I miss "The birds Fly South" in the end of the videos! Bring it back dude!
One thing you can do, if parts are unavailable (start switch) is to use a potential relay. They are used on HVAC units (like your refrigerator). They are mounted externally (usually) and are easy to install, they come complete with instruction sheets for capacitor run or start and run capacitor type single phase motors. Its not a problem if the motor is reversable or not by external control (like a lathe is).
I was taught something by and old fella that used to rebuild the motors we took out of every machine tool that came into our shop for rebuild. You could hardly recognize them when they came back, he cleaned, polished painted, replaced. Abused fasteners and every darn slotted screw he found. I went to pick one up one day and commented on his work. He said “young man I take pride in what i do and I know the motors we rebuild will outlast the original. Now you take that back and don’t just throw it into the filthy, rusty hole it come out of. Clean it paint it, replace the bolts, washers belts and the paint splattered wiring and give it nice place to live.”
Might have been a good idea to replace the start capacitor too, while you were at it. And maybe the hot sauce would have freed up the woodruff key even better than Kroil.
If the run capacitor is fine and working it should be left alone. Newer capacitors have a higher failure rate, ever have a run capacitor or start capacitor blow up on you when using it? I have and the capacitor was not that old, and maybe had 100 hours on it. Note: the vent didn't blow open, but the whole bottom of the capacitor blew off!
Nice. I was gonna say a couple drops of that sauce might loosen that mug right up!
Steve, your advice violates the unwritten American motto: Too much is almost enough!😗
I was surprised that you didn't pop the cover and check capacitor connections.
A weak start capacitor will cause higher starting current and more stress on the starting switch contacts. Replacing the caps while you have it out is good insurance if they are more than a few years old. Also you mentioned that your lathe does not have reverse. Unless the start winding is hard wired to the run winding you can reverse it by swapping the start winding connect to the run winding.. Adding a reversing switch may be fairly easy for you to do. A single phase motor can start in either direction but you can not switch directions on it while it is running like you can a 3 phase motor.
Morning y’all! My Colchester Student lathe is still going strong after 45 years. So is my Bridgeport milling machine. Two essential tools. 😊
I have a Colchester lathe and an unnamed mill both older than i am. both cause less trouble than my new import lathe
I’ve heard that there are people who live without a lathe. It takes all kinds I guess. Yours is a beast!
Looking forward to seeing the three of you on Sunday. Stay safe and keep the videos coming
Good luck to your friend. Thanks for sharing the lathe repair.
Thanks a lot for quality content Steve. You and Kurt at Cutting Edge Engineering are my absolute favorite channels.
Thanks Steve. This is one of my favorite channels now. That is a great repair on that switch. Your lathe is a beast. I have 2 smaller ones and a mill and I enjoy your take on all your projects so much!. I first went to Kentucky about 9 months ago due to work. Now I go every 3 months and I absolutely love Kentucky and the people there. Being from the south it feels like home.
Nice job Steve.
Thanks for sharing. 👍
The old repair was one of the first videos I watched when I found your channel. You really helped me on my journey since then
great video,thank you Steve for sharing .
Awesome as Always... Great Content.
Your lathe became a diva!! .... "I refuse to perform unless the cameras are rolling!!!" ... 🤣😂
Thanks for sharing. As someone for Louisiana and heat is good as long as it tastes great. I’ll give it a shot and if it too hot for me I know lots of people that love hot lava. Thanks for the info.
Been there done that, no t shirt tho. I ended up with a 12 X 30 Hendey from one of the shops that I bought back in the day. It had a taper attachment and a 3 hp motor with a bad switch.
I still regret selling it but I also had 3 other lathes including a 13 X 42 DSG and I needed the room. I loved the unique method that was used for threading that made it so much easier.
You had the lever on the cross slide to move it back and forth and the no watching the dial when engaging the feed. A truly unique setup
Steve, I totally agree with you about greasing bearings. I'm retired now, but during my working days I've been in ventilation and I've seen more bearings going broke by too much graese then by too little grease. If you've ever had the possibility to look inside a totally closed bearing (think of a 2RSI type) than you will see how little grase inside these bearings is. And those bearings have to deal with that all their rolling life.
Love watching your videos. you have an amazing set of talents. rebuilding that starter switch was amazing. it looked factory!
You're a UA-cam natural Steve, you seem so relaxed and sincere in front of the camera. I just discovered you channel and have been binging, and just happen to watch the video of the first repair a couple days ago. Keep up the great work.
Thanks for watching
Cora thinking, If he's just waving that hand around, he might as well be petting me.
Spent a full day getting a key way out of a compressor shaft. As always enjoy your videos.🇺🇸🇨🇦🇺🇸
I don't have a metal lathe yet but if my Powermatic 66 tablesaw don't work I gotta fix it ASAP just like you and your lathe.
My monarch has a 7 1/2 hp, 3 phase motor. Great machine. My Cincinnati hydroshift is my go-to lathe.
Doc T here: don't put your back out! Use that fancy electric fork lifter!
The lathe is definitely my favorite piece of equipment. Also an engine hoist is a godsend in the shop.
