I'm trying to put fake neon on my marquee. This is actually EL wire placed in polyethylene tubing (milk white tube), which is then placed in clear tubing (3/8" outer diameter). The bend radius of the 3/8" tubing requires that the neon will be set off of marquee about an inch. To keep the lettering on the path that I want, I'll need some stand offs to hold the neon in place. So I'm looking for some clear (probably polycarbonate) tubing that I can cut to length. I prefer tubing so I don't have to drill a hole through it. I thnk I want tubing so I can run fishing line through to hold the neon. Or I can use a rod if needed and drill a hole through the side.
Hmm, come to think of it, want tubing. Then I can run a small bolt through the center to hold it to the marquee.
I can find tubing on McMaster but it only comes in long lengths. I would guess the shipping cost is too high for that.
