Preliminary assembly of test stand
The previous page shows a photo of my test apparatus in its early stage of development. It was pretty much pieced together in the photo,
although I had not yet attached the stator arm. The frame is made of 1 inch PVC pipe and fittings, so is quite lightweight, yet is of
sufficient strength for my purposes. You can see that my rusty, salvaged junk Huffy 26 inch steel bike wheel is mounted between two steel
plates attached to the PVC frame. And that's it, basically - a very simple and straight forward build. You might ask why I would choose to
use this junk wheel, and the answer is simple - it was free. I love to make use of free parts whenever possible. The wheel rim was bent
when I found it, but I straightened it out enough so that there is only about 1/8 inch of runout from side to side. The bearings aren't all
that great either - I cleaned them and applied fresh wheel bearing grease, but it seems that at least one of the bearings has a flat on it, as
I can hear an audible imperfection as the wheel rotates which sounds almost as if there were a grain of sand stuck in there. I'll see if I can
round up replacement bearings, but will go ahead with my tests regardless. I figure that if my rig works well with this wheel then it can
only do better with a good wheel and bearings. You will want to start looking for your wheel. You may get lucky and find one at your local
recycling center, or find a good wheel on a used bike selling inexpensively in a local newspaper or on craigslist classifieds: jobs, housing,
personals, for sale, services, community, events, forums on the Internet.
Step # 2 of Construction techniques
In this second step of construction, I show how to build the pieces that connect the two ends together. This step is shown in two parts,
part 2A and part 2B. The first photograph shows the individual pieces as joined together to make up the front and back rails, and the wheel
support members, while the second shows how these assemblies are then joined together. Between the two photos, a chart will appear
that identifies the various parts and their dimensions.
