This channel, my channel, is now almost 16 years old and when I originally started it airguns were the main theme. There are now over 80 videos on the channel and the bulk of them have to do with airguns, particularly scientific testing of airgun parts and materials and concepts. All of the content is mine, and in the past 16 years my interests have varied, but have always stayed with a scientific leaning. I have no intention of changing the name of the channel, and its content will continue to be about projects I am working on. If you go to the channel's home page will will find videos about airguns, and other interests, that you will not find anywhere else.

Great channel, very educational. I guess many are here because of the L2 failure last year that made news in airgunning community (the cause of which is unknown). A reminder of the danger of HPA.
@1227air500 2 ай бұрын
Thank you for the kind reply. I read a few of the anecdotal accounts of the L2, but as you implied, finding information that is adequate enough to do any type of failure analysis (guess) is almost impossible. My anecdotal information is related to interior features that were not adequately described and therefore might have lead to stress points. But I certainly do not know. What I did find in all of my own destructive testing was that any parts for which I calculated yield and UTS values based on actual part measurements and specified material always exceeded the calculated failure values. A part that is inadequately described (dimensioned) on a drawing has the potential for problems. Sometimes when model files are electronically exchanged without dimensioned drawings, areas that leave some subjectivity open to the manufacturer do occur. Lloyd

He's cutting the deck in the front to use it as a discharge number one also so that the brush has the ability to stand up momentarily prior to being chopped so it is getting pushed down by the front of the mower. A better design would be a front tilt deck mower and they're not that expensive they're pretty much out of favor and you can pick them up relatively inexpensive and by having a tilt front deck mower. You're going to have the ability to pivot the deck 1015 degrees as you enter the brush and let the blades chop it all up
@1227air500 7 ай бұрын
Cutting an inch or 2 would be fine but you don't want to weaken the deck too much. The way I changed the rods at the front of the deck to raise it up and effectively tilt the deck made it ride over the tall stuff fairly well. A brush guide inside the front wheels to keep the brush from hanging up in the steering tie rods is helpful. Also you don't want to cut so much off of the bottom edge of the front deck that you will ram the new cutting disks into a stump and break the blade spindles. Don't get too aggressive in the design right off the bat. See how the rig holds up for a while and then modify it some more.

The Manual clearly shows a Powerlet going in the shorter tube, with its snoot facing away from the gun! So the piercer (Part 5 in the manual) goes in first, THEN the powerlet. Now if you're holding the short steel tube and look into it, you should see the smooth round BUTT of the Powerlet. This also makes sense if you look at the threaded brass adapter, the end of it that screws into those tubes has a spherical recess in it that seems to fit the north end of the south bound Powerlet, so to speak. No need for a spacer! This isn't shown in the manual: If you want to use a single Sparklette (8gr chargers for seltzer siphon) I think it will work just fine, I hope to do it! THEN you'll need a spacer, it will go in the tube LAST and be .70" long I think. It could be machined from solid, I will try to make the spacer FROM used Powerlets, just for fun. Oooh, recycled! This could be done by careful hand work, or with a lathe or milling machine of course. I have one of these outfits now, and think the small 8gr charger should be ideal. Economical, common, high-purity food-grade CO2, and a good number of shots for a day.

The apex of this is the Crosman Silhouette pistol, which has an air-chuck ON the gun... the SCUBA tank has a fitting attached to it by an adapter. SO, I plug in the pistol, open the tank valve, close the tank valve, DONE! This FEG thing is such a gadget, with wrenches, machined brass parts, instruction book, it's a (retired) engineer's idea of a good time. I just got one and really want to see it go. It's very promising. I will never run out of CO2! I really want to try filling from a bulk tank at least once.
@leonardpearlman4017 10 ай бұрын
Ten minutes later: Upon more mature consideration and research: I actually got up and walked to another room, and looked at a CO2 tank and also a CO2 regulator that happened to be sitting there. I hope you all appreciate this! The large brass fitting here LOOKS like a CGA 320 fitting for a CO2 tank that's been cleverly made... That is it's a special part that fits the CO2 tank at one end, and your refillable cylinders at the other! It might be that this brass thing can stay on a big CO2 tank if you have a spare one. Ideally one with a "siphon tube" that feeds liquid from the bottom of the big tank. It's starting to look like everything you need to use bulk CO2 is in that case already! Looking again at a (picture of the) manual, this seems like somewhere north of fifty or sixty thousand shots, the fill locally is now about forty dollars?
@leonardpearlman4017 10 ай бұрын
??? Judging by THE MANUAL, it looks like the longer tank allows you to use smaller CO2 chargers. The common Sparklets, they hold 8 grams, and are used to make soda water in the famous siphon bottles. I've been looking into this lately b/c I want to buy one of these outfits. The 8g charger is shorter than the 12g one, and two of them fit in the longer tube nose to nose, with the piercing device between them. OR you can use bulk fill, but I don't quite see how this all attaches to a large CO2 bottle, which are quite common, and easy and economical to have filled. They are used in soda fountains and in welding, holding I think 20 pounds (9000 grams! 750 Powerlets or 1000 Sparklettes) of CO2. They might be the cheapest of all CO2 sources. I did some online shopping for CO2 adapters, and there are dozens of them! Watching this video for the third or fourth time I realize that the larger brass device might BE the big-tank adapter! It might be that our host has not read the manual. SO this system has the maximum variety of filling options: Big tank, 8gr chargers, 12gr chargers. As of today I find that the smaller chargers are cheaper per gram, it might be b/c they are very common, a kitchen supply you could say. I probably have a case of them already. Plus they are a handy size if you could use just one. This seems to need a home made spacer as we see in the video. I note with sad interest that the Crossman Skanaker outfit seems to have the best way to fill a cylinder from a bulk tank. Very positive and simple, no need for refrigerating anything, no question of being able to fill the cylinder. Unfortunately it ONLY works with bulk fill I think, which might have limited sales. I thought it was clever of FEG to make it possible to shoot with Sparklets. I looked at a box of these and they were made in Hungary! I'm sure there's a story there. Maybe they invented the process to MAKE the little CO2 bottles?

