hanging parts and pins

[Olle]

If you do this in the oven you need to make sure you leave it in there long enough for the entire part to reach the right temperature. The color depends on the temperature in the steel, so the thinner parts take on the color first since they heat up quicker. It seems like the thicker part on top of your trigger didn't get much color, so try and leave it in the oven longer next time you try it.
