My Ani SD has been on hold for a while but I am getting back to it. One of the problems is that with such huge slabs of flat resin there is a problem of warping, actually flatening of the lower hull. I came up with a simple soultion to this. Instead of some elaborate inner structure that requires figuring out angles and math and stuff, I came up with this. I will use "V" shaped strips of 3mm aluminum strip. These will be bent, clamped and epoxied to the lower hull. This should keep the lower hull from ever flatening out.
