DoAll Milling Machine motor and Big Press Repair.
Вставка
- Опубліковано 16 жов 2024
- This week I get into repairing several things in the shop. We weld up the control handles on the Doall milling machine along with pulling off the electric motor for new bearing. I also repair the large press and use it to remove the motor bearings.

Maybe I've said it before, but you Saturday morning videos are what I watch in the same way that I watched Saturday morning cartoons as a kid!
for me it was Sunday morning watching New Yankee Workshop and then this old house lol
I would watch the static screen until the start of the broadcast. The national anthem was the first thing.
Gotta love ole Steve, a good man , and a man's man , few and far in between
Dear Steve Summers, I am astonished, nay BLOWN AWAY ! You are an AMAZING FELLOW. Your workshop is a thing of beauty .
Watching you all these months beavering away, was an awesome experience; seeing you - finally ! - busy in your own 'shop is quite a privilege. I have run out of adjective. A HUGE praise goes to Mrs Summers herself and her obvious support for you and
all the rest of your family and your friends. Well done, my good man ! Cheers, all the way from Down Under.
Thank you😁👍
There is nothing more satisfying than fixing up old machines and them working properly again
Best attitude ever my friend.
ya i did my snow blower last winter then we didn't get any more snow haa haaa
I think I watch channels like yours as much to learn of the existence of new machines, or new versions of machines, that I never new existed until I saw them here -- as to pick up an tips or shop tutorage.
What a video. Fork lift repair, chain fall explanation and repair, motor bearing repair, hydraulic press repair, and three crazed squirrels jumping up and down in a cage.
Enjoyed the video and thanks for posting. I had a lady friend admire all of the tools I had in my shop and ask what they did. She later said," If you got the right tool, you can get the job done." She then gave me a smile. I agreed .
Hi Steve being a retired machinist I really enjoy watching your videos. In your last video you mentioned that the tire on your electric and truck was coming apart . Back in the 1970s we had the same problem with one of our electric hand trucks . To fix this problem I took a piece of well casing a little larger than the OD of the tire and placed the hub in the center of it after cleaning it . I then poured liquid Devcon into it and let it set up . The next day I pressed it out of the casing put it in the lathe and turned it to the proper OD . It served us well for several years after that .
Always one of the highlights of the weekend when a new Video comes out!
ya here and Mustie1
Very healing episode. Mill controls, chain lift, tire, press and the mill motor bearings; did I forget anything?
evaporust........taking apart old tools and machines.......repairs.......montage fast footage with music.....hand tool rescue would be proud.
Nice to see you again back into 'repairing things mode'. You look a lot more content. That DoAll mill is good for you as it gets other things repaired.
Good to see the new batteries in the VHTWB (variable height transportable work bench). A great piece of kit for any workshop.
Keep on keeping on as it seems as if you will provide us with a few months worth of interesting videos.
Keep safe!
18 is such a special time in a youngsters life. My son is also 18 this year.
That tire repair kit looks sweet, I'll have to check that out. Congrats to your daughter, tell her I wish all the best! Thanks for the video Steve, it is always a pleasure, take care!!
Great work! A true maintenance mechanic at work!! Things are starting to come together in the shop, in a great way. Wish that daughter a Happy Birthday for me. Hug her and love her all you can while you still have her at home. My little girl is now in her early forties, and busy with her own family, and career as a Family Nurse Practitioner. They do grow up fast, and then they are gone. Stay well, and stay safe.
Will do Vernon. I have a hard time believing it has been 18 years. Thanks for watching.
fun week in the shop! thanks for sharing!!!
Well Steve another great video. It’s time for Saturday morning coffee. What a great way to start the day. The back of my truck is full of old,tools and equipment from a deceased owners garage. Sort, clean, and prep for either swap meets or use in my small shop. Great fun but lots of rust, crust, and desert dust to remove.
Happy Birthday to your little girl. I've got one almost 18 myself, to you they're always a little girl it seems no matter how old they get.
