I use the outer race from a large roller bearing, 8 in od, very accurate and fits the table well, only takes a bit of fiddling to centre it to the spindle
I am a suburban husband/dad. I own a small compressor. You'll be happy to know I drain the tank after every use. I like how it makes an ice stalagmite under the valve. I've shown my kids how compressing air creates heat while decompression is just the opposite. They showed zero interest.
I have an old Campbell Hausfeld 13 gallon compressor that I won't drain any water from the valve. Now I know I will have to poke something up throuth the valve hole. It is probably covered over with rust or dust also.
Me too, even though I dissected several Matchbox & Hotwheels as a child. Hint: If you put them back together after drilling the rivet out and crash them, it's spectacular. Pieces everywhere.
When I have a bad day, I sit down and watch one of your videos... I allow myself to be entertained by your (mostly) subtle Midwest humor and (perhaps unappreciated by some) your considerable intellect... chills me right out... as an aside, I always learn something... lots of bang for the buck... THANKS... P.S. 1 I figured out why you don't have a compressor (which surprises me to no end)... you keep cutting holes in the tanks of the ones you buy! They work much better without holes in the tank... :-) P.S. 2 I ALWAYS replace the thread-type drain cocks on my compressors with a ball-valve type... one throw and PRESTO... it is open... and closes just as easily! P.S. 3 I developed a leak in my smaller (3 HP) compressor... it was a pin-hole... I punched it and put in a heavy self-tapping bolt with a steel and rubber washer... PRESTO- leak sealed and has been running fine for years now!
I bought a couple of those markers a few years ago when you first introduced them as a gift from Bolinger. I too loved them and will continue using them.
This a fun and interesting video. Reminds me I need to drain my compressor today. I enjoy seeing and taking things apart and seeing how things work. Watching you tinker with things and reading comments of persons who know what you are showing us does help. Thanks.
@@M4nusky I hope you depressurized your tank first. I didn't and a slow spiral of mud started oozing them a blowout! My grey beard turned milk chocolate! Now a clean up.
Love seeing the Sucrets tin! (for you youngins, they were cough drops, wrapped in foil...in the rotor tramming, those were the Cherry flavour). Also, I agree that the micrometer is a Montgomery Ward as Moore & Wright had either a text name or oval with M W inside, and would have Manufactured in Sheffield England on the handle. I searched for Montgomery Ward Micrometer and you'll find image of set of 4 items, one looks like yours but in a plastic case and was new for $34.99 back in the day)
Yes, you are correct! I'm familiar with the "Powr-Kraft" line of Montgomery Wards tools, but they also had another line of tools, the "Wards Master Quality" line. A micrometer set is on that famous online auction site right now with the same identical logo.
Great video as always, being from England it was nice to hear you say that Moore and Wright are held in high esteem as the Starrett and Browne and Sharpe measuring instruments, as they were always the tools I used throughout my working life, thanks Mr.Pete
Enjoyed the tank and motor autopsy. I saw a video of a fella with a tank that tore open. Blew out garage windows and the garage door. Split the frame and man-door asunder. Seeing the metal ripped open was impressive. After a tank is over 25 years with fair amount of use on it I think staying away from it is a good idea. Keeping it in a corner or behind some junk. I bet there are tanks that last well over 40 years too.
All the years I have watched your videos I never said thank you I really enjoy your content and the way you deliver your information Thank you very much for all you have contributed over the years
You are probably still right about the switch because the actuator could be stuck and the switch would be in the closed state until you remove the end bell. Thanks Mr Pete.
One of the best decisions I ever made was replacing the 2 hp one phase motor on my Jet lathe with a 3hp three phase. After the starting switch stuck and burned up two capacitors I converted to 220 three phase and a VFD (variable speed drive).
👍Good video. That’s too bad on the Craftsman AIr C. I bought a new 30g Craftsman upright compressor in 04. Very loud but still runs and holds good pressure. Replaced the starter switch years ago. I drain it weekly. Thanks Mr Pete.
The compressor centrifugal switch was probably seized on the motor rotor. Often happens when in a damp environment rust will stop the centrifugal weights from operating
I guess so. I had that happen to me when fine sawdust gummed up the weight mechanism and prevented it from activating the switch. I immediately unplugged it when it happened so the motor was not damaged.
Great video. I have one of those Dellta wood lathes with the legs just as on the catalog. I also have the x-y accessory that you found. But my lathe has a jack shaft for reducing the speed. Great lathe.
