sry, it took so long just finished the alpha for my mod and released it today . Anyways, did the GUI, Greenish gray Coin, buffed the looks of the washer and repackaged it , also repackage the coin as well just encase you liked it. Gave you the Mechanic as a zombie and a villager. I am not sure if the villager looks right; I couldn't spawn one to see . Like always in the spoiler below and edits are always welcome.
...I presume one of the two bars are for the BuildCraft liquid thing, right? Well, bad news: IIRC, the bar is much, much bigger. For an example, check out any of Forestry's machines, most of them use BC liquid.
