"Keith's Home for Wayward Machines". Love it! I am both educated and inspired by everything you do - I enjoy your channel immensely.
A cracked wheel is No Bueno! One one of the grinders we rebuilt we had a 60" x 4" wide wheel that an apprentice accidentally dropped an inch or so during handling, and didn't mention it to anyone. When the operator switched wheels back to the mishandled wheel, when he spun it up and started to dress it in, the wheel exploded and damned near killed him. Broke his jaw, gave him a TBI, broke his arm in two spots, and this was after destroying a 1/2" steel shroud....
Too bad you had to publish your apprentice mistake here, a mistake happened someone got hurt , don’t need share with the world
@@dundasjunctionmodelr.r-jam8267 what's the issue? he didn't name the apprentice.
its important to remember that an apprentice is not going to be as knowledgeable about safety issues that an experienced operator would. this could be a good reminder to someone reading that post to educate/re-educate those that are working with grinders about how dangerous that wheel can be and that if there is any handling problems, to have the wheel checked before put back in storage.
@@Jackhammer909 no issue really just did not think this was the place to discuss the mistake , deal directly with apprentice no where else in my opinion
I may have mentioned that I am an eighty year old retired mech engr. I love watching you work! I'm basically a hobbyist woodworker, but love to see how the machines that I used to use are made by the machines that you restore. All in the interest of industrial capability that we all cherish! -Curt Kuhns
Keith, if you can rent a small oil purifying centrifuge, it can clean up the oil. In the old powerhouse, we had a large Alfa-Laval on a cart, for our compressor oils. They do make smaller ones now days.
Might be cheaper than oil replacement.
Best wishes from the far North.
I know lots of your viewers have extensive knowledge on these huge machines, but for those of us who don't, I really appreciate how you explain what they do and how they work, as well as what you'll need to do to get them functioning properly again. Surface grinders were mostly a mystery to me before watching this video, and now I feel like I can see just how vital they must be for certain projects. Here's another series for me to follow!
Aren't we fortunate here in Australia to have electricity supplied in 240 V single phase and 415 V three phase, no big complications to deal with. Congratulations on your new addition to your shop. Ray.
If Keith was a business, it'd already be 3 phase power. We only run single phase to homes in the US to save money because only people like Keith need 3 phase power.
Most homes here in the USA, at least those less than about 50 years old come with a number of 240 outlets for air conditioning, or have them added during the lifetime of the home. My home was built in 1925 and has 400 amps of 240, and I’m in New York City, not out in the countryside.
I'm Australian and 3 phase power only gets run to places that fork out the $$$$$ to get it, I wanted 3 phase power here and it was going to cost 30k so I bought a cs Lister diesel clone and belt drove a 3 phase alternator from that.. I run it on waste oil so it costs me nothing for fuel
@@graedonmunro1793 your lucky, it's a real pain having to start a generator all the time but I just couldn't afford the 30k the power company quoted me to put in 3 phase here.. out here the power company charges you for the transformer which they then own and they charge 2k to upgrade the pole to one thick enough for a transformer and then I'd have to pay for the 120 meters of cable too all so they can sell me power at ridiculously high prices.. the transformers cost the power company under 1k and they sell them for over 15k
I'm from South Africa and we have no power here 😂
MILLWRIGHT good morning I’m a nuclear Millwright out at the Hanford site in Washington state. Was raised by gyppo logger in Northwest Montana. For your hydraulic oil the 60 gallons of hydraulic oil ,you can go old-school and run it through a gravity feed through waterfall type system through rabbit hair felt and clean it up brand new. Or you can get a small. centrifuge and run it that way. The oil isn’t wore out it’s just dirty. It’s not like engine oil that you actually smash the chain links apart in the molecules. It’s just dirty. Go in peace, my friend, and serve the lord and all that we do
More toys! Wow!
Let me guess, Keith. Your spread down there in Georgia is 20 acres and 15 of them are your machine shop.
I have to think long and hard before purchasing a lowly hand plane, so I am constantly surprised by the steady march of these monster machines into and out of your beautiful shop, Keith. More power (220 or 440v) to ya!
I used to work in a machine shop that did steel/aluminum/paper mill support and wecalso rebuilt cylindrical roll grinders and lathes. Our cylindrical grinders could achieve better than a 3 microInch finish. It was so smooth that it was no longer a mirror finish, but it was actually black due to destructive interference because the finish marks were smaller than the wavelength of light.
