Is there somewhere you can refill these handheld propane torches? There a infill nozzle on top. Also where do you even recycle these things?
>>1610846They aren't supposed to be refilled. It's their business model to get you to buy more metal, and they justify that by making it illegal to refill it, so no company in their right mind will refill that.You can probably build your own adapters from machined brass and refill that from a larger 20 lb bottle though. I'm not sure if the refill hole is closed shut (like a rivet) or if it is still usable…
>>1610848That's terrible for the environment
>>1610846Don't buy the bernzomatic ones, buy the 'camping' cylinders which are like 2/3rds the price normally.
>>1610846>>1610848I think the little nub on the right might just be a pressure relief valve, so that the excess pressure escapes instead of having the whole bottle rupture in a fiery disaster.So really, what you're looking for is an adapter that will fit the tank like the torch adapter will, then you connect it to your 20 lb bottle using a regulator and a valve, then you slowlyopen the valve until pressure is equalized.Make sure your torch and your bottle are for propane, as manyBernzomatic torches run on a butane mix.>>1610850Meh, people would rather not fuck around with old bottles andmanufacture dates and pay a little extra for a new canisterevery time. I am not aware of a store that will refund you whenyou bring your old canister, but any store that sells that shouldat least take it back free of charge.>>1610852They are certainly refillable, but I don't think you can fit a torch on these canisters… Different thread/size? Plus the format isnot the same, the Bernz are easier to hold.
some have a valve that won't allow them to be filled without a special tool
>>1610856Seems cost-prohibitive to have a built-in check valve if they are supposed to be disposable.
>>1610846this lil nigga there will do just finehttps://www.ebay.com/itm/Propane-Refill-Adapter-Lp-Gas-1-Lb-Cylinder-Tank-Coupler-Heater-Bottles-Coleman/121176095084
>>1610852I got the bernzomatic for like $3.5 at Walmart so maybe not, that's pretty cheap. Can you use Coleman like in your pic with a torchhead?
>>1610861>Can you use Coleman like in your pic with a torchhead?Yes. The fitting is the same - exactly the same.The Bernzomatic fits your hand better for holding as a torch.
>>1610854Our truck shop stocks the Coleman ones for torch purposes. They work just fine. We don't refill them, though.
>>1610859How do you figure when it's full. I rather not overpressureize these things?
>>1610857not really. if you successfully refill one chances are you're never gonna buy another so preventing you from filling is worth it
>>1610869well the 20lb cylinders are like 200psi. no idea what the little ones have. they do all have a relief valve for safety tho
>>1610869You can't overfill it under normal circumstances.You're more likely to get it only half full.If it is somehow over pressure (overfill, heat, etc) the tiny port with what looks like a tire valve is actually a pressure relief.A schrader presses IN to open the valve.The core in the bottle lifts UP against spring pressure to open.
>>1610861Yes. I have a torch like this so it doesn't matter what size the cylinder is since you just hold the torch head handle. Also the camping cylinders hold more fuel.
>>1610875>the 20lb cylinders are like 200psiit depends on the temperature, not the fill level
God damn what r the chances this would come up today. You need a unef 1"-20 fitting. You can get one that's called throw away or disposable. Get one with npts or a BBQ bottle fitting. You will get 90 percent of what's in the big bottle. Pressure differential. Cascaded to equalized. Now I don't know what's in the little bottles, or the big ones so that may be an issue. You could get a hose and run directly off a big bottle.
To dispose of the blue bottles and camp bottles, scrap yards will take them if they have holes cut in them. What I do is save them up, take them up to my back forty, line them up, light a campfire behind them and shoot them with my .223 with 175 grain from 100 yards. Sometimes, they launch a dozen feet or so, other times, nothing. You can refill them with the adapters from Amazon, but you have to have tubs of ice water to control the heat, turn the 20 pounder upside down (to send LP into the blue bottle, not gassified propane) and should have the adapter connected to a 5 psi BBQ regulator.It's a PITA and disposables are cheap. Plus it makes for good target practice so I'm ready when the Gub'ment tries to Molon Labe me cache.
