Well the obvious answer is from harvesting materials from other planets, moons and asteroids.
Yeah, like millions of them.
To go on this subtopic. To be able to even get so much material to harvest planets for the raw materials in them, you'd need to be able to travel extremely vast distances in unbelievable large and capable ship. Scale would be required here, as you'd have to store the materials harvested somewhere on board.
But before you even get to this point, you'd have to build this vessel in space, outside of the orbit and gravitational pull (far enough away to not crash back into the planet), which actually leads to the next problem. The ship (or ships) would have to be the size of the planet or larger. With extremely vast management crews or automation systems (AI).
These ships would have to be able to self repair, along with self replicate (almost breeding) as sending more ships from the home planet would take forever. Literally millions of light years to get to wherever the "original" ship is now at.
Being able to produce new planetary mining ships in space would be an absolute necessity for anything like this. Which if you can do this, and travel the vastness of your galaxy to harvest the raw materials to be able to make a Dyson Sphere, you'd be better off just building a ton of ultra fast ships that get sent out in ever direction searching for life.

OK We'll go on this tangent - the new "deathstar" from the new movie doesn't move. It stays where it is, it just shoots an energy beam across light years and destroys other planets. Frankly that whole thing was just DUMB! and with that I must walk away before I just cry over how bad things like this were in the new movie.. and why? for the love of star wars? why did we need another deathstar for a super weapon? and why this crazy impossible thing.
The movie's plot was so horrible in that the concept of "a planet can't be blown up from a well placed torpedo" But when you suck the energy out of a star and kill the star, you've killed the planet.
The star would likely go super nova and blow away the entire solar system.
So many problems with this movie - but since we assume that the planet doesn't move - and they used the weapon to destroy the planets of the New Republic (how the hell did an energy beam split mid flight with no prism?), and the sun was glowing when we visited the planet - the crazyness I read is that Starkiller base only took the outer layer of the sun - OMG I just have to stop..

Not exactly. All you have to do is to jump-start the whole process by sending robots and mining equipment to a small planet. Getting raw materials to orbit would be relatively easy, because of lower gravity force, and initial harvested energy would be delivered to mining equipment on the planet, greatly increasing output over time, as more and more energy collectors orbit the sun. Once you're done with one planet, move to another. Rinse and repeat.

I really wish they had just made the Thrawn trilogy into movies instead of making A New Hope 2.0.
Exactly. I don't even consider the new one to BE Star Wars. It's Disney Wars.

The split, from what I read, was done at the emitter. The angle of deflection over those vast distances would be fractions of a degree at the point of origin. The biggest issue I have is that they would see this coming and would have hundreds of thousands of years (it's for all intents and purposes just light) to evacuate the planet.

The harvesting of the raw materials is easy in comparison, but you still need power to do it (an unbelievable amount of power). You can't be spending centuries chewing through a planet.
It would have to be done in a scale of a few years (worst case). Longer than that and you get into the "fix it stage" where your equipment is breaking down so often that you can't possibly replace it fast enough to keep a forward going pace.

The hand waving here. Just start blowing chunks off the planet and using ion engines to push it toward the home planet (or wherever you are doing processing) it could take millions of years but if you start closer you could have a constant stream of these coming in.

Not possible in a few years right now, but closer to a century. If things break, that's what you have robots for. And once we have the capability to actually send robotic mining crew to a different planet, I think we would be capable of building them to last a few decades.
You have all the power available already, from nearby star.

The scale of an Ion cannon capable of blowing away usable chunks of a planet is an even greater challenge. It would be far easier to send down massive mining systems to each planet and have the resources funneled to the mining ships.

Solar power is great, but this only goes so far, you have storms/clouds etc on planets. All of which effect solar power. If we're talking CrapWars death-planet thing, this is completely unreasonable, as discussed.

You wouldn't use an ion cannon for that. You would use a rail cannon or something kinetic.

Again this is completely impractical to start. The size of it would have to be as big as the planet to do the job efficiently. Which would take an entire planet to just make.

I know why you say that, but I'm not sure I agree. Disney of course has their name all over things, but Lucas Film is still mostly allowed to run itself.

Look at this from our point of view.
Human started digging with our hands, and then basic tools, to dynamite, to heavy machinery.
The next scale up would be earth movies like what Caterpillar makes (these things are huge, 5 stories tall etc) this is real world uses.
And it will still take us hundreds of years to just clear out the worlds largest copper mine in Mexico.
Only with going to bigger and faster more reliable equipment would it be feasible to do this. Ion Cannons or Rail Guns etc are all completely impractical to begin this with, by a sheer amount of resources needed to make it useful.
They'd be better off planting a bomb big enough in the planet to crack the planet into pieces. At least this is practical in a sense that it could be done.
Harvest reactive material on a massive scale (use modest mining technology) and plant the bomb(s) and have them timed to go off at the exact same time.

Planet like Mercury hardly has any atmosphere so solar power is perfectly applicable there. Venus would be more challenging, but we can always convert solar into microwave and beam it to the station on surface. Sulphuric acid in atmosphere poses bigger problem than supplying energy there.
Originally we were talking about Kardaschew Type II civilization, which could potentially build Dyson sphere (rather impossible), but more realistically would build Dyson swarm, and that's something even humans could build in about a century.
