Build of a permanent magnetic chuck / base / vise. Part II

[@ego73]

Can't wait for Part 2! I applaud you, Michel.

[@Michel-Uphoff]

I will publish it soon

[@jamesb.9732]

I certainly admire your dedication to completing repetitive tasks and your sense of humor about it!

[@โนรีคอกเบิร์น]

Well done. I have thought and pondered this for decades but never tried it because no big machines. Now I have a bigger urge tobbuy a mill or surface grinder. Obviously thumb up & subscribed.

[@heinrichhemker8123]

Excellent in every respect!!

[@Michel-Uphoff]

Wow, thank you!

[@LordOfTamarac]

Super exciting!

[@kioliex]

What a great project. Thanks for making all the test and sharing it. This is a really nice project...

[@KravchenkoAudioPerth]

Second last Goldberg Variation! Nice. Good work on the chuck. Two camps one on either end to shift the magnets? I will watch and see. Mark

[@Michel-Uphoff]

Hi Mark. No clamps, it will be a scotch yoke.

[@Sigmatechnica]

nice project. think i might have based the design arround dowel pins instead of having to make all those cylinders! :D

[@Michel-Uphoff]

It builds character ;-)

Is the layer of steel rods between the magnet layer and the item to be held by the chuck? Great video!! Tom

[@Michel-Uphoff]

Yes it is. Thanks!

[@stevewilliams2498]

Michel, On your video replacing the plain bearings on a Proxton apron with ball bearings, it looked like you machined 19mm diameter all the way through. I thought it would be only 5mm deep each side ? If you can remember could you please clarify for me.

[@Michel-Uphoff]

No, not all the way through. I drilled two holes of 5 mm deep and two of 5 mm plus the existing depth of I thought 3 mm, you have to check that extra depth yourself because I don't remember.

Estimado señor Michel fantástico trabajo, estoy deseando empezar a construir una mesa como la suya, ¿podría decirme dónde compro el teflón autoadhesivo? Muchas gracias

[@Michel-Uphoff]

You could give this link a try: armastore.eu/self-adhesive-teflon-sheet-a4-x-0-25 But remember, I didn't use the teflon after all. See the video.

[@karlvella7627]

Hi michel, Well done for the video. It was very interesting. What is the plates thickness for each layer? The magnet plate, you made a pocket or you went right through? What is the measurement width space between each magnet? Thanks alot Karl

[@Michel-Uphoff]

I assume you mean the final plates for the magnetic vice. All three plates are drilled through. On kzbin.info/www/bejne/poillJ6blquimKMsi=tJ_7dCTbx89UdL20&t=389 you can see the dimensions. ( center to center distance 8 mm, diameter 6 mm, 2mm gap)

[@karlvella7627]

@Michel-Uphoff thanks for the info. I am assuming that each plate is 12 mm thickness

[@Michel-Uphoff]

@@karlvella7627 10 mm. Magnets used: N52 ø6*10 mm. Maximum pulling force a piece 1.6 Kg, so a total maximum 270 kg

[@charliemopps4926]

I also have a magnetic bottom

[@bobweiram6321]

Shouldn't this video be part II and the last video part I?

[@Michel-Uphoff]

Yes. Corrected. Thanks!

[@alpha-hv9ck]

😮❤🥰👍👍👍

[@jeyseychelles1370]

The draper stud lock would had been permanent bond

[@Michel-Uphoff]

Sorry, don't understand it. What's a draper stud lock?

[@tek9102]

What size and type magnets are you using?

[@Michel-Uphoff]

Neodymium N52 ø6*10mm

[@joebabb504]

Sure wish you had talked through the principle before jumping in to build.

[@Michel-Uphoff]

Have you seen the first part, prototyping? If so, which principles would you like to see better explained?

[@joebabb504]

@@Michel-Uphoff Sorry. I thought part 1 would explain. What was the explanation called prototyping? I've played with the concept of turning mag fields on and off so I'm very interested in what you've done. I just found it, but seems it is called part 1 also.

[@Michel-Uphoff]

Yes, sorry. Messed up the titles somehow. Corrected that. In fact, I don't turn magnetic fields on and off. That is not possible with a permanent magnet. But I do send the field lines through a movable iron medium to the location where I want them.

[@joebabb504]

@@Michel-Uphoff thanks. I realize we are not turning the magnets off. It is a convenient way to describe the action but you are more correct. I really appreciate what you have done and plan some more experiments of my own.
