I've just acquired a Zippy 90 and it's fine except for the sponge strip
which is virtually useless. I also have an LK150 which has the same stuff
and is in much better condition. Does anyone know if replacement sponge
strip is available anywhere? There is room in the Zippy to insert a normal
metal and sponge bar from a standard gauge machine, albeit too long, so I
will probably try that for now, but I'd like to find the proper stuff, or a
reasonable substitute.
TIA
