https://www.youtube.com/watch?v=_knFU0A9-hU I've tried to make internal gears by a number of methods in the past, but it's never quick, easy or reliable with normal hand or machine tools. The gear shaper is the perfect machine to do this, so I thought I'd have a go at building one. 
=== oxygen ===
https://www.youtube.com/watch?v=lB3hHk1_2V0 make An Oxikit-style Pressure Swing Adsorption Oxygen concentrator for cutting torch, medical usage out of air, $1300 in parts https://oxikit.com/ , https://www.nickpoole.me/ and code at https://github.com/NPoole/PSA_Oxygen_Concentrator 
- If you are going to use PVC pipe to store pressurized gas of any kind at any pressure, you MUST use pressure rated pipe and not "thinwall" or "DWV" pipe. I chose Schedule 40 pipe, which is the thinnest walled pipe that has a pressure rating, but there are such things as Schedule 80 and 120 pipe. Using pressure rated pipe does not make it safe to do, it just makes it safer. (Cheers, @Spirit532)
- Some concern has been raised about material fatigue caused by pressure cycling. I'm not convinced that a 30 psi pressure swing meets the threshold to cause this kind of failure, but the concern is probably well-founded. A failure of this kind at 30 psi could be scary, but probably not lethal. The chances are good that a failure would be unexciting, if it ever occurred. PVC is not a brittle material and is also very resistant to oxidative reactions. I will be sheathing my cannisters in something to prevent shrapnel just in case. (Cheers, @NicolasBana)
- Sieve is pronounced /sɪv/ and I know that in any other context (I pronounce it correctly in the idiom "leaks like a sieve") but I learned to pronounce "molecular sieve" from @NurdRage, for better or worse, and his incorrect pronunciation has stuck with me. (Cheers, @nilo70)
- My description of the PSA cycle is not entirely accurate. I state that the equalizing valve is mostly responsible for purging the nitrogen from one tank to another, but that's not exactly true. Most of the purge actually happens via the orifices in the output junction. The equalizing valve theoretically "primes" the unpressurized canister with the last bits of pressurized O2 from its counterpart (because the tank will adsorb nitrogen better under pressure, so if you already have some O2 pressure in there when you start pumping in air, you'll pass less nitrogen as the pressure ramps up) I may address this in a follow-up video, but this is still not a bad introduction to the PSA cycle. 
- Some of the PSA cycle diagrams show out of order, mostly when I cycle through them quickly. What I'm describing is still correct and any diagram that is discussed for any length of time is correct, it's just some of the quick ones. This section is a Google Slides stack that I recorded with a screen recorder and at times I advanced the slides in the wrong direction without noticing. 
- If it is working properly, the oil in an oil-filled pressure gauge will never contact the process gas. What I describe as a hazard is absolutely still true, however. Please do not use oil-filled gauges in oxygen service. In fact, if I were building this machine for someone else to operate, I would take apart the cheap pneumatic valves, wash them in degreaser, and re-oil them with a fluorinated oil for reactive gas service. Take care to look into the oxygen compatibility of anything that has to carry pressurized O2 (Cheers, @AdvancedTinkering)
- When describing the tool used to agitate the sieves in the OxiKit video, I call it a "pneumatic vibrator." In my head, they used a concrete vibrator. Watching the footage back, they're clearly using an air hammer. If you go looking for that tool, it's called an air hammer. I don't necessarily recommend using it for this, however. They make a point to run it at low pressure and to only contact the fittings with it and not the pipe wall directly, seems easy to damage your PVC this way. Buy a muscle massager instead, you deserve it.
- I describe the gas separation mechanism as "having to do with the relative size of the molecules" which is sometimes the case with molecular sieves but in this case, the mechanism is actually electrostatic and ion exchange interactions! This is why the metal cation (Li vs Na) bound to the zeolite affects the selectivity. (Cheers, @justliberty4072) 
=== diy hacks ===
A Cordless drill hack is to cut 17mm off the end of a 1/2″ x 20 UNF threaded keyed drill chuck and epoxy glue or JB weld it flush into the keyless chuck of the drill. The chuck doesn't have enough clamping force to prevent drill bits below 8mm from spinning in the chuck when drilling metal.

https://www.youtube.com/watch?v=u_F5OGjLpOQ meanwhile in the garage It's time to build something really complicated. This is kind of experimental video. I have a very old unrealized idea about an internal combustion engine, if be more correctly intake and exhaust system. Usually valves perform this function, in our case it is a camshaft with channels for passing gases. Ideas can be very logical and interesting on paper, but in practice it is very difficult to prove. So let's build a brand-new engine with never seen before intake and exhaust system and prove this idea. Whether it will work or not is a very big question. Let's find out. If this engine works as planned, then it can be built into any car or even build some kind of all-terrain vehicle. 
https://www.youtube.com/watch?v=V42RF7uS22s ,bandsaw, channel mrohny I have to hand it to you on cutting and bending the square tubing frame. Very good way of doing it. Well I spoke to soon. Now that I've seen the rest of the video the whole thing is very nice! Especially the coolant system. Most people don't put that on their builds but you went the extra mile. Good job!

http://www.abssac.co.uk/p/CURTIS+U+Joints/130/#.VbD44vkRG9c Uniquely, we can also supply the TakeApart ™ design which allows for dis-assembly and reassembly of the universal joint without the use of special tools and replacement of component parts. This feature enables the end user to machine the hubs to fit the mating shaft if a standard bore does not. In addition to this, easier access to other components in a drive line can be achieved by being able to quickly and easily disassemble the joint after it has been installed in the application.

https://archive.org/details/ECL-255 Peter Sawchuck is required to design a two-speed gear box for a cold rolling mill coiler. He undertakes the design of a one-off unit that will satisfy the requirements. The basic gear design is governed by AGMA specs, but the remaining components are governed by reliability and economic considerations.

The Engineering Case Program originated at Stanford University in 1964 with the support of the National Science Foundation. The catalog was maintained by Rose-Hulman Institute of Technology and Carleton University. It continues under the sponsorship of the Design in Engineering Education Division (DEED) of the ASEE.
