This proved very successful and also produced a better tone from the string, a couple of days ago I noticed a slight "dullness" coming from several strings when I ventured above the 12th fret, getting adventurous I tried the same bodge using 0.0006thou brass shim under each string and was surprised at the difference in tone it produced and how different the sound was when going up the board, now I can go "where angels fear to tread" with great success!
The shims are hardly noticeable and the slight overhang of the brass shim does not effect the sound in any way as it's only a few thou and to awkward to get dead on size. Photos below should explain everything.
Holding down the brass shim, a knife edge was used to bend the brass over it and I used a pair of tweezers to put it under the strings one at a time after having cut the shim to shape with scissors.
As it has proved to be a success I decided to let others know about it, as there are sure to be old lap steels that can be improved by this "Bodge"
"Bodger" Bob strikes again!
