I have been searching the web for some time now. I badly want to make a simple, but effective, zombie pigman farm without more than 2 days work. Any links, help, or suggestions on how I can do this would be really nice.
My approach to overworld farm was:
But that's more than 2 days of work unfortunately but I'm afraid you won't do much better for overworld survival...
Anyway, some highlights:
EDIT: Some pics, as requested. The spawner while under development. I had decided to start 22 blocks above the ground, which, in hindsight, was a waste of time and resources. It would likely be much easier to dig a 22-block pit instead and start at ground level. Nevertheless, what you see:
Now, making a mini version of that.
Lava every third block
That forms two lava walls.
Pour water to form two walls of cobble. There will be mistakes and imperfections. Don't worry.
Create cast for the bottom of the portals. Seal any holes resulting from imperfect walls. Pour lava in Solidify. Cast for portal walls Lava Water. Repeat three times. Another layer of portal floors/bottoms And more walls.
Remove all the cobble
And light that up.
Turning that into actual grinder is left as an exercise to the reader.
The process is the same as building a normal grinder if you do it in the Nether.
You can build one in the overworld out of portals, as detailed on the wiki:
Another way, is to get above the roof of the nether (use an ender pearl on the top layer of bedrock on the roof) then build your spawning pads about 128 above the base (so no spawning in the "main" part of the nether). It's a standard mob farm then, but without all the pesky clearing that you normally have to do in the nether to get decent spawn rates.
