Hi thanks I tried that, just by doing the outline but it just looks inflated and the original letter stays the same size which is not 1/2 inch.
Found another way by making 1/2inch rectangle shapes and stretching the length and angle to fit into each letter. Which is good in one way as it tells you the length of each one and the Led neon can only be cut at 1 inch spacing.
For any of the curved sections it was a case of using the elliptical tool to make a shape which fitted perfect and then making a duplicate and then grabbing the corners to make a smaller version.
Then a bit of node editing and weld them together. All a bit long winded
