No really... this changed everything. All my tooling to this date has missed one thing. Hardening. Hardening means grinding. And grinding I can't do (sortof). But not anymore!

You could do a whole video on refurbishing this to better than brand new. Polished and painted.. Or send it to @TysyTube
v amusing approach to this sponsorship :)

Wow 15000 rpm in the '50's , freaking awesome piece of machinery ☆☆☆☆☆
The Hotrod of your shop imo
Grtz from the netherlands Johny geerts
Now who watches this channel didn't know that he would escalate quickly and disassemble the new tool from the moment the box opened. 😂
I saw the disassembly coming, but the segue to the sponsor segment was a funny surprise.
Him: Now I'm not gonna go too crazy here and tear this thing down to every nut and bolt...
me: 🤨
Him: tears it down to every nut and bolt
me: 😌
"Wipes down fine. Let's polish it on the lathe." 😂😂😂
As soon as he got a new "used machine" I was like Teardown coming!😂
I thought it was going to get a coat of paint too
Shop vac 1/2 full of water with an attachment to hold it right below the grinding wheel will save your lathe from the majority of that dust. It’s too fine to all be caught by the towels. But a combination of the towels and a shop vac will do a better job. The water in the vac prevents any fire hazard issues with the sparks.
New side project, wheel shroud with a vacuum attachment
Indeed, glass ornaments artists use them to get out glass particles all the time.
Beware that this trick is potentially dangerous with aluminum. Aluminum dust + water=hydrogen gas. Leave it sitting in your shop vac, and the next time you turn it on you get a hydrogen explosion.
If possible would a "dust collector" be better than a shop vac as long as you still address the fire hazard?
@@DoubleD132 With a wet cyclone separator? :D
"I won't disassemble this tool down to its nuts and bolts." Yeah right, we know you enough about that. 😂
You don't know me! 😂
Well, he didn't...
I mean, he didn't tear the spindle completely apart to clean the bearings and bearing surfaces, nor did he tear open the motor to clean it's bearings and bearing surfaces either...
I'd say, he only ripped half of it apart when he COULD have gone sooooooo much farther...
Who knows, now that he's fixed the live centers, completely tearing down and deburring/lubing/perfecting the ENTIRE spindle grinder will be the next video...
😄😁😆😅😂🤣
@@InheritanceMachining Would still be a good idea to check the condition of the brushes and the rotor. Best get on top of that now, than later when they're worn beyond repair. If you have enough motors to fix... maybe even consider a rotor lathe. They're really cute and small. ;)
Painting it next video.
That live center drive setup is pure genius.
🤓
Gosh, isn't it. That's a proper hacker mentality: lateral thinking. Absolutely love it.
Rumors say that laptop is still sitting on the garbage can to this day :(
😂😂😂😂😂😂❤❤❤❤❤
lol.
but also 17:05
Wow, 15k RPMs is how fast one of the shafts in the Rolls-Royce Trent turbofan jet engines I used to work on rotates. No wonder that thing sounds like a jet starting up!
What an odd yet appropriate bit of info lol. That sounds like a fun job!
@@squibblez2517 , LOL, gotta love the random knowledge! Now you know!
Yeah, it was a blast. Made some lifelong friends and gained a ton of experience/knowledge testing those beasts.
**Lumineux** - So we sent you a new electric toothbrush to try out, tell us what you think
**IM** - It was great! Got all the oil and grime out from the nooks and crannies
**Lumineux** - Excuse me? Can you run that past me again?
Hehe, yeah, I'd kinda like to to know how THAT marketing pitch went.
"He did what? On a what? ... Okay, but did sales go up? Right. Tell R&D the next model will either be stainless, or battleship gray. And we need to offer brass and steel brushes too."
I mean... It's actually a pretty great use case for a sonic toothbrush
I used similar ones to scrub the painted fabric on a supercub airplane that had flipped upside down on a sand bar into willow bushes… was all green and brown, on white paint…it worked well to get down into the little spots in the fabric weave…
I might be able to convince them of this!@@somebodyelse6673
Daggum...HOURS and HOURS and HOURS of cleaning my M16A2 in the Marines back in the day...and I could have used a cordless sonic toothbrush!
Sign me up!
