I´m from Germany. I watched nearly every video at your club side. That was the reason for me to start working with EPP. Before I found your webside I only flow depron planes.
I used your instructions to build my foam cutter.
I use 20g/dm³ EPP. I think, that must be the same as your 1.3
btw how long is your cutting bow for the assassin? Is it the shown 40" bow?
Below two pictures of my foam cutter and my "copy-pinata"
