Advice needed please - cover for pond filter housing

One or two luthiers who also sell bits and pieces out of the back door still seem to have it available to buy but it seems to have waned in popularity amongst the regular wholesalers - though to be fair, I've been out of the business for quite a few years and am not the best source for up-to-date information. I still prefer real bone, myself.

Not sure they'd be big enough. Are there any which are bigger than

900x600? Not sure anyway whether a paving slab could be cut into the corved shape needed.

Why do all the descriptions say that it's a solid *surface* material rather than a solid material? That suggests to me that it's a surface layer on top of something else - and some of the pictures I've seen appear to bear this out.

Can't see it being popular for pen blanks if it had a different core from the outer skin, I assume the word surface simply applies to the whole of it being a worksurface.

Because that is the full product name the manufacturers assigned to it?

.. lots of technical info here on moulding etc. which should allay your fears..

.. and I think its meant to imply the opposite of what you are assuming as opposed to a tiled or laminated worktop where there is a thin, not very solid surface

Quite so.

From the Product Overview, which is copy-protected, so I can't just paste it here:

"Corian Solid Surface sheet is a solid, non-porous, homogeneous surfacing material, composed of - 1/3 acrylic resin (also known as polymethyl methacrylate or PMMA), and 2/3 natural minerals. "

It says that it is available in 6 mm, 12 mm and 19 mm sheets.

I guess it is possible that a worktop supplier has saved money by using a thinner sheet supported on ply, but I don't think this is usual

That good old DIY standby the angle grinder will make short work of cutting the shape. Could you not use a number of paving slabs and seal any gaps between them until you need access?

But the largest slab I'm aware of is 900x600 - and the cover needs to be at least 960 wide. Also one of the long curves is concave. Not sure how an angle grinder would handle that.

6' fencing gravel boards?

Where did you get the idea that it's copy-protected? It's not:

Well, using Firefox, when downloaded and viewed in Acrobat, I tried to cut and paste, with no effect. Checking document properties, Content Copying shows as "Not Allowed".

Clearly it presents differently to you.

Strange. I was also using Fx and opened the document in qpdfview (Linux Mint). I just tried another pdf viewer and it's the same in that. And, FWIW, the document properties show "no security".

I don't have Windows, but it'd be of interest if someone else using Windows and Acrobat tried to cut'n'paste to see if it was blocked with them too.

I have mint/firefox and I can cut and paste the product pdfs. Using firefox's own pdf viewer at least

Confirmed here (Chrome, W11) that it will not copy out of Chrome directly, nor out of Acrobat.

Mac/Safari, and Mac/Preview cut, copy, and paste works fine. The document is password protected though, so can't be edited (created in Mac InDesign) without a password.

SumatraPDF shows that "copy text permission" is denied, but AIUI obeying such permissions is often disregarded by PDF viewers, and I can copy paste it.

This has been an interesting discussion and I've learned a lot. But I can't somehow see myself using corian for my pond filter cover. If bought new, the cheapest pattern seems to be about £600/M^2 - so a 1500 x 1000 piece would cost me about £900! Someone originally suggested trying to find a scrap piece removed from a re-furbished kitchen - but can anyone honestly imagine someone scrapping a piece that size without any major cutouts?
