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' ?
😊😊😊😊😊😊😊😊
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.
@@davidelliott5843Man 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.
I said it once and I say it again: Continue like this and one day you'll score a job at NASA, building spacecrafts. Absolutely brilliant work.
NASA has you grind off any mill scale when welding...
@@jeffallen3382 i doubt they grind it off by hand.
Or do you weld for nasa?
@@bushratbeachbum it doesn't matter what they use... They don't weld over mill scale! My old buddy use to weld for NASA.
Also doesn't matter who you weld for. You weld over mill scale and you will fail any kind of certification testing. Doesn't matter if you're a pipe welder or work for NASA.
@@jeffallen3382 Jer is young. He will improve over time. No master was born as such. 5% talent and 95% continues training.
@@caigner LOL
“We don’t know what 3phase is in the US” gave me a good chuckle. Good seeing you on camera again.
My first job in Brazil was to make these snail exhaust fans and air recirculators for gas ovens for curing powder paint.
I love the the squiggly seal, efficient and good looking!
Always amazed at the carefulness and attention to detail you put in a project. Awesome video once again!
So good to have you back mate! Was super happy to see the jer notification
I get the same joyous feeling watching you(r videos) as I get watching Lionel Messi playing soccer!
For those not in the knowing; one of the best players ever to walk the pitch.
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.
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.
glad your back been missing ya
I'm from Ukraine, I've been watching your work for a long time, I want to thank you for the accuracy, honest attitude to work, I'm a teacher of labor, wood, metal, I'm older than you, but you teach me, THANK YOU!!!! SORRY FOR MY BAD ENGLISH.
вітаю🇺🇦
I like your thinking on the wiggly bits, and love when what looks like decoration is actually functional industrial design.
Wow, that Leeson motor is a beast.
Dude, thanks for showing us your process. Have a nice day.
DAMN this UA-cam algorithm! I didn't see that you're back! We missed you
Excellent work!!! As having been a torque wrench specialist.......you have to hold the torque wrench by the handle.....otherwise you are not achieving the appropriate torque that was set on the torque wrench.
Rocket science :-) Amazing !!! Everything looks easy ... but it's not. The detail is not (never) an option with you !!! Bravo !!!
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?
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.
Hopefully as the blower is upstream of the cyclone there should not be any large pieces reaching it
@@Jer_Schmidt 1/4" Hardware cloth fencing is good, provides a stiff backer.
I have a Delta 50-179 that has a plastic impeller that all the wood travels through. It has lasted 32 years.
@@onjofilms
Whoa I would not have expected that. 🤯 Good to know!
Can‘t wait to see the last video … it‘s always a joy to see you working … I like the way you find solutions for the process and the result is outstanding. Thx for sharing
great use of maths and geometry designing your parts. you're smart in finding solutions
JEREMYYYYYYYYY, I love your videos more than any other content creator on this platform, nice hairstyle you're rocking!
Appreciate you and love ❤❤❤
Yes, the fine kreg screws are excellent for Not splitting. Great work Jer, as usual. Please send rain !!
Nice job. That impeller should last a lifetime.
You seem a lot happier now. I like your new content even more then I liked the old.
GLAD TO SEE YOU BACK TO BUILDING THINGS. I'V ALWAYS ENJOYED SEEING WHAT YOU COME UP WITH NEXT. KEEP IT UP.
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.
Glad to see you posting videos again. Welcome back
If you're really concerned about those bolts staying in place, i would consider adding lock wire. It's not a lot of extra effort, but it's a lot of extra insurance.
I seriously considered it! But I was concerned about the wire sagging, touching the impeller, and throwing a spark. (That’s also the concern of the bolts come loose. Nothing will fall apart right away, but it could start a fire in the filters)
Just threadlock them. Use the red one. It's easy enough to get them out again with a little bit of heat
@@Jer_Schmidt There's still tab washers to consider if the problem presents.
@@Jer_Schmidt man, nordlocks!
I love how everyone building something looks at the numbers on their test meters and says something along the lines of "it's using a bit more "
It’s also very possible that it won’t be fine haha. Cyclones create a LOT of resistance, so I think it’ll be enough to pull the amps down from 24 to 20, but if not, I’ll grind a bit off the ends of the blades.
So beautifully designed and executed. that thing’s a piece of art
I'm a week late, but I'm so excited to see another video by you! ♥
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.
Good to see you back
I’ve missed you on UA-cam. It’s great to see you back. I hope to see more of your work as time goes by. Thanks for some interesting, educational videos.
Nice job.
I find it ironic that people are upset that you'd show electrical work when - last I knew - one could find at least 30 videos showing how to illegally back-feed a generator through a dryer outlet.
Then there are the newer ones showing "clever welding tricks" like "slugging" and "snot tacking".
