We are starting to manufacture jack lines for sailboats. They are constructed from 9800 pound polyester webbing with a sewn eye in each end. When we sew the eye we have to calculate how to sew it so it has the required 5000 pound strength. Knowing the thread size tells us the theoretical strength per stitch. Then it is easy to calculate how many stitches are required to produce the necessary strength. The question is does this really work? The only way to tell is to load test samples.
Most of what we test does not require a tree on one end and dump truck on the other. Even with this set up our first attempt resulted in pulling the dump truck up the driveway with 4000 pounds of load. A bit of weight in the bed and using the real brakes rather than the parking brake fixed that problem.
5000 pounds came and went without any damage to the stitching so we know that our design works and we can go in to production.
Do you need to re-glue a stretcher in your old chair? The problem always seems to be how to you keep everything tight while the glue is curing. A simple solution is a cam buckle strap. You can pull them quite tight and the cam buckle holds right where you want it.
After the glue has cured, it is easy to release and you can use the strap over and over again.
