I'd love to know which "crack repair procedure" he's referring to, because I've never seen one. Problem is that having attacked the spindle with his grinder it no longer qualifies as a Reman Core.
Unless he welds it back up and grinds it smooth.....
It might not have qualified as a reman core anyway. It's broken beyond repair. CEE is a very reputable outfit. I don't think they would consider a repair on a large part like that without talking to Cat first.
That is because you are not a youtube celebrity. Nah I actually think the chap on that web channel is quite talented and intelligent and having a bloody good go. I have seen the odd questionable thing done that I knew would not achieve optimal results and I am not going to comment on welding 793 stub axles as I have no idea. I think he is doing a good job showcasing the industry and young people might watch it and think about becoming a fitter and turner as a career. We are now starting to see lots of female participation in the trades in Australia. Unfortunately it is others that try to turn people into messiahs.
I've watched several of his videos and he does a good job of explaining things and keeping it interesting. I believe he said he worked at a mine for several years before going into business for himself.