I had to smile watching you jump with the press and bearings. No matter how many times we do it (unless you do it all day everyday) there is at least a good flinch when they pop. I've had buddies put air between their feet and the floor on some really tight stuff, expletives and denials of staining their shorts etcetc... I recall many of them every time for at least a smile. Thanks for sharing
Good man Steve. You're flat out. Happy birthday to your daughter. Regards from Ireland.
So cool to see you finally back to working IN your shop instead of ON your shop. Congrats on your progress.
Very full episode this week, enjoyed Steve.
I just love your signature song. I would like to get a copy of it.
Isn't it always the case, you have to fix a tool to fix a tool....😂😂😂
Give her a Happy Birthday from Calgary Alberta.
Watching you put those roller bearings back together reminded me of an old funny saying: "I like my peas with honey, I've done it all my life...It may sound kind of funny, but it keeps them on the knife!"
Steve,
Who made your motor? It is a well built motor. I taught an electrical class to 17 homeschool boys, and this motor would have been an excellent example to disassemble in class. The conductor bars that set up the counter EMF through the zinc end plates are so clearly evident. In motor terminology, the motor is not "sealed". It is "totally enclosed fan cooled" (TEFC). The heavy casting is to radiate heat via the casting fins. Ambient air is drawn over the motor via the fan to facilitate heat removal. Open or drip proof motors draw cooling air through the motor carrying ambient filth inside the motor. Dirt is still an issue for TEFC motors as it blocks air flow and even insulates the motor casting. Early motor technology relied on massive castings to absorb and radiate heat. Modern technology relies more on heat transfer. This is one reason why very old motors are so much larger than their modern counterparts.
Early in my motor training I was taught that greasing motor bearings is the fastest way to wreck a motor bearing. The issue is that motor bearings not having relief ports can easily be blown apart. Grease gun pressure will easily blow out the shields or seals and heated grease won't be contained. Decades of motor maintenance tended to confirm that motor bearings are very resilient. I saw bearing failure due to lack of maintenance, but I also saw decades of industrial use with no maintenance and no bearing failure. Possibly my instructor made a valid recommendation.
If you are buying bearings from a bearing house, just give them the numbers on the race. There is rarely any variation included in the motor number. Bearing class is only an issue when replacing precision bearings. Bearing numbers are universal or easily cross to equivalent. Your motor bearings are common single row ball bearings. Dimensions are a fine method to size the replacement, but size doesn't describe design characteristics. Bearing numbers include design as well as size.
You do need a good set of bearing pullers. I was curling my toes while you used pry bars!
Another H frame pressing option is to use heavy pressing bars to span the frame width and choke up with thinner stock like you did on the recessed cross frame weldment. I employ bearing splitters at this point as they are very thin to clear to the back side of the bearing inner race and are manufactured with fabulous strength. I have never damaged a high quality bearing splitter. I always press across the splitter frame and not on the spreader bolts. I also cringe when I see mechanics press with a puller jack screw directly against the end of the motor shaft. The divot in motor shaft end is not intended to accept the tit on the puller screw. This is the center for machining the motor. If the motor ever requires rework, the machinist won't be happy if the mechanic wrecked the shaft center. Always employ shaft savers.
Your motor is designed for this application. You won't find an off-the-shelf replacement. Foolishly employing bad mechanic procedures can quickly get very costly.
Thank you for the chain fall teardown. I have never been inside a chain fall. I will soon move my 3 ton H.O.K. inside. It has served me outside for 15-20 years and it no longer "locks" and holds the load. I have had no other choice that to leave it exposed to the elements. Evaporust may be my first step to salvage a once pristine hoist. I will cry if my abuse has wrecked this hoist. I suspect that it is older than me (65).
It's always like hanging out with a friend at the shop, when a videos frrom you comes out! Thx a lot!
:-D
Nice to see machine work again
Nice easy going video for my Saturday morning. I admire the way you come up with ways to handle heavy and awkward items without help along with of course your broad range of skills. And happy birthday to your daughter. They grow to adulthood waaaay to fast. CU next week.
