    This time a compact 1979 Aiwa L22, as always all the bands are perished,
    that contagion again . I decided, this time, to liberally caster talcum
    powder around the contaminated parts , my hands and goo pickers. Operating
    at that stage , dry and dusty, avoided smearing on other parts, to remove
    the bulk of the mess. Then meths on tissue paper and meths for general
    smeared areas and some wool dunked in meths to run around the pulley edges
    to clean out the gullies.
    Anyone ever tried freezer spray?
    My own cut silicone rubber bands will go back in there

    Just querying what this refers to? Having recently been through a third
    band replacement with my ancient Aiwa FX-90 (part of system rack) and
    had to bodge with an undersize band from eBay as originals no longer
    available! C+

    Originals are of course as near to perished as the ones you're having to
    replace.
    I tend to use silicone rubber as much more available from "pound shops" /
    kitchen supply shops etc rather than large minimum square metreage of
    industrial neoprene rubber supply companies, techniques buried in the 3x
    tips files off my site

    The wide band for this Aiwa I will use a ring from one of those squash down
    silicone rubber funnels ,
    , just a shame about the lurid colours of the rubber

    In the UK I get them from Matalan, gives 20 bands of a good range of lengths
    and if 3mm wide then can be split for 40 bands. The slight set to the band
    does not seem to matter for centalising the band on baluster pinions

    Thats the main flat band sorted, the rest are less critical.
    Original unstretched 285mm x approx 3.5x1.5mm. Area for area, silicone
    is more stretchy than neoprene , so about 50% allowance for that, a now
    working band of unstretched 250mm x 4x 2mm. Target was 265mm x4x2
    ,probably turn out to be too tight on speed check and will have to
    resort to cutting up my next size up solid silicone funnel as 250mm is
    the max,outer ring, for those collapsible funnels
