- Motor and Drum Switch wiring starts 12:33
The Myford saga continues. We swap out a crappy old single phase motor for new smooth single phase electric motor. Including turning a new bushing and machining keyways on the Myford's milling attachment. Then wiring in a drum switch for the electric motor, featuring both forwards and reverse, with wiring diagrams.
0:00 Machining and adapter bushing.
12:33 Drum switch wiring.
21:26 Test cuts!

Would you recommend buying a Myford ML7? Looking at buying my first lathe and I'm used to working on a Emco Maximat 11 and a Swedish version of the South Bend named Blomqvist BSN600. But there are currently a few Myfords for sale in my area that have peaked my interest.
No. Not if you want something that works like an Emco 11. Myfords are great if you want a little lathe to play with - lots of accessories - and much better than a cheap new mini lathe. But If you have space, for the same money, you can get a larger boxford or emco, which are both really common and easy to get parts for etc. The extra size is going to make them way more rigid.
If you do want a myford, try and get a Super 7 with a gearbox. The Super 7s have 'modern' headstock bearings instead of old solid white metal bearings like the ML7 which drip oil everywhere - and a gearbox is so much better than change gears. I'm not saying I'm an expert or that there's anything wrong with a Myford ML7 - but that's my shopping advice.
@@GeoffreyCroker Myford 7s are also ridiculously expensive compared to less "pretty" lathes like Boxfords and so-on.
“Piqued” rather than “peaked”
Boxford are clones of the south bend 9 too, much heavier built and precision taper roller bearings on the spindle, loads of interchangeable parts between all of the clones except the smart and brown sabel which has a different bed profile
Everything the venerable Mr Croker said; if I were doing it again I'd at least wait for a Super to come up, but I should have gone for a Boxford, or even a mid-sized Colchester. Instead I've got two Myfords. It's a sickness. There is no cure. Don't fall into the trap...
Yes! Do a Part 12 where you just add small rubber pads to the bottom of that housing.
I think I will turn that into a 100 part instagram story 😁
@@GeoffreyCroker It's the only way...
Great stuff! Thanks
Not gonna lie. This was the first lathe restoration series on YT that influenced me to buy my first lathe. Still enjoy the saga ;)
Thank you Ca Lem 👍👍
Me too, this series inspired me to made my homemade lathe following the myford project cz this video is fully detailed
Just this morning I was thinking, "Mr. Croker hasn't posted in a while. I miss the Rover project."...and this is what I got. yay. glad you are well sir.
@Geoffrey Croker … I found this extremely helpful as last week my motor shorted out scaring the 💩💩 out of me.
So I have had to start stripping it down to get rid of the original rubber coated cable, to replace it with better quality.
I took photos of the switch to help me with the rewire, but now I can do screen shots and print them, many thanks 🙏
Animations and sounds effects - pure dead brilliant! And that depth of cut.....
Always a relief when the smoke stays inside the wires likes it's supposed to 👍
I paused the video to write this comment. I experienced great pleasure watching watching you put the bushing over the shaft and then the pulley... Not creepy... It was just so satisfying.
I've been driving that behavior out of my nephews. Oh that's so satisfying....
It took seeing how you did this for the reversing rum switch to make sense! Thank you. And also others safety warnings. On the wiring and these drum switches. Best to install a double pole double throw to the motor. Meaning when the switch is "off" no circuit at all goes to the motor. Then use only the top 4 connections for motor reversing. Otherwise one leg to the motor, the jumper connection 4 & 6 to the motor is always "hot" even when the reversing drum switch is in the off position. Most big button on/off switches are DPDT and you can get DPDT that are like wall switches that here in the States will fit in what we call a surface mount box or old work box. Thanks again for your explanation!

Great graphic to explain the wiring as you performed it! I just wish I could follow it! Great work.
Thanks for giving me another way to procrastinate on my Spanish homework lol. I just got around to actually making the motor on my lathe run, now I just need to wire it, and watching your videos has been pretty motivating, so thanks mate!
i have 4 hour test tomorrow morning and i should learn, but this indeed doesn't help! and fun fact, today i took apart my lathe motor because it has bad bearings... must be a coincidence ;)
De nada
lights action camera sound filmography timing editing incredible.
Clever idea with the pulley key(s) well done
I jumped at the 80thou depth of cut explosion!
Outstanding!!! Framing, lighting and focus are out of this world. Top Drawer! As usual dialogue complete with puns, accent, sarcasm and humour are sweet. Thanks for sharing.
Maybe the most underrated content on TH-cam. I so appreciate you not holding your camera arms length away for 1/2 the video. I for one like the POV of work with your voice over explaining your tactics.
Bravo Sir from Fort Worth Texas.
Post more!!
This is actually the video I needed with the humor, voice, work. This helped.
Best edited, composed videos on TH-cam. The animations showed the different methods of attaching the wires. Great detail!!
