DIY Magnetic Trimming Chuck

Recommended Posts

I am missing something. Why do you have to build the block, attach the magnets, etc. Why cannot you just use the magnet blocks like on the photo below? They are $0.99 a piece.

Where did you get these magnets?

 

 

Harbor Freight store, but they work only if you have a steel wheel. Otherwise follow John255 instructions.

To all members who are thinking of building a Magnetic Trimmer,

 

My attempts to build simple extensions for trimming tall pots were complicated.

 

Another approach I use successfully is to throw a double-ended trimming chuck and bisque

 

it then center it on the mag-trim. (See photo) Dimensions are not critical.

 

I use a bulls-eye level to level the pot in the chuck. (This assumes your wheel is level.)

 

You could also buy a set of extensions from Bailey for about $16 and screw then to the mag-trim blocks.

Good luck with your Mag-trim, and let us know how it goes.

John I received my quiche pan and then had to wait on the magnets, I haven't got started on this project yet I have another one that I'm trying to finish first. I always have a lot of projects to do, the only way I can stay organized is to finish one before I start another. Denice

I'm wondering how many people built a Mag-Trim and are too shy to post how it is working?

Can potters be bashful about showing their work???

I use mine just about every day and it's holding up well.

Regards,

When i was looking for the $0.99 magents, I noticed the sidebar saying that Harbor Freight is also a source for the neodymium magnets as well, 10 for $2.99:

The Harbor Freight magnets are a little larger, 5/16" diameter by 1/8" thick.  Unit price though they are over $0.03 more per unit, but you don't have to buy 30.  Unfortunately, they are packaged 10 to a package, so you would need two packs, but save $2.01 and still have spares.

John,

Magnet info like this is very attractive.

No matter which magnets you buy you'll be stuck with them.

People who love magnets should stick together.

I love this and will be building one soon. I but I am gonna cut up an old acrylic cutting board to make the blocks instead of using wood. seems like it will work just as well and moisture will never be an issue, not that it would be much of one by the trimming stage anyway.

Nigich22,

I can't see why the cutting board would not work if it's thick enough.

I have one set of blocks 3/4" thick and another set slightly thinner than 1/2".

I've used worn out acrylic cutting boards to make dies for extrusion, and they seem to work better than metal.

Good luck with your project.
