You're right...he knows the $hit that comes out of his pants.🤣🤣 Normally diesel pistons are forged aluminum, then again we're in India or Pakistan anything goes. That engine will self destruct in no time

@@caddyrack How do you know this? I think the shit you talk about comes from your mouth.

@@dayleedwards3521 Hey genius, check out how pistons are made especially for diesel engine. Is your brain made in India?

@@caddyrack You are choking on it.

If they seized these guys wouldn’t be wasting their time making them daily would they? You lot are negative nannies about everything these guys do, if it’s not pointing out a thousand times about their footwear, safety or other, the you attack their product. Go watch some other channel then.

I think what they do is amazing with what they have at hand and am not rubbishing them that is why I enjoy watching them. What I am saying is what I know from making pistons and am intrigued as to how they will last. Ps you know more than I do after having been in the industry most of my working life?

@firstlast-ty4di Amico mio, tra gli " ingegneri delle tastiere" nei commenti potrebbero esserci ingenieri laureati,meccanici (come me) che hanno lavorato sui motori per >25 anni e che magari hanno montato decine o centinaia di pistoni nuovi,cioè gente che di motori ne capisce sicuramente più dei "tecnici" nel video,tecnici che ignorano unità di misura come il centesimo o il millesimo di millimetro,i loro "strumenti di misura" lo dimostrano...

@@fasullodavvero Yes, many comments are valid, but many others are very uninformed. These Pakistani workers are not attempting to make pistons for a Formula I racing engine. "Hundredth or thousandth of a millimeter" (.0004" or .00004") are not needed here. I'm guessing that the tolerances on the design drawings for the original piston are much looser than that. These workers showed some very intelligent improvising. Did you notice how the broken piston was wrapped with a thick material to make a pattern for the sand mold? That was to allow for the thermal shrinkage of the new casting. Making a new pattern would be very expensive. Chucking the piston on the lathe to bore the wrist-pin hole also impressed me. Keyboard warriors tend to diminish the skills of workers in developing nations only because of their lack of access to modern machines and instruments.

@@firstlast-ty4di Amico mio,sono cosciente del fatto che quei meccanici,fonditori,tornitori fanno quello che possono con quello che hanno,ma in casi simili è solo tempo sprecato,quanto alle tolleranze,non è questione di F1 o altro,anzi,è proprio il contrario,fare un pistone che duri molto è più difficile,specie se non disponi del know-how e i materiali per farlo,io ho studiato in una scuola professionale prima e fatto il meccanico per >25 anni poi e non ci provo nemmeno a produrre un pistone,al 99,99% sarebbe un fallimento,già solo riprodurre correttamente il profilo del pistone è impossibile se non hai le misure corrette (i pistoni *NON* hanno lo stesso diamentro in tutti i punti)e le differenze si misurano in determinati punti in centesimi di mm...

@@fasullodavvero The need for precision, itself, is a vast area of study. Approaches such as six-sigma examine how tolerances and variability of finished parts influence to performance of a completed system. There is a point where increased precision will not improve quality commensurate with cost. I don't know whether the piston produced in this video will be put into an engine or whether it is only a demonstration. I do think that the method shown can be useful in situations where supply-chain delays are prohibitive and a piece of equipment must be put back into service quickly. In the USA (or Italy) mechanics and engineers take great pride in being ably to order a new piston and take delivery the same or next day. The piston will be shiny and meet all manufacturer tolerances. Of course, we wouldn't go to a foundry and machine shop with drawings and ask to have one made. We have industrial resources not available in Pakistan. That does mean that we are superior mechanics or engineers. To me "keyboard engineers" have false pride in the good fortunes of their birth places. I would liken them to those who would ridicule someone in a wheelchair.

@@firstlast-ty4di Perfetto, vedo che *NON* hai capito quale sia il punto,cioè che il lavoro che vediamo in questo video è semplicemente inutile,la fortuna non c'entra,quando non ci sono ricambi, si butta tutto,quello che vediamo nel filmato è "accanimento terapeutico" , è come voler curare la peste con l'aspirina,non solo non guarisci,ma spendi denaro per curarti...
