Building a New Ruuder
Thanks for a very easy-to-follow description. Your writing is very clear and just detailed enough.
One quick question. I''ve worked with two-part expanding closed-cell foam before. How did you calculate the starting volume so that you''d get just a bit more, instead of just a bit less, than you needed to fill up that cavity? <em>"…about 4 times its liquid volume"</em> sounds like a vague guidline.