Landis, Mesta, and Morgan were the three that were most common.
If only you were much closer to Brisbane Australia, I'd be in there in a flash on the 19th.
Nice find Keith. The grinding shop that I have used over the years restoring woodworking machines has a Thompson surface grinder that looks like the mag chuck is about 4 feet wide and about 10 or 12 feet long.
That is a very nice surface grinder. I also have an iron deficiency. I was hit by an SUV a few years ago and my tibia plateau was ruined. Since the accident I became anemic and need iron infusions twice a year. $768.00 is the approximate cost for 60 gallons of plain hydraulic oil.
Keith's Home For Wayward Machines sounds like a place I'd like to live.
I really like the "new to you" grinder Keith!!! I know when you get through it will be like new.
Thanks for carrying us alone on this build.
Looks like a great project Keith. Will be fun to follow you through the restoration.
Thanks for sharing.
Wow! Seems like a massive job to me. Can't wait to see you restoring it.
You could try using patience and gravity to separate the ingredients in the oil. Run it in a barrel, and leave that untouched for a week or so. Then drain the oil from the center. If you happen to have a vacuum pump, you can further degas the oil and let the water boil out. Then run the oil through some very fine filter cloth, and it should be a lot more usable.
Thank you Keith! I remember when you got the Landis grinder, repaired it, and went to work! My old cat Bailey loved to watch your videos of grinding - he was fascinated by the sparks.
On the subject of the Cat's Meow, we haven't seen the shop cats in a while.
I was absolutely rolling at your opening comments. Thanks for this great start to the day!
Wow 60 gallons! It must use it for ballast and vibration damping
I'd love to come and join you Keith - but popping by is a bit out of my way over here in the UK! Hope you get a good gang that can get that grinder looking good!
I too would like to help but I am also in the UK (north east). Good luck to you and your interns with the rehabilitation of the surface grinder, I have a similar project but only 20 X 10. Thanks for this and all of your previous videos, you are helping keep the industrial history alive.
Keith, you are so much fun to watch.
That looks like a worthy addition to your shop. Congratulations
Great machine. Ran one for a few years and it always worked flawlessly. Even in the cold winters here in Canada, just let cycle away for 30 minutes and warm up and it was fine.
Very nice Heavy-duty Thompson grinder.
Really some great potential.
Thanks for sharing Keith.
if i lived closer, we are in Northern Nevada, i would help out for sure!!! thanks
I look forward to seeing your next video on this project. There’s never a dull video on your channel.
Kieth has a new toy. This will be interesting watching being restored.
Great new machine for you Keith!
I would be more than willing to come up for a weekend I am down in Tampa but unfortunately I barely have a vehicle that gets me back and forth to work but I'm sure you will draw a crowd thanks for the videos
It’s always bittersweet catching the beginning of a new project. I’m so eager to se the next videos in this project
Keith, might save a bunch of cash getting the hydraulic fluid “polished” by a third party. They connect the fluid to a machine that circulates it and takes out the dirt and any water. Not a final solution but good for a few years
If the oil is cleaned properly and hasn't been burned, the oil will be good as new. Oil does not wear out!
Congratulations on the upgrade! I hope it checks out to be ok. I think your transformer solution is the correct way to solve the problem . It’s difficult to find anyone who will rewind a less than 25 HP motor these days and if they do the labor costs make it too expensive, less money to find a new replacement?
Now he will be keeping the original configuration and will have a 440v supply if he needs it for something else.
It is great to see you happy (and funny) thanks to this find ("iron deficiency disease" indeed!) The transformer sounds like a win-win, less money, retains the original configuration, and you will have a 440v source for powering or testing something else. 60 gallons of hydraulic fluid! And the coolant tanks seem to work like septic tank separators. Good luck with getting it back into productive operation, I wish I was close enough to help!
I have rebuilt a number of machine tools and had similar issue with 3 phase electric motors with only 3 wires coming out in junction box. I easily fixed by locating the Star connection on the end of the windings, usually under the cover opposite the output shaft of the motor. Separate the connection and solder on extension wires to each lead. Insulate new connections properly and bring the 3 new wires out through the junction box. Had to do this so could run motors on a VFD which require Delta connection. Just a thought if the coolant pump wiring is the only reason you are looking at a transformer. Been running my machines for years on VFD after doing this and absolutely no problems. Cheers love your work.
