Lets fix up and restore a magnetic chuck
The mechanism was completely seized and needed attention
This isn't a repaint restoration, or a pristine perfect restoration. I just want to get this functional and use it.
The chuck has been sitting on the floor of my shed for 6 months due to it not working. It was still wet inside when I opened it up. I would say the bacteria / corrosion has been happening for 10+ years
The pin material was 1214 steel supplied by Tyne Valley Metals. They have a variety of engineering metals including 4140, bearing bronze, D2 tool steel and more.

I've bought and sold a tonne of mag chucks recently, people advertise them as "it's just lost its magnatism" but in reality it's just something worn or seized and it's usually an easy fix, great video 👍

I just rebuilt one too. You left a lot of crud inside, you really need to remove the magnet and clean the surface that contacts the top. I did mine and applied a film of synth grease. The trick is to remove the magnet when it's in the "off" position. Slide the magnet off the side. If you can, spin at an angle relative to the base. Getting it back on is a bit more tricky. Put a piece of HDPE or something similar that is about 1/ -1/4" thick ( I used a small cutting board from the dollar store) on the top, then put the magnet on top of that. This provides enough separation so you can still align them. Once it's where you want it, carefully slide the plastic separator out. The reason so many of these get so dirty internally is they are mostly used on surface grinders that use flood cooling. As we all know, coolant can and does get pretty funky with all sorts of nastys growing it it. Mine was a mess inside too.

Cool I might give that a go. I was worried about finger crushing lol. and yeah it's a wet grinder, the tank was festy too. I mainly wanted to get this magnet working for an experiment. It will probably end up sitting on the floor for a few years when I'm done lol

@@TomMakeHere Do be careful, these buggers are strong and will bite. Probably not crush but they are strong enough to "leave a mark". Yours looks to be a bit easier than mine was. My case was two pieces, not three. There was a top section much like yours but my bottom section was one piece so you had to stick the magnet to the top and get everything lined up perfectly so you could get it to slide into the base. I use mine to hold small plasma cut outs while deburring them. I use a piece of 22g sheet metal as a protector sheet on the face of the mag chuck so the wire cup wheel doesn't mar the surface. The cut pieces stick with no problem. Great little addition to the shop. I've used it way more than I thought I would.

Hi, thank you for explaining how these work. I’m hoping to build my own. One question, please. Does the top plate have the same magnet arrangement that you see on the bottom? And when you turn the handle, they offset thereby turning off the magnetic force? Thanks. Love the video.

1:15 don't strike magnets with iron. it can weaken them. maybe a nylon headed hammer? deadblow? nice job on the threaded pin! I just watched a video on how magnetic chucks are made - they said they fill them with grease and graphite before they close them up.

So I sat down with my breakfast and this was the first video I pulled up to watch, looks like I made the right choice. By chance did you put down some graphite grease or create a seal between the bottom plate and the housing? Looks like it works well though good job, mag chucks are great tools.

Hey Tommy got a question for you. I want to use the mag chuck to surface my steel to make knifes but I only need the width to be 3”x18” instead of 6”x18” , with your knowledge of what’s inside is it possible to cut the guts to that width safely? I’ve looked everywhere to find a narrow mag chuck. Anyway let me know what you think. Thanks
@TomMakeHere
@TomMakeHere 3 жыл бұрын
Hmm you would need to rebuild the housing as one side would be open which wouldn't be ideal. The magnets are crazy strong and you would want to be very careful trying to pull things apart. Out of interest, does it matter if it is extra wide? The knife would just take up half of the chuck
@stevegarland7075
@stevegarland7075 3 жыл бұрын
Yeah I guess it would be too dangerous. I wanted to mount it on a 2x72 belt grinder and 6” wide is just to wide for that application. The knife maker’s are building there own but I don’t have a mill to cut grooves to hold these magnets and they don’t have the off and on switch either. I saw a set up at the Rockller web site (wood working) they have a handheld lockable magnet. Anyway I’ll change course but thanks for the reply, and keep up the good work!

I cannot find this information wherever I'm looking and it may be stupidly simple but I need to ask- the magnetic side is what holds the material you're currently working on but how is the chuk itself mounted to surface? By screwing it onto base surface or is it something like engaging magnet works both ways?
@TomMakeHere
@TomMakeHere 5 ай бұрын
The table is normally surface ground by the machine. The mag chuck then bolts on with 2 hold down clamps. The magnets are on the top surface to secure the workpiece and they only 'conduct' the magnetism to the workpiece when everything is aligned with the switch

Actually... maybe you should consider pulling the mag pack off the top plate. Mine has 2 stainless strips that were worn down and hence wouldnt allow the mag pack to move freely. I cut new strips of brass of the same thickness and greased the strips with EP grease. If youd like pictures let me know. Mine was a kanetsu mag chuck. Gluck

I'm saving to get myself the crappy Chineseium hazard fraught lathe and milling machine. I know it's not the best, but we've all got to start somewhere. My dream is to have a full workshop. Still have so much to get. Looking forward to it though. It'll be gawd damn lovely to not have to pop a hernia for every project from using hand tools. Thanks for the video. It's really inspiring to see an Australian accomplishing some cool metalworking. We don't seem to have a huge market of second hand machines like the US. I don't have $20,000 - $50,000 to blow on a semi working machine. Hoping that China puts out an entry level surface grinder and shaper too.