Mr Pete - please before chucking the grinder you like, try either replacing the thermal switch or just bypassing it. I think for the work you do it will be fine, if not what have you lost. Good day.
I like that big ol meter... It'd be fun just to wire it series with one of the main sources in the shop and let it dance to the different tools. I always enjoy coming to Mr Pete's class.
So glad you said no to saving it an hoarding it to never be used. It is upsetting to me knowing a bunch of guys will hold onto something in the hopes of getting around to it or "maybe" needing it in the future for no reason, then it ends up rusting away anyway.
Well MR PETE,you Found out Sears secret to their life time warranty.THAT "MUD" was sears cheap stop leak,made out of wood sanding powder oil,flour,and elmer's horse glue.The tanks ,when they rusted out on the bottom were self-sealling.haha I myself have one of those from about 1975 back then they had 2 colors i think a black or silver one and mine which was copper colored which was the "HIGHER QUALITY"one.oh ya i remember now ,it had a asme or certification tag welding to the tank.something like that.great video.
Electronic stores use to sell Weller soldering gun replacement housings because they broke very easy if dropped because they had bakelite housing. One of my Weller soldering guns I bought new in 1976 and is still in it's unopened package. I also have 5 or 6 used ones. Sometime later Weller started making the housings out of plastic.
In shop class many moons ago (a little Choctaw lingo there) we had a bunch of those Weller guns. We made our own soldering tips out of #14 wire rather than the school buying new tips.
All of this was great. I love taking things about, and my shop is proof of it,,,hehe! I get to many projects started, and het back to finishing them up. 👍😜
Mr. Pete I have a set 0-4 of those micrometers in excellent condition. I was told they were Montgomery Wards. The factory case has the MW logo and says "Wards Master Quality" so I do believe they were at least sold by Montgomery Wards. They are vary accurate ( with a Vernier scale) satin finish thimbles and sleeves
The amp meter would be wired to a matching "current transformer" or CT as they are referred to. The CT is like a doughnut which the wire you are sensing current through is run through. Similar as to how your Amprobe works. One thing about a current transformer, if you ever were to disconnect the secondary wires on the CT that goes to the ammeter while there is current flowing through the primary wire the CT will explode
HI MR PETE. as always you are never boring. and always help full. you have a GREAT WAY OF TELLING US THING with out being a dictator. to find such a person. even in this day an age is not easy.. but you have the knack. and we all learn a little something. we must all remember WE CHOSE TO WATCH YOU. or not as the case may be. its all ways good to hear something that we may think..?? but don't do for what ever reason. then hear you say ???? and the PENNY DROPS...??? LOLOL PLEASE KEEP GOING your viewer. Tone from uk.. ENGLAND.. ps. don't change a thing .. it ant broke. so don't fix... ok . Mr Pete
One more use for the brake rotor could be as a flywheel on a larger model steam engine. P.S.: you could also use the ammeter with a shunt (a thick copper plate, that acts as a resistor, google it for more info), you connect it in parallel with the meter and then you can use it at 400A or even more, with suitable shunt. The shunt basically divides the current that passes through the ammeter by a certain factor, like a 100, for example. So, for instance when you have 400 amps flowing through the shunt, you'll have 4 amps on the meter, which will show you 400 on the scale. You can get current transformers and shunt resistors pretty cheaply on ebay.
Some time in the future: Mr Pete its time for you to finally enter the golden gates. Mr Pete it will have to wait I' m scheduled to go to a tool auction and putting finishing touches on a few more vids. Thanks for all the great vids.
Those Weller soldering guns with two levels are on low when the trigger is pulled all the way. For high you have to pull it halfway. (OFF-HIGH-LOW) It is counter intuitive to me.
I once had an el-cheapo compressor that behaved much like that Craftsman. It would start and reach pressure and shut off but, when the pressure dropped and it switched back on, it would just hum until the breaker blew. It turned out that it had a 'start up valve' between the pump and the tank. This valve would 'leak' until the motor got up to speed and line reached some nominal pressure. The motor just couldn't turn over when the tank had more than 20 or 30 psi in it. When the valve got stuck open someone had replaced it with a solid plug so it was closed all the time. Took me forever to figure this out from the manual & parts list, but it was a $5 part and the compressor was serviceable from then on. I wonder if your compressor had a valve like that which someone removed or plugged.
