I am selling a skeleton grinder that produces very high amounts of bones without actually having to hit the skeletons. It works by skeletons spawning, moving along a canal and then been crushed by 4 pistons. This does not produce xp but produces very high amounts of bones and arrows which sell really well. I am asking for 15,000 rupees I will sell this grinder to the first person who posts saying they will buy it.

Okey, yeah, I saw this in a 1.2 preview video on youtube, and it didn't work, but maybe it is changed in 1.2.5?
Well I want to wait a bit and see if I get a full offer of 15k. If I don't then I will sell to you for 11.5k