I think I heard my mom say "“Lift with your legs, not your back!!!" while watching you lifting that motor 🤣
I think I watched you make that repair, VERY GOOD👍
Good Saturday Mornin, Steve, Elizabeth, Cora and Grits! Good instructive video. Save your back, use fork lift. Machines do the work, man thinks. Always a pleasure to have Steve in my shop on Saturday mornings. I did buy a bottle of Brad's Hot Sauce. I too, am a fan of hot sauce, flavor, not heat. Thanks and God Bless.
Hey Steve, glad you got it working. That motion you dislike in a spad connector is actually a good thing, the solder connection is actually a weak point, where thr solder ends is where the wires will break. Workharding is real, a lesson learned the hard way by and learned from the us navy. On the bright side you probly will not see that failure during the 100 or so more years you will be using your lathe. Howdy to the family.
Thank you for sharing. 👍👀
Great job 👍!
Thanks Steve
Good video Steve wish you all the best from fletch from the UK
Cora is loving dog, its always fun to see her......
Another good job 👏
A single phase motor has "start components", being a Start Switch, Start Capacitor (and Run Capacitor if so equipped). Why you didn't check the capacitor(s) is beyond me. A weak or bad start capacitor can and does put excessive amperage on the Start Switch contacts. This problem most likely will re-occur.
Great Video Steve.
Going to try that Hot Sauce..
Got to love a Hendey Lathe!
It must be the time of year Steve, my 50 year old Maximat lathe just had a gearbox rebuild and will be getting new start/run capacitors. Made in Austria, it is a high quality machine with plenty of years left in it.
Great video, thanks.
Best wishes, Dean.
I run a Maximat super 11 at work. They are a sweet machine
@@SteveSummers they certainly are.
Where the heck did my rag go, oh, there it is, right in front of me. I must’ve laughed for a full minute.
Stay safe and we'll see you next week.
Steve, we ordered the hot sauce off amazon before you had finished the video and got it 2 days later. We like it. We don't like spicy things, but adding it to home made chicken soup really brought the flavor thru with just a touch of heat. Good product we are ordering more. Thanks,
I love hearing that😁. I'm not a big hot sauce guy either but it adds great flavor and some kick . Thanks for getting back with me . I appreciate you taking a chance on the sauce.
You had two good helps on this one, Corra is in high cotton with the new vest! Great to see you and Elisibeth back in the shop and smiling again. Out your shop window, sure looked cold,,,burrrrr! Se you Sunday, will maybe Monday, Stan and Phill are gona try try to pop in on their way back home. I just moved the 2024 Fly Wheeles event to the top of my bucket list! Hope the old bucket last another years (@@)! Bear.
Steve - I've commented before, but I have to say it again. Your channel is my favorite, not just because of the cool stuff you share, but because you allow us to see what you and your life are about. You and your family make me feel good about the world. Thanks, brother!
Steve; I'm from Caldwell County in KY. What Country are you in?😅
Sorry to hear about your lathe. I hope you get the lathe back up running again quickly. Regards, Aaron.
Good feelings are priceless
Seems like Brad could be grabbing the other end of that motor! 😆
Love the smell of Kroll oil. It’s a better “wake-me-up” than coffee!😅🤣😂
My lathe is down too. Motor cutting out. Shop said the motor was fine but I found some crispies in the control panel. Gonna rewire the whole thing.
Que the soldered vs crimped spade connector comments here............... that fancy new truck sure takes up a lot of space in your shop.
This would have been a great time to rewire that motor for reverse operation.
Great content
Cora simply will not stop being grateful.
Any time I can get extra content from your shop, Steve, Im happy. Too bad you cant film more at work, seems like you've got a really interesting job. Have you ever explained how you landed there in a video?
For reference my Goodway (Taiwan) 14 x 40 Lathe came with a 5 horsepower 3 phase motor. Maybe you should have used the shop forklift or the cherry picker to lift that to the bench and back down. The extra minute or two will be worth it in the long run. Back problem are no joke. Be Safe like Cora the safety dog.
A new subscriber here Steve. I am a chemical engineer but I really have become disillusioned with big Pharma.. I decided that while I am searching for a position I love that I will start a mobile welding and fabrication business which includes a steam powered machine shop
Heat the wire, not the solder, will flow in better.
Where the heat goes the solder flows.
@@dannyl2598 remember seeing a guy try and solder with the a torch, just blowing the solder away and wondering why it kept dribbling on the floor
Great video as always buddy! You know what they say,"lift with your back, not with your legs!"
That is what I was always told🤪
Hi Steve sorry to hear about your lathe. It always sucks when equipment goes down.
Sauce ordered👍🏻
My father's words of genius long ago, and cause to ponder, "If it ain't broke, don't fix it." Good advice that we need to heed.
I just ordered a bottle of Full Tang Hot Sauce ! ! !
I watched both of your videos and very impressed. You did a great job. You are man of all types of trades, n not afraid to get into something you never have done before. You are irreplaceable. Men like you are far n few to find. Thanks for everything you do.
LoL, 😊. I've never been afraid to break something that is already broke. Ya learn quite a bit trying.
