I have cut and shaped a wind deflector in tinted 5mm thick perspex. I want to put a shallow curve in the perspex along its lenght IE: curved on the vertical plain.
How can this best be acheived?
I don't wanrt to experiment as I don't want to F it up.
I'm thinking oven? or heat gun?
Any tips would be of great help.

Hi lightning,
I occasionally have to bend perspex at work and have found it works best if you can get it under tension in the way you want to form the bend and then apply heat evenly with a gun as you increase the tension...May require starting off with much longer bolts/threaded bar/screws or whatever yu can use.
Apply heat on both sides of the piece or it forms very fine stress cracks, and not to severe 'cos it can quickly 'char' the surface which looks crap.

Hope that made some sense...

Hi steve

I sometimes work at a display company that bends perspex and they use an oven. They make a mould out of mdf and just let it sag over it as it heats up.

I'm sure theres a company near you that could do it, look under "plastics thermoforming" in the yellow pages

Thanks to you both. As the curve was slight I used a heat gun which worked fine.
