Most varnishes only require sanding after a hardening period of around 7 days. You may sand some coats eg after say the second to remove the bits that lift up and after the 5th and say 11 th but it would be a light sanding with probably a much finer paper say 400. It sounds like you are taking too much off and it may not be hard enough in the temperature you have. They are washboards not fine furniture.
