Large batch of soap

I received a fairly large order for some soap over the weekend. I've been trying to figure out a better, more efficient method of making my soap. Not changing it in anyway, but increasing production and decreasing labor costs. Last night I had the first opportunity to try out one of many ideas I've toyed with. I tripled my soap recipe. I have read in numerous books and blogs that as long as you can do the math, you can increase or decrease the size of your soap batches. I put that to the test last night and it looks like my math was good! This soap will now cure for a day then I'll need to grate it for hand milling. My normal method of hand grating the soap worked a lot better before I tripled the recipe! I'm now trying to think of a more efficient way to grate it without dumping a lot of money into a machine--which I may do eventually. For now, I think my best bet is to enlist the labor of my teen-age son!
