Learning new stuff.. I'm attempting shaping high density foam for making Land Rover seats ( the foam is sold by Clarke rubber here , cut to size , but not shaped ) .. CMP seats are a squarish block, easy, but some seats require a radius here and there . The professionals apparently use a kitchen electric carving knife - as used for carving the XMAS turkey

.
Has anyone done this ? Jim .. F8 man ?
tips here
