The gas powered refrigeration is based on an "absorption cycle" (a thermodynamic term). In an absorption cycle, a secondary fluid, the absorbent, is used to absorb the primary fluid, the refrigerant,

Sorry about my technical response. How about this: To produce a cooling effect, you must "move" heat from a heat source to another heat source. In your home, your AC moves heat from the inside and "r

Beware of having the machine shop "mike" your crank unless you trust their work. I moved to a new city, did not know of any good shops, and had a crank "miked" at the local machine shop. They said th

When I said "bore gauge," I did not mean "snap gauge" or "T-gauges." I would love to have the type with the dial gauge. This measures out-of-round. But to get a "quality" gauge of this type that meas

My experience as an engineer is most people resist change and refuse to embrace new technology. "The old goggles work, so why change?" "Bubba" can take his $25(?) helmet, flip it down, and start weld

I once knew the manager of the tool department of a Sears. Any Craftsman tool that carries the "lifetime warranty" can be replaced for free at any time for any reason. The next time you are in a Sear

Sears will only replace a lifetime warranted tool with an identical tool. They will not give a cash refund! Never heard of this. I once told them I had already bought a comparable tool from another s

Amen, I couldn't have said it better myself! I'll ring in... Nothing that runs on 220 is portable, IMHO, because there seems to be very little standardization on 220 outlet configurations. Wherever y

Do yourself a favor. Go ahead and get a MIG. For under $500, there are several nice home MIG welders on the market. You will appreciate the superior weld quality of the MIG. Besides, how much money a

There are a lot of welders on the market sold as "MIG" that use a flux covered wire. These are sold as "gasless MIG" welders. Actually, if anyone wants to get technical, the "MIG" welding process is

I have a 4" side grinder I purchased from Sears 7 years ago and it is still going strong. I know Sears quality is not what it once was, but I am amazed that little grinder still works as well as the
