/ stevesummersat the quality of some of the older units. - Наука та технологія
The chuck I assumed was AC voltage is actually DC voltage which makes alot more sense. The stamped 110 or 115 volt on the front through me off not being up on these units. I need to investigate it further to see if it is actually bad or if it was just my misunderstanding of the way it works.
Steve if you find it is broken, try dismantle maglock and remove the coil as they are easy to rewind or fix ,I would happily rewind the coils its not hard but only downside is am in Uk .Inside the maglock there is a coil with a iron core if the coil has broken depending on how broken it is you can try repair if just a broken wire.
The chuck works😅. It was a loose wire in a crimp connector.
My background is in physics and electronics, not machine tools. However, I would suggest that you find out exactly what flavor of electricity is going through the wire from the transformer to the mag plate. Transformers generate AC current. I highly doubt that the mag plate and any part on it are having their magnetic field reversed 120 times per second. So, inside either the plate or the transformer there must be at least one rectifier. Even in the 50's, rectifiers were big. A single rectifier could make use of only half of the AC power, and would induce a DC bias that would create all sorts of problems in the transformer. So, there is likely to be at least a 4-rectifier bridge circuit somewhere. There would also have to be a ballast somewhere to supply DC current for the few microseconds while the bridge reverses polarity.
In other words, I would expect that a typical mag plate made before 1970 would have a rather substantial circuit board somewhere in it. Plates made after 1970 would have a smaller circuit board. I suspect that many early circuit boards have broken down and been replaced, hopefully with one of the newer ones.
Again, I am arguing from general knowledge about electronics. Hopefully a better-certified professional can help.
@@SteveSummers Excellent! Glad your diagnostic efforts panned out!
Tell the truth Steve! You called Big Clive, didn't you? I'm glad you figured out what was going on with the chuck. Looking forward to seeing the B&S in action soon!
I know from experience being the sole provider is a challenge but I thought your lovely wife was working outside the home. I wish you all the best as you sort things out.
It's always a pleasure to see someone that know how to pour from a full container without making a mess.
Steve, the drum switch for the mag chuck is to reverse polarity and release the work piece. it also takes DC current to run the mag chuck usually. and in some machines the mag chuck is on its own fuse in the control circuitry cabinet. so you may have to go check that as well.
I have a lovely old B&S model 2 surface grinder. Mechanical drive. About 90 years old. A work of art. Did a test grind on a piece about 6x2x1" and got within a hundred thousands. Lovely surface finish. Incredible.
So glad I found your channel! It’s really comforting to have someone with a sweet, gentle demeanor doing machining, which is primarily people who don’t show their soft side. You and Cora are wonderful to watch!
I’m sorry to hear about your family struggles lately :-/
Steve I just love your videos man. Hate to hear y’all have had troubles but lots of us out here are with you in spirit. I’ve been a woodworker for 20 years now but just getting into machining. I’m inspired by the way you just patiently attack ANYTHING regardless of what it is - I find that most things can be accomplished with that kind of attitude.
I rebuilt a 6x18 Micromaster back in the 80s. They are an excellent machine.
The filter that they sent me, when I ordered parts from B&S, was half the length that I needed. Two of them fit in like one of the long ones would have.
They recommend Endoc c grease in the spindle bearings. I had to buy a 5 gallon pail of it to get the 3 ounces that I needed.
Another great video Steve. Thank you and very much appreciated. Sorry to hear life has been throwing a few curve balls in your direction. You have your priorities correct, in that family has to come first. Hoping things are getting better for you and your family. No beef from me about the frequency of your videos. Quality over quantity, every time.
Thanks, all things considered we are doing great. Everyone gets those up and down times. I definitely don't have room to complain but I can try😊.
May all the situations resolve positively! All the best to the Summers!
My main situation is lack of time😄. It's the same story for everyone .
@@SteveSummers Steve, I am no longer a youngster like you; I don't think I have ever missed one of your videos since you began your channel. With the work you put into shooting and editing these videos and your projects, when I consider the demands of your full-time job and the overarching requirements that you have as a husband and father, I remain Convinced that you have found the secret to 36-hour days an 8-day weeks. 😉I bet everyone here would love to know how you do it. You are doing the right thing by fitting all of this in now when you are young. I thought I would work hard and do all these fun things when I retired... You must be fortunate to get even half of your planned retirement projects done before age starts to sap your strength and endurance.
