A simple clockwork mechanical timer. Just turn the knob to desired time and
walk away. Maintenance free and no batts. Unfortunately it has developed a
leak. Possibly because of age or perhaps frost damage. Not a huge problem as
it is in a utility room. It is not going to get better and does not seem to
be repairable.
I've googled for similar but can find nothing. All seem to be battery
powered electronic gadgets. Don't really want this if it can be avoided.
Any ideas where I might find a simple mechanical timer?
Thank you,
