Practicing fillets, this fillet is mine but I see the same reddish hue/color on some pics the pros post. On another forum it was suggested it might be a bit of overheating and copper beginning to pull out, thought I'd post the same question here. Could it have to do with the flame being carburizing or reducing? Input appreciated, as always.
thanks, Brian

Work hot. Work fast. It's all practice.
The picture is only a small example of what happens with the human experience.
If you want all of these to look textbook perfect, it'll take a programmed machine.
That said, the radius of those brass sections isn't consistent, but at least you can file it back.
Yeah I understand that, well aware of the radius issue, still curious regarding the color.Quote:

Below is practice(fillets and running beads) over the last 3-4 weeks, a few a day on most days.https://i.imgur.com/8SeSU6q.jpg

My mother was a career educator starting as a pre-vocational girls director, then a teacher, and then a vice principal, and later a principal. After she retired, the state Board of Ed hired her to mentor others who might some day become principals on their own. In reading all the notes and manuals she (her name was Bobbe, short for Barbara) would continually hit hard with the same piece of advice about relentlessness, followed by three simple words (unless you don't get it): See it done.
The other ploy is to watch a metric shitload of videos made by folks brazing for a living, folks you trust that is, and then play make believe. Here's Hendrix willing the flame across his ax. Yeah. It's theatre. But the point is that you have to will the filler and the areas to be filled and do it regardless of the torch setting. However, I do believe hot and fast is optimum. This should address your earlier ask about reducing and carburizing flames. Show the joint who's boss.
Oh, the theater:

I like a pretty neutral flame, reducing oxygen will make the flame run a little cooler. You are getting it a little hot, as you have been told. You can see the burned flux at the edges, and when the flux burns it stops working. When the edges burn you're just a half step away from burning the rest of it and scrapping the joint.
I'd recommend trying to move a little faster with your current flame, or reduce the size of your flame and keep your travel speed. Also, adding more filler will help reduce heat input into the tubes bit. You'll have to decide how big you want the fillets and adjust everything from there.
I hope that helps.
Thanks to both of you for the input.
Would love to see some of your glass work in the non cycling hand made area.Quote:
