When Johann Bessler exhibited his wheels, they were of a certain depth or thickness, being covered on both sides of the wheel. I assume that the cross-bars or pivots upon which the levers or weights turned, ran across the internal depth of the wheel and each end was fixed to a piece of timber on each side of the wheel. Witnesses report that the sides of the wheel were covered with oil cloth and others that there were gaps in some thin timber planks that covered it. This suggests that the wheels were built in a skeletal framework with easy access from both sides as well as the circumferential edge, then the interior was hidden by the oil cloth or the thin wood deals - not as in my prototypes which consist of a single wood disc mounted on a removable axle.
Its hard to explain without a drawing but its a simple to understand; I call Bessler's wheel a three dimensional build having depth as well as height and width. For simplicity, my prototypes are built in a two dimensional way having height and width but not really any depth. By that I mean that the same cross-bars or pivots I referred to above are only attached on one end, in my case, to a single side disc, or back-plate, thus dispensing with the need for any kind of structure on each side of the wheel and allowing easy access and adjustment.
From Bessler's perspective his wheel had to built as a framework of pieces of timber rather than two discs because of the increased complexity of fitting the cross-bars and any associated mechanisms, in-between two discs, but I'm sure his experimental models were built in a similar way to mine because at first he only needed to make a proof of principle wheel for his own satisfaction, and then build something that would keep the internal mechanisms safe from prying eyes.

I had thought that if I was to succeed in making a working version I would need to either rebuild it with two solid discs, one for each side, to mount the mechanisms on, or try to attach to the open, uncovered side, some kind of covering to hide the internal workings. However when I decided that I wasn't going to keep the workings secret it was obvious that I could just go with the first working prototype. But now I'm aware of what a mess the basic disc I use to mount everything on is! Its got more holes in it than a hunk of Swiss cheese! The metal levers are similarly riddled with holes of assorted dimensions. What to do! In the end not much. I might apply a little paint to the disc to make the mechanisms show up against the background of the disc..... but I'm getting ahead of myself - first I have to build that working model!
