It's nice to see that there are still guys that take such a good care of their wife's toothbrushes. To spend the whole afternoon cleaning it... incredible dedication to your wife's well being.
Your comment of tighter than a bull aXX during fly season brought back memories of my old shop teacher from 50+ years ago {SMILES} ! Thanks for the memory !
It’s funny, how motors are different now from years ago. I work electrical maintenance and have for twenty years. The sleeve bearing motors run for sixty plus years for the most part and dirty or not just keep chugging along. The new replacement motors with ball bearings usually last five to ten years. You just have to love progress and how much better made equipment is today. (A little sarcasm there). Keep up the good work Mr. Pete
Great video Mr Pete, My grandpa taught me how to Rebuild motors like this when I was 9 or so, remember it to this day, I just rebuilt a 20 Hp 3 phase Blower motor for the A/C unit at work, a new motor was 3700 bucks, all it needed was New bearings that I heated up and Installed, they shrunk back to the shaft, it Runs like new now, VFD's are hard on motor bearings, Only cost me 60 bucks and a few hrs of time, My christmas bonus should be nice this year!!! Repair dont replace!!! thanks for the Great video Mr Pete
Near as I can tell its because the wildly different Frequencies that VFD's use to control the speed of the motor, some of the Frequencies make electricity escape the squirrel cage and want to make it to "ground" so they cause micro arcs and Pitting in the bearings, The engineers factored in 60 herts for longevity but when VFD's came about it induced some different parameters than they had considered, look what happens to Slip rings or armatures and they arent even load bearing. Ive also researched that the slower speeds cause Issues
not entirely sure the science behind it but Logically it makes sense, and Real world, we have a 7.5 Hp Kitchen exhaust fan that is just direct on or off 480V 3 phase 60 HZ one speed and in 3 years it has not even so much as eaten a belt but it runs 24/7 365, Everything I have that is VFD drive goes through belts and bearings every 6 months, You know what they say, things in steady state are fine, Its the change of state that causes issues, so going from slow to fast or Vice versa and imparting strange parameters tells me that may be a part of the problem
Hi Mr Pete a really edutaining and informative video thanks for posting it. My dad gave me a Crescent wrench when I started work in 1972 , I am close to retiring and it still works as good as the day he gave it me, my dad passed a good few years ago but each time I use it I say " thanks dad" Cheers from England
"Edutainment." Kind of like "anticipointment." (The anticipation of a "new" product, and the aftermath of the same.) Yet another GREAT video by Tubalcain! steve
I enjoyed that. Especially, the part about the bull's hind end. LOL! I've torn a lot of motors apart for the copper in my younger days but, I never realized, how little clearance there is between the stator and rotor.
Bean counter's and their ideas for planned obsolescence infuriate and are just wasteful . I like your idea for position marking during disassembly of the motor, I will be using that one for sure. Please keep up the great work and thank you for sharing Sir. You are my favorite shop teacher.
I too, worked at a motor repair shop back in the late 60's. Did yours have one of those trichloroethylene spray down baths? You'd put the whole motor frame into it and use a spray hose to flush all the gunk out of it. It did an impressive job and the repairman then had a clean motor to work on. It had a water cooling jacket to keep the solvent condensing back into the bath. The cloud of solvent just hung in the bath and there was a metal cover on it when not being used.
I took to doing the same kind of position marking on car and truck hoods, when they needed to come off for pulling the engines. I bought an old Buffalo Forge drill press that had a "burned up motor," according to the seller. It has an old G.E. 2 hp three phase. Turned out it was the bearings on it, and getting it knocked apart was a real challenge. No real damage to the bearings or shaft, I can only assume that when it got hot, it caused the bearing material to get hot enough to swell or upset. A light polish of the shaft and honing of the bearings was all it took to make it work again.
Nice clean up on a usable machine. Remember, these were never intended to be top-line tools. The lower end were made to be used on a job and thrown away. Dayton is the Grainger house brand (they bought the old Dayton company lock, stock, and nameplate back in the 1960's).
Great video! Yes, there are lots of us that would like to see a belt sander build. I would like to see you build a carriage lock for a 10" Logan lathe. I can buy one for 75.00, but would love to do another of your projects along with your instructions, (and rants)! I made your toolmaker vise, and your clamps.
I forgot to add my bull reference to your funny remark about blowfly season. I've heard my Granddad describe a sloppy or screwed up job, as looking like "a bull's butt sewed up with a trace chain".
