basically, building a track and i'm looking to get a tunnel thats 5 or 6 long straights long, and was hoping ot stick some led's in it, anyone any idea how to make a tunnel as i was hopin to have it sort of half-oval rather than straight edged?

any pics would be great of the construction

thanks

Do you mean 5-6 car lengths?

 

[darrenmcc]

nah 5-6 long stright track piece lengths

No,

Have you got a big pole with a hook at the end?

Darren, my tunnel is only about 2' long, but access for maintenence of the track is essential, so that is something to bear in mind with a long tunnel.

Regards, Lloyd

yeah, due to the length, i was hopin for maybe 1 or 2 "flaps" just to get access into it

Depending on the height clearance that you want, you could possibly use a large cardboard tube and cut it in half-ish as your base. Another option would be PVC pipe similarly cut. Of course, things are simpler if you'll accept a square profile rather than the round one.

Hello darrenmcc

The wery best is some kind of a waterpipe in plastic just cut one third of the diameter and then press the rest together.

If it's straight, as you say, you could ( conceivably) make a series of identical profiles of the opening shape from MDF, connect them with stingers that will establish the long dimension, and provide a surface to attach the tunnel "skin" which could be card stock or something like this:

Essentially like building a balsa airplane model fuselage, but inside out.

I saw a preformed tunnel for either O or G scale model railroads and wondered if that might work. Price was cheap but no room in the luggage

to take on the plane so left it behind. They are molded styrene or the like and look similar to Route66's tunnel (well not exactly like that but I think you get my drift.... thin shell painted on outside open inside).

Just a thought... maybe check out the model RR sites for some ideas? Their scenery books have many ideas in them.

Cheers!