Thank you for this experiment. The 12g of air must have been very hot from the filling process in order for it to increase the temp of that massive metal block ~5F in just a few seconds, correct? Would be interesting to see the pellet speed drops after the gas dropped to room temp. Might take a while since air doesn't transfer heat too well. Might require a pressure gauge on the dump chamber to verify there were no slow leaks.
@1227air500 10 ай бұрын
Thank you for the interest and comment. Because there was a slow leak past the pellet, I had to fill the reservoir quickly so that there would be plenty of pressure for the shot. When the air leaves the fill hose and expands, it first immediately draws heat from metal reservoir, making the metal cool. But as it re-compresses inside the reservoir, it gives up heat to the metal, so the temperature of the metal quickly rises. This all takes place within just a few seconds; actually much faster than you would think. If the gas remained in the reservoir long enough for the temperature of the metal reservoir to cool back down, part of that heat would go into increasing the pressure of the gas (air) in the reservoir, and the rest of the heat would heat the air around the outside of the reservoir. You can think of it this way: the heat capacity (you might call it energy capacity) of the metal is just a change in the temperature of the metal. But for the gas, the heat capacity is both in the temperature of the gas and the pressure of the gas. And that depends mostly on how quickly the reservoir is filled. If you fill it slowly, the pressure will go up and the temperature will stay constant. But if you fill it quickly, the pressure will go up less, but the metal of the reservoir will get hotter. The total energy does not change, it just changes state. I demonstrated this (to myself) once when I quickly filled a long tubular reservoir that had a piece of synthetic material at the far end to act as a filter for when the air was allowed to exit. The entry end of the tube got very cold, but the far end of the tube, where the material was, got very hot, hot enough in fact, to char the synthetic material! I wasn't really expecting that, but it really drove the point home. If you think about it, it is very similar to the compression process in a diesel engine. Lloyd

You see nothing leaking or distorting and claiming that it's anti-climatic. That is true as long as nothing goes wrong during the test. If it does go wrong you got a real bomb on your hands at 10,000 PSI 😉 there's another thing that might be a bugaboo in the research and design of a new rifle at this pressure. The recoil may become hard to manage. Best guess the recoil's going to be somewhere around a 300 win mag. One thing is for sure if this is made into a practical rifle you can be shouldering a bad mama jama. That requires a whole new way of thinking.

Hi Gino, The test cylinder is filled with hydraulic oil and the oil is pressurized by an oil-over-air force multiplier. The oil and air are separated by a moveable piston, such that when/if the tube fails, the oil will escape but the air will remain contained in the pressure multiplier. The main purpose of the tests was to verify that the mechanical strength of the pressure tubes met or exceeded their mech specification. But what it also revealed was that the strength of the tube isn't normally a concern. Something else in the system (an o-ring for example) will fail first. Take a look at this later video and see ho the threads were starting to fail when the tube burst at 15,000 psi. Lloyd kzbin.info/www/bejne/ZqGuoZ2rZdiKjMk

Hello good sir..that is a very informative testing..i've watched your video where you thin down an airtube..i wonder if you can do a test on a faulty airtube threading..like a very wobbly connection between a the end cap and the airtube..just to clarify a good material doesn't really matter if it is not done properly..thank you sir