One thing that makes me keep coming back to this channel is your ability to calmly command attention and explain things at ground level.
thank you 🙏 I put a lot of thought into the explanations
An engineer, by definition, is a person who knows how to use technology to solve problems. It can't be done without teaching, or at least it can't be done well. You can't really know your subject if you can't explain it well enough to implement the solution. Our hero here, is an excellent teacher, despite being goofy as.
@@InheritanceMachiningas a person who recently started working in a machine shop recently(partially inspired by you) i absolutely adore youre channel
Side projects of side projects are denoted by an exponent. Squared, cube, etc. Beautifully done once again.
Ah, there it is. So if it's multi-layered so the exponents get exponents as well?
@@InheritanceMachining I warn against going that deep, but yes. Square your squares if you must. This is inception level side project. Time moves at four times the rate of a typical side project. Tread lightly my friend.
MOM! MOM! Inheritance Machning uploaded a new video. I CAN`T GO TO THE RESTAURANT WITH YOU!!! (Best afternoon experience)
invite Mom to watch the vid with you
@@NickiRusin why haven`t I thought about that.
take video to restaurant, profit.
When adjusting the preload on the spindle, take into account the fact that the spindle and associated bearings will expand when running at 6000 rpm for a while.
good call. If I recall correctly it's sometimes necessary to adjust spindle preloads by monitoring operating temperatures. Too high a temperature means too tight and vice versa
@@InheritanceMachining Axial Preload is also the reassuring answer to your misgivings about applying axial thrust through the spindle bearings via the live centre support when you mounted the cartridge in the lathe chuck for polishing
OK, I've watched further on and you (as I expected) reached the same conclusion, but preload (on machine tool spindles generally but grinding spindles in particular) is not just intended to remove axial play.
With angular contact bearings (and taper rollers) axial preload directly reduces elastic deflection under radial loading.
In other words, snug is not enough: after all play is removed added tightening is required to induce "negative" axial clearance in oroer to produce stiffness in the radial direction.
Anyone interested in learning about this could google SKF Bearing preload for a decent summary, but a rule of thumb which words for practical purposes with these two bearing types is to tighten axial preload sufficiently to cause a temperature rise (at or near the hottest of the bearing pair) of about 30 deg C (40 max) over ambient for lathe and milling machine spindles, and maybe half this much for grinding spindles (unless they're on a heavy machine where you'd maybe go to 75%). On a big machine it might take an hour to reach a steady reading, and that's the one you work to.
Easily one of the more entertaining and educational engineering channels. Also the editing work your putting in these days is top notch! Thank you! 😁
I believe credit for the editing goes to his other half.
Indeed it does!@@derschwartzadder
My pleasure! Thank you for being here!
I'm 2 weeks into an Engineering (technical) course, in part inspired by watching your channel. The teachers love telling us how we won't be on the tools ourselves, so they've redesigned the course to minimize workshop time - as if it were a good thing. I've already got a damn degree in sociology and political science (a.k.a. advanced yelling at newspapers and underemployment). The entire reason I'm retraining is to chase after some of that sweet fulfillment that comes from identifying a problem, designing a solution and then - the crucial difference - making it a reality.
Mech Eng here, the decline in using equipment/machines in today's engineering curriculum is unfortunate. I went out of my way to learn more about it in college, but I've seen people get to industry clueless to manufacturing realities and not realize how bad their designs or prints are since they don't understand what will go into making it. Luckily RUclips is full of great channels like this to learn and grow, especially Brandon's work as he highlights his mistakes and that's when you learn the most. As you stated, one of my favorite things to do is identify a problem, theorize a solution, then create that solution with my hand. Restoring vintage tools in my spare time and building up a nice home shop also helps keep my mind sharp from a problem solving perspective. Good luck in your studies!
I experienced this same thing. No shop classes offered for mechanical engineering. It's resulting in design engineers not understanding machine limitations and tolerances and the price you pay for a fancy 5 axis part that's overcomplicated! God luck to you though. If your college has any clubs like FSAE/Formula Student, this is a great way to get some actual hands on problem solving and machining experience
@@InheritanceMachining no such luck on the formula student front, I'm in Australia studying through our Tafe system, whereas FS (and similar) is typically reserved for our universities. I don't have the math skills to go straight to a degree, so I'm pursuing an advanced diploma as an engineering technician/technologist, with an option to extend into a degree down the track. Conversely, I did a short course in industrial design a couple of years back, and spent about 8 hours a week in a workshop learning all manner of fabrication and conditioning processes.
