After (quite literally) years of development, the x-y Easel got a big upgrade this month.  Since the beginning, the linear bearing arrangement has been less than optimum, what with trying to keep costs down and trying to adapt existing easels.  I finally ordered up two 5′ long linear bearing tracks along with a precision ball-screw feed, straight from CNC router technology.

The feed is silky smooth, quiet and really strong.  To accommodate the rails, I designed a new easel frame, built from baltic birch plywood, which is mad-strong and really light.  In addition, I was able to incorporate all the new features into one easel – the handheld remote, the massive battery power supply and the computer interface.

There are a few things I’d like to tidy up – I’m still not happy with the finish, and the next easel will be stained with a deep walnut analine dye, and rubbed out with a dark Danish oil.  The computer interface is still Windows only, and I’m working on a little different strategy – doing away with the computer control entirely and using Arduino to set up a programmable hand-held remote – even with a smartphone app possible.  Stay tuned!

In the meantime, I have enough spare parts left over to build a little side project I’ve been getting some interest in: a wall-mount easel.  I’m putting that together and will bring it into the studio for some lengthy testing within a week or so.



Power in Flux is Done!

February 21, 2017


It’s been a long haul, but the book, Power in Flux: The History of Electric Motorcycles is finally complete!  Read all about it here, on it’s very own website: Power in Flux.  350 pages, available from – hardbound with dust jacket, soft-cover, and electronic formats are available.

Two things.  Writing a history, especially when the people who made it are still alive?  No small task.  And if anyone ever tells you that “What’s on the Internet is on the Internet forever”, they’ve obviously never tried to research anything on the Internet.



We made it!  With 4 days to go, Power in Flux: The History of Electric Motorcycles got 100% funding at $10,000, and is still going strong.

Why do I love this?  Well, for a number of reasons, beyond the obvious.  First, it shows me that it’s not my personal grail or indulgence, and that there’s interest and demand for this kind of work in the EV community.  While I’m talking about community, it’s been really amazing how many people have spoken  up and reached out to help – with resources, information, some gossip, and lots of details.  I also can see where the support comes from, and that there’s interest outside of just the electric motorcycle community, the EV world, even the world of gasoline motorsports.  The goal has been to write a book that reaches beyond the niche of the niche that electric motorcycles is, and it seems like there’s interest out there.

A HUGE thanks to the backers and everyone who’s helped.  …and if you still want in, there’s still time.  Order your book here.

Now the work begins!

Screen shot 2015-06-08 at 5.58.48 AMFor the last 8 years or so, I’ve been keeping track of resources and news about electric motorcycles over on my The Electric Chronicles blog.  It wasn’t until recently that I realized that what I had was a pretty complete history of not only recent electric motorcycle development, but not-so-recent history as well…  such is the nature of obsession.  I also realized that it was a fascinating story of how science, technology, research and the market come together to make a revolution happen.

So I started a book.

What I find most interesting is about how the timeline of electric motorcycle illustrates bigger subjects of technology and innovation.  We always hear about “Think Different”, but one of the key patterns in innovation is watching how individual pieces have to fit together to make that “Different” happen.  What we know as the modern bicycle, for example, went through almost 50 years of fits and starts, through several interpretations of a two-wheeled, human-powered device…  but until three unrelated bits came together – a manufacturing process that could make tube steel, inflatable, pneumatic rubber tires, and, most interesting, industrial roller chain – could the modern concept of a bicycle exist.  The parallels in electric motorcycle development make this a fascinating story of 21st century innovation.

This is a book that will interest not only EV enthusiasts and motorcycle fans, but anyone interested in how breakthrough ideas incubate, fail, and succeed.

And, I started a Kickstarter campaign to fund the book.  Take a look: Power in Flux: The History of Electric Motorcycles.  If you’re interested, I hope you’ll consider backing the project. In the first 24 hours the project hit 25% of the funding goals, and 50% in a few days.

What’s most exciting, and personally satisfying, is how the electric motorcycle community has embraced and supported the project.  Where I once had doubts that this was anything but a personal obsession, the community has stepped up and unequivocally weighed in: this is an important project, and people want to support it, both with their dollars, but also with information, resources and contacts.
