Lighthouse lens

[MRC]

I'm working on Shipyards lighthouse Utö. The scale is quite large: 1:72, and it give me the possibility to reproduce the original lens. It's maddening! 😁 Anyone who have tried such work, and probably find a simpler way to this kind of work? The lense's valves are made with printed overhead film ( I used msPaint), cut and glued with UHU plastic.The frame is made with 0.5 mm painted paper. Tips and tricks are welcome.

Dear MRC:
Go forth and Push the envelope, Looks good so far, I think you should go the whole way and put a LED bulb in the Lens and get a board that will have it blink in sequence.
We must have a electrical engineer here who would help with the electrical stuff
Good Luck,
Miles

Forgive me for intruding on your build thread. I do not know what Swedish stores offer, but in the US, craft stores and remainder stores sell LED "tea lights" and "votive lights" by the bagful and they are also available on Amazon. You can find ones with a constant light, ones that flicker like candles or flashers if you look around. Low end LED flashlights that produce either a constant beam or flash are inexpensive. If you have basic soldering skills, it would not be too hard to take one of these light sources apart, add a length of wire to the LED and install it in your light house model. Be sure to use a low power LED light source. The LEDs of the bright high output flashlights that are coming on the market get hot.

It a Fresnel lens. Available cheaply in thin flexible plastic. A quick look at Amazon found ten credit card size sheets for under three dollars. Sold as a flat magnifier but search on "Fresnel." If you light your model the Fresnel sheets will look correct. Since it is a real lens, be sure you test each side with a light before determining a surface and committing a cut.

Christian- excellent tip indeed!

For small lenses on tiny models, I use a Humbrol - a liquid gel that you apply with a needle or tooth pick. Dries clear. Plastic modellers' also it to attach canopies.

Lighthouse at 1:72.
Two flashing LEDs - red 3 mm, 5 mm white.

Oooh. Lighting in paper models. One of my dreams. I still want to experiment with fiberoptics on a spacecraft dashboard. Already have the fibers, still need to do a model for it. Somewhere in the coming years, I hope, I'll do Ken West's Apollo capsule and I will stash it with fiberoptics on the instrument panel. I swear I will.

The lens in on place, temporarily. I want to see how it looks before I'll glue it on the drum...The real lens as a comparison, a terribly complicated work to reproduce. 😊

I'm curious about this lighthouse, what character is? Is a sector light? I've never seen a similar one. Are the white and red altenate? ( a lighthouse nerd like me cannot let such a conundrum be unanswered :-) )��

A good source for very small LEDs for hobby work. The website has videos on how to use the products. They sell to people who are making scale model lighthouses.
Reliable company, good customer service and they do ship outside of the USA.

They make a slow warning flasher that comes in white or red.