Your videos are such a treat!! Thank you for all your hard work in putting them together for us.
Thank you 👍
I'm glad it's not just my belt guard that rattles .. parting off makes it jump around like a mad thing; makes quite the racket when it starts catching the back gear! I mean, not that I'd ever forget and let it do that, you understand.
Seeing as I bought a Myford ML7 purely so I could rebuild it using your series as a guide, this update really, really thrilled me.
This was fun. Thank you, Geoffrey.
Glad you enjoyed it 👍
The quality of your videos is outstanding, i hope you never run out of projects and inspiration to upload more of them!
Fantastic video. Nothing better than having a spare hole ! 5:19
This is an absolutely awesome series. I just picked up one of these lathe over the weekend. This video series has been very useful to get the old girl working.
Fuck I miss New Zealand! Helps to hear your voice though. Glad you’re doing ok!
Just makes your day when a Geoffrey video comes up great! Stay safe down there in New Zealand cheers from the UK
Honestly Geoff, your videos are top notch. Great work
Geoffrey! Glad to see a new posted video, the opening was hilarious and well done. The trick with the bushing and key ways was bloody brilliant! Nice to see your still "with us" and have not succumbed to the "sickness". Stay Safe Thanks for the share!
Such a pleasure to watch!
Thank you for taking the time to present your excellent work!
Lovely job on the visuals in this episode!
Your video editing skills are just as amazing as your explanation of wiring switches. Restrictions in Australia are easing and I've heard it's the same for you guys across the ditch. Cant wait for the next one!
Awesome story telling. Up there with this old tony.
Love it
Already the best part of my weekend. Thanks Geoffrey!
Thanks Adriaan 👍
日本人です。毎回の動画、楽しみにしてます。あまり英語は得意ではありませんが、次回の動画も楽しみに待ってます。ディフェンダーの動画、心待ちにしてますね～。
Production values thru the roof! Great stuff.
Oh man, worth being in lockdown to have this stellar content! Thank you!
At this point im wanting to send a search party in for him. Missing the uploads. Said it before but it's still the one channel I will actively check for uploads.
What we All have been waiting for, Test run...! Yeah Great job 😁
a well edited video on TH-cam, so rare
Great video Geoff, the work on those bushings was tops.
Cheers
Mark
Love your videos. It's a real treat when they come up.
Hope you and those you love are well!
Great video - perfect amount of cowbell!
As a mechanical engineer, that was the best eletrical drawing I have ever seen! It cured my electrophobia a little
I enjoy your sense of humour and have always enjoyed your videos. Thanks
So glad you decided to upload after a long wait.
Clicked faster than the springboks making bad decisions on the pitch.
Ninja edit: You used the old motor to make a bush for the new motor. You truly are heartless. Spare holes are always nice. I keep a few myself.
Really like hiw you handled the keys on the bushing. Great idea
Geoffrey, ditch the top slide and make yourself a solid tool post mount that bolts directly to the cross slide. You’ll notice a huge improvement in rigidity.
You can save the top slide just for turning tapers and the like.
Darren
Brilliant series Geoffrey I’m looking to buy Myford ML7/Super 7 in UK this has been very helpful and informative
Good to see you back in business again, mate!
Clearly one of the best TH-cam channels on..., well TH-cam.
Been bong watching and it is a blast.
Wow that was brilliant. I just wish I could understood it all :) An 80 thou cut would take out the grid of my entire neighbourhood !
Glad to have you all back , excellent as always ....
Regards

Thanks Robert 👍
Another awesome video, we need more vids, they are super informative, good job!!
Great to see another video from you again. Cheers
Thanks Geoffrey, that is very helpful. I will have to rewatch a couple of times to work it all out, but the graphics are excellent. As always your videos are very well made, informative and entertaining. All the best, Mart in England.
TWAT !! made me jump with that fire ball at 80 thou lol, thanks for your upload.
awesome drum switch explanation thanks for the videos
That thing is quiet compared to the Atlas/Craftsman. Looks really beautiful. You did a great job restoring it.
Long time no seen. Nice to have you back. Thought never see you again.
My bloke is back, hell yes!
Today I leaned that I am not going to be an electrician when I’m older, that wire diagram made no sense to me😂
Electric motors are black magic. I'm an electrical engineer. (well, specializing in I&C). Electric Machines was not my favourite course!
Its easy if you master the principals of electric motors.
@@MichaelSteeves Wow, I'm a retired plumber and HVAC tech- I can't engineer the things, but I know how to work with them and workan applications chart and I do understand the magnetic theory- it seems so simple after the "right" explanation, which began with Ohm's Law, how that is the same as the Pressure/flow of water in a pipe, and finishes with the sympathetic acceleration of neutrons through exposure to a moving magnetic source. It's fairly basic science today, Tesla figured it out and everybody has been riding that coat tail since 1890. Machines and gears and clocks and such were my favorite toys as a child, so ratios and such are second nature to me- sorry it was a reach for anyone, because it shouldn't be, as the forces have been with us forever, maybe even the Egyptians were working it!
