With what do you secure LED wires to your model?

Post by brt » Wed Aug 03, 2016 3:26 pm

So far I have only lit a d-7. I glued the LED in place and let the wires lay where they were. I am working on the 1/537 refit and trying the Raytheon effect. So far epoxy as well as lepages' ultra gel super glue have failed to hold the led/wire in place. What do I need to use hold the LED and wiring in place to the inside hull? Thanks.

You can use a hot glue gun. That glue is hot so you'd want to be careful if the plastic is thin so it don't melt it but it dries quick and holds really well.

Thanks! I'll give it a shot.

Thick CA usually. The wires I use are Teflon coated so with a tug I can usually make them slide if need be.

5-minute epoxy should do the trick too. You just need to wait 5-minutes which can be a hassle sometimes.

Yep. Some times even thick CA is too slow for me.

Have you ever tried "Plastic Surgery? I get it at my local ACE hardware. It's thin, glues almost any type of plastic to any other type of plastic, and it dries extremely fast.

Having fun with the hot glue gun. Thanks again.

The overseas place where I started work right now, does not even have ACE Hardware. So, yeah, luckily I brought my smaller hot-melts which uses black glue sticks (doubles a lightblock) like there's no tomorrow....
What can I take apart today?

Try UV glue!

My understanding is that it bonds almost anything, and dries clear.

But I haven't had the chance to play with it yet.

Good ol' Elmers white glue works too. Just takes time to dry.

Personally I have concern about a long run endurance. You may have a quick result with a variety of glues but it can snap off along the time. I think that the best option is the CA to stick it momentarily to the place and then make the real thing with epoxy glue.

:D

Agreed. Epoxy is the most permanent fixative option I can think of.

I have used just about everything, but electrical tape is the quickest and easiest way to secure wires inside a project.

Awesome thread! I just came here looking for an answer to this very question. I will go with epoxy putty to make things definitely permanent.

Epoxy putty doesn't conduct electricity, does it?

Unless it states that it is conductive on the packaging, I'd say no, it doesn't conduct. A lot of RC modellers encase their ESCs in epoxy so it should be safe.
You could make a blob of it then just test it for conductivity with a battery, some wires and a resistored LED to make doubly sure.

I have found the liquid electric tape works great, it sound strange but it sticks like crazy and dries hard as a rock. I also use it to secure my fiber optics strands on the inside of my models and block light leaks.

I had secured LEDs into the Rebel Transporter model I've been working on with hot glue, and I made the mistake of leaving it in my car for a few hours. The heat had warmed up the hot glue and unseated the LEDs. I had used that glue to secure the LEDs into position. But that was not the least of my problems, because the heat warped the plastic, too. Huge bummer. I think next time I will use epoxy glue to secure LEDs into place, or epoxy putty or something.

Here are a few pictures of the liquid electrical tape holding in my LED and securing all my fiber optics. The other benefit is the liquid tape blocks out all the light from the fiber optic holes so only the pin point light is shown.

2 months later the hot glue is holding well. It hasn't been out of the house though and exposed to heat.

How long does the stuff take to get tacky enough to hold? Looks promising, I'm about to try my first fibers. Thanks for the info!

It is tacky as soon as you put it down, it dries super quick. I keep finding new ways to use this stuff in my model builds, it's great stuff!
