Ok. New scale on the way. Should be here tomorrow. This one is good for 600 lbs instead of only 300.

Hopefully, I can keep this one in one pieces.

The S hook looks like it might not hold 660 Lbs. I would stand under it with that weight hanging on it.

No problem. I will gladly let you stand under it with the weight on it! Lol.....

Ok, then. I finally got my testing apparatus fixed up again, since the new scale came in.

Here is a piece of fiberglass cloth - 1 single layer of cloth - with Epoxy resin covering it on both sides.

It is clamped in between pieced of plywood, which are hooked up to the bottom of the scale, and the bottom end, chained to a 2 x 3 to apply pressure.

This photo was taken at about the max pull weight, showing 455 lbs.

Next step was to take a piece of fiberglass cloth, and coat it with Por15 this time, on both sides. Using the same setup like before.

This was also taken right before failure. Showing 405 lbs.

Here I measured the thickness of the Epoxy coated fiberglass cloth.

It measures roughly .025 in thickness.

[image]

Then I also measured the thickness with the Por15 over fiberglass cloth.
This also measures about the same thickness at .025.

So, there is a little difference as to when it failed, although not a huge amount. The test setup could have accounted for some of that, by not being fully square.

Fortunately, I did not trash the new scale in these tests. That's a plus.