Mrpete actually sold something! Amazing. The carriage lock is a 1/2" bolt head top right on the carriage next to the tool post. Maybe it's a carriage stop he wants.
Thanks for the education Mr. Pete, I didn't know a centrifugal switch was making that noise in the motors with capacitors. You could give a more in depth talk about that type of motor. I would appreciate it. Thanks again.
enjoyed the discussion/cleanup/education.....just so you know I paid attention in class...you put the 4 end bolts in reverse of when you took it apart, nuts were on the cord side...hope I get a passing grade this grading period.....lol
Being one of those "Hammer and Chisel Mechanics" you always talk about, I learned something new watching tonight, I can use a screw driver too. LOL Great Vid as always !
Great video, Mr Pete! I enjoyed it very much! As for your talking too much, when a person gets to be our age, who cares! I worked for a while in a electric rewinding shop. Most of the motors we worked on were as big as a mini van. Blower motors from the coal mines in WVA. I also really enjoyed your videos on the Clausing mill. I have a #2 Cincinnati horizontal mill I'm refurbishing. Thanks for all you do. Chuck
"...tighter than a bull's hind end in blowfly season!" LMAO!! Amazing what a 'reputable' manufacturer will do to save a buck. This is what has happened as the bean counters have been allowed to take over...by management weasels that get paid way too much and can't remember the last time their hands got dirty! Great price (more or less), but a maintenance nightmare. Thanks for another fine video! :-)
Hi Mr Pete very informative and interesting your story's are so great . I really enjoyed watching repair of machinery you do it so well . Thanks for sharing best regards Shaun from a cold but sunny morning in South England 😀😀
Mr. Pete scolding Dayton, classic, gotta love it!! In the past I have installed toggle switches in the middle of the motor electrical cover plate (if there is room). I agree McDonalds has really good and inexpensive ($1 any size) coffee. I went to Dunkin Donuts yesterday and the same size coffee was $2.50 (and not as flavorful)… Carpe Diem Mr Pete!!!
Nicely done Mr. Pete and you called it ahead of time when you spoke about the motors with the open bells sucking in the debris. Definitely not a good design.
So long as its only dust getting in the motor ,in ozzi we have hornets that FILL ANY HOLE they find with MUD They will fill the bell ends of motors too ,its necessary to cover with mesh and fill holes with foam. Cheers lyle keep on keeping on.
Next! I would put a shield below the work table to help deflect grinding debris from entering the motor. A foam filter such as is used in lawn mowers could also be put in front of the intake ports. Handy machine. It should be a TEFC motor of course.
A 'pie plate-like' shield between the housing and the wheel would seem to get you 90% of the way to preventing the reoccurrence. Can't close off the airflow, but it seems like munging it so the grit at least can't fall/be drawn in -directly- through the exposed holes would be simple, quick, and thus worthwhile.
This could also be the cause of motor "seizures" on so many cheap, household fans..... Brilliant examination! Those cheap fans could also suffer from the trigger of an overheat-prevention switch/fuse.....???
I think you can adjust the platen with the two bolts that hold it on the horizontal base. It looks crooked there , and it looks to have been welded in a spot that may have cracked $$$ the reason it's not tracking I'd bet it was dropped or something. Thanks Lyle for another great video.
Add a metal box with a switch, just cut the cord! Box can just lay on table next to sander. I have a Rockwell band saw that gets dust in the starting mechanism, and I have disassembled several times to clean out the dirt. I finally took a cloth and duct tape to cover the air intake on the motor. Works well, no more dirt in the motor. -Todd
High respect and thanks for educating us. I would suggest you vaccuum and wipe the outside with a damp towel. Reduce talking and hepa vac the inside vs talking. Just not healthy and it is extremely important for all of us watching and learning.
Please keep on rambling!!! Sometimes the most obvious things you work with every day don't sink in and get thought of until some one points them out. I have a Delta wood band saw I bought new about 30 years ago. I do clean it off when I am in that mode of cleaning up the shop. But usually it has 1/2 inch of saw dust all over it. I just looked and it also is an open motor. I can just imagine the amount off wood dust that has gone though it over the years????
Remember crescent wrenches are for metric bolts only and West Virginia fits all AR for SAE bolts I don't think there's a way to use a adjustable wrench wrong keep up the good videos thank you
"Tighter than a ..." Something not many people would know but I can relate to it. 😄 Wonder if the tracking would improve if you moved the motor's pulley in (toward the motor) a bit? Is there a way to add a small shield for the motor's intake?
