Without regard to knowing how to use sand molds, why go through all the trouble to make a part that isn't going to last? Making a gear out of junk aluminum (just any old aluminum - throw it in there), with the precision of mashing the misshaped sand back into place (that's close - that'll do), and come up with a gear that will be chewed up by anything running next to it. This is India's machining version of India's technical support.
Why did I only get notification about this video today? Never mind, I still find aluminum casting very interesting and I wonder how this sprocket/gear hold up regarding wear and tear. What does he use to off gas the melted aluminum... borax?
I do casting using sand and clay why use molasses? I it seems like it would be messy and hard to work with I've never heard of this before I don't see any advantage of using it
Hello, What proportions of molasses and sand does it take to arrive at this molding sand? Once again, my sincere congratulations on the quality of this work, done with so few tools! Long and happy life to you!
I've done aluminum casting but always using sand and clay what is the reason for using molasses? It seems it would be messy and hard to reuse also is it reusable or discarded? Casting or green sand can be sifted rewet and used over and over what is the advantages clay is just as readily available it seems molasses would be messy and hard to clean up I've really never heard of it being used for this purpose
Great job, man! I'd much rather an item be handmade than cranked out in factories by the thousands. The quality is a testament to his knowledge and skill. Great craftsmanship used to be highly regarded, and something to be proud of. Have you thought of casting any artwork?
Believe me, that this wheel is a temporary part to be used. You would not wish to have it on some crucial part in your car or motorbike. Do not take me wrong, this is not about dehonestation of this man or his work. It is incredible how he can recreate scrap into someting useful. However, there is a reason why such parts are usually created by thousands in factories with precise machine work and controlled for quality.