Wow, I can't believe you mentioned Westinghouse and AC without giving Tesla the credit for inventing most of the stuff that makes AC so valuable including the Induction Motor. (no brushes)
I think the Westinghouse meter would need a shunt rather than a transformer. A 100:1 transformer would be good to reduce voltage but not current. You might consider showing a snippet on high current shunts, calibrating one with sand paper or a file must have been fun.
I have actually done the shunt tuning routine. Many years ago on old turboprops and turbojets. DC systems, but the techniques were the same. If the panel meter was replaced, the existing shunt sometimes needed to be adjusted a bit for dead-on readings. Connections cleaned first, then abrasive to make the needle go higher, silver solder applied to the shunt to make the reading lower.
Wow! I was aware of clip-on ammeters but didn't realize they used transformers for current metering applications. That makes more sense now, most of the shunts I have require a delicate parallel meter, somewhere in the order of 25 mA, clearly Lyle's meter doesn't fall into that category. Thanks!
Probably would need a 400 to 5 ratio current transformer. Place that I worked for back in the 1980's used them for large motors. We would have a local meter repair shop relabel 5 amp panel meters to match current transformers. Have a 50 to 5 amp current transformer with matching ampmeter that someday will install on my central air conditioner to measure current flow. Best part of these you only have to put one of the motor wires thru hole or slot in transformer. Dangerous to have a current transformer on a high load with no meter connected ( could get a nice shock). If no meter is connected best pratice is to jumper out 2 studs or wires on current transformer.
I wonder if a person could try spinning the fan by hand to show it the starting coil were the problem. I had a power sander for years that required this (dangerous) expedient. But was it any more dangerous than the way we started .049 and larger model engines? Also, I visited a man recently who had just had one of these compessor tanks, a verticle model, blow up. It had hit the rafters in his garage. It was a bit comforting, actually, to me, because it meant that if mine ever blew it would be going the right direction (because the occidation was on the bottom). Makes me wonder about the horizontal ones though.
i'm very interested in seeing the growler video. i have grampas growler and i would like to see if i can strengthen the magneto magnets on an old dirt bike that has low voltage output since i cant seem to locate a good magneto
I didn't see you manipulating the centrifugal switch or actuator itself. The contacts only. One would look for a missing spring or seized sliding member on the bakelite component. I have that compressor, if you can get some lubricant to that spring loaded portion every few years it helps. They also die because the problematic unloader fails and tries to start the non cap motor under load, which it cannot do. All for the sake of a $4 capacitor.
I know you have seen this but I MUST comment here. A sign in a motor shop said, "All electric motors run on smoke and when you let the smoke out they fail." Sorry, old joke but it seems appropriate. And it is a fitting end for a craftsman compressor, they were a horrible piece of junk made by some company other than Sears. Those third party guys got the job of making them for Sears by being the low bidder! I put Craftsman right down in the same place "Horror Freight" is! Great follow up, I would have paid you $2.00 to see you disembowel that compressor. I cheered as you banged away at it. Just kidding, love your videos...
@Ron Only for the wealthy & in cities. Every neighborhood would need a powerhouse. Edison was trying to be too greedy. Westinghouse was too but saw that he could make a little bit from everyone rather than a lot from a few. He had a better business sense.
@@rustymachineshop9456 Yes and he gave away many patents too. He wasn't in it to get rich. He wanted his work to be for the greater good. He hooked up with Westinghouse for financial backing. Tesla is my hero. Most people nowadays never heard of him even though practically everything electrically powered uses the technology he invented in one (or more) ways. There were others too but Tesla was on a different level. Edison's magic was through persistence and hiring good engineers to work in many directions. He had many inventions but it would be interesting to know his success to failure ratio. Both are very interesting men.
PLEASE, soak rusty micrometer in a rush remover, just leave it soaking for a week. Just to see if it will free up. Watching with interest to see if it will work again.
AC is easily 'transformed' from relatively high voltages/low currents (so less loss to ship through thinner, cheaper - though widely separated cables ), to low voltages/high currents (losses manageable in short multicore cables), and vice versa. Transformers are very much first-principles electric technology known since the 1830s, so Mr W's system won out in the end. I recently read in an engineering journal that more modern semiconductor technology has got the engineers talking about doing HV DC transmission (marked reductions in copper and iron power losses in high-frequency electronic voltage conversion apparently) - so we might see AC vs DC wars again, but I presume nobody will be frying monkeys or elephants this time... Greetings from down under!
