Always supply the tape then it is all yours.
If a carpenter agrees to build your fence for free if you supply the materials because he needs some proof of fence building skills to use on his resume. Does he own the fence once he is done? No he owns the pride in showing off his work on YOUR fence though before and after photos , his detailed drawings/ plans or coming to see it in person.
If you agreed to pay him an amount of money and then didn't pay him then he would have a case. If you and he never had any agreement more than food/transport/copy/credit then as long as you complete the remaining conditions of your agreement (copy and credit) you have fulfilled any legal obligation you have to him.
