Perspex Trimming/Fitting advice Please!
Hi All,
I'm planning to fit a hard-top to one of my projects and have starting thinking about side/rear screens.
Ideally I'd like to use something like perspex unless anyone can recommend something else?
As far as perspex goes what is the best way to drill/fix it?
I have access to a band-saw and tape so cutting shouldn't (?!) be too much of a problem!
As usual all help much appreciated.
Cheers
Martin

Hi
Perspex is quite a rigid and brittle material, a better choice would be lexan.

Thanks Mick,
How does that compare cost-wise and can anyone recommend a supplier?
Cheers

I'm going to order some from Ebay, they sell it iin different thickness and sizes.
As said above, this is beter than perspex and safer
Ebay for Lexan

Yes - Lexan is better than perspex. I got some of mine from the local glazing company - if the size you need can fit into their offcusts they should
let you have it cheap. Another time I got some from here online.
I originally had ali sidescreens with Lexan windows on them - just drilled through and fixed with small dome headed bolts and nylocs. If you are
planning to fix it to a hard top you might get away with just adhesive; alternatively silicon sealant and rivets/bolts as above.

I used polycarbonate sheeting. Worked well. You need to drill / cut fairly slowly or it'll melt and gum up the drill bit / blade.

Perspex = Acrylic (brittle)
Lexan = Polycarbonate (indistuctable)
MAKE SURE YOU THE UV COATED VERSION
or it will turn yellow in sunlight

Its called MARGUARD and has green righting on it if they dont have that use the exell
Lexan Exell D sheet is a transparent polycarbonate with proprietary UV protection, offering excellent weathering resistance, impact resistance and
formability for skylights, covered walkways, roof lights, roof domes and barrel vaults. Lexan Exell D can safely be used outside and will not yellow
from exposure to UV light.
Lexan Exell D sheet is also ideal for machine guards, boat and car windows, and other glazing applications

I used 6mm perspex for the side and rear windows of a mini i restored and turned into a track day car and i cut it with a sabre saw. Its ok as long
as you have fine teeth on the blade, and take it slowly. Its tough as well, when you go for the thicker models, but poly would probably be better. I
would bond it with black PU or black mastic, then rivet into place depending on the project and if you can hide the mastic bonding.
Kindest Regards,
Richard.

Hi
Both lexan and perspex are thermoplastic, ie if you heat them they will bend and the bend will set on cooling. Lexan will bend in one plane cold more
so than perspex, which as I said earlier , is brittle. Vacuum forming is also possible with both.
