Unfortunately once the foam pad perishes or wears out there is no replacement other than to buy a new machine. Corby explained to me that they used to take them in to replace the pad but because there are special rivets that fan out into the wood it makes it very uneconomical for them to remove these in order to set the new pad. Rather sad seeing that the machine's life expectancy is only as good as the foam in the press! Sadly a machine that is in good order has to go to the tip when only the foam pad wears out :-(
