Picies didn't come through.

[jaypeezy215]

pics please!

[ohgood]

at first i thought it was pithhelmet blocking things... but apparently there was no link whatsoever.

I'm looking forward to the pictures and videos myself.

[Kaizer]

Damn it! sorry bout that. I need your help posting the pics. The help page is useless. Sorry! If anyone has a straight forward method, let me know. I tried and then hit post and well....no pics. Thanks guys!

[ohgood]

1) host your images somewhere, like picasa, imageshack, photobucket, wherever.
2) get a direct link to the image (in whatever size you like, 600x450 / 800x600 are nice sizes) and links to the full size photos for folks that may want a wallpaper/print.
3)  the code will end up looking exactly like this WHILE YOU'RE POSTING IT:

but once you press 'preview' or 'post' it will show the actual image like this:


congrats, your images are viewable now.

(without thread jacking too much)

ya, that one was a 'medium' sized prop actually. i turned 40+ foot prop shafts there. start a long cut and it might finish by 3rd shift, or still be going in the moring. fitting the big props (14' +) was a real 2-3 day event. takes 2 overhead cranes and a dozen bodies.

Are they cut from a single block of material or pieced together somehow?  They can't really be lathed...what kind of machine handles cutting something that complex?

...I just don't care about mythical chinese toys...

[coll0412]

The props are cast from a single peice. Then they go and clean up the castings with grinders and other such tools. The casts are massive, and if I remember correctly cost hundreds of thousands of dollars, stuffs crazy!

[makenzie71]

That's the way we did centrifical impellers.  Rough castings were sent to us and we did a basic cut with CNC machines, but the most work was done by hand with grinders.  That's kickass.  I'd love to work one of them over.  Are they stainless or aluminum or something else?

correct, cast. they -could- be finish machined in a simple (but big) cnc mill with a cnc indexable table, or without. with means a small x/y travel needed on the mill.

some stainless, some are a super high tech bronze mix which i'm not familiar with at all, and would mislead if I tried to act like i did. most of the impeller / propeller work that was done at that shop was only repair. the sectioned propellers were really cool to dissassemble and re-machine. apparently guys run into really big stuff and knock a 3-4 square foot chuck out of 3/5 blades, making it impossible to use above 12 rpm (vibration).

all the turning we did was just the prop shafts and tailstocks (rudder axle if you will) with occasional remachining of other BFStuff.

no, you really really really do not want to be involved with the hand grinding on a large prop. think sitting in front of a 80-140 pound angle grinder for a week, hot metal abrassively eating your clothes, noise, smoke, and a mask on. those guys worked across the street from the machine shop. it was hell in the machine shop, the grinding shop was hell X infinity. the skill and calibrated eyes over there was truly amazing though. they would flat blast off 3/8" x 4-5 square feet of material with a torch, and only need to finish grind afterwards. skill man.

they made some impeller nozzles also. no prints, just a hole in a boat that needs a nozzle. 8-10 tons of flat 1" thick plate and a biiiiiiiiiiigFing steel roller. a month later a nozzle is done, and they weld it in the ship. amazing. oh, and the impeller would fit perfectly of course.

the 'interesting' part was fitting 2' + diameter stainless bearing sleeves onto 45' long prop shafts. heat the sleeve to 300* F, lift the shaft with two cranes, get 5 guys to man handle the sleeve on, without scaring the stainless clad shaft.

and you're right:

12' prop = $300,000 average
45' prop shaft (just rework) = $60,000
45' prop shaft (new) = $120,000 in material alone; $250,000-$400,000 total

what's a good sized tug make a day ? $100,000-$300,000 a day.

wanna start a shipping company ? i'm there !

oh, and rolls royce does a fantastic job of making imp/prop-ellers. they -know- this stuff. and they charge, and charge, and charge some more.

therer, done with my thread jacking. sorry, thread originator

[bettingpython]

The bronze is a manganese bronze alloy, we used to cast in a foundry I worked at, nothing we did was that big our biggest bronze pours were about 30lbs or so per mold.

It's pretty cool when it's ready to cast it starts ejecting an ash from the top of the crucible it looks like its snowing inside and the top of the pot outgasses and flares green.