>>1610880they use a chart when filling. X psi at X temperature. is the same thing with pretty much all gasses
>>1610895>scrap yards will take them if they have holes cut in themTrue, but because I live in a city I put a nozzle on the bottle, make sure the valve is full open and use a egg beater hand drill with a sharp bit.
>>1610908I live in Detroit (yes, the actual city, not a suburb). I drive my bottles 4 hours to Ranger Lake near Gaylord to shoot them. Last summer, 2 docs from Receiving Hospital came up with me and one brought a god damned Remington 700P sniper chambered in 7mm RemMag to shoot the bottles, sending them tumbling over the fire at about 10 yards behind it. We never found two of them.
>>1610880The 200 pound cylinders are designed to withstand the same pressure ranges as the handheld ones.
>>1610869You need to use a scale. Just guessing will cause someone to get hurt.
>>1610846>>1610848Ex-airshitter here. We used those to refill our gas-powered replicas because it was cheaper than buying green-gas. Some companies made refill adapters. Maybe there still are some on the market, might want to look on airsoft shit stores. On aliexpress, maybe? But I havent played in like, 10 years, so I don't know.
>>1610879You should try out the hoses. Makes it so much easier to get in tight spots with goofy angles if needed.
>>1610852how in the hell are you supposed to dispose of these?
>>1611286Bury em in the recycling bin
>>1611286I throw mine in the dumpster at work
I'd seen the 20lb to 1lb refill adapter at my local Walmart for $16. I've even, in a pinch, refilled my propane cylinder with butane. Chose the appropriately sized tip to snugly fit the butane tip directly into the outlet of the propane and it went in without fail. The butane through the propane torch tip has similar heat to the propane, I thought, and got the job done.
i took an old torchhead for the disposable bottles drilled and tapped the outlet to 1/8 NPT. then i took a standard propane to quarter inch NPT male fitting and used a 1/4 female to 1/8 male adapter into the torch headscrew together, open both bottles, flip the whole thing upside down. then pull open the relief to let gas out of the small bottle, this allows the liquid to draw in. you'll hear a gurgling. do so until about 70% full. this is the fastest way, but you can definitely fill them to 100% with liquid and thats a not good. 70% at most as once the bottles back up to room temp the liquid will turn to gas, and at 100% liquid theres no room so itll vent. dont be stupid and itll be safecheap as fuck too
>>1612461>The butane through the propane torch tip has similar heat to the propanenope
I have a cheap drill press and it locks up if I try to use even quite small (1/2 inch) spade bits with it. Motor just buzzes.Is this because crappy drill press, or because trying to do something a drill press shouldn't be used for?If it should work fine with a better press, I'll invest. But i don't want to waste money on the upgrade if I'm doing something that's wrong anyway...
>>1612479If you mean a dremel on a stand then that is normal and its shitIf you mean an actual drill but a baby bench one then either its fucked or you are feeding WAY too fast or doing something else retarded.
>>1612485It's an actual drill, but super cheap big-box starter unit. I doubt the unit is even 1/3 hp and the entire thing is built out of chinesium.
>>1612479im assuming you arent trying to drill metal with a spadea drill press should be the first thing put in a shop in most cases, extremely useful. get a good one
>>1612487>super cheap big-box starter unitThat's the problem. Those are remarkably shitty these days. Failing to run a half-inch spade bit (in wood, I would assume) is bad even for that level of quality, but it's not too surprising. If you want a decent drill press new, it will cost a few hundred dollars minimum, so it's probably worth looking for a used one on Craigslist or such. An old industrial drill is about the best to be had, but it's probably more than you need. If you can't find something good used, mid level chinesium can be perfectly usable. Just check reviews and be prepared to pay a lot more than for the bottom tier stuff. For perspective, I have never seen a drill press that's not bottom tier at a big box store.

