Things are tough right now ...

They're tough for everyone :( But when coronavirus hit here in the UK, the museum had to close its doors to the public, and we lost practically all our income overnight.

Please Donate Via Just GivingNo visitors, no workshops, no events, no school visits... no income. We know that things are tough for everyone right now, but if you can afford to help us through these tough times please donate what you can.

There's over 36,000 exhibits here! That should keep you occupied for a bit - get searching!

Paper Tape Correction Jig

Paper tape repair / correction jigs. The picture shows small and large versions used for splicing and repairing. The punch could be used to remove extraneous chads or create new holes if required. (e.g. if the parity hole had been missed by the prep machine)    Superfluous holes could be covered by splicing mylar but most ops learnt it was quicker to find a loose chad, moisten it with saliva and ‘glue’ it back in the unwanted hole.
