Just finished making a rear set trigger for a Dickert build. Using a Davis golden age trigger set but couldn't get the rear trigger to look correct, so I made one from an old file(annealed of course). My question is about the hardening and tempering for the rear set. I was planning on the usual heat to cherry red(non-magnetic), quench in light oil then temper. I would assume tempering to around 600 degrees(blue) would be appropriate, but figured I would reach out to those most knowledgeable first as assumptions don't seem to work for me. Also, I was going to try tempering in a skillet I use in the shop filled with sand for shading veneers on wood projects. I took a temperature reading and it can hold around 520 degrees. I was thinking of "baking" the piece in the sand for about an hour, but again figured I should ask if this would be not such a great idea and just polish and go with the torch to temper. Thanks.