Congratulation tremendous addition to your shop
You might try filtering and heating the oil to over 212 degrees to clean and boil off any water. It would be alot less expensive than changing out the oil.
had the same model, bought it a couple years ago for scrap- think I pad $45.00 for it off a ford plan closing their tool room. Loved the grinder, worked very well and was amazingly accurate considering its age. built like a tank
Congrats on the new machine. Looks great and I'm guessing you will go over it with lot's of TLC...
Should be a wonderful addition to the shop.
I can see a future project in the offing. 👍
Very nice,great start for new project.kudos 👍👍👍😎😎😎
440-480volts is a different beast, as an electrician for 40 years have seen many injuries and some deaths from this higher voltages on machines. Please be careful on hot tracing and troubleshooting.
That's a very good quality surface grinder, ran one exactly like it for many years.
where I worked my last years I was in the tool room and one od my machines was that same grinder dis a lot of work on it.
Good morning
That's a nice grinder. I'm not sure if I can make it but I will look and see. Wish I had the viewers to put out a request for a workday. I have two machines I could really use help with. Great video as always.
Excellent choice on the transformer. I've a DoAll that I run on a Phase Converter and and transformer to make 480V 3-Phase. Works great!!!
Kieth
The kill kennel needs help… I can imagine how sweet a Devlieg 3B48 jig bore would look like in your shop. Mine is headed for a scrap yard. Free to anyone who can move it.
Nice!! I hope American Rotary can step it up for your volts- I know if i ever get a sweet shop like yours, I'm calling them first so i can power everything up. Hope to see the Thompson in use soon 😊
That’s gonna set back jimmy’s band saw back another year
What a gem, my B&S 10x30 is amazing. Problem with grinders is you always need a bigger one. I’m hunting for 24x72ish always now.
Make sure you always have a 6x18 though.
that America has so many different voltages in the power grid.
In Europe it is 230 to 240 volts one phase. Or 400 to 415 volts three phase. Three phases are very common.
For the small variations, no transformer is necessary. Even if it's only 220V / 380V.
That’s an interesting machine. I am looking forward to seeing you refurbish it.
May hands make quick work. Keep up the good work Keith.
Keith’s home for wayward machines 😂you should turn that into a tshirt
I have two as well. Looking for another home. Nice production ones. My Table moves up and down and the head is solid place. Wet or dry. 2/3 sized that. On 4x4 heavy pallet. That looks nice. Lot of work to bring it back. The Mag Chuck is like a 3-jaw nice to have. Mine are 370v (Lighting voltage? ) 3-p. I generate myself. The bed is the work surface. That looks like a very nice clean mag chuck.
Thanks Keith for the video good job. Keith Dalton WV4G.
Looking forward to your journey with the grinder. A similar grinder is certainly on my radar, but haven't found the right one yet. Seems anyone with one for sale thinks they're made of solid gold 😮
Always a great video thanks for sharing
13:00 "APPRENTICE MARKS" - Love it :)
Keith, lovely machine. Love to drop in and help out but its a tad far to come for a day or two.
Oh and AUD/US dollar is horrid to so it'd be way to dear to travel.
Looking forward to the recommissioning!
Keith, instead of getting a big transformer to step up voltage for the entire machine you might consider keeping the majority of the machine as 220v, and only use a smaller less expensive step up transformer to power just that one motor that requires 440v.
Keith have just finished a no. 5 Brown and Sharp surface grinder still has war paint . 1940 Era 24" chuck
Good Morning Georgia!😊
what an amazing *_beast_* of a surface grinder! 😎👍
Almost identical to my Thompson
Great video...the one who dies with the most toys wins.
This will be a nice upgrade, once it's fixed up.
Keith, I worked in many machine shops and I have to say I've never been privileged enough to come across a surface grinder of that caliber. Now I don't what story you told to your wife to agree to allowing you to purchase such a machine like that. I bet you have all the qualifications to go into politics. But that automatic stone surfacer is just going to far. The question I want to know is, does that machine have a cup warmer on it. I hate it when my coffee gets cold. OK can't wait to see when you put that thing to work. PS machines only rust when you're not using them enough!
