About a year ago I was working on a TV for the first time .
Becuase it was my first go at replacing caps and resistors I was concerned I would forget where abouts on the chassis they came from.
I wanted to remove the Caps so I could ground them and empty them of all power,before testing them with my meter.
But being new to electronics I was so concerned I would not remember where the hell they came from, so I came up with this idea to hold them in their correct position while I tried to find the problem with the set using plasticine.
Well it held them there, but I soon found out that plasticine caused corrosion on the chassis base.
So there you go , Its called learning the hard way for beginners!
I also took about 100 photos ,but the computer died leaving me with no photos for reference.

That's a pity. Not something I'd heard of before.

There are some references on the Web to metal corrosion caused by the sulphur component of some types of plasticine.

Here's a paper that gives conclusive proof that plasticine can cause metal corrosion when used to mount exhibits in museums:

Hi G,
Yeah , The thought never crossed my mind.
But thinking about it now it would also hold moisture.

There was supposed to be nothing toxic in the ingredients of the original patented plasticine, however these days I wouldn't be surprised by what they are putting in it.

One has to wonder about Maccas. Whilst they claim otherwise, their bread rolls are packed with sugar and the burger contents laden with salt. When the bread rolls have stood for a while the sugar condenses into crystals and you can taste them in the bread.

Why else can one stand a Maccas hamburger on a window sill for a year without it going mouldy or rancid? The answer has to be the amount of preservatives, namely sugar and salt.

There are a few stories out there like this one about a then 14 (now 18) year old Macca's burger:

The invention of plasticine is 120 years old - hard to imagine. When I was in infants school in the 1970s we thought it was a modern thing and in later years when listening to Fourth Form at St Percy's a joke was made about plasticine modelling by student Bottomly whilst being cheeky to the teacher, Dr Pym. At that time I knew plasticine went back as far as the 1930s when that radio play was written.

I am just glad that I only eat Maccas two or three times per year. I hate to think what some of their food does to my insides, regardless of what their scientists, professors and solicitors believe.

Actually to be honest I dont eat any of that stuff , I'm only joking about eating it.
Im on a very strict diet and have been for years , I'm only allowed to eat fresh veggie ,meat or fish.
I eat no processed food or grains and so I cook it all at home to be on the safe side.
But I do smoke cigarettes unfortunately and I must wake up and get off them .

Pete

Here's a song to give you some inspiration Pete. WARNING: It contains words with more than one meaning and the ad probably wouldn't be allowed today. Wink

Take it from me, you need to decide and declare that nicotine is your enemy, otherwise it will beat good intentions every time.

Tangible bonus is you'll have money in your wallet at the end of the week.

Just do it.

(PS: Nicotine pangs can last years. It is always trying to re-hook you.)