Steve. I have a Micromaster myself. When I was cleaning and inspecting I found some if not all that the Bijur metering units were not putting out their required flow. To put it in another way, they were clogged or sluggish. These metering units lube all your sliding surfaces. I then immersed them in some lacquer thinner in a small cup then put them in my ultrasonic cleaner. What happened next is that there was a lot of dark and gunky material that was coming out of the units. I had to repeat this process on some of them multiple times. I also fabricated a screw on adapter so as I could blow compressed air through them, and again, I got some junk out of them. I had to rinse and repeat till they were clear. This process worked well for me and I have done the same on some of my other machines. I also went so far as to blow lacguer thinner through all the hard lines that the metering units were connecting to. This produced so much more oiling especially to the X and Y axis. Now, having said what I did, If perhaps you find out that your metering units are not up to par you could just by new metering units from Bijur. Your time verses money is your choice. For me, I found it challenging. Take care.
I worked for a manufacturer several years ago (25 +- 5 years or so). We made small shafts for switches, washer/dryers e.g. We used Brown & Sharpe screw machines. I'm not an experienced machinist by any means. The those machines were old back then, but with proper care, would zip off thousands of parts without a hiccup, requiring only tool sharpening, good oil flow to the tools. Just needed to pay attention. Would hold a tight tolerance.
As a viewer I'm just happy to see what people are doing. Many creators spend much more time editing than would be necessary and it can lead to burnout. Most of us would be fine with raw video whenever you can do it. It's a hobby, not job. I hope your problems resolve themselves but I know life seldom works that way.
Yep, I know the feeling well. There's always something unexpected that gets in the way of moving forward with a project like this. For me it's usually because I come up with a better way of doing something and have to buy more parts or spend more time working on the design (or both), but it's always something.
I hear ya on the issues! It’s going around apparently. Every project has turned into exponential related projects but I am still hammer down making things happen! Holler if ya need anything!
Hey Steve, old electrician throwing in his two cents. Hope you don’t mind. Pull that thing apart and look for a wiring defect. Give it the sniff test, which is a pretty good indication if the potted insulation has been burnt. I wouldn’t be surprised to find that one of the Leads has just broken, I’ve had that before, as electrical equipment repair technician. Sometimes you find a lead has burned through, but the coils aren’t bad. Then hopefully you can just chip out some potting material and expose some fresh wire, and reattach the lead. If you’re lucky. But the only way to know is to look. And I have replaced the coils in some of them. It’s a pain to burn out the old one, and then check wire gage and count the number of turns, but I can’t really say it was difficult. Just messy. Any motor rewind shops in your area?. These are generally much easier than a motor.
thanks for posting Steve always good to see you on Saturday
Steve, The lamp on your surface grinder is a VIMCO brand lamp. It stands for Victory In Manufacturing, and made in Buffalo NY. These are sought after lamps. Very similar lamps were made by Buffalo Morelight company and The Body Electric company. ---Doozer
All a man needs, really, a dog and a fire extinguisher.
(Edit: And at least one working mag chuck)
The woven element looks like water filter used to reduce particulates in well water. Sow rated cable so it was good for it time replacement was well in order given it shape it was in .
Steve,
The table movement is slow for sure. I have the same machine. Mine is a 1966 version.
Before you run the spindle assembly up and down, run the table back and forth or run the upper assembky forward or backward, you need to make sure all the Bijur metering valves are not plugged. Make sure you have oil flow to all end points.
The Bijur metering valves come in five flow amount units. 0-5. The older original valves can be cleaned because you can take them apart. The later ones were crimped and must be replaced. It’s good to see you have the correct oil. You just need 15 gallons!!
The odd thing, my intake oil filter is a fine mesh screen. The return oil system filter is a cone shaped wool yarn design. My filter housings are different as well.
You have a beautifully designed surface grinder. These were the best in the business back in the day.
I recently replaced the spindle bearings. Not a difficult job. I replaced them with NSK precision #7 made in Japan. I paid less than $300 for the set. You can find them for $1,000 from the company that purchased B&S.