I really enjoyed the classical music at 15:00 with the fast motion teardown.
You inspire me Steve. Fix a tool to fix a tool, then find the tool to fix the tool. Hardest part is getting started. Happy 18th Birthday Miss Summers.
So I am not the only one that experiences the "Domino" effect. That effect is where you have to fix something to fix something else to fix what you originally started to fix... Amazing how many times I have that domino effect happen to me. Thumbs Up!
That's shop life. One project leads to another. Before you know it you're buying tools to fix your tools. Or making them.
Could not ask for a better way to start my Saturday morning. Thanks, n have a great time with your daughter n family. They grow up so fast.
I wish I achieved 10% of what you do in each week, Steve!
Great video - fixing tools so they can be used to fix tools to fix everything else, I love it - old school American resourcefulness at its best. There was a time we didnt automatically throw things away we fixed them because many times we had to, good to see a bit of old school thinking and saving money doing it as well.
Saturday mornings will never be without the visits here with you my friend. I bet you drove your mother into a tizzy when you discovered your first screw driver, LOL. I did the same to mine. If I found anything I could take apart so shal it be. One day my dad came home to me and his treasured Lawn Boy mower disassembled and me trying my best to get the piston back in the cylinder with no ring compressor. I believe I was 5. Dad just said to give him a couple min to change his clothes and he came back and showed me how everything worked. I had that mower apart a dozen times after that, LOL. Still today at 65 I am like you taking things apart to see how they tick. Thanks bud. Take care and all the best to your 18 year old. I bet she is as pretty as your lovely wife.
Another quality Steve production - thanks for bringing us along.
CM hoists are very good quality! Should last for decades again....
That closing shot of your shop really hits home how much more spacious it is.
And having natural light always makes things better!
(I worked in a basement under florescent lights in the '80's. In winter i never saw the sun)
What a great way to start the weekend. Working at your workbench with an exterior view would be a real treat. Probably wouldn't get any work done just looking out the window. Have a great week.
Thanks Steve. Always end on a cliff hanger.
Great to see you repair things steve. The world has become a throw away place so it always good to see people who are repairing things.
As for hydraulic pumps. Look at ENERPAC pumps.
I try to repair things all the time. Sometimes I win and sometimes I lose. But least give it a shot.
G'day Steve. Love that big hydraulic press of yours. I bet you're glad that it's up and running now. Your shop is coming along nicely Steve. Cheers, Aaron.
Enjoyed this episode very much. But I always seem to enjoy watching your videos. Thanks very much for sharing.
Well, thanks😁
It's nice to have a lift around the shop Once you have one.
Nice to start Saturdays off in your shop.
Take care
The art 🖼 of the fix. Thanks Steve!!!
Really enjoyed Elizabeth's virtuoso performance on the violin. Great video, as usual, glad to se you getting back in to some machine work. Your shop is starting to look really good. You deserve it after all your hard work, not forgetting your able family and friends assistance. Good luck and thank you.
Wish your daughter happy birthday from the UK 😀
Ain't it always the way...gotta mend at least 2 things on the way to doing the job you started out on! Good job getting more tools sorted out.
That's the way it seems😁
Steve, keep your videos coming just the way they are. I look forward to them every Saturday morning.
Nice job, I'm new to all this and you make it very easy to understand. Congrats on your daughter's birthday. I hope you have some special planed for her. Thanks again.
The shop is looking good, great to see it working again. Well done!
I was looking forward to seeing the drive wheel of that lift get removed/replaced. Did you forget to include it in the video? Love your stuff. Thanks for sharing with us!
Great content, your videos get better all the time.
I had always wondered how those chain hoists worked. Thanks for showing us the fix!
It nice to see that I am not the only one that has to spend a day fixing the tool that I need to fix the other tool that will fix the problem :-). Great video!
