I made some impromptu flip ups for the K and my CX
using a hot air gun ( and my welding gloves !!) with varying results
I overheated the CX one and got a white smudge which wont polish out
as its all the way through the perspex
Luckily it wasnt in an area to affect vision.
They both work in terms of stopping me getting
a face full of wind and the accompanying noise which gets wearing on long rides.
Crude but effective is probably the best description.
I found getting the perspex to its malleable/workable point but not going past it
and getting the white smudging the tricky bit.
this was with much smaller areas than anything screen sized.
If I fancied trying my arm at something screen sized I think
Id make templates from paper or card and cut the perspex to shape
If I got that far without messing up I'd then try shaping it by hand and trying to keep
bends as simple as possible.
I reckon its possible to make
something if you're prepared to experiment
BTW I call it perspex'' but I was told there are various kinds of clear sheet
and I have no idea what it was, as I found it lying about and appropriated it