Actually you don't have to wait for HVDC. Bonneville Power (BPA) has been operating the Celilo Converter Station since 1970. I discovered it when I was on vacation and drove past it on my way into The Dalles, Oregon. Lots of videos on the construction by BPA. The line runs down into Los Angeles as I remember. The station originally had tubes (mercury arc valves) but now has thyristors.
Mr Pete , do you have any dedicated electrical circuits in your shop/garage? I had to put one in for my HF air compressor. It’s worked fine ever since. It’s been 6-7 years now. Matter of fact, the instructions with mine even said that it may be necessary. While I was at it, I made them 20A.
what a great idea on tramming with the brake rotor
👍
I use the outer race from a large roller bearing, 8 in od, very accurate and fits the table well, only takes a bit of fiddling to centre it to the spindle
Keep keeping on Mr. Pete.
Thanks for bringing back the old Variety Show. Very entertaining.

Pretty sure you will find the dics brakes have some runout built into them. This runout seperates the disc pads after having applied the brakes.
I'm certain the brake lathe manufacturers would disagree.
I like that big ol meter... It'd be fun just to wire it series with one of the main sources in the shop and let it dance to the different tools. I always enjoy coming to Mr Pete's class.
A current transformer is used with this type of meter. For this meter it would be rated 400:5 amps. The secondary is always 5 amps.
Thanks
Loved the Sucrets box full of indicator parts. I remember those from when I would get sick as a kid.

I really like the ammeter ! I think the thing that it needs for it to work for the higher loads is a shunt.

Yes, thank you for explaining that. I have an use that gun in many years
The old metal sucrets box, that's a trip down memory lane, the Altoids box of the 1970s, 😂.
On an amp gauge it's only milliamps that goes through them. Normal its called a shunt that most of the current runs through it in parallel..
When the capacitor is off doesn't start by itself.
I once had an el-cheapo compressor that behaved much like that Craftsman.

The forthcoming production of 'Return of The Growler' best be a good one, if the competition is beer and pork pies!
In Yorkshire, UK a 'Growler' is a most excellent pork pie.
lol
In the US a growler is also a small refillable keg for beer. 32-64 oz. Some areas allow you to fill up your personal growler.
The pica markers are $30 on Ebay in Australia. The Dixon are $30 incl Postage.
Why are you so much, that doesn’t sound right to me
Wow, I can't believe you mentioned Westinghouse and AC without giving Tesla the credit for inventing most of the stuff that makes AC so valuable including the Induction Motor. (no brushes)

Did anybody realize Mr Pete was using Craftsman tools to take apart the air compressor ?
At least all the tools to me looked like it.
Not the "Horror Freight" cut off tool. I love it when he makes fun of tools when he was the one that bought them. I probably do the same thing.
Great episode Mr.Pete! I thought it a bit funny when you said you did not really have an air compressor (as you were dissecting one)!
Not sure about that Moore & Wright logo. Could be a copy.
A video about cleaning, fixing and calibrating the calipers would be much appreciated.
Wow never seen a wood lathe with a compound slide hmm. Never either thought of tramming out the mill with a rotor and I have rotors by the dozen
The phenomena that causes the current meter to spike and then settle down is called hysteresis surge current.
My Moore and Wright from the 70s does not have MW on it. Maybe US exports did.
You are great. Don't change a thing. As a new subscriber, I only got you in my feed last week??? Covib made many new utube viewers.

Lets face it we are auction addicts and it probably cannot be cured. Thanks for an interesting video. Keep on keeping on.
I went to another one today. And I am going to yet another one tomorrow
Probably would need a 400 to 5 ratio current transformer. Place that I worked for back in the 1980's used them for large motors. We would have a local meter repair shop relabel 5 amp panel meters to match current transformers. Have a 50 to 5 amp current transformer with matching ampmeter that someday will install on my central air conditioner to measure current flow. Best part of these you only have to put one of the motor wires thru hole or slot in transformer. Dangerous to have a current transformer on a high load with no meter connected ( could get a nice shock). If no meter is connected best pratice is to jumper out 2 studs or wires on current transformer.
Thanks

I’m working for Uncle Sam have to watch later
I wonder if a person could try spinning the fan by hand to show it the starting coil were the problem. I had a power sander for years that required this (dangerous) expedient. But was it any more dangerous than the way we started .049 and larger model engines? Also, I visited a man recently who had just had one of these compessor tanks, a verticle model, blow up. It had hit the rafters in his garage. It was a bit comforting, actually, to me, because it meant that if mine ever blew it would be going the right direction (because the occidation was on the bottom). Makes me wonder about the horizontal ones though.
