For this balsa wood bridge, I used a ‘K-Truss’ design with seven vertical members and 6 ‘K-Trusses’ per side. The K’s were the most challenging part of the build, because I had to calculate each ones length, and the approximate measure of the angle I had to cut into each one. All in all, the bridge took around 10 hours of work over a three-day weekend (plus glue-drying time, of course). This website is where I originally found the ‘K-Truss’ […]
I recently had to do a project with limited popsicle sticks could only use school glue, and had to span two feet. The bridge also had to hold a loading dock holding a bucket full of weights. I knew a truss bridge was the way to go but didn’t know which kind exactly. Your site inspired me, and so far my bridge has not even bent.
A revolutionary way to bend wood when building arched model bridges. This method is so simple it will blow your mind, but it really works.
This is a free bridge builder game that I found and it is pretty neat. Construct a bridge and test your building skills. Help your people gather items located on the other side of valley.
Building popsicle stick bridges is one of my favorite activities to do in my spare time. I have built many popsicle bridges over the years, and love coming up with new designs. A huge focus of my bridges is designing blueprints that are easy to build and structurally sound at the same time. You can purchase many of my plans and blueprints in my store.
Building a model bridge is one of the most rewarding hobbies I have done in my entire life . I have learned a ton about working with wood and tools. I have also learned the basics in bridge engineering, and have a greater appreciation for real bridges. Model bridge building has also given me a originative outlet that I can share with others. Not only does it give me something fun to do, I can show off my creations and attest to their abilities.
To help clear up any confusion when I talk about the “efficiency” or “efficiency score” of the bridges I build. This is a mathematical equation to determine how well a bridge performed
This kit is actually one of my first introductions to building model bridges. My mother bought this for me one year, thinking that I might like to build a model bridge kit. This bridge building kit from Amazon actually has three different bridges. It comes with all the supplies you need to build a suspension bridge, a truss bridge, and an arch bridge. All of these combined make this kit an excellent gift idea, or something you can build just for fun
This is the absolute best video I have seen about building model bridges. Roy Coleman, the founder of the International Bridge Building Contest, gives a very informative presentation in this video. The presentation is over an hour long. He shows how to build a bridge from scratch. He is gearing his video towards the…
I want to put x-shaped supports on my bridge, but I don’t know how best to join them. I’ve heard of something, I think it’s called a half-lap joint, that I think might work best. You cut half of the wood off the part of the strip that will be the actual joint, and then connect the two pieces at those joint parts. There isn’t any part of the wood sticking out, and they are very connected, I think, as far as how the weight/force is distributed, which I figured would be good. But is there a better way to make an x
