Default Tempering music wire

Had to heat up to red hot 3/16" music wire to bend for some landing gear. My question is, how do you re-temper the wire after heating it to that high temp. Any help will be appreciated.

I bend it cold, making certain that the inside bend radius is at least 3/16".

You need to get a wire bender . I use the big & small K&S ones . The big one will handle 1/4" music wire as long as you have a good vise to hold it . Max H.

Since it's too late to bend it cold, heat it to red hot (all of it) and quench in water.

Then clean it ans slowly re-heat it until it becomes a straw color - then let it cool slowly.

And next time, bend it cold

First time I bent my own wire landing gear I heated it up and did one of the best jobs I have done to date. First landing both wheels went south on me with the axels still attached. It was pretty ugly!! I have tried to temper different metals over the years but really stink at it. In tenth grade metal shop I had to learn tempering by making different tools, never worked for me, we were using the color chart, I'm color blind!!!

You're prolly color deficient. Most common for males is dueteranomalous (green deficient) and will have difficulty matching hues around the green portion of the color spectrum. There might be one person in this world today who is truly color 'blind' (only sees various shades of gray) and has correctable to 20/20 vision which would be the result of an extremely rare genetic defect or some highly specific vascular insult to the visual cortex. Folks with some forms of albinism are 'next in line' with poor visual acuity and color perception. There are other disease processes and chemical/ medicine toxicities to produce poor color vision but they also reduce central visual acuity. P.S. yes, I am an expert in this field and, no, I won't elaborate! It's fun stuff, though!
