Here are some pics from my second test run. Sorry about the quality but all I had was an old quickcam.
First pic is one of my pump. All the white is frost and ice. I don't think this pump can handle these temps so I will need to replace it. The colder is gets the stranger the noises get.
Here is a pic of Garys #2 chiller. Check out the ice on the tubing.
Here is a pic of the blocks after about an hour. They are danger den blocks and shouldn't be white :twisted:
Now here are some pics of the thermometer after about 1.5 hours. Once I put the insulation on the tubing it should get much colder! Its a cheap thermometer so I don't know how accurate it is.
