It sounds like a lot of work, but it really is very simple, and as I said earlier, the average cost per perch is 50 cents. The hardest part is cutting the seams and waiting for the cement to cure. Good luck!
You don't need to hold the molds in a 2x4 with holes drilled in it......that's just how I do it because I make a lot of them. ANY method that you can hold each individual mold straight up during and after pouring, is fine.
The 2x4 I use is about 18" long and holds about 20 molds. The holes were drilled using wood bit, and are spaced about 1" apart. This is a little larger than the outside diameter of the PVC pipe.....that way, once you've got the bottom and seam of each mold taped up, you can place the PVC mold into the 2x4 and pour your cement. A lot of people don't have this kind of wood bit, so a tin can could be used to stand the molds straight up in, instead. But the 2x4 is definitely the EASIEST way to hold the molds straight. Of course, if you want to make your perches a little wider in diameter, your holes in the 2x4 would also need to be the appropriate size.
Cement, does not have rocks, but is a free-flowing powder. Mortar is a mixture of cement, sand, lime, and water. Concrete is a mixture of gravel and cement (or mortar). I call my perches cement, even though technically they're mortar. (Most people don't know what mortar is). I use a ratio of 3 parts sand to 1 part cement, but if your hubby would feel better, let him go 2 to 1 ratio. When I first started making these, I used straight cement (no sand) and water. It took longer to set up and the finished product was too smooth, even after sanding. The reason these perches take so long to set up, is because there is no air flow inside the mold, and the mixture is surrounded by a non-porous surface. I let mine set up for AT LEAST 1 week. If you don't do this, your perches will fall apart when you remove them from the molds. These perches, ONCE hard, are not toxic.
