The one on the Thorens is perspex. Not sure glass is a great idea - heavy and prone to breaking.

I know Peter.  I was just wondering if Martin was serious!

This is an option if you want to keep the original lid:

You really need skills to get a perfect result! I don't think I could do that unless I have seen someone doing it!

Thinking about the original lid and how it is supported, I can't help thinking how much
will this lid sag in 20 years ?

Martin

In 20 years time? It doesn't!

Yep Glass would be nice, but too heavy for the hinges for sure. I checked something else also, the weight of the new cover is the same as the weight of the old one.

Looks like there has been quite a lot of thought gone into it.

After much deliberation I have adjusted it to be parallel to the deck also. It does look better this way.

In 20 years I would hope not to be here to care.;)

On a serious note, the material used looks different than normal perspex, it doesn't bend much at all.

I would have thought that perspex would have bent with the weight but this seems to be very rigid, especially considering how it is mounted. They did say it was a special material. Is there such a thing as reinforced perspex?

Much better now!!

Perspex is a trade name, and is an acrylic (PMMA) plastic, Polycarbonate is another type (trade name Lexan), PMMA is used for aquariums, windows, picture framing, among a lot of other uses. Polycarbonate is easier to form and is  not as brittle as PMMA, is used for complicated forms, but is not as scratch resistant as PMMA, therefore an anti scratch coating is used where necessary. Polycarbonate is stronger with higher impact resistance, and is normally more expensive,

The cover here is thicker than the original and this gives it the same weight. Acrylic or Polycarbonate, could be both, but I think the Polycarbonate will sack easier with time. Both types should have a scratch resistant coating if used as cover.