Good stuff!!!
👍
i'm very interested in seeing the growler video. i have grampas growler and i would like to see if i can strengthen the magneto magnets on an old dirt bike that has low voltage output since i cant seem to locate a good magneto
The centrifugal switch may have come free when you hit the endbell of the motor. Just a thought but you may have been right on the money
Never thought of that, I might have broken it loose
I didn't see you manipulating the centrifugal switch or actuator itself. The contacts only. One would look for a missing spring or seized sliding member on the bakelite component. I have that compressor, if you can get some lubricant to that spring loaded portion every few years it helps. They also die because the problematic unloader fails and tries to start the non cap motor under load, which it cannot do. All for the sake of a $4 capacitor.
Flywheel might be source of iron or steel.
Love it - thanks.
I know you have seen this but I MUST comment here. A sign in a motor shop said, "All electric motors run on smoke and when you let the smoke out they fail." Sorry, old joke but it seems appropriate. And it is a fitting end for a craftsman compressor, they were a horrible piece of junk made by some company other than Sears. Those third party guys got the job of making them for Sears by being the low bidder! I put Craftsman right down in the same place "Horror Freight" is! Great follow up, I would have paid you $2.00 to see you disembowel that compressor. I cheered as you banged away at it. Just kidding, love your videos...
Westinghouse air brakes
Love your work
It was Tesla who opened Westinghouse eyes to AC power! He is the real inventor of AC use! Westinghouse was the money!
I was going to reply something very similar to your comments, but you said it much better.. Tesla was a brilliant man..
Did DC even have a chance considering how much electricity we use today?
@Ron Only for the wealthy & in cities. Every neighborhood would need a powerhouse. Edison was trying to be too greedy. Westinghouse was too but saw that he could make a little bit from everyone rather than a lot from a few. He had a better business sense.
Tesla could have the richest man in the world 🌎 but he sold all of his patients that were valuable and died flat broke
@@rustymachineshop9456 Yes and he gave away many patents too. He wasn't in it to get rich. He wanted his work to be for the greater good. He hooked up with Westinghouse for financial backing. Tesla is my hero. Most people nowadays never heard of him even though practically everything electrically powered uses the technology he invented in one (or more) ways. There were others too but Tesla was on a different level. Edison's magic was through persistence and hiring good engineers to work in many directions. He had many inventions but it would be interesting to know his success to failure ratio. Both are very interesting men.
With the air filter being off, the piston seal was probably shot. That is a lot of dirt intrusion in that tank..
Agreed
PLEASE, soak rusty micrometer in a rush remover, just leave it soaking for a week. Just to see if it will free up. Watching with interest to see if it will work again.
Maybe I will
AC is easily 'transformed' from relatively high voltages/low currents (so less loss to ship through thinner, cheaper - though widely separated cables ), to low voltages/high currents (losses manageable in short multicore cables), and vice versa. Transformers are very much first-principles electric technology known since the 1830s, so Mr W's system won out in the end. I recently read in an engineering journal that more modern semiconductor technology has got the engineers talking about doing HV DC transmission (marked reductions in copper and iron power losses in high-frequency electronic voltage conversion apparently) - so we might see AC vs DC wars again, but I presume nobody will be frying monkeys or elephants this time... Greetings from down under!
We've been using HVDC transmission for some time in the US.
Actually you don't have to wait for HVDC. Bonneville Power (BPA) has been operating the Celilo Converter Station since 1970. I discovered it when I was on vacation and drove past it on my way into The Dalles, Oregon. Lots of videos on the construction by BPA. The line runs down into Los Angeles as I remember. The station originally had tubes (mercury arc valves) but now has thyristors.
"its a one way trip" ... Ha .. Sounds like most of the junk at my shop!!!..
Hi Mr Pete, I interested in the delta lathe compound you got at auction? Are you thinking of selling it. Neil M.
Air brakes on trains?
Mr Pete , do you have any dedicated electrical circuits in your shop/garage? I had to put one in for my HF air compressor. It’s worked fine ever since. It’s been 6-7 years now. Matter of fact, the instructions with mine even said that it may be necessary. While I was at it, I made them 20A.
Mr Pete you let the magic smoke out. LOL just kidding, that's what we call it in the electronic world.
Soldering iron looks just like mine, crack and all
lol
We have the reach here on base
