Plans, projects and how-to's for home machinists

Dean William’s Web Site

I recently added Dean William’s web site to our list of “Featured Websites,” which you can find on the right sidebar.  It’s a short, somewhat exclusive list, which should give you an idea of how impressed I am with it.

Dean is an excellent photographer and he’s created quite a few photo essays and tutorials on a wide variety of topics.  He repairs cameras and so he often has to make replacements for broken springs.  The two tutorials that show how he does that are among the best I’ve ever seen about spring making.  I also found his photo essay about making a miniature propane burner very interesting and educational because of some of the tooling it required him to make or modify.

You’ll definitely want to visit Dean’s web site if you’re the owner of a Taig lathe, Taig mill or an Atlas 618 lathe because you’ll find a lot of useful information, including modifications and accessories that you can make.  Many of his projects could be resized or adapted for other machines.  You’ll learn how he makes a screwless vise, a rotary table, a filing rest, counterbores, a fly cutter, a dividing head, a slitting saw arbor and quite a few other projects.

There’s also a great photo essay about the clock he’s making along with pictures and videos of the small steam, Stirling and internal combustion engines he’s made.

Jorgensen Steam


A model of Bernays's twin-cylinder steam engine (circa 1878), built by Bob Jorgensen


Pat Jorgensen recently posted a comment and I noticed that he had an interesting web site about steam engines.  So I invited Pat to be a guest blogger and to tell us more about himself and his site, Jorgensen Steam – Bob Jorgensen’s Steam Engines and Steam Engine Designs. — Rob

My story is that I am a professional engineer and run my own consulting firm in the Southeast USA.  My Dad (Bob Jorgensen) did most of the maintenance at his family lumber mill until he retired.  Since the lumber mill was originally powered by two large steam engines and associated boilers, Bob was intimately familiar with steam engines and such.  Being of a creative mind, Bob started making simple small toy oscillating steam engine models when he retired, and progressed to the point 12 years later where he had created from scratch (34) model steam engines, (3) hot air engines, (2) steam-powered bicycles, and a Stanley Locombile type steam automobile.

What Bob did not leave was a description of how he designed and machined all those engines and things, so my task since Bob’s death in 2006 has been to reverse engineer some of the engines that Bob built, and publish that information along with Bob Jorgensen’s original photographs and hand-drawn vellum sketches.

This process got me curious about steam engine design in general, so I began researching steam engines, and have a collection of about 1,000 old steam engine engravings on Bob’s website.

I also have gotten into steam engine animations, and can bring the engines of old back to life, like watching the actual engine run.  I am currently designing a twin-cylinder steam launch engine, and hope to built that some day.

So what started out as building a simple web site to share some of Bob’s photos has turned into quite a learning experience, and I continue to be surprised every day at the variety and complexity of the steam engines designed mostly in the 1800′s, and the sophistication of the engineers who did this work.  Luckily, there are a large number of public domain steam engine design books that can now be downloaded online in the US for free, and I have posted a list of about 100 of these titles on Bob’s website.  It is a fabulous story of technology from the past that changed and modernized our world in a huge way.

David Morrow’s Web Site

If you would like to see some cool projects made with a small CNC mill then take a look at David Morrow’s web site.  It may inspire you to try CNC or give you some new ideas if you already have.  You’ll find an eclectic collection of clocks, hot air engines and motorcycle and car accessories.  His work shows how CAD and CNC can let you be more creative and quickly design and make things that just wouldn’t be practical with manually operated machines.

David made them on a Sherline mill that he converted to CNC.  He doesn’t say much about the conversion, but he does provide details about some other modifications that can greatly increase the capabilities of a Sherline manual or CNC mill.  They include an extra long and heavy base, an extended column and a flood coolant system.

If you’re interested in plans then check out Gary’s Clock 2003.  You can download the DXF file for it and David’s very detailed construction and assembly manuals for it.

Good Web Site: Start Model Engineering

Start Model Engineering is a very impressive web site about model engineering.

The site’s author, John Somers, didn’t buy his first mini-lathe and build his first steam engine until about two years ago.  But if you look at the 15 or so engines he’s made since then you’ll see that he has become a productive and skilled machinist.  He has also managed to create a very professional looking and well-organized web site that beginning model makers will find very helpful.

Right now he’s featuring an excellent tutorial that shows how to make a brass mini-torch, or what us Yanks call a flashlight.  You’ll also find a variety of other projects with step-by-step instructions, including a number of small steam engines.

I’m also pleased to see that John “Bogstandard” Moore is contributing to the web site because he is one of my heroes.  “Bogs” is both a skilled machinist and a gifted teacher who goes out of his way to help new machinists.  He has a real gift for explaining difficult procedures so that almost anyone can understand them.  He also understands that not everyone has an unlimited budget, so he tries to suggest cheaper alternatives to things when he can.   I think you might also enjoy his sense of humor.  I suggest keeping an eye on this web site.