@@SteveSummers YES you do. You learn alot, and like you say if it's already broke you will see what caused it and try your best to fix that also. If something goes bad at home, I need to see what n why it failed, repair it to best I can do, and if not, then get what I need. We are both wired the same in most cases. I am no machinist, just a retired residential electrician, but I just need to see what went wrong. Thanks for your comment. It really means a lot.
@@mdvener Thanks for always watching the videos Marty. I appreciate it very much.
@@SteveSummers I look forward to them every Saturday.
good job Steve and just to let you know ....your my saturday morning cartoons now days ......umm i ment that in a good way : )
2 visits today. Thanks eh. Any time we have to deal with these motors they are generally a pain in the toosh. They are generally heavy with a hard to handle shape stuffed in, under or behind something. If this motor fails changing it back to 3 phase is sure the way to go. Big single phase motors like this one are horrendously expensive. Well fella you have your baby back on line. Feels good eh, LOL.
Your collection of different hammers reminds me of mine and my wife wondering why I need different ones - "Isn't a hammer just for banging things?" Well not exactly, I reply!
It's funny that only the other day I was re-watching your switch repair video and wondered if you ever replaced the switch with a new one. Question answered I guess.
There's nothing as permanent as a temporary fix. At least until it fails again. I will be giving that hot sauce a try. I like hot sauce but not when it melts your face! Thanks for the video!
Excited to try out this sauce!
I agree with others. A little back story on the development of the sauce would be cool. If he’s compfortable doing such. Tangentle for sure. However 1.5 years ago I followed you completing a shop foundation and raising a roof. So I’m convinced this channel can kinda go anywhere. Love it! Cora’s becoming my favorite personality tho. Sorry Steve!
My shop dog likes to micromanage when I’m working close to the floor as well
Thanks for another good video. Too bad you don't have something to lift that motor (bridge crane, electric pallet jack, engine hoist or something) 😉. It's always good to get the lathe back into service.
There is an electronic replacement for that start switch to use on single phase motors that are started often.
Careful there, Steve…you only have one back… I remember the video when you rebuild the switch. I was impressed when you made the copper rivets…
good video steve
I think I popped my back out at least twice while watching this video, split my spleen as well. As always great content, that’s a dandy of a motor!
Time to bring in a new piece of machinery to restore & to further the capability of your shop.
Cora and homie the safety officer couple of UA-cam!
Nice vid Steve.
I hope that has the problem fixed, Steve. Intermittent electrical problems are just the worst. Also, bought a bottle of Brad's hot sauce, we'll see how it is!
Morning Steve and Kora.
I wait for your videos every week and they're very informative, but I have to say since Cora came to the videos I've fallen in love with her, we have a Beagle her name is Fannie-may and I know Fannie and Cora would have a ball together. God bless!
Cora is full of energy and requires a lot of attention. I'm glad she showed up
@@SteveSummers Same thing with Fanniemay but returns with a lot of LOVE!
Cora is soo much help : - )
Morning all!
Morning
I need one of those vests for my dog
I would love to try Brad's sauce but Amazon won't ship to the UK 😒, please let Bard know if he ever is able to ship internationally he has a customer waiting for him here in Dorset, England
Steve, how many amps does the motor pull.?? Being single phase and 5 HP
I had good luck pulling keys with a small drill press vise. You clamp the key in the vise it does not slip as easy.
Looking at the comments I see someone says you should replace the start capacitors. He is correct. These are rolls of paper with foil between. Due to age and products within the paper it becomes acidic and the capacitor starts to fail in multiple ways. With your start capacitor this is liable to create higher pulse voltages across the contacts of these switches. You may believe you have fixed your issues, that though may be a temporary fix.
You could have saved yourself a lot of work Steve, just keep a camera aimed at the lathe😂. When my lathe motor stopped it literally let the smoke out so that was a whole new motor but my compressor has points that get carbonised so every 5 years or so they need a light file and it’s back in business. It’s a bit like a tune up really. Love the channel and the content. Cheers Stuart 🇦🇺
@5:11 .. Hello hernia my old friend! :)
When will You give Elisabeth a good hug for participating? Joking!
I heard you say your in Kentucky. What part are you located in ? I'm from Kentucky also (extreme western KY). I have watched some of your videos and I like what and how you do stuff. Keep making the good videos.
I think you need one more lathe. 😁😁
I ordered a bottle of the hot sauce. Will let you know how i like it.
Quite bold of you to say it was easy before reassembling and testing 😂.
Nothing wrong with the plastic switch.Unlike the Bakelite switch. I never had a problem with them. I would check the starting and running capacitors.Don’t forget to put the insulator in the cast aluminum cover,on the contact side of the capacitors. I had one of those in a 5hp.that I bought from a guy who was retiring.Someone came in and needed a 5hp. 4 pole for a air compressor. I hooked it up to test it,since I didn’t rewind it myself. I put my hand on top of it so,it wouldn’t jump. The capacitors had moved and,were contacting the box.It literally knocked me on my ass.😂😂😂
Looks like the original was phenolic not bakelite.