When I did the five block test, I had less than .0003” between the blocks. They can be very accurate grinders.
Good luck
Oh, all the manuals are available from vintagemachinery.org
OUTSTANDING - Glad you found the problems with the mag chuck. Onward and upward my friend. Hope the family things get resolved and calm down. Deep breath and keep on truckin'. You've got this.
Cora's just a little sweetheart of a pup....one of those things ya didnt know ya wanted until ya got it--lol
With the manual mag chuck, all it needs is stripping down and cleaning inside, then the pin for the handle needs to be replaced, as that has sheared, hence why it moves ao easly.
Id also pull the newer electric chuck apart too, as it could also be a simple fix.
Another bucket of liquid gold and you are ready to grind. Read where the mag chuck now works. Good deal. 👍
I hope all your family/health/financial/whatever issues resolve quickly and favorably!
Nothing like that secret solvent/degreaser 🙂 as long as it airs out and If you don't mind the smell for a bit it's great for the price.
One of the few times you can say it’s Cheap…..
But Diesel would probably be safer 😊
@@thedodger7030 My garage "Steve" recommended diesel for exactly this reason.
Steve,
A suggestion for dispensing controlled amounts of liquid from a 5 gallon pail...
Lay the pail on its side with the pour spout at the top. If full shim the front edge of the pail with a 2x4. Open the lid or bung. Roll the pail to lower the bung hole until the liquid gently pours into the receiving container. Rolling the pail back, shuts off the flow. I like to do this on a bench top for ergonomics.
Have a rag handy to wipe a drip if you have any mishap. Normally the rag is only a precaution.
Stay safe and we'll see you next week.
I hope that your family is healthy and God be with you. 🙏
Thanks!
Love the secret solvent. Wish there was some way to figure out what it is!
Your secret solvent seems to reek of 85 octane. Cora knows and is on the job. Now that is a good dog.
I love that set. I actually use the small one the most cause I do alot of small electronic stuff. I really like that it has the JIS philips which are slightly different from the normal ones.
Steve, I am a big fan of those Harbor Freight flash lights. As my eyes get older, I use these flashlights more and more in the shop. I had other ones, but I started buying a lot of batteries. These rechargeable lamps solve that. HF came out with an Icon brand version of these, which folds up better, but these Braun lamps works more than fine for me. -----Doozer
Hi Steve. Great vid. Never mind about vid frequency. If family time is needed, that's all that matters. My mantra has always been, "It could be better, but it can be a lot worse too" . Keep your chin up and only go down, kickin and screaming. All the best to you and your family.
The chuck is a DC device. Start the troubleshooting by checking the resistance of the windings of the chuck. According to O.S. Walker, a manufacturer of chuck controls, you are looking for 110ohms of resistance. I suspect that the drum switch had it's contacts welded as it is not designed for switching DC. AS with the spindle cord that was bad, check the chuck cable as well. The small size twist lock connectors have very little space for the wire, check those as well. If you get the expected resistance value and you do not have a short to ground, the chuck is good. Recheck the resistance value, all the way back to the controller, an easy way to find open circuit conditions.
Having the spindle turn, the hydraulics work, you are 90% there. This piece of art is definitely NOT junk.
Happy Saturday Steve, Cora, and Grits. Sorry to hear of your personal problems , life is not always kind But often it is kind. Another great Saturday. Missed you last week. Thanks for taking the time to share the good, bad, and Ugly! God Bless!
I think this is the first video that I have seen you make that did not go as planned and it was good to see. Hope everything starts to get better with the Summers family immediately.
One of the main reasons I visit with you is/are no stones ever get left unturned with your diligent servicing of all your equip and rolling stock. Fixing the manual mag chuck and going ahead on the new machine is worth the effort in my mind. That buy/auction win of the tool blanks really was a good score. Penny's on the dollar well spent. Just imagine the chips you can make with the inch and a quarter tool could make on that great old shaper can make in a short time. Oh well. We are still waiting on the progress on that big old DoAll horizontal band saw. That is one more piece that can either come in from the cold or selling. You have a bunch of time and resorses involved on that one eh. Well Steve. Great post and we all await your next one my friend. Take care eh. From a Canuckian to a Kentuckian (LOL) have a great weekend. You should take some time to relax or play. You most certainly deserve either or both of them eh.
