Aw, Paul, you really do need a cow! And a milk machine to go with that gleaming ss can!
Funny thing is, about 6 months ago, I sold the ss can I had - it held about 7 gallons and I couldn't imagine being able to carry it even half full because it was so heavy empty. Just a couple of weeks ago, I was given a Delaval milking system. The can probably only holds about 4 gallons, so much more my speed.
It is at the repair shop now and we will see if the pump is operational. If not, I do have a source for a pump for about $500 plus shipping, so I'll be saving up my pennies.
