Rob, if you turn it upside down, you will get little to no powder out, when you squeeze the handle. This is the same way that refrigerant tanks are made.
Like to add,if you get Co2 extinguishers that are still full,these can be used for welding gas(MIG) just turn it upside down attach a Co2 regulator and weld away,it burns hotter than argon mix so ideal for thicker steel😉
As a pipefitter in my younger days, we used a large metal "saw horse" design with wheels mounted on each end in pairs similar to your set up in concept. The wheels were around 5-6" diameter and one had a geared motor with adjustable speed control so the speed could be adjusted for different diameters of pipe.. On a large order of duplicate pieces, I rigged a foot switch to the welder and mounted the "gun" on a pedestal in the proper place.....sure made welding pipe/flange seams easier. Great idea Luke!
Albert Einstein said, *“The definition of genius is taking the complex and making it simple.”* You sir, are a true genius. Love watching your videos. They inspire creativity and inventiveness.
I like the part where Robert says, while picking up a hammer, "I really don't care about this, I'm never going to use it..." 🙂 Useful, Robert, thank you. I remember some of it from when you first posted it, and now I have 3 expired fire extinguishers.
Nice cutting jig, and Luke's mk II pipe welding version is just genius. Nice one mate. I've a similar caster set up with a barrel on top with dry sharp sand in it for polishing my chain mail.
There are also fire extinguishers that use powdered glass. The powder is sprayed on the fire, the glass powder melts, covering the fire and snuffing out the fire.
My best supply of compressed air gadget base material ! If my pascal to bar math memory serves me right I recall those suckers specified good up to 17 bars. Tank batteries, condensers, collision/centrifugal separators, sand/chemical drop/suction feeders what have you. Your metal fabrication approach looks down and dirty typical english straight forward functionality with no OCD BS. Maybe a general class playlist serie on the topic could prove you a popular content to make ?
To the novice, that’s the wrong side of the grinder to be on! To the experienced creators, do your thing😉 I’ve used all sorts jigs and believe in using them most definitely! If you can’t build stuff nice, make stuff to help you👍
I use 4 extinguishers to inflate my boat tender. Look for the ones with the tyre nozzle valves. I use a compressor to pre charge them and horse them into the back of the car.
I push a small tube into the canister when emptying them to let air into it. It tends to get stuck when you turn them over. Most likely it creates a vacuum in the canister as the powder tries to rush out.
In your pump shown at 1:00. What happens if you have 3 or 4 of those on a ring with a heavy weight that is rotated around the ring. Much like a current variable displacement piston pump. Could that use significantly less energy than conventional centrifical pumps. How about moving massive quantities of water using a sealed tube archimedes screw. The entire spiral tube assembly rotates. The lower end on a floating barge so the tubes are never filled to the upper root diameter which would cause it to empty out. This could be used were 20 to 100 foot lifts of water are needed. Almost half the electrical energy used in california is used to move water around the state. That is a huge amount of power. One lift is just under 2,000 feet vertical to supply los angeles . 40,000 horse power electric motors do that.
you should make an air fed respirator. I can send you parts to 3d print if you want. everything just clips to your respirator, you'd just need to buy a small air pump for $20 and some cpap hoses.
I get out of date CO2 extinguishers to use with a regulator as almost free MIG welding gas. Once empty I've done various things with them, like cutting them in half, spraying the bottom half green, and using them as alloy plant pots.
Yet another in the long line of videos that show us how to do stuff practically! One note of caution ..... those weld flux fumes are seriously bad news, and the reason you don't see old ex-welders! Worse than Capstan Full Strength and Woodbines combined! ;o)
drag welding insnt the best if u had a basketball court full of leaves would u walk backward with a garden hose to wash it? nope - mig welding you push the nozzle in the same direction the wire is going so roll the f-e to you in this case
