RapMan RepRap or “RapMan” (as it is commonly known among the 3-D world) is a 3-D printer. A 3-D Printer (as I like to call it) is basically a “CNC (Computer Pneumatic Control) hot glue gun” because it extrudes plastic (like a hot glue gun) in specific places based on computer control. Now lets get down to basics, 3-D as it is in the dictionary means: having, or seeming to have, the dimension of depth as well as width and height. Therefore sense a printer is something that produces, a 3-D printer is something that produces an object with three detentions of measurement (width, depth, and height) for example a mug, or cup, or bowl, etc. So now that we are on the same page, let’s talk more about the printer itself. It has a print bed that moves up and down to give you your dimension of height. It also has a carriage that has interchangeable heads that can move back and forth and side to side to give you your dimensions of depth and width. Then you have your print head which extrudes the plastic that is fed to it in a wire like string from a giant spool at the side of the machine. The string is fed into a heater barrel, which is a tube that gets hot enough to melt the plastic and force the molten plastic through a small nozzle and onto the print bed. Then there is the IC or integrated circuit that is the brains/computer of the 3-D printer, it controls the head movements, bed movements, heater temp, extrusion rate, and, well, basically the entire machine. My name is David Baker and I bought my RapMan at Bits From Bytes (see link below) for about ₤ or about $ it is pricey, but well worth the investment. If you should buy one please mention my name, David Baker, for I will get a cut for marketing. That is the basic machine, for more information, please visit the following web sites our contact me through the contact page at my web site (the last web site below).

Millie Millie is a steam engine that is a little bigger than a quarter. She is a great project for newbie's to the industry of machine shops. I made one out of steel and brass stock. She can be found and is featured in “Table Top Machining” by Joe Marten.
Jensen Steam Engine The Jensen Steam Engine is an oscillating steam engine manufactured by Jensen corporation Jeannette, Pa. It comes as a kit and can be assembled easily.
Hero’s Fountain Hero’s Fountain is a fountain that uses a upper B and lower C sealed reservoir with a half a reservoir A over the upper B sealed one. You fill the upper sealed reservoir B with water, then you pour water into the half reservoir A where it flows down through a tube into the lower sealed reservoir C. The water pushes up on the air in lower reservoir C, forcing the air to flow through a tube into upper reservoir B. The air pressure in the upper reservoir B pushes down on the water, forcing it to flow up a tube and through a nozzle up into the air and back into the half reservoir A, repeating the previous actions.
