Personally I would’ve beveled it out quite a ways to get more surface for the brass to bite on. but otherwise it seems like your procedure is excellent
I had debated doing that as well. If the brass hadn't washed all the way through to the other side, I would have cut it out and done it again.
Very helpful and very informative useful video this week. Thank you so much. Can't wait to see more videos soon my friend. Keep up the great craftsmanship and hard work my friend. Forge On. Fab On. Weld On. Keep Forge lit. Keep Making. God Bless.
Thank you for the praise! Put a lot of effort into this one.
That brazed repair won't hold up to much stress. Don't put more weight than a mosquito wing on it. Also just because it was sand casted doesn't mean it is cast iron. It could be a cast steel part. Grind it a little and look at the sparks. Cast iron sparks look different than cast steel sparks.
It's held up for over a year+ and the client has been happy with it. If it can survive a bunch of high schoolers at a public school, I'd say I did a decent job.
Very nice, but I wish you would have talked a little more about penetration. Still a great video.
@buckygoldstein9256 Fair enough. Penetration is a bit strange with brazing. Since you're not bringing the base metal up to a critical temperature, you're not actually creating penetration in the same way as you would with welding. Instead, you want the brass to "seep" through in a similar way to soldering. Thank you for watching.
@@steelforestweldingandforge Don't get me wrong. I found the video very informative. I've never brazed cast iron, but I have brazed lugged bicycle frames, which is sort of like sweating pipes (but with brass and steel). With bicycles penetration is very important for strength. I was watching the video because I'm contemplating brazing a broken vise, using nickel silver rod. I'm not sure how that will work, but I'm sure that penetration will be important with that also. ;-)
Brazing in almost all cases should be done with a 2X reducing flame.
