Building the Atkinson Differential Engine by Vincent R.Gingery

Building the Atkinson Differential Engine by Vincent R.Gingery

David J. Gingery Publishing| 2000 | ISBN: 1878087231 | Pages: 112 | PDF | 30.25 MB

After a year of constant work, the differential engine book is finally ready. It's been so long since I heard from Vince, I thought he was deceased, deranged, demented or all of the above. But it was worth the wait.

You learn not only how to build this particular engine, but you learn the general skills that can be applied to all engines: patternmaking, molding, casting, boring, lapping, and all the rest.

Contents include: building a wooden mockup, casting, patternmaking, side panel pattern, side panel molding procedure, front & rear panels, oscillating arm patterns, piston rod pattern, preparing the base, assembling the main frame, boring crankshaft bearings and arm pivots, the ignition plate, the water jack assembly, making a copper lap, milling the cylinder ends, mounting valves on the cylinder, the electrical system, and much more.

This 1886 engine predates the Atkinson Cycle engine. The front panel is about 8" tall. A pair of 1-1/8" bore by 2-1/4" stroke pistons drive a 8-3/4" diameter flywheel. The arms of this engine move the two pistons toward one another in such a way as to compress and ignite the fuel charge so that all four strokes are completed in one revolution of the flywheel. The action looks like a street corner con man running a shell game!

Loaded with drawings, photos, specs, and wall-to-wall detailed how-to. More of the usual quality that always come out of Gingery Publications.

From the backcover...

Even before James Atkinson developed his unorthodox "cycle" engine, he developed this totally unconventional "differential" engine in an attempt to circumvent Nicolaus Otto's patents on the four-stroke engine, and to allow Atkinson to compete with Otto headon in the new gas engine market.

Here, you get detailed plans based on Atkinson's original patent that will allow you to create a working version of this most unusual engine. Numerous prototypes were built in the process of developing this book. The secrets learned will allow you to sidestep potential bottlenecks, and the learn the hidden details Atkinson chose not to reveal in his patent.

Even if you are not likely to build this engine anytime soon, by studying the contruction secrets revealed here, you can journey back in time and taste the state of the IC engine art as it was in the 1880's. Discover how this amazing engine was able to complete all four strokes in a single revolution of the crank without the aid of timing gears or separate cam shaft.

If you have built, or at the very least, have studied our earlier book on the Atkinson "Cycle" engine, then you already know what an amazing engineer (in the truest sense of the word) Atkinson was. Here, you'll find the ge action and peculiar differential motion of the two pistons working together in the same cylinder to be hypnotic. If you thought the "Cycle" engine was unique, "then you ain't seen nothin' yet!"

You get step-by-step instructions from Vince and Dave Gingery showing how the Atkinson "Differential" engine is built from original patent drawings. A lathe, a milling machine or milling attachment, and other commons tools are required. Castings are suggested for the main frame, oscillating arms and flywheel, but none of these parts are so complex that they could not be made from stock material. Other parts such as piston rings are readily available from the suppliers listed. But if you want to make your own piston rings, we'll show you how to do that, too.

An Atkinson "Differential" engine is a machine you'll be proud to have built. And we think you'll find as we have, that this engine is an essential component in understanding the genius that was James Atkinson.

Few people have seen the differential. When you start it up, and tell them that you built it, your friends will be amazed. They will swear it's magic.

Build a differential engine! Start today!

How to Build Pipe Bending Machine by Vincent R.Gingery

How to Build Pipe Bending Machine by Vincent R.Gingery

David J. Gingery Publishing | 1998 | ISBN: 1878087215 | Pages: 48 | PDF | 6.47 MB

Bend pipe and make bedframes, chairs, handrails, and just about anything else your twisted imagination can cook up. This easy-to-build and inexpensive machine will bend up to 1" diameter pipe using hardwood dies. Need something bigger? Scale it up, make the lever arm longer, and buy a gorilla. (Your mother-in-law won't do. She may be just as ugly, but not as strong...)

Vince will show you how to build this very simple machine that allows you to bend pipe from zero to 180 degrees. And with appropriate dies you can bend solid round rod, flat bar, and square tubing as well. The whole thing is built from 1/4" x 2" hot rolled steel strap. Other than a drill press and welder (just a few beads needed) only common handtools are necessary. Get a copy of this inexpensive book and build this inexpensive project. Gee... You could even learn to bend electrical conduit and get rid of those 38 extension cords running all over your shop! Build a rack, and torture your inlaws! The possibilities are endless.

