QUAD ESL 57 A little work on the loudspeaker

I also replace the neon bulbs, but lately I've switched to LED's. Here's my prototype. Those things should outlive me.

I do not have better glue for the process than a bicycle inner tube repairer.
I am a bit worried if it is necessary to 'pre-tension' the dustcover as the one I've been supplied is very rumpled. Should I only straighten the creases out with cellotape on the table and the hair dryer will do the rest?
 
The dust cover material that I use is:

Treble panels: Mylar 6um or thinner, and requires a bit more heat than a hair dryer to shrink

Bass panels: A heat shrink saran material that a hair dryer shrinks nicely.


I'm not sure what materials you have though, so I can't really advise.

The material's 'approved' because I sourced both from One Thing Audio.
The treble material and bass material differs for the touch. The treble dustcover seems more 'brittle' and 'noisy' (?).
Indeed, the materials shrink differently as you mentioned. I had hard time shrinking the treble-material on my testing dummy-frame with the hair-dryer, but it shrunk slowly.

My experiences so far: the TIP-TOP bicycle inner tube-repairer glue isn't the best choice for this type of film. It seemed nice for the bass panel's saran (?), as it 'melted' the foil and gave an excellent hold on my test-frame. But in this case, I can tear the film off with almost no effort. It's there however, see the pics. As this is my first try, I am sure that I will puncture the dustcover when I'm going to try to cellotape it together ...I thing I need a better and less fussy dustcover glueing technique... Should I source some double sided tape?
 
Despite the dismay caused by the tube glue first, I decided to stay with it as it looked OK after some days of drying.
Looks like I successfully managed to cellotape the treble panel together.
