If It Works."One Way To Make A Garage"

Here is a little book by a homesteading couple, who's attitude and methods I can aspire to. Working people, with out deep pockets, they wanted a farm and were willing to do the hard work to get it and more hard work and ingenuity to build it up to a working farm. The "Foreword" says it best.

"Working Wood" by Mike and Nancy Bubel was written in 1977 and published by Rodale Press. In this book Mike and Nancy document many of the projects involved in the building up of a working farm. Mike is a hands on diy kind of guy, he has many innovative ideas, tips and tricks for building all the requirements of the small farm. One of the projects a large barn was completely built from recycled materials. As Nancy says you will not find fine furniture here  but you will find sound projects for building up a comfortable country property inexpensively.

Following is a project from Part II "One Way To Make A Garage". This is a quick and inexpensive way to build a garage shelter, it would also do as a material storage shed, small foundry, small forge, protected from the weather yet still well ventilated. I have a number of cordwood construction manuals and have considered building one of those structures for some of the mentioned purposes. This idea is quicker, less expensive and more suitable for the above purposes. Mike uses an asphalt roof. A 1 X 4 strapping grid on the 2 X 6 rafters, covered with metal or fiberglass roofing panels would also work well for the roof. I have some large old willows on my property and I have to agree with Mike, it's pretty useless as a heating wood. This may be a good use for them the next time I need storage space.

Electromagnetic Repulsion Coil

I was going to call this post, Building a Rail Gun or A Gauss Rifle, but that wouldn't be accurate and it might attract the wrong kind of attention lol. This plan is a shop built Repulsion Coil. On a very basic level the tech. is similar to the two mentioned weapons, at greatly reduced power levels. The American Navy is currently working on Rail Guns that can fire a projectile 230 miles at speeds of Mach 7 (thats almost 5000 mph) and draws 6 million amps per shot. Current hurdles are capacitor banks, materials and 25 MW of available power. An all electrically powered ship is on the drawing boards to get around some of the power problems. The idea is that you will be able to momentarily switch all available power to the Rail Guns. China has done some development work on Rail Guns and has armed some of their ships with them, if you believe some of the info available on the web.

So back to our Repulsion Coil. This is a great little project that will allow you to fire a aluminum pipe section 3' into the air at the push of a button and let you defeat gravity and hover the same pipe section in thin air.

The project is in a used book I found back in the 90's. "Science Experimenter" was published by ARCO in 1964. It is full of great projects for the electrical hobbyist. You can build a small 50,000 volt Van de Graaff Generator or an advanced Tesla Coil. Think K-Tel invented the clap your hands on-off switch? Think again Walter B. Ford has plans here for one, long before K-Tel came out with theirs lol.

I have probably a dozen project manuals like this dealing with electrical, chemistry and physics experiments for the home hobbyist. They are small enough that I hope to scan and share many of them in the future, this one included.

Pictorial Textbook Of Engineering Part 6

So were nearing the end of this fine, practical and hands on textbook. Hopefully the student and the experienced have garnered information not previously available to them. In this installment are two chapters, 17 Finishing and Assembling and 18 Erecting Finished Assemblies. As in previous chapters there are lots of illustrations clarifying the concepts and methods discussed. This completes the more practical sections of this textbook. In the last section, "Chemistry For Craftsmen" are 3 parts. Part 1 "Intro. To Chemistry of Engineering Materials", Part 2 "Corrosion Of Metals", and Part 3 "Chemical Changes And Heat Treatment". These have been touched on before, in this section the science behind these concepts is explored in greater detail. Look for this last part next week.

Scraping And Generating Plates Without a Master

So here is another gem that I found in a used book store many years ago. "Practical Mechanics Handbook" by F. J. Camm was first published in 1938, this copy is from 1942.

I did not white out the background in the following pages and you can see that the acid burn is starting to brown the pages, so I will definitely be scanning this at a later date. I will share it then.

