Mixing + Pouring Concrete
This is a very detailed build, and I really like it but the cost is in another bracket. I have seen several of these and none have cast as much to build! So maybe someone could share material substitutes that are less expensive but are equal or greater in strengh.
Yup! There is a pressure relief valve in the system that protects the compressor. To high or to low and the system will shut off.
You need a gauge to tell when your system is at proper charge. It will prevent you from over charging or not charging enough. Under charging will leave you where you when you started, Not cooling, over charging will add stress to your compressor and cause premature wear. There should be a chart in the package to give you, at least an idea of how much to charge.
Adding Refrigerant to a vehicle does not require a draw down (or evacuation) of the system. However if the system has a leak and has been repaired or if it has been open at some point then yes an evacuation definitely would be required and would best be taken to an A.C. mechanic, this is not for the untrained.
It occurred to me that using a meat grinder would be a good way to press the liquid out of the beets and repeating would allow you to save even more.Using a sieve to catch the solids would save a lot of work.I always use one when making Jellies.
Black PVC is also very large and is certainly Not conducive for the stated purpose. Schedule 40 PVC 3/4" or 1" painted black is a good choice as it will allow a good flow of water still allow it to have time to heat depending on the length of the pipe. Using multiple U shapes will allow the water the best amount of time to heat. Hope this helps.
If you are worried about too much heat use CPVC which is designed for hot water but it is also a smaller inside diameter.

This is one I will have to try but on a regular bed so my dimensions will be different. I will just adapt to a smaller scale. I love the concept because I am an older person and the night lite sensor Idea will greatly benefit me.Thanks for a great "ible".

I notice this was posted a year ago yet I must ask a current and on going question????. The "dunks" used, are they harmful to bees? I am a beekeeper and most chemicals are not safe for use around my beehives. How about some of you chemical "experts" weighting in on the subject.
