Coffee Tin Tunnels,
Was created the same time I decided to build a Lego train set running through my living room, then my bedroom and closet as well. The hardest part of building the support structure was not how I was going to drill through the walls of our home, but was in fact, getting my wife to allow any train running through her living room.
The support shelf is chin level, mine that is, so that, well, lots of reasons, I will cover them all later in following MoC’s.
Yes they really are Coffee Tins, an 8 inch hole saw used to cut through the three sections of wall where I wanted the tunnels. I then used a product to insulate the wall after making most of it expand into dust.
Large Maxwell House coffee tins were then incorporated. Both ends obviously needed to be cut off, then, cut down the side to reach the desired dimension. Once spread and placed in the Hole in the Wall, they were fastened with wood screws. The interior of the coffee tin was also spray painted flat black.
There is about a 3 inch gap created when spreading the tin, your hole when drilled in the wall must allow for this, in other words, you first drill your 8 inch hole about 2 inches below your finished grade. I think you’ll see what I mean from the pictures that follow. Feel free to ask any construction questions.
I hope you enjoy the pictures, I’ll be showing my finest Lego moments soon on “The Train Set My Wife Let Me Build in Her Living Room”
P.S. She loves it, and the Grandkids go nuts for it
