How many pumps?

Posted by Kyle on Jan 19, 2005

I have some 8th grade students building a Ches. 16 as a class project from plans. They have done an excellent job so far. Tomorrow we plan to lay the bottom glass. Since class is so short (50 mins.)we need to be as accurate with mixing the epoxy as possible. My question is....How many pumps do you think we will need to mix to set the glass to the bottom of the hull?
