Default Grundig 3040M

Hi everyone, firstly I hope this is in the correct area.

I have a couple of questions, firstly there is no colour left on the plastic tuning indicators (see photo) would this have originally been red and any tips on fixing this?

Secondly the tuning clutch seems a bit sticky as the FM running can move slightly when running in an AM station. I'm weary of hitting it with oil does anyone know how to service these?

Much thanks in advance
Andrew

A drop of red nail varnish works well.
The clutch will need to be taken apart, cleaned and rebuilt. You will also need to replace the rubber 'clutch plates' to get good smooth operation.

Is modern nail varnish still made with Acetone?

Could the Acetone damage the plastic pointers?

Humbrol still make the little tins of paint and there is a bright red in the range. Finding a model shop these days that sells them might be more of a problem though! The usual on line sellers have them but the postage makes them expensive.

I've used aerosol paints for respraying pointers. Overkill though unless you already have some.

Hobbycraft have retail premises in Hull (Kingston Retail Park, Unit 4B, Kingston St, Hull HU1 2TX) and the company offer Humbrol tins (https://www.hobbycraft.co.uk/brand/h...lowsearch=9871)
Worth a look I would have thought...

Nail varnish is basically a brightly-coloured plastic material, dissolved in some sort of solvent which evaporates quickly (usually ethyl ethanoate). Nail varnish remover is a solvent which dissolves nail varnish (usually propanone {acetone}) and not quite so voltatile, so the solution stays liquid for at least long enough to be wiped off with a tissue.

Since the coloured polymer itself dissolves in both solvents, it's reasonable to suppose that a substance which is soluble in one will also be soluble in the other. As they always say, test on an inconspicuous area first .....

Humbrol etc can also frequently be found in toy shops, near the airfix kits.

If you have a branch of "The Range" near you, check out their arts-and-crafts section: my nearest branch has a whole range of 'acrylic' paints in small containers.
