I’m teaching some CP classes. For the basic introduction classes I’m using PVC pipe. Works great. However for the advance classes I really needed a loaf mold. It’s kind of hard to do a swirl soap in a PVC tube. The problem was finding a mold that wasn’t too expensive. I didn’t want to spend over $10 on the mold.
So, I was in Lowes picking up some supplies and thought I could build one. Something simple (with no dowels or anything). I went by the lumber section and found what I needed. Got my dad to teach me how to use his table saw so I could cut the pieces. Then it was a simple matter of some sanding to smooth the edges and then gluing and stapling and I had $10 molds!
I got 1/4″ wood for the bottom base. Then 1/2″ for the “anchor” base. Glued it in place and then just built a box that slid over the anchor base.
You can see that these are much bigger than the standard 2lb/3lb soap molds.
The dimensions for my mold are:
Width: 3.5″ Height/Depth: 2.625″ Length: 11″ –> Volume wise that gives me 101 cubic inches (approx. 56 ounces).
The dimensions for the silicon mold are:
Width: 3.5″ Height/Depth: 2.25″ Length: 8″ –> Volume wise that gives me 63 cubic inches (approx. 34 ounces).
(Hopefully I did my math right!)
So you can see mine holds significantly more. I’m going to have to play around with the size bars I get for a 1.5lb batch, 2lb batch, 2.5lb batch. I think if I were making this and wanted to get the same dimension bars as I get from my 5lb mold I’d have to use about 3lb of soap…some experimenting will follow.
What I learned from this is that I can make a simple mold (cost effectively) this way. Next time I’ll by the longer wood and then cut them up to be closer in size to the silicon mold for my classes.
