Magnetic Indicator Base how it works and the 2 most common fixes

[@nickbell3546]

4:36 the magnet grabbing everything around it was hilarious 😅thank you for the video!

[@flatlander523]

Very cool. Learned how these work so I think I will 3D print me one to use in my woodshop.

Man i had forgotten how bad our slicers were back in the day. Always nice remembering how far weve come. Wonder if ive got any old copies lying around to see what i can get them to even do... Thanks for showing this to everyone. :)

[@shopandmath]

The slicers have come along way unfortunately I’m still using on that particular machine the same slicer from four years ago on the new K-1. I’m using the new software and it’s pretty amazing. Thanks for commenting and thank you for taking the time to comment. It is much appreciated.

Thanks, that was very useful. The device, after an explanation, is so simple, but so useful.

[@shoaibmd2509]

Nice video. I'm facing problem with my v blocks after i opened and cleaned them. The magnetic force used to be strong but now it's very less after I assembled them back. Do you have any idea what could have gone wrong?

[@shopandmath]

it’s possible the issue that you’re facing is that there is no magnet on the inside It could’ve been a magnetic core once you’ve pulled the magnetic core out you demagnetized it Check to see if the core is made from magnetic material or a chunk of steel that was magnetized Unfortunately, if it’s a magnetized core it’s not worth repairing sorry Ray

[@andrebega1867]

I like the video, dude. Thanks. Regarding the magic inside the box, the different materials, and so on... it would be nice if you included a schematic diagram showing the materials, the N and S poles, and magnetic lines. Once again thank you

[@shopandmath]

Thank you for your reply and nice comments I have made a few other videos on magnetism. I may have included them in the other videos, but I don’t remember which one if not the next one I make, I will include a schematic. Ray

[@paulpickford4074]

Useful video, thanks. When my base arrived from China it was stuck and wouldn't turn. Now I know :)

[@shopandmath]

If your bass is stuck. The first thing, check to see if there is a washer underneath the large stud that you bought your indicator too It could be missing and might be screwed into the actual magnet Or it is poorly machine, and the stud portion is too long and it’s stopping the magnet from turning so take that out first If that does not free up the magnet Look inside the hole and see if it is a magnet or a steel slug If it is a steel slug, don’t do anything because there’s nothing you can do If you remove the steel slug, you will demagnetize it, and it will not work, even if you can rotate the magnet Try this and let me know if it works Ray

[@caseykittel]

at 9:00 minutes, is the back of the case aluminum or steel? great video! love the new handle design!

[@shopandmath]

I’m not sure about the ones in the video I would have to go on track but most commonly they are either fully cast along the back or it’s a piece of tin/aluminum The shim in behind the magnet prevents the magnetic poles from grounding out I hope this helps Ray I just finished another video where I repair a magnetic base and install a magnifying light on it I don’t know if I’m gonna post it on this channel shopandmath or on my new channel raysfix

[@RobB_VK6ES]

A better fix for the stripped thread is to bolt down a NON MAGNETIC plate to the top of the base. The plate is the same size as the mag base and about 10mm thick. Use a screw in each corner. Stainless steel works well. You will notice a significant improvement in stem rigidity using this method plus there are no longer any aluminium threads to strip out.

[@shopandmath]

That’s a really good suggestion This is why commenting and reading the comments is so important it helps get other peoples perspective Thank you for sharing and also thank you for taking the time to share Ray

[@f.hababorbitz]

There is a 3rd item to be fixed on real low end magnetic bases. They do such a poor job of grinding the magnetic face surface flat, as well the partial V-block will have faces that are not in a planes that will meet in a straight line relative to the base face, so the indicator rocks on the mounting surface it is used on. I have a few of these. It looks like they did a hand grind at a belt sander. There are some permanent magnet things that should never be opened. Stepper motors, and DC servo motors, will loose much of their magnetic strength if the rotor is removed. The manufacture of these have tooling called 'keepers' that keep the magnetic flux lines flowing through some highly permeable steel during assembly, and disassembly. I know this is not pertinent to this video, but this should be known to machinists/mechanics/engineers/technicians that like to fix things. I've never taken one of these apart. Interesting to see how they work. Thanks.

[@brictophussein2167]

Great video, one question, does a magnet switch attracts another magnet when its off?

