Thanks! Probably about 5-10 minutes per wedge with the heat constant moving. The timing depends but typically when I start seeing the chrome turn golden, you are pretty much about to enter purple/blue time. Just need to be mindful to not go too crazy since it'll just turn dark brown. Kind of like a steak, it's going to keep cooking after you are done so I get to about 85% and then let it cool.



Edit: A good tip I picked up prior to doing this to a few clubs was using a MAPP gas torch since it burns hottest:

A torch is better for this because a soldering iron concentrates the heat in a very very small area. And since metal is so conductive and has a high thermal mass, it looses heat faster than you can apply it with a soldering iron, so it will never get hot enough to actually solder. Flux comes in a paste (or sometimes liquid) and is a weak acid that etches the metal to clean and roughen the surface so the solder wets to the metal and bonds better. It also helps keep air out of the connection to prevent oxidation while you're soldering, which would weaken the joint.

The steps would be to clean each piece, position or clamp them together, apply a good amount of flux, heat it all up with the torch, then touch the solder to the hot metal so that it melts on. If you need to apply heat directly to the solder (ie, the solder doesn't melt on its own when it touches the metal) then your metal isn't hot enough and it will make a cold solder connection that will be weak, or completely non-existent if it's too cold. It may look like it joined things, but the smallest bit of force (even from just normal handling) would break the joint and you would need to start all over by first cleaning off all the solder, then cleaning the metal, applying flux, and trying again.

Here's the torch I use:

Optional extension hose so you don't have to hold the cylinder the whole time

Solder and flux. This kit comes with some emery cloth to clean the metal a bit before soldering.


EDIT: Here's a video about soldering copper pipe. Same process for small sheet metal parts.

brass pencil flame torch + propane tank might be cheaper than a creme brulee torch + you can do dabs with it

Basic components of a pressurized CO2 system:

• Regulator -controls flow of CO2 gas into your aquarium
  
  
• CO2 tank - consistent, pressurized source of CO2
  
  
• Diffuser - breaks down CO2 gas into teeny tiny bubbles for plants to use
  
  Regulators: there are many brands and components to a regulator. I recommend a regulator with a solenoid, and a bubble counter. The solenoid allows you easily control your CO2 using an inexpensive timer, or an expensive pH controller. A bubble counter is a simple way to guess how much CO2 gas is in your aquarium. You may want to shoot for 3-4 bubbles per second depending on lighting and plants. I personally recommend the Milwaukee regulator and have used one reliably for years.
  
  CO2 tank: A 10 lb tank might last you 3-4 months before needing refilled. You can get a 20lb but they are huge and ridiculously heavy. On my 29gal, a 10lb tank lasts 6 months. Tanks ship empty and you have to find a local source to fill it with CO2. Try welding supply or home brew beer supply. You will need disposable seals too.
  
  Diffuser: This is where you have a lot of options. Ceramic diffusers are effective on small-medium tanks. CO2 reactors and DYI options using your filtration system are effective on a large size tank. I can't give any recommendations on these 2 options, sorry, hopefully someone will chime in.
  
  Other important equipment includes CO2-safe tubing, a drop checker, maybe a brass check valve if needed, and the aforementioned timer. Hit me up if you would like recommendations for these items.
  

The hose I have is 5'. I already had the tank, but that's the link for one if you need it. If you have a larger camp, you may need a 5gal tank.

(Links are not an endorsement, they provide a photo and may help you find the product locally. Some little bitch on this sub had a meltdown over that because she wanted to fix the issue today, and wanted to know what to buy locally. Apparently showing her a picture of what the product looked like so she could pick it up at the local bigbox hardware store is a crime against humanity.)

Q:How does one hook up a 20# just for use on a 2 burner Coleman stove?

• If needed, get an adapter to convert your old school white gas stove to propane. photo Using a propane adapter for a white gas stove really makes the stove a joy to use. But Coleman and others make propane only stoves, and you probably have that. White gas is pretty expensive now.
  
• Get a Bulk tank to disposable tank hose/adapter. photo
  
• If storing or using the gear inside a vehicle, I highly suggest a propane locker for the bulk tank. The locker is made so any leaks vent outside instead of into the living area. These are a fixture of full sized RVs. Trailer RVs usually mount the tanks outside too. Many people don't bother, but I'm worth it. Yes, I know a 20# BBQ tank locker takes up quite a bit of space.
  
  If you only use the propane for your stove and have a home base, you can get buy with a much smaller, approved refillable tank. photo The problem with full-timing with this is you can't use the propane exchange cages located at nearly every gas station, walmart, and hardware store. You must get it refilled in person or refill it yourself. (You will also go through the tiny tank quickly if you're heating your van)
  
  I have a home base, and my current setup is a tiny space. I use refilled disposable bottled propane for the stove and space heating. I keep the bulk tank at home. The heater is no longer sold but it's equivalent to the smallest buddy heater. photo I run it for 10 minutes before going to sleep or getting out of the sleeping bag, and for this use it's all I need. But then again I'm not trying to live like this full time.
  
  Q: Can you hook up a hot water heater to the 20# and not have to use electric?
  
  Maybe? I boil water in a pot and use an adapted weed sprayer to shower with. But I'm not full time.
  
  It seems hugely inconvenient to carry around a big propane canister just to lug it outside for my stove every morning, but the cost may be worth it, then?
  
  Yep. I cook on the tailgate when the weather is good. Like I said I refill the disposables before the trip and save a $1.50 each time. Might not be worth it to you.
  
  *I would never fill something like that on my own. Not gonna fuk with propane and blow myself up.**
  
  It requires some care, but it's easy. You just weigh the bottle when empty and write the weight of the tank itself on it with a black magic marker. When the tank is full, just make sure the total weight, minus the tare is less than 1 pound (or less than 12 ounces on some disposable cylinders.) They're actually hard to overfill but you need an adapter and a kitchen scale.
  

They sell refillable 1 pound tanks.

It's only a 1 pound tank (http://www.amazon.com/Worthington-281149-1-Gallon-Cylinder-Prevention/dp/B000SKX63U). With drainage holes in the area around it in case of a leak. In the end, it will also be in its own box with direct drainage so that there's no chance of leaking into the rest of the van.

Rest of the stuff, can do. Thanks!

Ribeye. First I blowtorch it (with MAP propane). Then I put it in the steam oven at 130F for an hour or two. Then I blowtorch it a bit more, for good measure, and melt a little butter on it.

Even the map pro is okay since Mapp was discontinued since 2008? http://www.amazon.com/Ez-Flo-85354-Mapp-Fuel-Cylinder/dp/B00GA7ICPM/ref=sr_1_3?ie=UTF8&qid=1465186234&sr=8-3&keywords=mapp+gas

IDK but I found this tank on Amazon. Maybe there's a better one.

Oxygen tank

Next I'll figure out how I can get an oxygen tank filled locally and then find a tube and mask.

Here is one from Amazon

I probably wouldn't buy one on amazon as you can probably get them cheaper from a welding store near you.

Also to get them filled typically they just do exchanges at a welding supply, switching out your cylinder for a full one. Also why you should check your welding store first, to make sure they carry oxygen tanks that size.

For reference, where I am at least a full T sized cylinder (the very large welding cylinders) only cost $80 for the oxygen. For those large ones, you don't actually buy the cylinder and you rent them, typically for a dollar or so a day.

If you want a torch that will last you for years.
