DIY Magnetic Chuck

Make a magnetic chuck from an old microwave transformer.

Then take a look at the vise and belt sander he makes , you can get plans from him also .

An interesting project but I don't like their pricing system.

As I understand it and I may have mis-read it, you need commit to subscribing $10+ a month to get the plans. No mention of how long for.

I wonder has anyone on the Forum tried to build something similar?

The microwave transformers have been used in the past to make a spot welder. Details published in a previous edition of MEW and lots of others on the internet (for free).

The idea of a magnetic vice for holding thin jobs on the mill appeals to me. Just don't like having magnets around my tools in case they become magnets themselves and pick up swarf.

Thats another use for the transformer from a microwave .- a demagnetizer .

Super useful if you do a lot of flat stuff

Older ones show up on e**y regularly and go for decent money because there is always interest

Why are people so coy about typing eBay?

Small magnetic chucks on MSC offers are cheap so not worth the bother to make one.

Just looking on the junk shelf the other day, at least 4 microwave transformers, and one stripped to make a spot welder.

To build one, the mechanics are simple, the only thing needing any great thought is the power supply.

Starting at £100 from MSC I gotta think that for the average hobbyist its worth a go making one rather than buying

I'v got the demagnetizer, it uses a coil from a microwave oven, and the transformer control from an old electric blanket (3 heat)

That looks like a bit of very sophisticated gear !!!! I assume that the micrometer is used for accurately setting the dial on the transformer.

How does it work ?