[@shopandmath]

The magnet itself does not ever turn off All it does is rotate the magnet, so that polarity is broken That is why there’s two pieces of non-magnetic material at the top and at the bottom of the V I hope that answers your question if it doesn’t, please feel free to rephrase Thank you for the nice comment and thank you for taking the time to comment. It’s much appreciated. Ray

[@Miguelito63No1]

very good video, I need help, I have a BROWN & SHARPE MAG.BASE and is to week, even a baby can pull it when on, there is a way to fix it?? thanks

[@shopandmath]

I could only think of three things that could be the problem Number one there’s something mechanical inside that is not allowing the magnet to turn on all of the way Number two there’s a piece of metal that’s jumping the polls And diluting the strength of the magnet Number three this is a good quality magnetic base and the internal magnet should actually be a magnet not a magnetized blank Magnetize blanks lose their power after a period of time and can also be completely demagnetized in some cases by simply removing the magnetic core If it is a magnetize blank it can be re-flashed but it’s not worth doing replace the base I hope this helps Ray

[@miguelatorres7695]

math thanks, I'm going to take it apart in order to see what is going on,,thanks

[@shopandmath]

@@miguelatorres7695 Don’t forget to check to make sure that it’s an actual magnet inside before you take it apart Because if it’s a magnetic slug on the inside you could demagnetize a slug just by removing it Good luck Ray

[@logwilky208]

My v-block is extremely weak compared to our newer ones. Magnets only lose about one percent every hundred years, so what could be the problem?

[@raysfix]

First question is it a real magnet inside or is it a magnetized iron core A magnetized iron core could lose its Magnetic strength Under certain circumstances If it’s a real magnet it’s most likely be in ground out somehow that does not allow the magnetic flux to travel from one pole to the next Inspect the outer casing for damage if you drop the unit and it’s possible that it has broken and it is also possible that it became unglued Has this been exposed to excessive temperatures if you shake it doesn’t rattle When you turn the magnet on and off is there an excessive play in the switch or when you turn it on part of the way does it slam the rest of the way on or does a train turn itself off Or is it hard to turn How’s the block ever been underwater or under coolant If it’s yester any of these questions you should probably take it apart and see if there’s any rust or foreign objects or broken pieces inside They may be hard to find because they stick together Keep in mind if The magnet is an iron core by removing the magnetic core you made demagnetize a magnet I hope this helps Ray

Hi Buddy, I just today bought my 1st mag holder and am dissatisfied because it can barely carry itself 😕. Can I do something about that, can I somehow amplify the mag force? -Without having fancy tools like 3D or a mill? Don’t get me wrong- I’d love to have them but money’s always short, You know that song...

[@raysfix]

Make absolutely sure before you take it apart that’s a magnetic core not a magnetized piece of steel The only way to increase the magnitude is if it was assembled incorrectly and somehow the magnet is shorting out but that’s highly unlikely it is possible that there’s a piece of steel jumping across the negative and positive Is there any grinding when you turn the magnet on and off? I could indicate that there’s something inside

Sorry, I don’t know what you’re referring to

[@GTRliffe]

i don’t understand the big deal with running powerful fans to the 3d printer nozzle when you can have one large pc fan in a box extracting the heat from the printer head with a hose you can use a quiet 10cm pc fan housed in a way there a hose size port-from there, plug in a flexible plastic hose too printer head-you can pull 10x the heat almost silently! you can place the fan box ten meters away!

[@shopandmath]

there’s nothing wrong with running a fan to extract heat or fumes where the problem comes in for everything that you extract. You’re also adding something and depending on the time of year and where you are on the planet, you could be introducing moisture or extreme cold air. currently, my printer is showing its age I have stopped using everything except for PLA. The reason behind that is, I only do constructive and experimental parts with doing this. I am rather lucky because I can use old PLA and low quality PLA, and still produce good enough quality parts for what I need them for, I don’t do any resell so I can design parts or change the design of parts to suit the end result i’m also currently looking for a machine with a larger footprint to be able to create larger parts

Removing the magnets not a problem

[@marianodiaz461]

Absolutely not , you should never remove the magnet from its housing , that stand will lose 80% of its magnetism within a few days, if you want to remove the magnet you should fitted inside a iron housing of the same diameter than the one you r3move the magnet from...

[@shopandmath]

Removing a magnet from its housing will not demagnetize it With that said if you remove an iron core that has been magnetized it is possible to demagnetize the iron core If you watch the second video I demonstrate how do I identify the difference between an iron core and the magnetic core

[@marianodiaz461]

Seen it all the time , with all the ones , that I have seen that being done , even top brands like Eclipse and Mitutoyo
