Prop Shop Vietnam

[wierdscience]

New channel popped up in the sidebar awhile back, guy goes around visiting various boat yards and machine shops in Vietnam. No English translation, but still interesting.

Those are some pretty good sized props, but don't look like the usual Bronze alloy, the color seems much lighter. Maybe Aluminum Bronze?

Seen Aluminium bronze also on local prop manufacturer:

Looked like purely aluminum. At about the 6 min point you could see numerous big bales of what appeared to be aluminum cans.

Interesting video. Too bad I don't speak the language. No clue as to what he was saying.

How many safety violations can you spot?? If they have any there ! Like the guy walking around wearing sandals.

I thought that the shaft size looked small for the diameter of the props. Aluminium is probably cheap there, think of all the old B52's laying around.

My guess is the white metal is stainless. Aluminum is too soft. And yes, my guess is the yellow metal is an aluminum bronze.

There are hundreds of alloys...

I figure that's what the Aluminum cans are for, they are making their own alloy on the spot.

The Vietnamese people are enterprising. I may be wrong, but I did not see any CNC equipment there. Is it all manual machining work?

If those propellers/screws are for their naval ships, I don't think our subs will have any problems finding them.

[lynnl]

I don't think our subs are looking for them. ...why should they be?
We've been down that road before. Those people, like everybody else, just want'a pursue life and happiness.

I enjoyed it. Thanks.. Google or chrome has a translate feature. Within the translate screen there is a microphone. I used my phone to listen to my desktop and it translates. Fairly well. JR

I know the hopes and dreams of at least some of the people of Vietnam. I was there. They are much like our own.

As for my comment, it was a MACHINING comment. From the looks of those screws, they weren't doing a very good job. The screws are probably far from ideal as far as efficiency is concerned.

They might be "blanks" that get finished off somewhere else? JR

Those props are for their fishing and general river cargo boats. When you are looking at the video, check out the others listed on the right side of the screen. They are well worth looking at, some are hilarious, especially the mele of craft fighting their way upstream through a river barrage.

Well their latest vid explains it, they make both Aluminum and Bronze props-

In the first video if you turn on captions he explains the props are aluminum. I also love how it shows one guy on the lathe wearing open toed sandals
