Hi Bill: Of course any clockwork mechanism can be designed to be powered by a falling-weight drive, but it would be hard to beat a motor/gear driven unit for compactness & simplicity. C. --- bill biesele <xmix@biesele.net> wrote:
If a field derotator is a 1 rpd drive couldn't one be built with a pivot and counterweights? Axis of pivot would be parallel to optical axis, counterweights would hang down to drive rotation at 1 rpd by gravity.
Wouldn't want to use it in a wind, but would it work?
