There is nothing like trying to wrestle with a greased pig. That's a little what it felt like trying to hold on to fiberglass cloth.
Here are the results of the 3 tests I ran. The final one was the one where I had the best grip on the cloth.
As opposed to the earlier tests with Por15 and Epoxy, the cloth by itself would stretch some. Once the Por or Epoxy was applied, there was no stretching. It just held until it broke.

As you can see, things pulled apart in different directions.
Tried running this test 3 different times. Trying to hold on to the fiberglass was a bit of a trip.
Eventually, I rolled up each end like the above pic, that gave some substance to pinch between the pieces of plywood, trying to hold the ends there.

Here I measured the thickness of the Epoxy coated fiberglass cloth.
It measures roughly .025 in thickness.
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.

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.

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.

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.....

Well, I finally blew it up.
Wasn't trying to.
But it happened.
I was in the middle of testing the strength of 2 different items, when the one gave up the ghost sooner than I thought, and when it did, pieces started to fly that weren't supposed to.
As a result, my scale is now broken.
That's the thing about electronics. The screens don't take very much abuse. One good punch to the face, and it's all over. The left side of the screen still has a little display, but the rest is history.
Another one is on the way, so I can finish the test and post the results, hopefully, within a few days.
