I'm currently working on finding a stronger and tougher end cone for torsion springs. Presently my design is using the overhead door standard of a cast aluminum part. These are about the best parts for the cost, but it seems they have a tendency to crack in our application. Is there a...
I’m on a quest to safely wind a torsion spring. My search has turned up something called the EZ-Set torsion spring system; however, I would like other possible ideas. I believe the EZ-Set torsion spring system will not work with the spring I’m looking to torque. The spring that needs torque...
I am faced with a design problem that involves welding bending a flat plate. The flat plate is 23.5x23.5x.38 –inches. I’m welding a two 3.00x3.00-inch tubes about 9 inches apart along the center line of the plate. In addition I’m welding 2 L brackets near the center of the plate about 3...
I'm working on a project which involves an inductive sensor detecting a flag. The flag is currently made of 430 SST and is 12mm wide. The sensor is a 12mm sensor with a nominal sensing range of 2mm. The flag is on a roller and rotates at an unknown speed with the sensor mounted over the...
I'm designing a cover for a piece of equipment that may impact a vehicle. This impact will be at a speed no faster than 5 ft/s and could be parallel or perpendicular to the painted surface. This cover will be made of PVC and I get to choose the durometer of that PVC. What durometer of PVC...