Some motor shops had a dunk tank that they would simply dip the whole motor in without disassembly and it would flush out the debris- dead simple, I think it was carbon tetrachloride or some such mystery chemical. Typical clearance between rotor and stator is (was) on the order of 10- 12 thou, the tighter the tolerance the better performance and efficiency, but then the risk of rotor knock rises too as it flexes under load.
Hey Mr. Pete! I have a 2x72 belt grinder very similar to yours with a 3/4 hp I have too much side to side (end play? ) How to I go about repairing this?
I saw a guy in high school shop class who was making a chisel put it against the belt (point upwards) of one of those vertical Kalamazoo. It caught on the seam, flipped it around, and drove it into his stomach. He had to have surgery on some internal organ or two.
I think back to some of the machinery we were using in wood and metal shop (table saws without guards, lathes, torches, etc) with no safety training or even much training at all, and I'm amazed. Also, we were idiots to begin with.
Throughout life there are people who made their mark on your life, never to be forgotten, so we can perhaps pass it on to someone else. This is what God intended.
When I saw you open up the motor, I Mrs. P's toothbrush was going to take a beating! Your purpose is to "edutain" I have heard that someplace before? Thanks Lyle
You might consider installing a sheet metal shield between the case of the motor and where you do the sanding so that the air being drawn through the motor is from the left of the shield (as you're facing the machine) and not through the area where the sanding grit/metal particles are falling. It might prolong the working time between cleanings. Of course you know I live down south and in my time working with guys "born and bred" down south I've heard many a colorful saying used by said men. The funniest one I have ever heard was; " I'm so hungry, I could eat a keg full of wiggling a**holes."
That's quite an expression, never heard of that one. I bet you heard plenty in the Navy. In an upcoming video where I build a belt sander, the very nature of the design provides a shield
Mr. Pete. Are you sure it was Oak Leaves that made you so "hyper" the other day ? I begin to suspect it was Macky Dee's coffee. There does not appear to be any camber on those wheels. Correct me if I am wrong please.
TEFC motors are of course much more expensive because they need to be constructed from materials which will tolerate the excessive heat that results from intentionally failing to properly cool them.
You definitely have different McDonald's in your neck of the woods 'cause our two here have undrinkable coffee. Matter of fact, it's a topic of group conversation quite often. Used to be the best coffee going.
What a mess! Agreed! That's the wrong motor for that application. Any motor on a power tool needs to be a closed design! If the tool is designed to remove material in anyway (Sanders, saws, drills, etc) why in the world would you have a fan sucking in all that debri and blow it into its core? It's designed to last just as long as it's warranty... They don't want it lasting 25 years, they want you to buy a new one every few years.
Are you talking about Charbucks? The only reason that chain survives is because they in the beginning they build near colleges. Millions of students got their first taste of coffee from them and now think coffee is supposed to taste like it was burned and have the taste of cigarette smoke.
In regards to your using the wife's toothbrush, how do you know she isn't using yours to clean the toilet then replacing it back in the holder? LOL The shims on the shaft are also sometimes used to ensure the rotor is properly positioned to ensure the rotor runs at its magnetic center thus reducing thrust and current draw.
I'm from Seattle and can't stand that "brand" of coffee either. There are two other coffee companies based there and their product is much better. But I'm with you, the senior discount Mickey D's coffee is a good bargain and tastes pretty good to boot. I have a Dayton bench grinder that is making a racket. It's time to do a bearing job on that machine.
It's nice to see that there are still guys that take such a good care of their wife's toothbrushes.
To spend the whole afternoon cleaning it... incredible dedication to your wife's well being.
lol
Best teacher online. Thanks Mr. Pete.
Thank you very much
When it comes to "Edutainment" Mr. Pete, you are the Jackie Gleason of RUclips shop videos!
And awaaaaaay we go!
Nice repair on the belt sander. The part of the video I liked best was you talking about the folks you have met and worked with. Very interesting.
Thanks Harold
Stator and rotor - AC motor. Field and armature - DC motor.
As an aside great video. I really enjoy watching your videos as I always learn something.
Thanks
@Timothy LaPlante the field can be a permanent magnet or an electro magnet. It would depend on the type of DC motor.
