5 years I have been looking at the ends of the terracotta chimney flue
liners I used for tunnels. I couldn't decide on what to use for a tunnel
portal. This past spring I bought a good Rigid table saw and a portable
compressor that came with three nail guns. The 18gauge gun seemed
perfect for building 1/29 structures. I also got a 23gauge pin nailer
for really small stuff.
the right tools makes all the difference in the world. I cut down some
scrap PT 4x4 I found on someone's curb and built these tunnel ports. I
had seen a picture of a wooden portal with the braces as shown. I liked
the affect and incorporated into my design. I made these up as I went,
cutting and nailing. I could not have done it with out the right tools.
Finally, after 5 years I have tunnel portals hiding the flue liners.
