I don't have a lot of experience with glues other than CA or a slow-cure version of CA I found. Urethane glues like Gorilla Glue are almost always too heavy to make it worth it and take forever to set. (IMHO, if you need to use gorilla glue on a joint, you need to redesign the joint)
Aces wrote:Hi everyone,
So far, our team has broken 10 bridges in total, with a broad range of results. This is our first year doing the competition, so we are getting up a steep learning curve. We noticed that the bridges that "cured" for 48 hours generally performed better than the bridges that cured for only 24 hours. In your experience, how long do you wait to test the bridge after you complete gluing it? Is there an optimal waiting period based on experiments? As to the competition bridge, how much time in advance do you complete building it? We noticed that room temperature definitely changes weight, but not sure how it changes performance.
