Do I need special equipment for sandcarving large substrates?
When it comes to sandcarving, the sky is the limit. You can blast any size item, whether a boulder in someone’s yard, a large donor wall (brick or glass typically), or a monument that is fixed to the ground. If the item doesn’t fit in your current machine, you can purchase a portable pressure pot, or you can design your cabinet size (up to your specs) with your sandcarving dealer.
