Thought about a length of 10" or 12" PVC split in half to make a trough. A four foot
long half section would hold about eight or ten gallons but the stuff runs anywhere
from $25-$75 a foot and a cap for the end is in the hundreds of dollars.
So…………that’s out.

An ag dealer huh. Got lots of them out where I'm at half way between the lake and
the river. Looks like I might have to end up with some kind of trough like that after
all if I want to get this done. The only problem I see with that is it would be kind of
a temporary set up which I'd have to empty out a soon as I'm finished. I was sure
hoping to find something that was a little more sturdy or permanent with a fairly
tight cover that I could store the liquid in from one use to the next. That’s what I'm
doing now with the Rubbermaid storage containers that I've been using.
Well, I'm off to search the net for some info on "silage bag film", wonder how it
would hold up to phosphoric acid?????

Thanks for the ideas guys, been awake half the night hoping for an epiphany like I
had the other night. I’ve been hearing for years all the horror stories of days spent
taking the rivets out of the grills. I woke up in the middle of the night last week and
had my answer. I had this picture in my mind of those vise-grip pliers to hold a drill
bushing on center while drilling the rivets out of the grill. They worked great, I took
the whole grill apart in less than two hours (with several interruptions at that) and
didn't damage one of the original holes.
I’ve all ready talked to a machine shop about making a short run of the special hardened
drill bushings that holds the drill on the center of the rivet head and I‘m gonna search for
quantity prices for the vise-grips this week. I think anyone that’s tried to balance a drill bit
on four dozen spinning tubular rivet heads would be glad to have a pair of them in their tool box.

So, back on track for my orthophosphoric acid tubs.