@@InheritanceMachining Unfortunately, it's more likely we'll see a deeper dependency on automated fabrication QA checking than hands on experience to solve the issue.
@@InheritanceMachining I am in school for Mech Eng as a Tech and we are currently designing and building our own jigs for part production. I am glad my program has a focus on theoretical and practical Eng. When I do bridge over to Mech Eng to finish out the full PEng degree I think I will miss the machine shop time.
Are you aware how relaxing your videos are?
Voice, music, shots, audio, all are very soothing to the ears and eye. Can watch these vids for hours.
And your open approach to your mistakes and box of shame make appreciate my own errors a lot better as learning points instead of failures.
Thank you❤
The phrase, "As my (Grand)Dad used to say", is one of the best. Whenever it's used, the memories well up. Dad never got the tool post grinder he wanted, but this episode certainly makes up for it for me. Thanks for a great video !
They have a tendency to stick with you that's for sure 😁 Thanks!
Man! I just watched all of your videos and I'm begging you to continue with them! It's soooo pleasing and satisfying to watch you making tooling and projects. I can't wait for an update of all the things that have to be done to your small lathe!
Keep up and good luck!
No doubt I'll be sharing everything about that lathe haha thanks for following along so closely!
Yes! The perfect afternoon entertainment is here!
Love it. I scored a beautiful tool post grinder that perfectly fits my old 9" South Bend a few years back. Looked new in the metal case, along with all of the paperwork. I don't use it often, but it's great for those difficult jobs. Love the o-ring drive to true up the live center - very clever design!
Nice! I think (hope) this tool will become invaluable for me. Especially given all the tooling I tent to make (and should have hardened) 😂
I cannot tell you how much your channel means to me, watching you making old tools useful again and engineering beautiful parts. Thank you for your time and the entertaining video inserts. Chamfer on.
Always my pleasure! And thanks for always being here!
Makes his special tools with other of his homemade special tools. All a feast for the eyes to follow. And the guy's humor knows no bounds. Wonderful. More of it. 🤩🤓
When I was trying to figure out your what your picture was, I swore the groove was for an o-ring drive. I've seen similar setups on powered collet indexers used on surface grinders. I couldn't put it together... the hose clamp and "cable drive" are ingenious!
That's exactly where I got the idea from!
Nice build!
I would only make one suggestion ... upgrade your Brake Cable to a double coil spring ... it will eliminate possible coil tension. It's the standard design for flexible extensions for 1/4" socket sets. Plenty of torque in either direction, and perfect flexibility.
Thanks for sharing 🇨🇦
You are a genius!!! The way you transmit movement to the tailstock is amazing. Good job man!
I have my rare moments haha thanks!
Totally agreed!
For additional points in the overengineered category you could have included an oiling port in between the bushings in the tensioning device.
Absolutely right. Repainting that beauty would be a crime against huma...machinity!
😂 Im gonna need to remember that one
5:25 if you give a mouse a cookie...
Hey Nathan, good job on the packaging.
Using the screw to expand the pulley rather than close it is a brilliant decision. Fails safe, won't work loose, and has the potential to be more concentric. Little details make all the difference!
Those are all pluses but the real reason i did that was for a low profile approach since there is no screw head!
I learned many years ago that any UBG (used but good) machine can benefit from a careful disassembly, cleaning, inspection, and reassembly. The big plus is that you now know the machine much better, inside as well as out. Of course, any damaged or missing parts can be fixed or replaced, and any fine adjustments made as needed.
To me, its about the journey. All the side turns and alley ways just make it that much more fun and interesting, edgumacatin' before ya know it.
Actually, hopefully speaking for many others--yes, we really do want to see you take every nut and bolt out of your new-old tool post grinder for a complete rebuild. A number of said nuts and bolts (well, screws) look like they're begging for you to make something new on the lathe. And I'd love to see you match the paint job. It is a nice machine color after all.
MOOOOOOOOOOOOOOOOM WE ARE (voice trailing off in the distance) GOIIIiiing machiiiiiniiiiing
I used one of these to make brass instrument bell mandrels on an old hydraulic tracer lathe! Many sparks, much struggle... Not what I thought I'd ever do as an engineer!
Shout out to Conn-Selmer(Cleveland, OH), the last mass manufacturer of brass instruments in America!
Finally sound effects on the side project counter. I can now sleep at night!
😂 shoulda said something!
I love the attention to detail! Awesome work! This channel has jumped right to the top of my list of "can't wait for the next one!"
