You could use the tea light tin as a mold to cast a lead flywheel. After searching around my house for a suitable container to wrap the copper heat exchanger pipes around I finally stumbled upon an old body spray can. Tip - Use gloves when working with the metal sheetwhile the edges may not feel sharp a small slip of the hand can yield some pretty massive slicesonce again speaking from experience. PART 1 - building a miniature boiler. As watertube boilers do not enclose large volumes of water, their inherent risk is less than firetube boilers. She has conducted survey work for marine spatial planning projects in the Caribbean and provided research support as a graduate fellow for the Sustainable Fisheries Group. This instructable does not include instructions on how to build a boiler to produce steam. Since it was nearly empty I depressed the trigger to clear out as much of the compressed gas as possible then using a small drill I made 2 holes in the top of the can to release any remaining pressure and allow for a way to flush out the rest of the contents. The height will vary depending on your method of heating (tea light candles, container of liquid fuelwood fire box???). Rockmart GA 30153, Boilers vs. This vessel contains a set of tubes and two other parts, one for combustion and another to contain water. Replace the Pressure Weight The other thing your pressure cooker should have on it is a weight of some kind to let steam out during the cooking process. I am a very visual teacher so be sure to read the 'Image Notes' (hover your mouse over the yellow boxes on the images), it will likely make my instructions clearer. Turn on the air and give the flywheel a quick flick and the motor should start, if not try flicking it in the other direction. Finally Drill the bottom hole the same size as the plastic tube from your Q-Tip. When the water heats, these solids foam from the steam. Next make sure that you did not accidentally get glue in any of the holes that supply air to the motor. Try filling a section of copper pipe with water and seal it on both end and place it in a freezer. This is an instructable for my small sized steam boiler.

They are suitable for use in smaller-scale buildings and facilities that do not require a large amount of steam power. Steam boilers are used for a wide variety of residential, commercial, and industrial applications. I built this engine in one day and for under $10 in materials so I think it's safe to call it a success. I used a spring from a retractable pen held in place with a screw on "prop-saver" from a model airplane. This motor works quite well for me on ~15psi. To make the flywheel I popped the wax out of a tea light (candle), inserted the crankshaft wire through a few pieces of wood to keep it from pulling out of the wax and glued them to the crankshaft, then I added some metal washers (to add weight). To make the motion of the piston easier to see, you might want to attach a small paper "flag" to the top. After soldering the boiler body is complete. If you do this you should probably make the crankshaft wire a cm or so longer. It is then led and soldered to the boiler with the cut end in contact with the boiler and the thread facing upwards. I've learned a lot from the many users of this community and thank all contributers for ideas and insight. Recipe Shaped Crafting Usage The boiler accepts the following items as fuel: The boiler has a minimum temperature of 20 and a maximum temperature of 500. Like the larger box, it has dowels through the center to support the workpiece. Boiler efficiency improves by optimizing the way boilers are used. l follow your nice tuto, and l even posted a video here: but l didn"t want to buy anything, especially brass tubing, as l found an aspirin plastic tube just in the bin. on Introduction. The pressure of the steam trying to escape, moves the rotating assembly of the engine. Once again all joints must be air tight so take your time and do a clean job. 2 silver solder for the entire boiler including stays. As you can see I cut this panel with my cnc mill, I also cut the lettering with the mill as well. I used a short section of copper tube which fits VERY snuggly inside the airplane fuel tubing. As mentioned earlier, the two main types of boilers you will find on the market today are firetube boilers and watertube boilers. To do this I just glued some plastic tubing to the body; just do whatever works best for you. The safest modern boilers virtually eliminate the possibility of catastrophic failure, creating a much safer work environment. To cut the round crankshaft part start with an octagon shaped piece and sand the edges to a circle.Body: Now start by gluing the part Body 2 to Body 1. The Small Coal Boiler is a steam generator added by GregTech 5. if I double the measurements and make the project bigger,will there be any problem? Then, slide the copper tubing through 2 holes in the can, place it in a bowl of water, and bend the ends so they are submerged. I toyed with the idea of machining a nice channel for the valve to rest in with my CNC machine (also homemade) but came to the conclusion that not all people have a CNC machine in their apartment :) . Boiler horsepower is used for sizing steam boilers. I used a sanding drum to de-burr the holes on the inside to ready the housing for the boiler installation. Add more Q-Tip washers on the piston side to provide proper spacing so the face of the wooden crankshaft part will be under the center of this piston. Each boiler is given a boiler horsepower (BHP) rating based on the steam output capacity at 212F and 0 psig. Note - If your interested in the CNC machine you can find my build thread (with DXF drawings of this machine) over here:
