Hoshi-Goya (Grain Dryer) Scripting

As you may know im working on a Japanese expansion that based on historically accurate information. Part of this is cutting grains like barley into a sheave and then drying it for use. The Hoshi-goya is the dryer that i have made and I have decided to use the Oast house script for it to work.  I've created the recipes to be used, have the items and products to be dried and rezzed after the drying time ends.  The HG needs to show the sheaves drying.  So my question is, as a non-scripter, how do i accomplish that?

The sheaves need to be on the inside rails, hanging when in use.   gyazo.com/167749122f15f3c2fd01af9182bcf632
Then they need to be invisible when not in use.
