This is mostly an Ankerstein construction, but the bridge is not, and that is mostly what this post is intended to be about.
In their Golden Age, many Anchor Block sets were available with metal bridge parts. Many of the online plans feature bridges.
I have various old metal bridge parts in various sets. They look old and bent and rusty. They go well with the old weathered and worn stones in those sets. They don't fit in quite so well with the new stones. I prefer to build with new stones.
One can buy lovely new reproduction bridge parts from my favorite Ankerstein source, The ToyHouse. I hope to do so eventually, shortly after winning Lotto.
In the meantime, I wanted to build more bridges. I wanted to do it in a way I could commend to my readers as readily available.
One technique is based on plastic models. I may come back to that. I have posted a picture previously.
But the other day I ran across a paper punch in Big Lots that could help me make bridges out of cardstock. If you are handy with a craft knife, you can probably build better bridges than I built. But my punch technique does work, as you can see above, and I will be using it to build more bridges. I need to get some gray cardstock that will photograph better.
Aside from that, I have been building, with Tinkertoys, Lincoln Logs, Roy Toy, and K'nex, and will be blogging some of what I have built.
Mostly bridges. I like bridges.
Good block play.
