I added some explanation to where the sprayer section is. If you tell me what you need to know about it perhaps I can adjust my explanation so it makes sense. What I posted was directed more by what photos I had than anything. It's been about 2 months since we built it, so memory of what imporant details I might point out sometimes escapes me.
I've posted all I have for the moment. If you have questions you want answered, let me know and I'll try to provide answers.
