Yeah that would work if the mining ship has industrial replicators - which would require massive amounts of energy to run but the ship does have massive amounts of energy after all.
And you know this how?
It's how transporters work.
Actually, I was asking you how you know the Narada does not have massive amounts of energy.
I suspect that industrial replicators could be modified to construct torpedoes but standard replicators couldn't 'construct' the energy needed to power the explosion.
Which again begs the question of how you know the Narada doesn't have an industrial replicator.
It further complicates matters that you are under the mistaken impression that replicators make physical materials out of pure energy. They don't; even industrial replicators can only rearrange raw materials into a desired finished product. The hard part, actually, is finding the materials; you'd need a gigantic mining ship and twenty five years of nothing-better-to-do just to think about it.
How much of that 3 miles is for ore storage, the energy required to power the drill, and the ship's self repair tech? My point is it's not a warship.
You're right, it's a gigantic industrial platform designed to capture and process asteroids as the first input of whatever-it-is the Romulans use that ore fore. Essentially, it's a giant factory ship.
If we were talking about a warship, you might have a point (warships usually have to return to their home port to rearm and refuel). The Narada is somewhat unlikely to have this problem, both because of its size and industrial nature.
I don't doubt that they could replicate the components for torpedoes but energising them will take specialist equipment
I will not even enquire as to how you know this, since you have no idea what the warheads are made of or how they are primed.
For all we know the Romulans were using ordinary bilitrium; if they took the time to obtain an antimatter converter in the 24th century (or even stole one from the Klingons in the 23rd century, which would explain the attack on Rura'Penthe) then they could have made as many torpedoes as they wanted just by finding a plentiful source of bilitrium ore.
Being from the future, they would have known where to find a plentiful vein of that ore that no one else (yet) knew about.
They might order stuff off the romulan internet (subject to delivery dates and the distraction of romulan porn) but it's daft to say that making something more powerful is so simple.
More powerful than what? There's nothing to indicate a 24th century Starfleet ship would have done anything but laugh at those torpedoes. But even a pipe bomb looks like a formidable military weapon if you're using it in the 1850s.
My brother worked as a gunsmith. I think your time-travelling Hamas would have a hard time finding components of sufficient quality to manufacture the machinery they need to construct their modern weapons let alone access to the raw materials.
Are you aware that the Narada is a MINING vessel? Meaning it is implied that the ship has both the machinery and the capacity to get those raw materials in part of its design?
Modern Taliban doesn't manufacture its own weapons for similar reasons, despite having access to the knowledge. They import them in from nations with the technology.
What they don't have--unlike Nero--is access to a gigantic mobile platform packed with industrial equipment and 25 years of spare time to figure out the most effective way to use it.
They tend to be limited to making crude explosive devices on their own.
Narada's torpedoes looked rather crude to me, especially since they were drop-launched from what were essentially bolt-on missile silos attached to the arms of the ship.
