Hints and Tips.
To protect and stop vibration on those mechanical or electrical items I use as shown in the photographs below.
Easily obtainable from your local double glazing outlets they are normally placed on the outside of the glass units to stop them rubbing together in transit.
They are plyable and one side is tacky so they will adhere to your components without leaving any residue.
I also use them for Engine block mountings.
Certainly at my local store they are happy to give them away.
Take care and stay safe.
Regards Bill.
Edit.
They are very easy to cut with a good sharp model knife or scissors.