Awesome as Always...Really cool content thankyou
Steve, it might have been to your advantage to make a tool to spin the excess or dirty oil from those filters. They actually make an air powered spinner for inside of air filters, such as on diesel trucks, and the like. This is where I got the idea, but without the air. Probably a piece of all thread in your drill would have been most adequate.
Hi Steve, glad to read in the comments that the chuck is fixed! Hopefully, the transformer has a similar easy repair. As much as I enjoy watching your videos each week, family always comes first. Also, a wise man (or woman) once said "A problem shared is a problem halved". Looking forward to seeing you make some metal dust with the new grinder. Thanks for the video!
Thank you for sharing.👍
I started on a old B&S way back when (60s -70s). It had the best spindle for any grinder made.
Not going to lie...I had my doubts on the iFixit kits. I finally bit the bullet on one, and have been VERY happy with it. VERY well made, the bits are great...I was sold on them.
Vevor 6 x 18 mag chuck $189.95. Mine works great so I bought a second to use as a surface plate I can hold items firmly when inspecting
I hope things go better for you
Sorry to hear and see the problems
Hey, way back when mo max cobalt made me money. Cutting steep taper threads on oil field threads mainly subs. Could pull a blue chip in 4340 heat treated, minimal touch up. Good stuff.
Good morning all from Lincolnshire UK 🇬🇧
thanks Steve
MoMax cobalt, wow! That brings back memories! I was always brought up to believe Brown and Sharpe was top notch kit, I'm sure she'll be fine! Best Wishes from Somerset, England.
Good to see ya Steve and Cora, great following your process.
I hope the things you can change, get better and the things you can't change sort themselves out in the best way, they will no doubt benefit from some patience...
When you feel like your patience is being tested, then you know that you are at least doing something.
All the best.
I don’t believe a B&S could be junk. It might have issues but if you have a very well designed machine any of them can be fixed especially by a guy with your skill set and experience. Surface grinders are simple machines when it comes right down to it. Might need some scraping and turcite but all doable. Maybe a fried spindle will need a specialty shop.
You don't have to use "secret solvent", use Jet A/A1 as your cleaner, available from your local airfield for a similar price and much safer
or indeed Paraffin, which is what Avtur basically is.
@@althalus401 Yes, but oddly no cheaper
Very stylish blue jeans hahhah! 😁
Sometimes rust builds up under the magnetic chuck and the table. People just true the surface time and time again. The thing you can not tell unless you check.🤔🤔😊😊
Hey, back when, I was pouring out of a container and told the boss that I was doing how an old guy showed me to do it, he said an old guy showed me too, referring to me. I have faith this will be a good machine. I bought a Harig myself, little machine 6 x 12. Big enough to grind my stuff. Bigger, take it to work and sneak it in. I will say again, probably really good machine.
Really enjoyed the video
good video steve and elisabeth
great to see that moment of truth when an unknown machine comes back to life after years of just sitting around.
Good morning from Cambridgeshire, UK!
That is a "the gods must be laughing" situation.
Morning all from good old Dorset, UK!
open the Chuck, usually easy to fix
I hope the family is well I understand things come up and one has to take care of them the videos we can wait the family is first
My dad used the same secret solvent working on diesel engines.
I wonder where you can buy it in large quantities. 😉
Took me a sec to figure it out 🤣
Fix the chuck! If it is rectified inside the chuck, It could be the diode assembly. Some Items like the chuck would have a
protective thermal unit to turn the thing off if you left it on, say overnight. The rectifier would have to be inside the chuck assy as you are feeding the chuck 120v ac. Looks like whatever is wrong is a unit that is normally closed but open now. I would suspect the thermal cut off device.
I am sure you'll get that machine running like it was just made
"Secret solvent" in a pan doesn't even make me blink but filling the sure shot with it just makes the hairs on the back of my neck stand up. You can just hear the guitar riff from "shake hands with danger". It shouldn't ignite, I can't imagine any ignition source in there and I doubt a flame could ever travel back up the nozzle even when using air as the propellant but there's just something viscerally wrong with making an explosive mixture in a metal pressure chamber that you intend to hold onto while you're working. If disaster struck and it ever cooked off on the inside that would definitely be one of the worst possible ways to die. If you find yourself creating a literal bomb when you're not intending to create one, you should probably take a step back and reevaluate your life choices.
