Corian

Note: this is a trademark of Du Pont, the official website for this material is here: corian.com.

Material properties:
Density kg/m3 1730 to 1760
Hardness (surface) 2 to 3 Mohs
Note: These properties should be used for indication only as material properties vary from sample to sample.

So why use it? Well, the range of colours is fabulous and if you select the colour carefully can look like ceramic - so great for making items for dolls houses.

These are some small 50mm square samples that are 12.5mm thick. The first thing I did was sand a surface of each piece, apply a thin layer of superglue ensuring it covered the whole surface and then clamped the two pieces together and left then for 24 hours.


This shows the finished machined part, an idea for a flywheel.

I turned this in a normal metal lathe using tools I would normally use for machining steel.

I turned this at 1000rpm and was careful to take small cuts.

I finished the surface with some very fine wet and dry paper and then finally finished with very fine wire wool.

To keep the temperature down and get a great finish I used NeatCut - a cutting fluid that is sold by Warco and is a fine mineral oil.

I washed the oil off using some soap.


The finish is not bad. I need to practise glueing these together as you can still see the join, I note that some say the joint is invisible if you use superglue...well mine′s not.

Where do you get Corian - well, samples tend to be free, but if you need more then best to find a friendly kitchen fitter as this is mostly used for worktops.
