I started working on our portable foot bath today. So far, these are our expenses:
40 mil shower pan liner - (2) 15' x 4' sections - $153.30
Pan adhesive - $7.86
Wood screws - $8.69
I'm using true-dimension 1x4 douglas fir that I milled - I guess there's a cost to it (my labor), but I won't include it for these purposes.
Today, I constructed a gate frame for the back of the trailer. This panel is removable in case we want to use the trailer for other purposes. I'll cut two 18" x 48" sheets of plywood to use as gates - these will be guillotine-style gates that slide up and down. I'll also need to build two short panels that will run from the end of our alley to the trailer (for loading the sheep into the foot bath). I also need to glue the pvc liner together and put it on the floor of the trailer.
