Dished CDs?
Dished CDs?Has anyone ever tried to make a CD slightly dish shaped?
I have a little wind powered project on the drawing board, with a prototype to be tested this weekend, but it would look better if I can dish a couple of CDs! Obviously it'll involve heat, but.... Pics if this one works! I'd like to live as a poor man with lots of money.

Re: Dished CDs?OOHH!!! That sounds interesting! I shall have a think.
Ma Larkin Re: Dished CDs?I know you can soften perspex in those little bench top ovens, I have seen it done with perspex rods.
I would try to find a metal or maybe even a pirex bowl/dish of the correct dimensions place it upside down with the cd on top and then try gradually heating the the whole lot. DONT PUT CD'S IN THE MICROWAVE THOUGH No honestly dont. [center]Relax, I could have been a twin.[/center]
Re: Dished CDs?hi mallard,
i have just done a couple of tests and found that heating with a heat gun is to quick and the disk becomes brittle, a hair dryer does not get hot enough to make it mouldable. also because a cd/dvd is basicly 3 layers it is difficult to get the heat to all layer at the same time. i have one slowly cooking in the oven now i will let you know what happens very soon Get free Electronics easy

- Pablo Picasso Re: Dished CDs?How about making an improvised oven? Thinking out loud here but maybe a disposable barbecue with the mesh removed and raised up on bricks. Then something to create wind shields on all sides and a top. This way it can be done outdoors and if the whole lot catches fire then you get warm while thinking of plan B.

Re: Dished CDs?had the cd sitting in the hobby oven for about 10 minutes @200 deg c i could see the disk flexing so i took it out to see how it bends. again very brittle and separates into its different layers. im out of ideas now.

Re: Dished CDs?I tried boiling one once, that doesn't work.
Ilona Re: Dished CDs?Found this - did the oven need to be hotter?
This one says a bit lower temp Don't know as I've never tried to heat them myself. ¸.•´¸.•*´¨) ¸.•*¨)✰

Don't get your knickers in a knot..it solves nothing ~ just makes you walk funny Re: Dished CDs?To bend some plastics for model making you tape the item over a former then put it in very hot water for a few minutes. I know you would not be able to bend the cd over a dish shape in one go but maybe bit by bit?
Re: Dished CDs?What about taping or even better tying one over an upside down pyrex bowl and leaving it in the garden over the summer?

Re: Dished CDs?Just tried heating some in the oven at gas 1, placed them over a muffin tin, but when I put pressure on them they just fell apart!
This is the project, a wind operated bird scarer, but my aerodynamics need a rethink as it blows backwards and forwards! I'd like to live as a poor man with lots of money.

Re: Dished CDs?Mallard,
Could you put them at an angle? say 45 degrees. That might work.After all aeroplane propellers are angled on the shaft. Dom Ali Woks My World
