discussions on this website, reference is made to a variety of tasks that
can be carried out on Hammond organs (largely concerning routine maintenance).
The degree of complexity for each task is indicated by a grading system,
from 1 to 5, the significance of each grade being as follows:
1 = A very simple job requiring no particular
skills, and few tools.
2 = If you are handy, and have a reasonably equipped toolbox, you
should manage this job.
3 = A complex job demanding skill and patience, and requiring a
broad selection of standard tools as well as some special ones.
4 = A job for your organ engineer, with electrical
and mechanical workshop facilities.
5 = Should be undertaken only by an experienced
Hammond specialist, with full specialist workshop facilities and complete
you intend to do a job yourself, bear in mind the following:
Create a spacious working area for yourself, with bright general illumination.
Have a strong, small torch at hand.
everything really clean - the work surfaces, the floor, your hands -
and clean off all dismantled components with a rag.
slowly and carefully, noting the order and orientation of the dismantled
parts, or laying them out in order on a cloth.
the absence of special jigs, fixtures and test gear, it can be useful
to have another person at hand to assist you.