Thank you!!
I love when he uses his previously made tools. Like it is all one big story.
A beautifully over engineered solution to the centre grinding problem. Loved it. Thanks for sharing 👍 🇬🇧
Need to sort the cable out though, my OCD was off the charts looking at the tape round the switch. Lovely work as always, love this channel
When I first saw this pop up in my feed I through the thumbnail was a skateboard truck and then was expecting a sick skateboard montage from IM.
Not going to lie, I am a little disappointed there was no skateboarding BUT once again great video! (minus the lack of skateboarding)
that is something you defintiely dont want to see. unless you like watching someone fall a lot is what you like 😂
I thought the same!
amazing work Brandon, happy to see all your live centres in functionally use
Thanks man!
If you haven't seen it already, MrCrispin has a great series of videos on setting up and using a tool post grinder. He used his to regrind the spindle taper on his lathe, as well as all his chucks.
You should build your own heat treat kiln! There are several build guides out there, using lid Co strollers etc. For a few hundred bucks you can build it instead of 2-3k for a new one. I would love to see the over the top machining and construction you would do to the housing :D
Dumore post grinders is still around. They go for approximately 3200$ - 4000$ 1/2hp to 3hp
We had the same model Dumore Tool post grinder. We even had an extra long spindle for I D grinding. That one spindle was like close to 10,000 dollars.
Like you said, that tool is a game-changer. Congrats on you new acquisition.
All the possibilities 🤯 thanks
Hand Tool Rescue would be very happy with your work on that grinder.
the solution to drive the live center just blew my mind, so smart !
I knew it would escalate to a cleaning frenzy and it was absolutely the right decision
You'll see what is a cleaning frenzy once he has to clean his lathe! 1 min of toolpost grinder use, 10 hours of lathe cleaning (that's using towels and rags).
My two favorite RUclips channels for machinist work. CEE Engineering and Inheritance Machining. Both are top notch.
I just picked up a slightly smaller Dumore tool post grinder in much the same shape (wood case instead of metal) for $40 at an auction. About to do the same tear down/clean.
Please replace the power cord and switch!!!!!!!!!!!!!
At the minimum get some heat shrink tubing and replace the electrical tape. I hate electrical tape as it leave a gummy residue.
Thank you for your continuous healing content. It has helped make the engineer our of me i have always wanted to be. Scientist even ❤❤
Love your Ads. your sponsors should be proud.
Apparently the trick to carbide parting tools is to run the workpiece as fast as you can and take a really heavy cut, your colleague Clough42 recently did a video on this.
I don't watch Clough42, so I don't know what he did. I do know most people I see on YT do it wrong on a manual lathe.
Parting tools are like any other tool, they need to be run at the correct feed/speed, which can be pretty hard to do manually. I always power feed mine at the same feed that I would face a part. Carbide inserts need far more tool pressure than HSS, so they are next to impossible to feed at the correct rate with out turning the RPM down way to low.
Your work is inspiring. You don’t sugarcoat shit at all. Thank you. Great video as always 😅
😁 thanks, Terence
Sugarcoated Shit…. Worst 1970’s breakfast cereal ever! 😂
Every IM video: *_IT'S OUT OF ALIGNMENT_*
What can I say... I commend your patience.
😂
You have a real gem there. I worked for the Boeing company for 13 years and as modern as our shop was we still ran a LOT of old equipment such as tool post grinders, trur trace units on our Bridgeport mills etc and after years of use still would get the job done. That man was super nice to let that grinder go so be sure and properly thank him. Good job on the refurbishment...
Very good video brandon..thanks for your time
Seeing something made in the home town I was raised in is a bit bitter sweet
I’m happy you’re getting use out of it and hope it serves you well
And it was most likely made in the 50s/60s
Racine went to shit in the 70s
DuMore is still in business, but I don't know if they are in Racine still.
@@InheritanceMachining the Racine location closed in the 90s unfortunately
They are still up north in Mauston though
I saw that coming.
Opening the door with your foot was so impressive
😎
Wow, your classes are a joy to watch. thanks
first new video since i found your channel!!
"I'm not gonna tear this thing apart just to clean it"
Proceeds to tear it apart just to clean it.