I'm older, not an electrician, and it made no sense to me, either.
@@MarkH10 Yep, I got nothin. But it's always good to watch Geoff even if you don't understand what he just did.
Heroic work from the little lathe!
I reckon 😁
the animations are top notch!
Great video, always a treat to watch you content. Part 12...painting the new motor to match the lathe and making a custom rubber silencer?
Not sure why, but I imagined this lathe was much bigger when you restored it.
Great videos Geoff, Thanks mate.
Loving the diagrams and explanations, even though they meant absolutely nothing to me... not being electrically minded you see. Nice to see you're OK and still posting. Now you have a challenge, since this video has raised the bar so much with the sound effects and artwork, people wil be expecting it on the Landie project too!
My Pommy mate in Australia, with life-long experience of lathes and similar machinery, considered the best use for a Myford was as anchor for mooring a boat.
Step key and slotted bush would work.
Maybe as you did but with the keys at 90 degrees not 180.
Both with clamp screws, better holding and alignment.
Recommended for slide fit pulleys.
Mr. Croker, your filming, editing, and narration are best in class. Your channel is critically underappreciated. I do my best to pimp it out to interested audiences and I'm always proud to be a patron.
Any tips for those wishing to start making videos? It seems like when you started you were birthed fully formed from the head of Zeus with the appropriate skills. Even your oldest videos have an extremely high standard of quality. ATB from America.
Great video Geoffrey. Liking the animations, helps to explain things much better. But next time you need to get yourself one of the Newton Tesla units!
Im from New Zealand and also have recently bought an ML7, I saw your idea for machining new leadscrew nuts and am in the process of finishing them off, ive also decided to convert to metric at the same time and make new dials for it. I got some new feedscrew and will machine it to take the handles.
Would love to have a chat about a few things if thats possible :) Thanks for the vids, keep it up!
Thank god hes back! Love your videos!
aww. My ML7 has that same rattle in the belt cover. it's one of their little quirks :) Cheers from over the ditch!
Fond memories of doing restoration work on a 60's Schaublin 135 lathe during my internship... Busted knuckles, oil drenched overalls and swear words included. Hope to get my own one day!
Great video!! take care and see you next time!!
Nice to see you back :)
Amazing job dude. Keep doing!
Thank you 👍
JEEZUS FREEKIN CRISTOS!!I've never yelled at my television this much,...ever.!??...!!
Ayeh, ayeh! AvE-reference appreciated
Very much enjoy your videos - just catching up on your back catalog (hence why 6 months behind everyone else!) Very clear, well edited and I enjoy that quirky antipodean humour... Now gotta wait for the next Landy episode.
I use treadmill motors on my lathes,,,can't beat them,, do quiet and smooth and the soft start is so much easier on the lathe and I love the speed control, no more pulley changes
Awesome vid. MORE!!!
Personally I probably would have gone with the single T-profile key. At the time you were considering the options, my reasoning was that this way the power is transmitted from the motor to the pulley via the key . With the 2-key solution, the motor power is transmitted via the motor key, the adapter bushing (which has very little cross-section by the longer key), and then the second key.
Then as the video progressed, it became apparent that the extra machining for the one-piece key would have been made up for by the modifications to the other keys, welding, etc.
Great outcome either way. I hope that broken motor went into the stash or to someone that fixes it -- it's probably something simple and/or educational to fix
Thanks for sharing!
Everyone's a David Bailey until it comes to TradeMe photos :) You need to make sure you take the photo by candle light, preferably during an earthquake balancing on one foot :p
Dude... it fills me with rage. Every cell phone is capable of taking better photos than what a lot of the big second hand sellers use. Don't tell me they're taking photos through a potato by accident.
Just for the cover that still rattles Geoffrey, could you just grab some of those little sticky rubber dots once you're allowed at the hardware store again? The kind that you stick under furniture legs etc? Great video as always, she sounds sweet! And I'm keen to see what you do with that pantograph too!
Great video 👍
I was listinin to a Kiwi on a podcast earlier today and I was wondering what you were up to and if you were out playing on your big deck, behind the house, but I was wrong, you’d been busy with this there vijeo. Much appreciated. Superb stuff, and glad you kept the angry pixies inside the electrickeryspaghetti. Well done!
Thanks Jocke 👍
This is a great video! *Chef's kiss*
I would have been interested in knowing the pulley run-out after the bushing was installed.
I would have considered just manufacturing a replacement pulley for scratch.
Fun video and nicely edited.
Good to see you back. You are the Yin to Maximus Ironthumper Yang.
I love Maximus ironthumper
Bro.. We need land rover videos!
I love these videos!
Love these videos
Just incredible
Always quality mate
Great video, thanks.
