Plastic Batter Cover
I spent a short while making what I thought would be a suitable jig.
The came the task of melting some plastic and milk bottles cut up into small bits in a tin can seemed a good idea
Unfortunately even at 280deg C (the max our oven could produce) all I got was a sticky burnt toffee and a smell in the kitchen. Whilst milk bottle plastic apparently melts at about 150 dec C it still doesn't flow.
I did expected something like hot golden syrup that would pour easily.
Not to be deterred I contacted a local plastic moulding company for advise and arranged to go in and see them yesterday. They very kindly spent quite a while trying to help out. For the record, moulding machines work at 240 deg C, but inject at about 30,000psi (if I've remembered the details correctly) so hand filling a mound with hot plastic was always going to be difficult- However the following pics show the outcome.
Its yellow (thats the colour of the material they used) its stiffer than the clear K10D one because I made the female part a bit generous and its therefore thicker. Its a bit of a tight fit beause I hadn't taken into account shrinkage, but better tight than sloppy.
So all in all I'm a happy bunny

Doesn't the K10D plastic holder fit the K-5 battery?

Algi - The plastics man I went to see yesterday asked how many I wanted and happily was prepared to "play", to make me what I wanted. The machine uses heated steel dies which cost thousands to make so unless you need a few hundred thousand - I wouldn't bother.
The K10D and K5 batteries are different (at least mine are). The K10Ds is a bit like 2xAAs side by side with one flat surface and a groove on the top. The K5 is flat both sides.

springs off possibly due to the valley part that goes between the
AA effect cells. Probably be OK if this was cut off?
Edit: Yep! Took about a minute with an X-Acto
knife... I left some of the curved valley bits in so
that it springs against the K-5 battery. There's no
positive/active clip holding it on, but it should stay
on OK. I might put a small piece of masking tape on it
to be sure
It can still be used on the K10D battery as well.

I don't have any old K20D batteries, nor the skill or (more honestly) the inclination to start messing around with plastic.
I just half covered my battery in Marzipan ... looks just as good and gives me a tasty mid day snack should I get peckish.
Actually you've set me thinking again. When he was a kid my son had some green silicone type plastic which he would melt in Bain Marie manner then pour it over things.
The oject was to make a mould he could pour plaster of paris into.
I bet that stuff might work. (and not tempt people to eat it). I wonder where he might have left it (We have a loft full of toys and his cast off belongings, just waiting for the day he says he's got a house with a loft )

You absolutely sure its marzipan and not gelignite, same smell. Not sure about taste.
Take care.
