After I got everything to work. I set the oven at 350 degrees and heated the Kydex.. I checked it every minute and when it was soft enough I screwed it to the back of the Terrapin and rolled it in a towel, immediately afterwards, I put it under my mattress for about 20 minutes..
Tips:
1- When you roll it into the towel always apply pressure to get a tight wrap..
2- The sides were the hardest to conform, so when you put it under the mattress, make sure you don't lay the RF flat, stand it on it's side..
3- Be carful not to over heat the Kydex…
The screw:
Once you get the Kydex - go to Home Depot and find something that will work for you. I found a screw in my tool box which I used with a washer and it worked well, I did have to cut a piece off.
I hope this helped.. If you have any questions, you know where to find me.. LOL
