I am not sure if this link will work, but last year I built a hand held zamboni that I use to flood my pond. It is made out of 3/4" copper and connects to a garden hose. It takes me about 45 minutes to do 1/3 acre. It does scare the crap out of me though cause when you are putting water on a frozen surface boy do you get some very loud cracking noises! Anyhow here is the link. Ice Flooding Tool

Its not how well you do something,
Its how well you look doing it!