I recently got offered a job as a welder helper.I know just about the surface information of the trade, no hands on experience though. What is a day to day life on the job for a helper? Is it hard? Just mainly grinding and cleaning the shop?
>>1613161Depends a lot on the specific work involved, but probably something along those lines. Generally, miscellaneous or low-skilled stuff. That could involve actual welding or fitting of simple non-code things, and a good shop will train you to be productive, but that comes down to the specific shop too. What does the place do?

>>1610846Refilling your own propane bottles is really easy to do, and it's crazy cost effective considering they're about $3 per bottle for the green ones. I use the green 1 pound bottles and refill them from a 20 pound tank with a food scale and an adapter I bought off Amazon. They weigh .13 lbs empty, so full they weigh 1.13 lbs. I connect the adapter to a 20 pound propane tank, flip it upside down, and then hook up a green 1 pound bottle to it. Open the nozzle on the 20lb propane tank and let the liquid flow in. Don't worry it takes a few minutes to get it pretty full. As it fills up it also pressurizes the 1 pound bottle which pretty much stops the flow. I take it off after a minute or so and stick a screw driver in the one pound bottle opening to bleed some of the pressure out, then I hook it back up and keep filling. Take it off every now and then to measure the weight, and when I read 1.13 lbs on the food scale I'm done. A 20 lbs tank is about $15 to $20 depending on where you get it. I usually pay about $16 at HEB for a 20lb tank refill, so I'm able to fill a one pound bottle for about $0.80 and plus I'm not throwing away empty bottles and causing more trash. It's really easy man, I highly recommend filling your own. Here's the link for the adapter -https://www.amazon.com/DozyAnt-Universal-Propane-Throwaway-Disposable/dp/B019CND6J2/ref=sr_1_2?keywords=propane+cylinder+refill&qid=1558317692&s=gateway&sr=8-2
>>1613716cont....pretty much looks like this. Flip the tank upside down so the liquid can flow into the green bottle.
How long would this take to mix by hand? 80lb bgsShould I just get a truck delivery?
>>1613724You're never gonna mix all that by hand. I helped a buddy build a fence and the only way we got through pouring all the concrete for the fence posts is because he rented a mixer. Those bags are hella heavy and we were dead by the time the day was over. We only carried like two at a time via a wagon from his front yard to his back yard and even that was exhausting dragging 160 lbs per load. At 80 bags... yeah I might look into just getting a truck delivery
>>1613724That's 7 pallets.
>>1613724i estimate it would take about 16 hours of non stop mixingprobably about 3 days in reality, because youre going to have to take breaks for food/water/sleep.go buy a couple bags and mix them by hand and if you are still even considering doing the rest, give it a shot
>>1610869im not a sci-tard but the same physics that allow you to refill a jet lighter from a gas canister would save you in this circumstance? they both clearly have different capacities (like 1ml vs 500ml). im sure theres something like gas is only under pressure in different atmospheres, eg, theres no 'pressure' when filling an lpg tank since its not compressing, just transferring
>>1613730Just pour two bags in the post hole and add water and mix with a stick. Who gives a fuck what it's going to look like underground?
>>1613724>Should I just get a truck delivery?Yes. Are you doing a driveway?
>>1614636>and mix with a stickyou don't even have to mix it - just dump it in and pour water on it until there is a puddle on top
How do I disassemble and thoroughly clean and restore my Leatherman super tool? Imagine I live on the street and don't know shit, please, because I don't know what good chemicals or tools to use for the job.I also need to bend the Flathead back into good shape.

>>1614668Can you fuck off with your consumer identity bullshit? I'm here to learn.
>>1610850The steel propane minis are like $4 at Home Depot and Lowes, and are recycleable once empty. There are canned soups that cost more and have way less metal in the can. Plus, the bad effects such as a fire or gas explosion from a leaking bottle, or improper refill are way worse than just recycling hastle.
>>1614666Satan trips confirm that Leatherman are the devil.
