This is right on target for $ 100 per hour, which is the minimum I can be comfortable with.  There is no warranty, just the opinion that this is a temporary, viable alternative to replacing the block.  As to how  the CA works,  I think it is because it greatly increases the surface area of the wood ( at the molecular level) in contact with the pin. There may be some swelling of the wood involved, but I don't know about that.