Thanks for sharing
I wonder if the hydraulic fluid in the new grinder is mineral oil. If it is, Keith may be able to clean it up and reuse it. It doesn't wear out.
Actually, oil never wears out. Doesn't matter what 'flavor' it is. It just gets full of contaminates. If you don't burn it, you can clean and use it forever.
My OCD would require me to take that down to nuts and bolts and do a full restoration. Nice machine.
You do not have OCD......trust me!
Kleptoferroitis is incurable. Fortunately there are many avenues to relive some of its effects.
Hahah
Look what followed me home.
It’s gunna be interesting. I’ll bet you’ll be pleased.👍👍
Nice new toy Keith
Hope y'all got a good deal on this. Quite a fair share of rust.
Keith, do you know the manufacture year of your new grinder? St Marys, GA
60 gallons? I do acrylic court surfaces and most of our materials come in 30 U.S. gallon drums so I have a good idea what a pain getting that much hydraulic oil will be to handle but it might be easier to get the that size and a hand pump to transfer the oil in than 12 20 litre containers that you have to lift and pour.
Thank you for sharing.👍
I wish I lived closer.
I was working in an aircraft job shop and had the exact same surface grinder. They hired this guy that was supposed to be a "cracker jack". He had a 12" dia. part that needed .0005" taken off the top surface. They were supposed to give it to one of us but gave it to the "cracker jack". He's grinding away and all the sudden we hear a grrrr. Come to find out he when he was rapiding the wheel back he bought it to the end of the travel and it banged making the head drop about .003"... word to the wise never rapid the table all the way back if you do when you come close to the limit make sure you start feathering the handle so the head speed creeps until almost at the limit... PS. At least on that machine the wheel dresser never dressed that wheel straight. Always use a diamond on the table always undercut the back part of the wheel also!!! If you put a new wheel on balance the assy. Then install it on the machine dress it balance it again then re-dress it and you should be good to go!!! You would be surprised how many donut makers don't know how to properly run this grinder!
That is a very lucky machine. 😊
Hi did you give up on the Monarch lathe ?
I worked on a mechanical magnetic chuck that didn't operate properly
I’d love to have one. i have no idea what I’d do with it, but I’d love to have one
Just clarifying the procedure below allows motor to run on 220v and not suggesting you have to use a VFD
I'm getting a 32" surface grinder later this month, hopefully it doesn't take 65 gallons of hydraulic oil.. if it does I'll be trying to work out how best to clean the oil instead of just changing it, 65 gallons would cost about 2k here in Australia which is more than the grinder cost.. buying a few 12" wheels will be expensive enough without adding the cost of a oil change
Poor orphaned machine followed him home again.
Keith have you thought about opening an ARN museum?
This machine has one flaw. The head slides are wide open and grinding grit goes into them and causes premature wear. Too bad they didn't come up with some type of wipers or accordian style coverings for the head ways.
60 gallons crikey! Nice machine though.
i gotta find a way to build a small version of that... though... for a project, a long bed, width capacity maybe 100mm max. a bench grinder might be converted to do the job, finding a one piece rack to drive the table might be a struggle, considering the length i would want.
Keith I would love to come help just too far. Idaho to Tipton is a stretch. love your content learned a lot from you. Did you finish the press?
Hydraulic oils don't get the same abuse as engine oils, they can take up dust and moisture from the air, and if you can take it out get it to water separate and hen run it through a 10 micron filter it should be as good as new. At least according to what i read on the forums on the internet. One guy talks about the hydraulic oil in a system where he works are over 40 years old and still good. 60 gallons is a chunk of change, so throwing it out if it is still good is a waste. 50 gallon drum is 6-700 dollars...
An inexpensive treatment for IDD is Geritol. 😊
Looks mint 😊😊😊😊😊
18:00 Why couldn't you rig up some sort of filter system and try to filter the existing hydraulic fluid? Obviously it wouldn't be as good as completely replacing the hydraulic fluid, but it would be extremely inexpensive. You could just get a 55 gallon drum and pump the existing fluid through a stack of coffee filters into the drum, and then reverse the process and pump it through another stack of coffee filters back into the reservoir. And if it still looks crappy and cloudy, *then* throw it away and replace it. But if it were me, I'd at least give it a shot.
