We bought a piece of square PVC downspout from LowesI know someone who uses 4" PVC pipe to make round soap molds but of course no waves.

Yes, you can cut it down. I make a little over 4lbs at a time as that is what fits in my mold and my soap cutter. I get 12 4 oz bars which is plenty. I like making different ones; I wouldn't want 40 of the same thing.

This is the lye calculator that I use. After you enter the weights of the individual oils for the original recipes and hit the calculate lye recipe it will give you a place to resize the recipe.
This is how you can tell how much soap your mold will hold.
Length of mold x Width of mold x Height of soap x .40 = ounces of oil needed
I used olive oil and lard. The shrinking happened when I milled the soap and repoured it into molds. The milling recipe called for 12 ounces of grated soap and 9 ounces of water, heated together to re-melt it so you could add color, scents or other stuff, and repour it into molds.@norseofcourse ...your soap shouldn't shrink that much; or deform. That is not a problem I have run into or even read about. What kinds of oil did you use?