Your comment of tighter than a bull aXX during fly season brought back memories of my old shop teacher from 50+ years ago {SMILES} ! Thanks for the memory !
lol
Dealing with a dirty motor myself. Good video Mrpete. Thumbs up.
Hi Steve. I just watched your video, wow what is that motor filthy inside. Lot worse then mine. But mine was locked up
As always, Mr Pete, you crack me up, and I learn a lot. Please never change, you're the best!
I learn something new every time I watch one of your videos. Thank you sir for the great content.
Wow Mr Pete, the McDonalds coffee must have been hi-test, you were really buzzing through it! 😉😀
Mr Pete on a coffee rant over a motor that was built 50 years ago. I don't think they can be shamed - probably dead by now😀
ya, I thought so... rocket man! Keep the nitro's handy!
I did like seeing inside the motor and hearing you talk about it. I don't know much about the inner workings thanks!
Thanks
It’s funny, how motors are different now from years ago. I work electrical maintenance and have for twenty years.

Any ideas as to why VFDs would damage motor bearings?
Near as I can tell its because the wildly different Frequencies that VFD's use to control the speed of the motor, some of the Frequencies make electricity escape the squirrel cage and want to make it to "ground" so they cause micro arcs and Pitting in the bearings, The engineers factored in 60 herts for longevity but when VFD's came about it induced some different parameters than they had considered, look what happens to Slip rings or armatures and they arent even load bearing.

If your a Nerd like me, Id read this stuff any day over watching some silly tv program
www.est-aegis.com/TechPaper.pdf
Might watch Mr Petes Videos First then I would read this LOL
I had a basic idea of how a start switch worked but have never laid eyes on one. Thanks!
Yes
Hi Mr Pete a really edutaining and informative video thanks for posting it.
My dad gave me a Crescent wrench when I started work in 1972 , I am close to retiring and it still works as good as the day he gave it me, my dad passed a good few years ago but each time I use it I say " thanks dad"
Cheers from England
It's great to have tools from your dad. As many tools as my dad had, I only have one or two that were his
You sir, do way more than simply entertain. I take a little of everything you show to work every day. Merci monsieur Pete!
Thank you very much
Nice vid on showing how to tear down the motor a lot of people don't now how to do it and you just showed them how .. Keep it going 👍🏻👍🏻👍🏻👍🏻
Thanks
“What were they thinking?”
Could be a great new series for you, Mr Pete.
That would be a great series. If if I could get enough content
THEY WEREN'T THINKING- THAT'S THE PROBLEM!!!
"Edutainment."
Kind of like "anticipointment."

Yet another GREAT video by
Tubalcain!
steve
I love that word, I hope I can remember it. And use it
Very absorbing Mr. Pete. Thank you for this video. Yes - please do a video on making a belt sander, that would be great. Mike, UK.
Coming soon, and will have eight parts
I enjoyed that. Especially, the part about the bull's hind end. LOL! I've torn a lot of motors apart for the copper in my younger days but, I never realized, how little clearance there is between the stator and rotor.
Nice job Mr. Pete, you are right McDonald coffee is the best, before I retired I stopped ever morning for a cup on the way to work.
Yes
Bean counter's and their ideas for planned obsolescence infuriate and are just wasteful .
I like your idea for position marking during disassembly of the motor, I will be
using that one for sure.
Please keep up the great work and thank you for sharing Sir. You are my favorite shop teacher.
Thanks
Nice tip on the scribe marks around the motor.

Nice Job Mr. Pete as Always ! Next Video , Putting in A Switch Where Needed .Also How About Installing An Air Filter in Those Openings.
Nice easy repair. I’ve rescued a few “junk” motors from the trash by doing the same.
Yes
Great video! Yes, there are lots of us that would like to see a belt sander build. I would like to see you build a carriage lock for a 10" Logan lathe. I can buy one for 75.00, but would love to do another of your projects along with your instructions, (and rants)! I made your toolmaker vise, and your clamps.
I forgot to add my bull reference to your funny remark about blowfly season. I've heard my Granddad describe a sloppy or screwed up job, as looking like "a bull's butt sewed up with a trace chain".
That's a good idea for a project. But I sold one of my Logan machines last week
Mrpete actually sold something! Amazing. The carriage lock is a 1/2" bolt head top right on the carriage next to the tool post. Maybe it's a carriage stop he wants.
I live in the Seattle area... and don't care for the big "S" brand either. Thanks again for all you share with us!
