I have a 8"x6" Mold Max 30 mold that I recently finished, and upon filling it with water to approximate the amount of resin needed I noticed it leaks a bit at the bottom seam.
The gate I created at the bottom of the mold is only about 1/4" from the edge and I'm concerned that might be part of the problem. I also use rubber bands (size 64) against a cardboard backing, and while they stretch fairly well they don't seem to be as tight as I would like. Doubling the bands creates a bit more stress and I'm worried about warping the casts or damaging the mold. ...I never anticipated researching rubber band sizes, but here I am.
I'm curious if this is as simple as getting the right size rubber band or if I'm in trouble as a result of my gate distance to the edge? I'm also curious if the slightly higher viscosity of Smooth Cast might prevent it from leaking versus water? If it's the gate distance to the edge, I'm wondering if anyone has any suggestions? I'm willing to add a little to the bottom but I'm not sure it will work.
Thanks for reading, and any help would be greatly appreciated.
