The goldstar tandy dies are not compatible, the gold star press upper die is threaded. A set screw holds the tandy press upper die. The goldstar dies cost less and does a good job with rivets,snaps
I have the both, tandy press with the BRL adapter/die for ( not the centering jig) punching holes and the Goldstar for rivets and snaps. Goldstar does not sell the die for punching holes in leather they didnt when I got mine 2 yrs ago.