Another amazing addition to your library of videos🎉
No! You cant just drop a video simultaneously with "I did a thing"! Now i dont know what to watch first :)
no way i had the exact same problem
Next time please just cut down the sides of the box and fold it away. I felt like I was about to watch someone die as you were trying to kick that empty box off the table
I'm looking forward to seeing how your shop grows and changes over the years. Hopefully there's decades worth of material yet to come😊
Man, I gotta tell ya, my OCD loves it when a machine tool is rotating and you literally can’t tell #zerorunout #ifeelsoalivecenter
Loving the mix of machining and new tools lately! That is one beautiful piece of machining history
I love seeing old tools get a new life. Love all the side projects you get into. Awesome job!
I really appreciate the unique themes of your videos and the high craftmanship!
The memes run hard on this one keep going man this is fing awsome
Loved how you drove the little centre turner dohickie! Very clever. Great video 😉👏👏
Thanks for sharing your knowledge. I always learn something. When setting the spindle on my tool post grinder for height and square I set the spindle between centers on the lathe and tighten down the tool post clamp on the grinder. Quick and accurate on two planes.
Sunday morning here in England , just walked off my full Irish breakfast with the dogs , coffee, inheritance video ,sweet.always feeling the level,of satisfaction using that rotary fixture and those trick old skool hot rod clamps . Wonderful.
One of the greats on youtube, great work sir. I always enjoy these videos when they come out.
Wow! This one of my mostest favoritest videos so far! Thanks!
yay! new video! in the past week, I've gone through and watched all of your videos till today's. I enjoy your content very much👍
It's best to run it and warm the bearings up before setting end float or preload. I've seen the spindle bearings in a freshly rebuilt machine seize as the end float was set by intuition when cold and as it warmed up it became zero
As always an amazing video. It’s so inspiring watching your channel grow. Thank you for everything you do and inspiring me.
It has been a joy watching you grow.Well done.Snafus and success.
Way to go Nathan! Thanks for sending this over because we all get a cool video to watch because of you!
Have we given praise to the fantastic closed captioning of each video?!
I just love the descriptions of sounds. :)
Man, this old machines are something else. Things made in the 50 to 70's are beautiful and have a especial vibe. Or Maybe is just a nostalgic thing inside me
Congratulations for your new tool addition. Nice thinking using the cable you did to drive the secondary spindle. Thanks for the video and please keep them coming.
I just want to say thank you so much for sharing this fun hobby and allowing us all to engage in friendship with you. You're a special person and your skill, humor, and sentiment all make for outstanding videos. So thankful I started watching your channel. All the best sir.
Greetings, in my spare time when I rest after work, otherwise I am a car mechanic, I watch your clips, not that they are good but they are therapy, your dedication to every detail, I just watched 3 clips in a row and I have to reduce it to one a day because soon I will watch everything and be me wrong because I won't have anything to look at anymore, there is some magic in that iron, or I find myself loving the same thing, which is that a man creates something with his hands, it feeds the soul. I think that people today are unhappy because they don't know that feeling that we have, we artisans, turners, mechanics, good luck in life and work, long live
Watching you disassemble and sort out this tooling - just magnificent. 👍
Such a satisfying project. I’m pretty sure I’ll never be as good a machinist as you’ve become…
1. I don’t need to be for what I do
2. I don’t have the background in math
3. You have a gift.
But thank you for contributing to my education, and in a highly entertaining fashion!
You are amazing on the rotary table!
You built it to be synchronised with the way your brain works and it shows!
funny i never looked at it like that but you are right! thanks
Thank you Nathan!
Best engineering channel (best overall channel in my opinion) on RUclips. I look forward to every video that's posted and often re-watch old videos instead of hunting for other channels.
Nice solution to driving the live centre, and very well made.
NONONONO
This guy cannot just gloss over the fact that he just opened A DOOR KNOB with his foot!
Yes, I see how you did it and now I'm definitely getting myself a pair of boots
As always, well done. I really like your style. Thanks for sharing your time and talent.
Actually a good sponsor mention. Want one.Why don't they make grinders like this now. The bearing preload mechanism is genius.
I love that your side projects and tools all have such a high finish. Clickspringesque!
Love this channel, always get double the content- first time falling asleep to it, second time watching it (and sometimes a third time for fun)
Being a machinist for 20 years, I understand your enthusiasm as I worked with these. 😀the quality of machines made in the 1940's-1960. I still love the older equipment!
Man, this 30-minute video was over so quickly. I could watch your videos for hours and not get bored at the slightest!
i absolutely love the into song its sooo calming