The Secrets of Building a Plastic Vacuum Forming Machine by Vincent R.Gingery

The Secrets of Building a Plastic Vacuum Forming Machine by Vincent R.Gingery

David J. Gingery Publishing | 1999 | ISBN: 1878087223 | Pages: 106 | PDF | 21.88 MB

Geez... you should see the samples of vacuum forming Vince sent me! I can show you a photo but until you hold the formed sheet in your hand you don't know how powerful this thing is. It's professional quality. And you can build it for far less than you can buy a machine.

And since Vince will reveal his experiences, you should be able to adapt the design and scale it up or down.

The best way to describe the machine is to let Vince do the talking:

"The machine is built almost entirely of angle iron and flat bar. Construction is simple, with some welding being required. Being built on wheels makes the machine easy to move from place to place. It has a unique clamp frame that works very well and the adjustable work surface (platen) is a real asset. The machine has a 12" x 15" forming area, and I have formed ABS plastic up to 3/16" thick with it. I believe the machine would form 1/4" as well. Of course, thicker plastic takes longer to reach forming temperature.

The machine operates on a 20 amp 120 volt circuit using a 1500 watt, 120 volt heating element. Temperature is controlled by an infinite range switch mounted in the control panel. Everything required to build the machine is easy to find except for the 120 volt heating element. It's an oven replacement element, and ... will sell for around $30.00 plus shipping...

The vacuum for the machine can be supplied by either an air venturi pump or electric vacuum pump in conjunction with two storage tanks. I am mentioning the air venturi pump as one alternative because it's so cheap. Only $12.99 through Harbor Freight and it pulls 4.2 cfm per minute taking about 4 minutes to pull a 25 hg vacuum on my two 11 gallon tanks. Not too shabby for the price. In order to use it though, you need to have an air compressor capable of maintaining 90 psi.. The other and better alternative is an electric vacuum pump. The electric pump I have pulls 6 cfm taking about 2 minutes to pull a 25 hg vacuum. Although twice as fast, the electric pump costs close to $300.00."

You oughta have a copy of this... for your reference library if nothing else.

Plastic Injection Molding Attachment for a Drill Press by Vincent R.Gingery

Plastic Injection Molding Attachment for a Drill Press by Vincent R.Gingery

David J. Gingery Publishing | 2007 | ISBN: 1878087312 | Pages: 48 | PDF | 10.30 MB

Build this simple, but effective attachment and start shooting plastic. A little more than an ounce of plastic doesn't sound like much, but that's a substantial volume that can be used to make many kinds mechanical components, parts for models, and (knowing you) obscene sculptures.

You'll get a material list, drawings and details on making the support posts, the nozzle, the injection cylinder sub-assembly, the ram, and the ram sub-assembly. You'll be shown how to wire up the controls, how molds are made, how to identify recyclable plastics, use the temperature controller, and start injection molding.

You get the usual Gingery quality: photos, drawings, detailed text, suppliers, hints and tips, and all the rest that has made Gingery Publishing world famous (and that is no exaggeration)!

You oughta have copy. Sorry, no details on using this versatile device to make chewing gum, worm capsules for your dog, or exploding suppositories for your mother-in-law. But, geez... you oughta come up something more original than that, anyway.

Vince Explains...

"For the most part, plastic injection molding today is done with complex automated machinery turning out many thousands of items per day. But what if you are an experimenter, inventor or hobbyist and you just want a few parts made?

We have attempted to answer that question for you by providing these plans for a small hobby size injection molding machine capable of molding slightly more than 1/2 ounce of plastic. (.59 ounce to be exact)

This amazingly compact machine is designed to be used with a floor model style drill press having a minimum spindle travel of 3". Thus, we refer to it as an injection molding attachment for a drill press.

The unit itself measures approximately 12" long x 1-3/4" diameter at its widest point and weighs just 3 pounds. In operation, plastic is melted in the injection barrel of the machine by two 1/4" diameter x 2-1/2" long cartridge heaters. The temperature of the barrel is accurately controlled by a digital temperature controller and thermocouple arrangement. The force required to inject the plastic is provided by the feed mechanism of a drill press. Construction is simple and straight forward, but it will require basic metal working knowledge and the ability to operate a metal lathe and a drill press along with other hand and power tools associated with metal working and machine work in general. Here in this booklet you will receive detailed step by step instructions along with photos and drawings showing how to build your very own injection molding attachment for a drill press...."

