6) I also tried mounting the metal blower sides to the Baltic Birch. Turns out they will eventually develop openings from being banged hard by debris when you forget to empty your collection bin. A better technique is to make the blower larger in diameter, securing with carriage bolts outside of the metal which rests in 1/8" deep grooves in the Baltic Birch. 7) You can buy ducting flanges in the diameter you want that have a flared base and foam insulation making it far easier to install than the complex hole. 8) Many will want to make their cyclone and blower parts from galvanized steel. Galvanized reacts with silicone to break down and lose its seal. You might instead want to use a good gutter sealant. 9) you can take your identical sized blower vanes and move them out on the same sized base to create a larger overhang and 16" total diameter impeller. I found with these 4" tall blades, that is the ideal size to use your motor full capacity without risking burnout from moving too much air. 10) Please don't ever turn on a newly made impeller that is not encaged in a blower housing. One of my buddies started making impellers for me and he had bad welds. A blade broke loose and destroyed the blower housing plus the whole rest of the impeller before I could kill power!

@BillPentz What exactly do you mean by: 'a second matching gore point on the inside outer portion of your blower' ?

[@luisbarreto7019]

😊😊😊😊😊😊😊😊

[@BillPentz]

@@E_L12 If you look at the blower housing the outlet has one side that merges into the decreasing blower spiral. On the other side there is a sharp 90+ degree bend. That sharp bend is known by many as the gore point. Much of the blower noise is created when the exiting air hits this sharp bend. If you took a dowel nearly as tall as the outlet sides, cut the dowel in half lengthwise making a half cylinder, and mounted that on a stick where you could slide it in and out on the smooth side of the outlet, you would find a spot where the noise it makes comes close to canceling the noise from the gore point. Between changing the blade angles and installing a second artificial gore point you should cut overall noise to as low as one quarter as much. Gluing neoprene to the blower sides, top and bottom will help even more. If you use insulated ducting for your outlet that will quiet the noise even more. Would you send me an email? [e-mail]

I know your struggles on the back side, it’s something I go through. glad to see you making progress and getting another build up. Take your time we will wait .

20 years ago, a chiropractor got me through an L5-S1 disc prolapse. He said I was so close to emergency surgery that he expected to be calling ambulance when I arrived. It was never needed. Results were was so impressive that I did the training. That all said, sacro-iliac joint pain is often diagnosed as disc or sciatic. Chiro is very good with SI joints. Getting them balanced takes load off the discs and facets. Win win.

[@matthewmoilanen787]

​@@Dave5843-d9mMan I wish I had a Dr like that willing to operate with just one ruptured disc. I just had my second surgery to take care of the second disc replacement and L3-5 fused to the already fused L1-2. In addition they removed a 10 mm cist from my spinal cord only to find an SI joint tear. Unfortunately no form of therapy or rehab had any effect so it required fusion as well. It's a miserable thing to go through and I wouldn't wish it on my worst enemy.

[@TheHermeynator]

Always amazed at the carefulness and attention to detail you put in a project. Awesome video once again!

[@josuelservin]

I love the the squiggly seal, efficient and good looking!

[@MariusHornberger]

Great build. No doubt, a better blower than my one. I like the idea of bolting the housing to the motor and having the opening for installing the impeller on the bottom. Makes more sense now that I think about it. Do you want to install an inlet screen to protect the blower from large pieces?

[@Jer_Schmidt]

Thanks! I thought the bottom opening for especially made sense since I’ll be connecting the cyclone with a big piece of flex hose. I actually completely forgot about putting a screen in it, I was going to do that. Might add it yet.

[@SudburyDave]

Hopefully as the blower is upstream of the cyclone there should not be any large pieces reaching it

[@benjaminreinhardt259]

Awesome work. As far as butt welding sheet metal - you want to stack tacks. Tack every 2", then come back and put a tack on each tack. That will move your heat around and minimize distortion. Also prevents blowing holes in the the metal. Other than that, awesome work buddy. Leagues ahead of me.

[@JBLewis]

Ron Covell just posted a video the other day butt welding strips of metal (copper) and finishing them to the point that the welds all but disappear.

[@zendesigner]

great use of maths and geometry designing your parts. you're smart in finding solutions

[@alans1816]

Your cyclone and blower look like they will last forever and work extremely well. They far outclass the ones I made. You can take as much time as you like and I will always be happy to see a new video from you. This was not a long wait.

[@kancelas]

Glad to see you posting videos again. Welcome back

[@hdwoodshop]

Never cease to be impressed by your sound thought process. Amazing engineering and inventor mix. I’d be curious by a financial breakdown of your final assembly.

[@Jack-yl7cc]

Normal household Silicone sealer is a bit too soft to stand up to basically being "Sandblasted" for very long but, on the flip side I am sure the same joints would eventually get packed with saw dust anyway so it only has to last long enough for that to happen. For future (re)builds I would recommend some good quality automotive seam sealer like "SEM 29372 Gray Seam Sealer". The nice bonus part about the SEM tubes is that the nozzles screw on, which makes unclogging them or even replacing them entirely so much easier. The downside to SEM sealant is that its too good at being impermeable so it takes some specialized paint to get it to stick to it.

[@ckutzli]

Nice job Jeremy glad your back in the shop again.

[@RamsesTorresLifevantageIndDist]

Beautiful design. Glad to see you creating again. For welding thin metal try series of spot welds, cooling with shop air between passes, instead of continuous bead. Very thin gap will allow good penetration. Loved the rabbet detail so sheet metal would be flush and help alignment.

[@kevinpettigrew4792]

DAMN this KZbin algorithm! I didn't see that you're back! We missed you

[@MetalAsFork]

I'm just 13 mins in, and don't really do any work like this, but it's really impressive how resourceful and creative you are with repurposing shop items. Using the drill press stand as a mandrel, or the drill bit as a router guide, testing the screws in the plywood... It's not so much about the specific tips, or how to build this exact item, but the philosophy of being adaptable in completing a task. Fun to watch.

[@scottwhite2379]

Great to see more videos in my feed. Glad your doing well. A tip, when butwelding sheet metal, when you can. Support the back with copper. No melt through, traps the gas, and weld won't stick.
