So is this Gorilla Glue, or PL 400 (construction glue) or xxxx can you name a/the brand, just so we get it right as this seems the key element in the design. Or is this some type of glue you accessed from your place of work?
As this first one was experimental in design, I used two different types of glue; one for 3 laths, the other for 4. One was a variety of Gorilla Glue, and believe it or not, the other was simply Super Glue. The first key is to cut off the clear, plastic "pocket coating" on the outside so you are down to the actual vinyl(?) binder itself. Then, place the glue directly on the binder and firmly press, then weight, the laths in place. The three laths I did with Super Glue required about 2/3 a tube for each one, but proved just as sturdy and adherent as the ones done with Gorilla Glue. Besides getting a regular workout at home, it has traveled to KC and North TX with no signs of faltering.
EDIT: This design holds the entire MMP map set, with duplicates (!) of all but the Fort boards. I'm planning on making another for TPP maps and will use the exact same method. I've thought of making a tutorial video on the process and materials, but even though I have a fancier phone now, I'm not sure how to make a video yet, let alone post it on YouTube.