Subbed
So nice to see someone with natural feeling for geometry at work. Making smart use of stuff available.
As usual magnificent engineering and execution
Very inspired by your attention to detail and the amount of care you put into your projects!
Excellent progress. I’m so looking forward to the next instalment.
Just awesome so far. Can’t wait for the final outcome! Nice work!
Your skill level and attention to detail is phenomenal. I’m looking forward to seeing the fun part when you put it all together.
So glad to see you back - great build as always.
Once again you impress us regular thinking guys!
Another build that is outstandingly detailed, well thought out, and an excellent example of fine craftsmanship! Great job, Jeremy!
Just gorgeous fabrication. Loving the efficient use of materials and accessible tools. So good to see you back in action.
Love it. Always enjoy your work. Can't wait to see the rest of the build.
Great work Jer, its coming right along.
Thanks for sharing.
I love the aesthetics, Jer! Great to see you back creating, and sharing it with us. Hope you're keeping well.
Can't wait to see the whole thing assembled.
Amazing build quality! So glad to have you back making content.
You're on another level, that's for sure. Kudos from Brazil.
Nice job Jeremy glad your back in the shop again.
Thanks for another great video! I remain impressed with your problem solving skills and your thrift is most definitely appreciated. Keep up the excellence!
I wish I had friends like you
Jer - Its good to see you making videos again. I hope all is well in your world and, as always, your work is perfection!
Good to see you back with another amazing build.
Jer, incredible engineering as always. I love you narrating the details. Explanations. Fantastic.
Amazing as usual Jer absolutely great work loving your new workshop
Each little section is a project of perfection in itself - and then you put them all together into a serious tool! Very impressive work!
Nicely done, Jer. Glad you're back!
Excellent job Jeremy!!!
I’ll say it again. Totally amazed with your problem solving/solutions to your build process. Truly impressive!
I really love that you are back posting more regularly, I have been watching for years and still drop everything when I see a new video from you! Thanks you for making such great videos
This is going to be one hell of a system! Looking forward to the next video.
Nice work, as usual. I think it's cool you're using only clear finishes for both the wood and the steel.
Love your video style, length, level of detail. I'm so pleased you're back posting, even if it's less frequently
So glad you're back, man! I really enjoy your videos!
I love watching your jigs and setup work. The real secret sauce.
Glad to see you're still making videos! You're one of my favorite creators. Keep it up!
Great work Jer. Nice to see you and your videos. You are a brilliant person.
Jer, it's really coming together! Heavy metal is just all right with me! 👍👍
A nice little project but sometimes what I find most interesting is the simple and effective way you develop fabrication methods to accomplish the build, Bravo.
I am in my 50's and I have been fabricating things since the late 1970's ... your skills and methods are impressive!!
I always enjoy watching you work. Interesting, informative, and impressive. Thanks!
I am just sorry I cannot give two likes to this video! Excellent work!
As with part 1, you are a gifted maker. Love watching what you accomplish! Thanks for sharing with us all. Great stuff!
Has to be one of the best builds I've ever seen, well done!
Nice to see you Back Jer. Keep the Videos coming and ill keep watching.. you are Fascinating sir!!
You are an absolute genius!!!! Love your content! Glad you are back
This is such a clean build. Very well done. 👏 I love the look of the wiggly sections. Form from function at its finest!
A work of art, Jer, very good looking
Glad to see you 'back on the horse' and working on projects again. All the best from Australia, looking forward to the rest of this project.
A neat and lovely build! Thanks for sharing.
Fantastic build dude. A really professional look about it. I am so glad to see you back on here mate it was so long since you made a video prior to these. Great video buddy 😉👍🏻👍🏻
Thank you. Your efforts are a pleasure to watch
Amazing attention to detail. Superb job
Awesome work young man! Cheers, William
Good to see you back. This is a great build. Be well
Clint
Glad to see you back. 👍. Your videos always provide inspiration and demonstrate problem solving I can apply on other projects even if I'm not building the same things. Thanks for all you do
Awesome as always! Really enjoy watching you work, always lots of clever ideas and genius jigs. Looking forward to the next, but take your time. We'll be here! Thanks for sharing!
Excellent video. You've leveled up since coming back!
Found you by accident, you are very good, thanks for sharing these nice techniques, I've learned a lot!
I'm always amazed at how smart you are and how interesting you're able to make your videos. Thanks,
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.
i really enjoyed watching your thinking process during this project. You're a wonderfully talented and kind man. Thank you!
Great work Jeremy, very impressed.
Sweet grinder, I have one just like it:) funny story, I sold the welding table that I have my grinder in. One of the people responded to my ad, “hey is that a Jeremy Schmidt grinder?!”
Fantastic build Jeremy! Your attention to detail and execution is amazing! Looking forward to Part 3 of this build. Be well..... 👍👍
