![]() ![]() Stretch girders and string them together to form basic bridges, and tap them to make them roads your vehicles can cross. I mean, the game is called Bridge Constructor Portal, so it’s no surprise you’ll be building bridges, but ensuring your structures are going to handle one vehicle, or even a whole convoy, is going to require work. Read through our advice and you’ll be well prepared for the road ahead, but if you’re in doubt, check the Best Practices page in the menu.įor more advice on thinking with Portals, check out our guide. You’ll be building a variety of bridges and ramps in Bridge Constructor Portal, so you’ll need to be aware of weights, supports, arches and more in order to get through these test chambers. Who knows, I could have been wrong about something.So you’re already a Portal pro, huh? Well that’s good, but how are you with building bridges? If you’re not the best, then welcome to Bridge Building 101, where we’ll run you through how to get from A to B. I encourage you to try things out on your own and decide for yourself what is the best way to build a bridge. Other builders might have different views and we might not agree. Disclaimer: these tips are my own opinion based out of my experience. These tips come from my years of experience starting from my time in the Science Olympiad competition and continuing beyond building for fun. These bridge building tips will give you a head start when you start designing and building your model bridges. ![]() What you want to look for in glue: drying time, price, weight, and strength. Use Lap joints whenever possible to get the best strength.Ģ5. Try steaming or soaking your wood to help it bend.Ģ4. Basswood will bend easier than Balsa wood. Remember to close your glue bottle when you are done using it.Ģ3. Doing can also help the glue to seep into porous wood like low density Balsa, creating a stronger joint.Ģ2. When using Elmer’s or Titebond wood glue, you can mix in a little water to cut down on weight. CA glue is a fairly strong, light, fast-drying glue used by many builders.Ģ0. Wood has about the same strength in tension, no matter how long it is.ġ9. Different trusses have different ways of spreading out the load.ġ8.

Good lighting when working will help you perfect those little details.ġ5. By cutting a piece in half, you more than double its strength in compression.ġ4. Most mistakes are made when you aren’t paying attention.ġ3. Always keep safety in mind when using sharp tools. You may get a clue on what failed first.ġ2. Record notes and dimensions you won’t remember later on.ġ1. It’s still true, measure twice and cut once.ġ0. It is cheaper to buy Balsa in sheets and cut your own wood strips.ĩ. Balsa wood comes in a wide range of densities and stiffness. An L-beam is more efficient than a square, but harder to build.ħ. Keep your bridge from twisting by using lateral bracing.Ħ. The more bridges you build, the better your construction skills will be.ĥ. Keep your hands clean!
