8 diameters = about 1.5 ", got it. I'm a newbie! Full stem ahead, I'm going for it today! Thanks again.

You got it. A "diameter" just refers to the diameter of whatever hole you're drilling or fastener you're using. So, for instance, if you were designing a super-strong structural connection with 1/2-inch bolts, then you wouldn't want them spaced more than 8 diameters apart, or about 4 inches (8 * 0.5 = 4).

Anyways, end of the math lesson. Good luck, and good work!

Sorry for the segue but how is the bonding capability of that material? I'm thinking about bonding some light windows into foam/fiberglass panels and ditching mechanical fasteners. I'd like it fairly strong of course, but not so tough that I couldn't chisel them out at some point.

Based on some videos I've seen online of custom trailer construction, we could pretty much eliminate fasteners if we wanted.
