Thanks Bill, I think that is a great idea, I have been using anti-slip matting fixed with double sided tape. But your idea should make it easier.
Cheers Colin.

Great product.
Thanks for the info.

Gents.
These may be of use to you as anti vibration pads for delicate items including RX gear.

Due to illness I have had a massive weight loss to the point where my wedding and signet rings were sliding off my fingers.
I found these on Amazon which are ring size reducers.(No Rude pun intended)
However I also found that they are brilliant for modeling.
In mg case I have used them for seating a motor and RX components.
They eliminate vibration but alow flexibility in slight movement.
One side has a good sticking surface whilst the other is clear.
For some reason I am unable to down load the Amazon link but they cost £3.99 for 152 different sized pieces.
The Amazon product number in the absence of a link is BOBNPV1NTR.
There are many other similar product as well.
May be of use to someone out there,certainly floats my boat !
Regards
Bill.
