Does anyone know a company that could make me small quantities of a double walled tube? The first (inner) tube to be 1.5-2mm wall, clear resin with a single layer of 80gsm woven glass fibre (preferably as close to the inside of tube as possible), the outer tube to be “normal” carbon fibre with standard 1.5mm wall and the outer diameter to be 25mm.
Odd request I know...but then I did say I was the mad scientist...

I understand what you’re saying about the thickness of the CF layer, but counterintuitively it needs that thickness so that the effect of the translucent black pigment is maximised when the design is infilled. With only 0.2mm of depth, with the lights turned off you’d be able to see the white tube through the cutaway. It needs to look like “magic”; not like bits of white plastic with LEDs behind them...it needs to be a coloured design that appears out of nowhere...
...and now I’m just wondering if I just typed total rubbish...just because the CF layer is only 0.2mm, doesn’t mean the design has to be that shallow...hold the phone, Batman, this may change things...thicker walled (4mm?) GRP tube, wrapped in CF for finish, I etch the design through the CF and into, but not through the GRP, meaning I’ve still got a continuous “tube” of 2mm thickness “underneath” but still a good 2mm depth of design to take a translucent black infill resin. Strength AND aesthetics, problem solved!
OMG that would work I’m sure...as long as 2mm of GRP will give me the backlit screen effect I need. Easy Composites people...do you sell a 25mm OD, 4mm wall unpigmented GRP tube? How easy is it to wrap such a tube in a couple of layers of CF and achieve a finish as good as the commercially available high gloss, woven finish CF tubes?
Oekmont, my apologies for being dumb...just hope I can source a material as described now!