Bitter
Would love to see a belt sander build. Thanks Mr. Pete!
You soon will
Excellent. I like when you go off topic. You are an edutairner
Thank you very much
Thanks for the education Mr. Pete, I didn't know a centrifugal switch was making that noise in the motors with capacitors. You could give a more in depth talk about that type of motor. I would appreciate it. Thanks again.
Yes lol
enjoyed the discussion/cleanup/education.....just so you know I paid attention in class...you put the 4 end bolts in reverse of when you took it apart, nuts were on the cord side...hope I get a passing grade this grading period.....lol
lol
Being one of those "Hammer and Chisel Mechanics" you always talk about, I learned something new watching tonight, I can use a screw driver too. LOL Great Vid as always !
Thanks
Great video, Mr Pete! I enjoyed it very much! As for your talking too much, when a person gets to be our age, who cares! I worked for a while in a electric rewinding shop. Most of the motors we worked on were as big as a mini van. Blower motors from the coal mines in WVA. I also really enjoyed your videos on the Clausing mill. I have a #2 Cincinnati horizontal mill I'm refurbishing. Thanks for all you do. Chuck
Thanks for watching. Your milling machine is a heck of a lot bigger than mine
In my mind, you have earned the right to use any tool, any way you want!!!!!!!!
Thanks lol
100 % Correct, Sir...a TEFC motor should be STANDARD in those abrasive situations. Thank you for your time.
Yes
Yes,then you would only have to clean it every 100 years!
"...tighter than a bull's hind end in blowfly season!" LMAO!! Amazing what a 'reputable' manufacturer will do to save a buck. This is what has happened as the bean counters have been allowed to take over...by management weasels that get paid way too much and can't remember the last time their hands got dirty! Great price (more or less), but a maintenance nightmare. Thanks for another fine video! :-)
Yes thanks
Thank you. Educational and entertaining. Gives me knowledge and confidence to do it myself.
Thanks
Great clean-up! I have seen knifemakers using similar motors to grind steel...certainly a horror story in the making...Thanks, Mr. Pete! :-)
Yes
Hi Mr Pete very informative and interesting your story's are so great . I really enjoyed watching repair of machinery you do it so well . Thanks for sharing best regards Shaun from a cold but sunny morning in South England 😀😀

Good idea, but it does it overheat
No, it doesn't take much air to cool the motor, and I only use the band saw 5 - 10 mins at a time usually. It is barely warm after each use.
High respect and thanks for educating us. I would suggest you vaccuum and wipe the outside with a damp towel. Reduce talking and hepa vac the inside vs talking. Just not healthy and it is extremely important for all of us watching and learning.
see you got to it, thanks. been thinking of using an electrical box and switch on mine but don't like the size
Yes
That video was AMAZING!
Thank you very much
I always learn something from you. So appreciated. Thank you.
Thanks
Please keep on rambling!!! Sometimes the most obvious things you work with every day don't sink in and get thought of until some one points them out.

Yes, that's fine sawdust gets everywhere
Great repair and well done video
Thanks
Good tip on the scribing
Remember crescent wrenches are for metric bolts only and West Virginia fits all AR for SAE bolts I don't think there's a way to use a adjustable wrench wrong keep up the good videos thank you
Thanks
Could be a nice project to build such a machine by yourself. With a new motor, self made wheels and so on. And a switch of course.
Yes
I think a Tubalcain belt grinder build would be a great video
Coming soon
At 9:00 there seems to be wire of some sort hanging close to the axle. It looks like a coated wire of the windings ...
Thanks
Nice job! Would love to see a build vid
You soon will
"Tighter than a ..." Something not many people would know but I can relate to it. 😄 Wonder if the tracking would improve if you moved the motor's pulley in (toward the motor) a bit? Is there a way to add a small shield for the motor's intake?

Nice job and great video - thanks!
Thanks
Mr. Pete, next time please record when you do blow cleaning. We like to see because its satisfying.
lol
I worked in heating and air so I invisioned making a sheet metal box and filter system for this unit lol !
Very interesting! Have you worked on repulsion induction single phase motors like on old Delta.?
Jim
Have not
Hey Mr. Pete! I have a 2x72 belt grinder very similar to yours with a 3/4 hp I have too much side to side (end play? ) How to I go about repairing this?
