Hi all I have an HMV 42-71 it has sat on the bench for more than 1 month.
it needs the dial restringing .I photographed the diagram that was inside the case with with the relevant information. I just cannot follow it . Where do I start? I know the gang has to be fully meshed . The dial drum would be located correctly on the shaft because it has not been distrurbed . do I attach the pointer on a length of cord first as it has to be tied around the back of the pointer or do I start with one end of the cable on the drum. I have always had great difficulty trying to interperate dial stringing diagrams. Any help would be greatly appreciated.
regards Jim.

I managed to restring this Thank you Kevin Chant for the service manual.
At first I thought it was one continuous string but it has two . One for the gang drive and the second for the dial pointer. I now need a set of knobs if anyone has a set they can sell me, it would be appreciated , in brown or cream . Regards Jim

Dial stringing can be frightfully entertaining. Some manufacturers even lashed out & put marks on the dial to indicate where you set the pointer. Basically whether setting it "S" or "Z" . The clue is to start at an end, with the gang rotor fully open, or fully shut.

Then you look at the direction for the drum that it has to turn to either take up, or let off the cordage to cause the pointer to go in the correct direction; often the cordage will lap the drum.

The S & Z applies to the driver. If it is wound with its two or three turns clockwise, or anti clock wise that will also govern the traverse of the pointer. That can often be drawn on paper & still conceptualised.

Thanks Marc.
I am just glad it is now complete . I am not a terribly patient person and dial cords tend to bring this condition on very rapidly.
regards Jim.

dial cords tend to bring this condition on very rapidly.

You're not alone. Some dial stringing arrangements were designed by lunatics determined to send others into the same mental condition. Philips is probably top of that list.

Never really had a lot of trouble with Philips but some modern stuff is just crazy. Had one recently where you were confronted with the nightmare job of a mass dismantle as the wheel (potentiometer tune) was sandwiched between two boards.

If the string is just broken (or in one case burnt) & substantially intact, do note how its strung before removing it. New springs can be obtained from engineering places.