Uncle Dave Gingery's Shop Notebook by Vincent R.Gingery

Uncle Dave Gingery's Shop Notebook by Vincent R.GingeryDavid J. Gingery Publishing | 2005 | ISBN: 1878087258 | Pages: 56 | PDF | 11.58 MBClustering is one of the most fundamental and essential data analysis techniques. Clustering can be used as an independent data mining task to discern intrinsic characteristics of data, or as a preprocessing step with the clustering results then used for classification, correlation analysis, or anomaly detection. Kogan and his co-editors have put together recent advances in clustering large and high-dimension data. Their volume addresses new topics and methods which are central to modern data analysis, with particular emphasis on linear algebra tools, opimization methods and statistical techniques. The contributions, written by leading researchers from both academia and industry, cover theoretical basics as well as application and evaluation of algorithms, and thus provide an excellent state-of-the-art overview. The level of detail, the breadth of coverage, and the comprehensive bibliography make this book a perfect fit for researchers and graduate students in data mining and in many other important related application areas.Reupload: Since all Gingery series ebook on Avaxhome none are activeDLrapidshare

Working Sheet Metal by David J.Gingery

Working Sheet Metal by David J.GingeryDavid J. Gingery Publishing | 1993 | ISBN: 1878087134 | Pages: 90 | PDF | 17.83 MBLet Dave Gingery get you started in working sheet metal with a hammer, a tree stump and a simple bar clamp you can attach to the front edge of your workbench. He'll show you all the basic joints and edges, and how to make them without fancy machines. He'll even show you how to make a gas tank. This is not the ultimate sheet metal book, just the straight scoop on how to get great results with simple tools from someone who has done it. Consider this carefully!Dave Gingery Explains His Book...This book was inspired when someone gave a friend of mine a furnace. Local sheet-metal people all wanted $1000 or more to install it. My friend is almost as stingy and tight-fisted as you and I so he didn't go that route. Instead, I picked up a couple of sheets of galvanized metal, a couple of joints of prefab duct and fist full of "S" slips and drives and we did the job in a half day for less than $75.00. ...We didn't have any of the fancy equipment for the job but we did it any way. That's what this book is about.No photos of exotic equipment in these pages. And no instruction in using press-brakes, leaf brakes, slip-rolls, bar-folders, turning machines, edgers, crimpers, lock-formers or any of the commercially built equipment found in commercial shops... Instead, this book shows you how to do the work without machines.Sheet metal work was my second trade and I worked it for years... So here I am showing how to produce what you need without the machines, and there is hardly a limit to what can be made.The chapter on layout is brief but it covers all the basics. It would be no trouble at all to write 500 pages on pattern problems and examples alone. But that has been done very well by many [others] in the past. My message is that the principles are few and simple.Reupload: Since all Gingery series ebook on Avaxhome none are activeDLrapidshare

Designing and Building Sheetmetal Brake by David J. Gingery

Designing and Building Sheetmetal Brake by David J. GingeryDavid J. Gingery Publishing | 1980 | ISBN: 1878087061 | Pages: 52 | PDF | 8.05 MBVery Do-able project! Do this D.G. project first, July 11, 2003By T. Burtell "Book Burner" (Dearborn, MI United States)Well, I'm almost done with my brake (only the clamp ge needs to be attached). If you do any of the Gingery projects you should start with this one.Here's why: Only basic layout skills required, Useful project when done, Relativly fast to build. Takes about 1 - 2 weeks to complete (2-4 hrs a day) for a novice like meI bought the Slip Roll Machine book and got stuck on the third part. Squared-off interior holes are hard to make without a square broach. That's totally bogus to weaken the part with an entrance point for a vertical bandsaw. (And makes for even non-technical people around the shop question your abilities as a machine builder). Anyway, the sheet metal brake book doesn't ask you to perform such hacked-up methods, and so is better.Here are some of the drawbacks of the book:1. The picture on the cover isn't quite the same as the project inside ( no little stops attached to the clamp grip, and the hand-levers are not rounded as he shows in the drawings) 2. He says weld top and bottom of the base leaf where it meets the pivot bracket (If you follow his advice you will destroy the 1/4 - 20 hole in your path!) I welded a fat bead on the bottom only, and this is just fine. This won't mean anything to you unless you are building the project. 3. It would have been better for him to dimension a drawing from only two edges, not four. Thus, all your holes will be correctly distanced in relation to one-another, even if your hacksaw cuts are a bit off. Anyway, you can still do a little shop math to make-up for this. Being a beginner, it would have simplified things. 4. He oddly says that the reader most-likely doesn't have a metal-shop at his house (which is true), yet this is book 7 out of his metal-shop from scratch series!Overall, excellent book. Very fun project. When you file and then sandpaper off the file marks from the pivot bracket, you can get a part that looks so good it looks store-bought. That's pretty cool. I didn't have the exact steel stock on hand and was still able to build it.What really counts here is: Does this brake work when you're done? The answer is yes!Reupload: Since all Gingery series ebook on Avaxhome none are activeDLrapidshare

