Yes I will ask for a copy of the contract before they continue, and the problem isn't with the boy, but the scout leader. We give them all the access they need during reasonable shop hours and also building time as well. Because of the nature of our place they cannot be left alone where they are building for their safety and the safety of the animals around them.
I was not the one that hammered the contract out with them, but he keeps demanding repayment for the building materials. They have already started and if it doesn't get completed soon he will have to miss this batch of eagle scouts and join the next one.
We have done many projects with the scouts, and enjoy doing them, but this one seems different and more of a problem then a help.
