zedprime posted:Is the recycling of swarf from purpose tooled machines deep in the supply chain really that dismal or is the recycling of swarf from shop CNC cutters really that amazing? There's examples where a shop is able to bid the parts to be barely over the raw materials cost, because they're able to effectively collect and recycle the chips that are made at a profit. You need to be making a truly stupid amount of the same type of chips though, and have a really solid relationship with a very close by foundry. If you make 5k pounds of 6061 chips a day, you can probably get some pretty great rates from the metal recyclers.

I guess it also depends on just how good you are at keeping types separated and if the foundry has a long enough working relationship to trust you on it.

that staircase is built out of 3/4 plywood and each plank is like 2' wide, and scarfed to the main support pole. you could walk up those steps on each individual plank. HolHorsejob posted:It's this. Those slats are just rectangular strips of maybe 1/16" mild steel slotted sideways into a frame, and the frame the slats sit in is just a strip of maybe 1/8" mild steel with slots cut to hold the slats in place. The jet cuts them every time it passes, but it only cuts them superficially, maybe like 1/4" of their 3" height.

I don't know what's so hard to imagine about a manufacturer being able to easily and quickly replace something that is literally the most basic part to manufacture instead of having another manufacturer make it and ship it to them. Not to mention the down time costs on waiting for a basic part.

Jabor posted:Woe be on the new guy who puts regular swarf in the brass skip. Do large metal recyclers have a ‘mixed metal’ input option where they granulise everything then use froth floatation to seperate by density? You’d end up with seperate bins of iron, aluminium, brass and nonmetal. Different grades of stainless would be impossible to seperate though, and I assume there’s a large difference in value.

Jabor posted:Woe be on the new guy who puts regular swarf in the brass skip. Yeah, that's a few thousand dollars he just hosed up. Mix the metals and the recycler gives you the 'pity penny a pound' rates for it. His supervisor is gonna make him hand winnow that swarf until it gleams golden with coppery goodness. Pray he dumped steel chips in it, then at least he can use a magnet. The Lone Badger posted:Do large metal recyclers have a ‘mixed metal’ input option where they granulise everything then use froth floatation to seperate by density? You’d end up with seperate bins of iron, aluminium, brass and nonmetal. They do, but they generally give you like 5-15% of the value compared to three bins of pure-enough product. I don't know of any recycler that actually treats the incoming metals like ore and does the entire ball mill -> wash plant -> foundry process though.

Bubblyblubber posted:gently caress u zedprime i'll cnc a whole dang house if i want In about 2008 I was doing IT support for a guy whose business was custom staircases. He had a set of parametric scripts and custom tools in Autodesk Inventor that he could simply put in the basic of the bottom and top positions, optional landings, turns, styles etc. It would generate the entire thing, every bit of joinery, export a full BOM spreadsheet, and all the necessary CAM files for the huge CNC router at their workshop. He just emailed it all in a zip to the boys and a few days later the whole thing was cut packed and shipped. I don't know how much he turned over a year but he lived on a road called Grand Maison Road. His house was the Grand Maison.

Maybe a 95% saving in his hours, and like a week of man hours cutting all the joints, even with specialised morticing tools etc. it all hinges on him getting very accurate positional data for the stairwell. QA was greatly improved through the spreadsheet checklist so they basically never delivered a stair set to site missing pieces etc. Dude was an efficiency genius and smoked like a chimney. One of my jobs was reworking his iMac to boot solely from windows, and slightly modifying the internals to isolate the screen from the internal airflow because the screen was getting nicotine stains under the glass.

Ok, fine, drove over there with a box of random CPU fans in the hopes one of them would work well enough to get his poo poo working again. Open the case of the PC and found out why the fan stopped working... It was so gummed up with tar mixed with dust it stopped spinning. Cleaned all the tar out of the fan and it once again worked great. I thought I was going to puke.

zedprime posted:Other way around. I'm under the impression economies of scale often allow standardized parts to be produced cheap enough to pay for shipping and storing over on site fab because they can either minimize waste or sell/recycle fab waste easier ex. they don't have the mixed waste stream problem the one poster is talking about. Tying up your cutter making repair parts for itself can cost you orders of magnitude more in lost production than buying the parts from the factory, too.

I am no construction expert and can't judge whether one of these two has been more reckless than the other, can anyone who knows both cases compare?

Also he basically overbuilt the bunker by his own admission, and then after years and years of maintaining the bunker he started on the tunnel project.