In the mean time here is a nice, short, but information dense chapter on hand scraping from this fine volume. A while back I read a back and forth on a forum concerning generating accurate surface plates using the 3 plate method. Agreement was not mutual. The description here is short but very clear in how to go about generating plates without a master (labor intensive, but thats the nature of the beast). In addition there is good information on the scraping procedure and making your own scrapers. Enjoy.

The "Father" of the "Do-It-Yourself" Category

Paul Nooncree Hasluck (1854 - 1931) has been called a pioneer of the diy movement, I would go so far as to call him the father of the category. He has authored books on the subject as early as 1878 and his numbers are unrivaled. He has authored or edited well over 100 titles. If you do a search, no one seems to be able to nail down a firm number. His subject matter covers a very wide and diverse swath of diy topics woodworking, metalworking, smithing, glass work, leather work, tin work and on and on. He even wrote a book on building your own coffin, if thats what you need lol, wow.

Most, but not all of his books are available for free around the web. The Internet Archive lists 84, some are multiple uploads of the same title,  The Librum Online Library has a huge number of titles though not all free and there are many other sites around the web, such as Google Books, that have his books available.

In addition many modern publishers have reprinted many of his books and they are available on line and in bookstores. Lindsay Publications and 10 Speed Press are 2 of the reprinters among others.

By far, for me, the best experience is finding the originals in used book stores. I only have a dozen of his books in paper most original and a few reprints.

Below is a picture of  an original 5 volume set of "Cassell's Cyclopaedia Of Mechanics" edited by Paul Hasluck and two reprints "Metal Working" reprinted by Lindsay Publications and "The Handyman's Book" By 10 Speed Press.

Volume 1 of the 5 Vol. set. Excellent shape considering it was published in 1903.

Large Tool Chests

So to expand on the previous posts subject matter, a larger collection of tools will require a larger tool chest for proper storage. Paul Hasluck had some good ideas in his book "The Handyman's Book" (See the above post for more on Paul N. Hasluck). Published in 1904, don't let that put you off, it is full of good information and lots of great illustrations and woodcuts.

These tool chests are still popular today. All the senior hands I worked with as a Power Engineer in a paper mill, all had tool chests like these. The company had provided materials and they all built their own tool chests in earlier years. They didn't hold saws and planes, rather pipe wrenches and combination wrenches, but some were going on 30 years and still holding up well. Loaded up they can get heavy, but many had built short stands on casters to wheel them around.

This copy of "The Handyman's Book" is a reprint by 10 Speed Press. It is harder to find on the web than many of Hasluck's other books and at 760 pages it is huge. I might do a multi-part upload at a later date if anyone expresses interest.

Portable Toolcase

Recently a parent of a son working towards his Scout woodworking badge expressed thanks for some of the woodworking articles found on this site. The son was looking to build a toolbox as a gift for a relative.

Following is another plan from "Woodworking Plans And Projects" of a very nice portable toolcase that would suit the typical home owner or even apartment dweller. You don't need to have a large shop or be a shop hermit to require a basic set of tools to do repairs and small projects around the house and yard. This toolcase is an excellent solution to keep your tools together, easily stored, and portable. The article has good instruction for cutting good quality, hand cut, dovetail joinery, for the novice to improve on his or her skills and produce a good quality and useful toolcase.

Manual Of Engineering Drawing

So here is a change from the recent diet of plans, "Manual of Engineering Drawing" published in 2004 has made the rounds around the web, I found this copy on The Internet Archive. A better title might have been "Manual of Engineering Design". You can only do so much writing about orthographic, isometric, and oblique projections, thousands of books have been written on the subject over the years. I have many of them in paper and on disk, and treat them as a resource for the many section and machine drawings within their pages.

This manual starts off covering drawing techniques and then moves into areas that would be better described as machine design covering screw threads, keys, fits, cams, springs, bearing technology and many other topics. It is new enough to touch on CAD and CAM design and manufacture as well. A well illustrated volume that does not get overly technical, some might even call it light reading.
