Hi guys, I have built a few planes from scratch and have always used p.v.a. glues. I know this can be a bit heavy , but I have been told that c.a. glues form a brittle joint, and that cant be good, can it?. If the use of c.a. is best , would it be a very thin type or a thick one. I intend to build a 50 ins span volks plane. I think the full scale job is a home build. Thanks in advance Bill.
