Hi Megman, Good to know that you are still among us. Are you taking official "physical therapy" ? I bet you know what to do for those muscles and ligaments and are doing it. Oh, I have sympathy pains for you!
Not taking anything officially yet. OHIP no longer covers it so I'm still shopping around for something on the cheaper side.
I am pretty familiar with what needs to be done, but being on it for 9-10 hrs at a time is not helping to say the least.....

Wanna ride the Zamboni?
I'm walking with my foot straighter now as opposed to sideways. Using the ankle more and the calf muscle is just screaming. The knee and quad are not happy either, but it's getting better.

How does a zamboni work? I assume it is cooling the water before laying it down? How much water does it carry? How much water does it take to do a full tour of a normal rink? Where does runoff water go (do you lose ice from sublimation or does it melt and runoff?)?
The heartbreaking necessity of lying about reality and the heartbreaking impossibility of lying about it.

Short answer: First a sharp blade shaves off about 1/16" of ice. The augers (blue in the video)take this snow to the snow tank. Then it is flooded with cold wash water which is collect via a squeegee and returned to the wash water tank. This is green in the vid. Then the ice is flooded with water that is between 140-160F (silver in the vid). We use flood water this hot for 2 reasons: It makes much denser ice as it has less oxygen than cold water and it gives us much clearer ice for the same reason, which in turn allows the color of the lines and logos to come through.
Tank capacity varies from Zamboni to Olympia, but there is roughly 60 gallons of cold wash water and 200 gallons of hot flood water.
A good driver can flood a 200' X 90' ice with as little as 50 gallons in 8 minutes.
As for runoff, we have none. The ice dam keeps the pad in place and the concept when doing a flood is to take off what you put on in order to keep the ice a consistent thickness.

fascinating. I have seen them all my life and did not think they could be heating the water instead of cooling it. Also, heated water cools faster than cold water doesn't it? Lots of misconceptions about this stuff.
Thanks!

Oh no no no. We fill the flood tank with hot water. The Zamboni doesn't heat it up.