I saw a guy in high school shop class who was making a chisel put it against the belt (point upwards) of one of those vertical Kalamazoo. It caught on the seam, flipped it around, and drove it into his stomach. He had to have surgery on some internal organ or two.
Wow
I think back to some of the machinery we were using in wood and metal shop (table saws without guards, lathes, torches, etc) with no safety training or even much training at all, and I'm amazed. Also, we were idiots to begin with.
I loved seeing you hammer on a screwdriver to get the end bell off. What did you do to the kids in shop class when they did that?
How would you do it
I would have used a screwdriver as well. I just remember as a kid being told not to hammer on a screwdriver.
A punch would have been the appropriate tool. If you had to use a screwdriver use one that has a shaft that goes completely through the handle.
THANK YOU...for sharing.
Throughout life there are people who made their mark on your life, never to be forgotten, so we can perhaps pass it on to someone else. This is what God intended.
Yes thanks
When I saw you open up the motor, I Mrs. P's toothbrush was going to take a beating!
Your purpose is to "edutain" I have heard that someplace before? Thanks Lyle

It might prolong the working time between cleanings.
Of course you know I live down south and in my time working with guys "born and bred" down south I've heard many a colorful saying used by said men. The funniest one I have ever heard was; " I'm so hungry, I could eat a keg full of wiggling a**holes."
That's quite an expression, never heard of that one. I bet you heard plenty in the Navy. In an upcoming video where I build a belt sander, the very nature of the design provides a shield
Boy, that motor RAN so quiet, but now it's loud as heck assembled? Maybe the top wheel bearings are bad?
Will u be putting a plastic wall between moter and pulley ?
No, a metal one
I understand that Starbuck's coffee is "over roasted." That gives it the flavor and color.
Thanks
COMMUNITY coffee out of Baton Rouge, LA is hard to beat. MaxwellHouse is also good.
I agree that Starbucks coffee sucks and McDonald's coffee is pretty great.
why pay 6 bucks for a starbucks which is too strong, when a mcdonalds senior coffee is less than a dollar and GOOD.
Mr. Pete.
Are you sure it was Oak Leaves that made you so "hyper" the other day ?
I begin to suspect it was Macky Dee's coffee.
There does not appear to be any camber on those wheels.
Correct me if I am wrong please.
lol
You have had it for years and never cleaned it, what were they thinking?
Yes
Mrpete222 A man of few words!
TEFC motors are of course much more expensive because they need to be constructed from materials which will tolerate the excessive heat that results from intentionally failing to properly cool them.
Yes
ok Mr Pete. another great video! what I'm wondering is there an economical way to make an open frame motor essentially a tefc motor?
Probably not
You definitely have different McDonald's in your neck of the woods 'cause our two here have undrinkable coffee. Matter of fact, it's a topic of group conversation quite often. Used to be the best coffee going.
Yes
The safest switch is a foot operated one
I agree that it is a cheap machine but it was made here in America and I wish I could go to my local hardware store and buy one today.
Yes
I think Dayton is actually a W.W. Granger brand. I don't believe you can find them anywhere else
What a mess! Agreed! That's the wrong motor for that application. Any motor on a power tool needs to be a closed design! If the tool is designed to remove material in anyway (Sanders, saws, drills, etc) why in the world would you have a fan sucking in all that debri and blow it into its core? It's designed to last just as long as it's warranty... They don't want it lasting 25 years, they want you to buy a new one every few years.
You are quite right
Great video 👍🏻
Thanks
thank you
Thanks
Are you talking about Charbucks? The only reason that chain survives is because they in the beginning they build near colleges. Millions of students got their first taste of coffee from them and now think coffee is supposed to taste like it was burned and have the taste of cigarette smoke.
Very good name for them
In regards to your using the wife's toothbrush, how do you know she isn't using yours to clean the toilet then replacing it back in the holder? LOL The shims on the shaft are also sometimes used to ensure the rotor is properly positioned to ensure the rotor runs at its magnetic center thus reducing thrust and current draw.
Thanks a lot, now I will have to hide my toothbrush
I thought you would’ve made a dust shield
I'm from Seattle and can't stand that "brand" of coffee either. There are two other coffee companies based there and their product is much better. But I'm with you, the senior discount Mickey D's coffee is a good bargain and tastes pretty good to boot. I have a Dayton bench grinder that is making a racket. It's time to do a bearing job on that machine.
Yes thanks
Thanks for sharing sir..
Thanks
👍Good stuff.
