I am on this phase right now, could only get about 3 blue science going.

I either couldn't get enough cogs or miners or iron.

Then I remembered that it's really no shame in destroying stuff to make it work.

I think my key is to make sure you have an abundance of iron being produced, then the cogs, then the miners.

But do them off site somewhere, there's no need for them to be right next door, and just run the belts into your science manufacturing.

So, yeah, create abundances of resources, make other stuff in plenty of space, and don't be afraid to run belts for long distances.

I don't know the ratios, but you'll need about 10 of each furnaces, cog makers and miner makers for good production.
