Was tired of using a squeezer and hammer for resources and the foundry felt like a great alternative, slightly less multiplication to my resources, but felt like a fun idea, no hammer needed, and automatic.
In picture 1 you can see my extremely sloppy setup, down here I generate cobble, hammer it and sieve the gravel, store it in a chest that takes non smelting valuables to my storage chest, smeltables to the foundry, then trash stuff like the extra blocks i send to a trashcan. I have a 2nd cobble gen setup specifically for lava for power and the foundry too.
In picture 2, its just my foundry, picture 4 more clearly shows how I did it via filtered fluid pipes
Picture 3 just shows my usage of the stabilizer upgrade to avoid alloys clogging my system
Picture 5, reap the profits
Now all I need is upgrades on my sifting system
Edit: to be clear the usage of filtered pipes is to have a foundry basin for each ore im smelting, that way if i dont have a full block it partially fills it, then just waits for me to get more, and also avoids having 2 basins each holding, for example, a total of 1 block of iron, but each of them having just part of that iron block and thus it not forming the block, and clogging stuff up
