The liquid gas is warmed by ambient air and the injected fluid. In the process of going from a liquid to a gas in the plumbing system and cylinder the gas expands almost 800%. It's more efficient than current electric cars. This system also eliminates the problems electric cars have. Liquid air...

You beat me to it. The only difficulty you might have is the angle of the hand wheels and reaching over spinning work and chuck.

Just found this and thought it might be interesting to all here. Dearman Engine Company

While you're at it you can make several soft jaw sets with milled steps so you don't need parallels. Also make some with V's milled on the face so you can hold round stock as well.

Linux comes with Apples CUPS printer support system which is also used on Macs. Most people don't know that OS-X uses a modified Linux Kernel. That's the reason Linux distributions appear to have copied the look and feel of Apple/Mac computers. In reality when Apple started using their version...

Another reason not to do that is the inability to shut it off in an emergency. You could get your clothing hung up in the lead screw or feed shaft and be unable to shut it off before serious injury occurs.

The trick is never allowing the tool to turn any colour while you are grinding it. Grind a moment and then plunge cool it in water. Don't get in a hurry and take it slow and easy. If you do give it some colour while you are grinding it you'll need to grind that colour away as that coloured metal...

Buy a Bridgeport and be done with upgrades.

If a lathe or any machine tool is going to sit for months without use the ways should be protected with something other than a thin coating of oil. Needless to say cosmoline would be the best choice until you need to use the machine again. Instead of coating rust prone areas to prevent...

I think humans have gone through more "Dark Ages" than we know. We advance technology to a point where we end up destroying ourselves with it. Consider the discovery of an ancient city beneath the Cambodian jungle. When you consider thousands of people living in that vast city their level of...

99.8% zinc ingots are available from Rotometals. They have babbitt, bismuth, and other alloys too. http://www.rotometals.com/product-p/zincingots.htm

I would put a string of LED's on it and forgo the resistors and voltage regulator. You might not realize that you are building the electrical equivalent of a bicycle wheel hub dynamo. You can use simple electronic circuits once you figure out the current/voltage output of your dynamo once you...

You can cut a hole in the floor, frame in a form, and pour a pad. You can get away with pouring the concrete directly on top of the ground. Someone might hate that you did that 30 years from now IF they keep the building and the Mill. If it shifts while you still own it you will just need to...

Before you purchase a vintage machine you might want to consider a new or later model machine with dual ASE and Metric dials and change gears that allow cutting metric threads. When I purchased my lathe back in 1985 the salesman wanted me to buy one of the in-stock lathes without Metric dials...

I would love to have a Bridgeport mill. Currently I have a LuxMill I acquired in 1985. This mill is still available under many OEM names such as the Grizzly G0730. I consider it just barely adequate in size. As a matter of fact I made a head spacer that increases the maximum distance between the...
