Adamantite Ore can only be harvested every 36 minutes. It takes five Ore to make a Nugget and you get 15-21 Ore each time. Every ARM and BSM Red Scrip item (bar the Aurum Regis Creasing Knife and five Scrip Titanium Ingots) requires 3+ Adamantite Nuggets. This puts a floor on how long it takes to cap Scrip on those classes that the other crafting classes don't have.

These items should be balanced around how much Adamantite they require since it's the choke point. They are not. A starred Adamantite Greatsword requires four Nuggets and gives 62 Scrip (15.5 Scrip per Nugget) but a starred Adamantite Alembic requires five Nuggets and gives 40 Scrip (8 Scrip per Nugget). So--assuming 15 Ore per trip--it takes 11 harvests to cap off of Swords and 20 to cap off of Alembics; and this is just today's example.

Please, in 4.0: a) Don't make some crafting professions reliant on timed nodes and others not; and b) Weight your rewards around the timed items.