Nice work on the motor Steve, In my trade HVAC we deal with motors of all types on a dally bases. I've changed hundreds of bearings, and have experimented with different methods of extending bearing life, but nothing worked better than just buying a good quality rubber sealed bearing and just leave it alone. Remove and plug the grease fittings and mark it as "sealed". The suffix on the bearing part number usually ends with something like this -RS , -2RS "RS = Rubber Sealed". Hopefully this helps someone out there...
You are onto something there.... I have a similar Powered Lift Stacker (Vestil brand). I stopped at new house construction site near me and bought a scrap piece of inch and half sub-floor plywood and made some cleats to lock it onto lift forks after cutting it down to 3x4. When needed, I lay it down, stab it and have a mobile workbench/lift platform wherever I need it.
I think you'll find that when you have some weight on the chain-fall the down cycle becomes much easier.
So I'm the guy that has the same lift as you... Get the front ones too. The idler wheel in the back (there are two wheels in the back BTW) will survive pretty well, but the front ones will die shortly after the steering one. The new wheels that I got for mine were red, and made of a harder compound than the originals, which literally dry rot away. Also, always try to avoid steering without any throttle application, as that really abbrades the wheel if your floor is rough. BTW, they are a real joy to change. Find someone with a liftgate on a box truck, and leave the tail hanging off the edge while you use tie-down straps to hold the forks down to the gate.
As much as I liked the shop rebuild, it is great to see you machining again.
Good video that Steve, as for next week I’ll hazard a guess at the Do All saw. See you next week. 👍
Exceptional progress this week. Happy birthday to your daughter. Quite the milestone
Good mornin'. It's good to see you working in the shop again, fixing stuff. I so enjoy watching your videos. I might have a project for you sometime. I need a gear with a matching worm. I will email you with the details when I get ready. Have a great week ahead.. Thanks.
Thanks Steve. I have 3 of the chain falls in my shops. Excellent material for a video. I always love videos that are unique and not copy cats that everyone does over and over again. Thanks again.
Shops looking really good Steve, nice to see you back on the lathe doing some engineering!!. It’s good to have all that room to move about in and the equipment you have acquired is really coming in handy. The shop looks to be really light and airy, when you think of where you come from over the last twelve months, it really is some achievement!!
I noticed you have a Black Diamond drill
pointer. I have one in my
grinding shop. They do a
great job. The point setters are for 118 degrees. lf you are doing
135 or 90 degrees you need to change the setter to the proper chisel angle . The drill holder and the bushing it
goes in can wear out and
may need replaced . I have replaced mine once
The bushing is a pretty tight press fit . As I said they do a great job. I enjoy your videos very much. Good luck with your mill.
Seems that there, many times, is something to fix to fix somethin'!
Great Video!!
Always relaxing to watch your videos. Thanks for the content. Happy Birthday to your daughter and wish her smiles, laughter and friendship at every turn.
Nice to see you fixing stuff again! The world always seems a little more rational after I watch one of your videos! :-D
I love the music, very restful.
Lots of nice little fixes this week. That press will sure come in handy now that you’ve got it working.
i think a lot of the junk/solids in your hydraulic system may come from the flexible lines and rubber seals in the system. nature of the beast. that's a super nice press. rock on!
Steve it was good seeing some green outside the window and not white. Also I thought you only had two kids not three. lol Your children are blessed to have parents like you two. It seams like if you need to fix something you also have to fix the tools you need to fix the first thing. It is a rabbit hole I know I have been down way too many times and am sure so have many other people. Really do like the music choices and the you do not blast the music compared to the voice levels. Great work .
Gday Steve, it’s bloody awesome to see you back in front of the lathe again, it’s been a while mate, throughly enjoyed watching as always, cheers Matty
Great episode man.
Happy birthday to your daughter, mine also turned 18 this year and it is a funny thing to think about how fast they've grown up
so good to see you back at doing shop work , rather than working on the shop
Mushroom tire plug warning. Sometimes those plug work great. No problems. Other times, apparently depending upon hole location, the steel belts in the tire saw through the head of plug. A friend plugged his tubeless motorcycle tire. The dealer and a new tire was 90 miles away. He had to re-plug the tire 6 times to get the bike to the dealer. At least that is how many mushroom plug heads they found inside the tire when it was dismounted.
