Several coats are necessary and each must be baked for about 10 minutes at 200°C so that it is quite hard before the next layer is applied.

The insulated wire is placed in a Tufnol clamp and ground flat at the end by hand, using a very fine hone. Mechanical grinding, with a jeweller's wheel, is not satisfactory as it tends to spread a thin layer of metal over the Suture Bare back end of electrode. Skin^ Skin fold Suture Electrode