The Dividing Head & Deluxe Accessories by David J.Gingery

The Dividing Head & Deluxe Accessories by David J.Gingery

David J. Gingery Publishing | 1982 | ISBN: 1878087053 | Pages: 160 | PDF | 33.62 MB

The main object of this manual is to provide the means to produce spur gears so that we can add change gears to the lathe. While we can hardly expect to produce a perfect involute gear tooth in the home shop, we can certainly make a set of change gears for the lathe that will mesh nicely and provide the accurate and positive drive to the lead screw that is needed for cutting screw threads on the lathe. The work is much easier than you may have imagined, and the cost is so slight that it just doesn't make sense to deny yourself the advantage of this improvement to your shop.

Few of us could bear the expense of a set of formed gear tooth cutters for the miller, but it is an easy job to grind a simple fly cutter at a cost of about half a dollar. Mine has cut something over 200 gear teeth with no sign of blunting. The gears are uniform and mesh nicely with each other and with commercially made gears. There would be no problem in gathering enough data to write an entire volume on gear technology alone, but most of the information would be of little value in the home shop. Don't be concerned with the inability to produce a perfect involute gear form because such a thing hardly exists except in theory. Modern equipment can come very close to perfection but they still miss by a little bit. You can come so close with these simple methods that only an expert with very exotic equipment could find the error.

A worm wheel dividing head is a simple and fascinating device. It is the only practical way to provide a broad range of dividing capability to the shop, and its versatility will amaze you. It not only enables you to make accurate gears, but it will handle any other dividing or indexing chore that you may assign to it. Its accuracy will be more than adequate for the broad and general class of work, and you will have a piece of equipment that most home shop operators must do without. If you have completed any of the earlier projects in the series you won't find these projects difficult. The first chapter is largely a review of simple methods and devices from earlier manuals, and these provide what is required to build the dividing head and add change gears to the lathe. The castings that are required are all within the one quart capacity of the charcoal foundry, and the simple methods for producing the castings have been well covered in the earlier manuals. Most of our discussion will be on finishing and fitting the parts.

The Drill Press by David J.Gingery

The Drill Press by David J.Gingery

David J. Gingery Publishing | 1982 | ISBN: 1878087045 | Pages: 128 | PDF | 26.25 MB

Built entirely of home-made castings and standard hardware items, this drill press will make a valuable addition to your shop. It drills to the center of a 12" circle with a quill feed of 2 1/2". Both its spindle and countershaft are mounted in ball bearings. A single lever belt tension mechanism changes speeds quickly. A low speed of 260 RPM enables you to drill 5/8" holes in steel. Its table is adjustable radially for angular drilling. Quill feed is by cable winch or roller chain so there are no racks or pinions to make or purchase.

The machine is carefully planned and designed with the home built 7" swing lathe in mind. All of the castings are within the one quart pot capacity of the charcoal fondry. There is still no need to have any work done at the local machine shop and still no need to purchase any expensive tooling or accessories.

Though building a drill press may be the most difficult project in the series to justify, considering that a very serviceable imported machine can be purchased very cheaply, these operations have great training value as you build your shop and develop your skill. It is very likely that you will value the experience far more than the machine. It will certainly repay you for your labor and patience as you use it for some of the exacting jobs still left to face as you finish building your shop.