Yep. that’s why I’ve never used those on steel belted tires. Work great on non steel belted tires like lawn mowers, atv’s, etc.....
That's the beauty of a 4 jaw chuck - but only skill and experience, which you have plenty of, to get that concentric turning done! That evaporust is brilliant - and it's obviously not harmful to the hands, i've seen Hand tool rescue dip his arms in it enough times!
You need to build an adjustable catch table for that press. You are coming along nicely with your shop.
Nice video, lots of interesting projects 😁
Good work as I can see. You need a set of bearing splitters for the press to simplify taking off bearing.
Happy Saturday Mornin Steve, Grits, and lots of interesting projects! You never know what to expect with Steve but it is always, interesting, instructive and inspiring! I learned about chain hoists, hydraulic presses, flat tire cures, and electric motor bearings today. Way Cool! Look forward to Saturdays all week, thank you for sharing your interesting journey! God Bless
Great to see shop work again, Steve! Not that I didn't enjoy all the shop construction work :-)
yeah, this! And a dollar that next week we’ll see the DoAll Saw? :)
Good to see some machining going on in your shop. Been looking forward to it.
The more that I get to see you use the electric fork lift, the more I realize how nice it would be for a portable work table/lawn mower lift! I love how the shop is coming together.
That lift is a handy thing. I think Steve is going to have to do some mods on it in the future to make it even more useful around the shop. Be nice to see it with adjustable forks. To heck with keeping things stock if they come up short.
Thanks Steve for sharing your adventures in the shop. It's great taking things apart and fixing them up! I'm looking forward to starting some work in my little home shop now that I've got a mill and lathe working in there. Looking forward to next weeks video Steve. Regards from Wales
Happy haircut,
Steve, growing up I worked at a service station, we had a plug gun like that. Also in my military service years our motor pool used those. Worked very well. I enjoy your videos and have picked up a few tips. Thanks.
Those plug guns were around in the 60s. The difference I see in this one is putting the end in the hole before screwing it on the gun. The one we used had tapered plastic tips that allowed the end to be put in the hole while it was on the gun. If I recall, their use was stopped with the use of steel belted tires. Tire manufacturers questioned the safety of plugging a tire. I don't know if it was an actual concern or a way to sell more tires.
@@tiredoldmechanic1791 Those steel belts will just chew that soft Chinese rubber plugs up.
You do nice work Steve, it’s a pleasure to watch a good engineer at work. Very interesting and informative. Keep the videos coming. With regards from Tom in Lancashire England, peace and god bless.👍🛠🏴
Place a new bearing ball in each check valve and give them a rap with a punch and hammer to seat them and then replace with new balls. Will true up the seat. A man that repaired jacks for a living told me about this.
thanks for the pro tip brother
Saturday morning Steve Summers!
I would be tempted to replace the single-sealed back bearing with a double sealed one. The rear bearing can't be greased with that hidden grease nipple so might as well keep it sealed up. Thanks for this comprehensive and interesting look at a few issues around the workshop. It's always a good feeling to repair something so it works properly again.
I'm gonna guess next week is the power saw......always enjoy your videos Steve. Really enjoy getting old things/equipment back in running and working condition!
A bearing separator is a great tool on the press to give you some bite and spread the load out further. Those press plates wouldn't be adequate for Harbor Freight 6 ton.
Covered a lot of ground this week. Great progress all around! And a good week for viewers, too.
I bought a bearing puller at harbor freight years ago working on motorcycles it's two c plates with two bolts that goes behind the bearing and a harmonic balancer looking piece that does the pulling it works the best for these bearings 👍👍
Steve, its good to get back into the shop? aint it? a surprise??? i can hardly wait! take care. poppy's workshop says HI
Steve save all those screws you pull out of your tires incase you want to build a road one day.
The tire plugger is great. I've been using one since the 80's. I also have the small, motorcycle set in a saddlebag.