I would definitely take a look inside the chuck - it may be dirty or one of the replaceable components has gone bad.
I'd suggest that too, it's already broken so it doesn't matter if you break it more. Plus if you're lucky it might be easy to fix, maybe just a broken wire. If the coils are cooked you're out of luck tho
Just a suggestion. If you disassemble the magchuck, on the coil, you may find a thermal fuse. When they get too hot, they burn out and protect the coils. I would bet one has fried out.
Sorry to hear about the mag chuck. That'll be nice of you get it working.
I saw Tom lipton rebuild his barrel switch for his brown and sharp grinder a while back. Seems like there should be a better alternative but I really know nothing about it lol. Either way I liked the video buddy. Always fun pearing into your shop with ya
It’s small but hope it helps, and praying for your family.
Thanks Tom .
Well Murphy has been there. B&S grinder looks to be in pretty good condition. Hopefully you can find a mag chuck soon. Thanks for sharing.
2 mins in for the love of pete i hope he puts the freshly painted chevy outside before testing the grinder!
Someone famous once said "Well, that bites."
Steve is a very smart and resourceful guy. I suspect that he'll MacGyver a magnetic solution.
Good thing you have an eye-ball.
You were right when it rains it pours. Hopefully you will find another mag chuck. Pray the family is good and everything turns out in your favor. Till next time, take care.
Hey Steve, Your new grinder is an exemplar of most of my auction buys. But, mine have been fixable with some applied work. Great get on your HSS stock!
Good morning from Germany ❤
Fulflo FB8. Used to filter oil on oil fired boilers and furnaces. And grinders I guess 🤷 plumbing supply house will have them
The secret solvents do a good job 👍👍
Gasoline. Anybody that doesn't use it is a fool.
Good Morning from Germany.
Good morning from Peterborough U.K.
First thing I'd do on a surface grinder, pull the table and see, if the ways are still good.
Seen so many of them, with toasted/seized/galled ways.
Hi Steve,you had to buy something? Where was Al ? Hahaha.Shes a beauty. Cora is a good girl.Good machines have painted glycol like paint in the reservoirs.Dont forget the pick up screen on the bottom of the pump.Put those oily matts in your wood stove.
Hey Steve, remember that grinding individual blocks is no indication of how flat it is grinding, only how close the surface of the chuck is to the ways. If the ways are like a ploughed field, you can still get perfectly matched blocks. It's easier to mount a known straight edge on the chuck (turned off) and indicate along the top. No chuck needed at all really!
Mineral Spirits. Cora is adorable
Hi. Just in case. I believe that it is a good idea on hydraulic B&S machines to let them idle and warm up before moving the table per the manual
I have been grinding tools for a living for over fifty years and I have never seen anything from Cleveland twist that wasn't first rate stuff ! I have seen a lot of cutting tools from China lately and it is mostly junk. When a customer gives you a tool from China you just do the best you can. But that's another story.
Hmmmm that solvent is a real mystery Haha
I had luck with most of my auctions, got me TOS FN25 mill and Klopp 550 shaper in excellent condition, and i have struck gold with CME FU1E mill.
If you know who was previous owner and what he did, than you can estimate machine condition with more ease.
Most of my machines where in maintenance and tool making departments, not in production.
Never apply power to magnetic chuks withouth mains isolating transformer. Isolating transformer than rectifier and varistor supressor. In that order.
The chucks get coolant in them after a while and start corroding. They're not too hard to rebuild.
Steve keeping these secret solvents to himself. I can't believe it!😁
on the SURFACE it looks good hope you fix or find a mag chuck
Nice machine. I run Okamotos and a Chevalier automatic grinder sometime for days on end.....but I'm sick of being a machinist.🤣
WoW 😲

If the chuck windings are open circuit (the first test I'd do) then my bet is your local motor rewinders would repair it. Bet you could DIY if you could get enamelled wire.
