Post subject:  Clear Plastic/Perspex Repair

I have an enigma wheel set in plexiglass as a paper weight. It was given to my great uncle on his retirement from GCHQ. It has been in my care since he died about 15 years ago. It was recently dropped by my auntie (his daughter) and a large section of the clear plastic has detached and she has since lost the piece. Does anyone know of a way to build up the damaged area (like a windscreen repair) so i can at least make it look better.

The Cypher Museum in Holland say its a very rare item and couldnt be replaced!

Thanks guys!

If you search "repair clear resin" you will find products that maybe suitable e.g.

You would need to make a mould around the paperweight to keep the overall shape.

I've never tried this myself and as it is so rare a professional repair might be the best answer.

That is exactly what I'm looking for. I searched for ages for a DIY kit and never found anything like it!

Thank you very much!

Long time since I asked, but...Ive ordered the small kit and going to give it a go once Im home. Anyone got any suggestions of how to make the mould/shuttering?

The piece is approximately 5" diameter and 2" tall. The chip is approximately 1" square on the top rim. I am thinking along the lines of milk bottle plastic or a good thick tin foil.

TIA

Hopefully the instructions will give you the answer. Another way to shutter it, is to use Plasticine (or similar) but do a test to make sure that the resin and Placticine don't react with each other.

Dont use plasticine unless it is gfaced with something else, it will be dissolved by the resin & you will end up with a horrid mess.

Best to make shuttering with foild covered card or pieces of polythene.

Personally I would be messing about with something like this myself, I'd be getting a decent job done by someone who knew what they were doing.

An Enigma rotor is worth a couple of grand, let alone the sentimental value something like this holds.

Nice item to have...what a pity he didn't come away with a whole machine!

Good luck with the repair.
