  1. I’d probably be more concerned about the first two ( Quality and support) and not be as driven by the last two because they are not product specific. Libraries store their designs as common format files. The xyz library as well as about a dozen other libraries that are available are open to everyone. You can have a totally different printer but still download the files for printing. Same with the cad software. There are a bunch of CAD programs available and they work independently of the printer type. Many are free and are often cutdown versions of the major industry ones. The slicer program - which converts the file made in the CAD program to one specific for that printer is the product specific one but seems to be fairly basic compared to the CAD program. Some printers will print files sliced on a range of slicer programs while some require their specific program. Roxy, I actually first looked at getting an xyz because of the scanning capability. The plan being if I hd something that broke I could scan it and reprint a new one without having to learn to use a CAD program. But in the end I went with a straight printer. I then got an app for my iPhone to scan stuff. But in the end I have never needed to scan anything so never actually done a print like that. Everything I’ve made I have CADed up myself because they inevitably end up being new designs.
  2. Like everything it depends on your budget. There literally is a printer for every budget from about $250 up to tens of $1000s with the general principle of “ you get what you pay for” applying. It’s an incredibly finicky pastime and the cheaper you go the more work you have to do to get successful prints and the more failures you get. The band of about $1000 to $1500 being the broadly “best bang for buck” for the home user. There are a gazzillion reviews on the internet both written and videos. When I bought mine I spent a bit of time researching and when asking the web for the list of the best printers you get a heap of “ my-top-ten” type reviews. In that price band mentioned the one brand that consistently was top of the heap was the Prusa. I haven’t had any experience of Enders but the reviews seem to consistently put it after Prusa. But they are in two different price bands so that is what you’d expect. Prusa seem to have have gained solid reputation for support. The big issue is that 3D printing is still in the realm of the tinkerer. There are no home level “ works out of the box every time forever with every type of filament”. No plug and play without learning the ropes type. And they are a bit like home built aircraft - always something loosening up, wearing out or failing and support is a big requirement.
  3. I think it’s “horses for courses!” There are some things that can be plastic and would be of the strength required. Especially if you are designing them yourself they can be redone over and over again till you get them just right. Cheap, easy and don’t need the well appointed workshop. Some of the output of a 3D printer can be made really schmicko with post- production vapour smoothing. Of course there’s some things that need to be metal and structurally sound but honestly once they get to that level I’ll buy aviation grade ones from Aircraft Spruce.
  4. I’ve got a Prusa Mark 3S that I got as a kit and have become a bit of a Maker-Nerd I guess. I’ve used it for some Jabiru based stuff but nothing structural or requiring absolute strength. Some are pretty basic due to my just learning. I just use TinkerCAD to design things and the Slicer program that comes with the printer to make the guide files that the printer itself needs. I have tried Fusion 360 CAD program but Fusion 360 is pretty intensive learning and requires a lot of getting used to. so I tend to just stay with TinkerCAD which is a simple free online CAD designed for school kids. It’s About my level! 🤣 So my list of bits: Dash bits - Instrument hole blanking plug Small plate to hold USB extension plug from the sky view. Clips to hold sun visor up when not in use. Headphone cradle for the control/battery box on my Light speed Zulus Camera mount for my 360 Fly “ball” camera on the vertical stabiliser. There’s not a lot of things I’ve made for the Jabiru specifically compared to other stuff in the workshop or round the house because I’ve been worried about structural strength. Some have to be heat resistant if they are going to be permanent in the cabin. ABS plastic has the highest melting temps of the simple, easy to use plastics and is used for some motor vehicle parts but I’ve seen some examples where even they have melted so I’ve been a bit careful. I’d be keen to see what other makers/jab owners/pilots have done and extend my experience.
  5. Yep. Usually they employ consultancy firms who have no skin in the game and who direct their findings toward the answer they know will be best accepted by government and this usually involves the answer that will cost the least in the beginning. In the end it’s often the most expensive because the cheapest one fails then there’s the cost of extracting the disaster then the cost of implementing the proper program that should have been done in the first place.
  6. Mmm. Far too complex for simple answers. In the 1980s (when I was a medical student) they didn’t really cut numbers. What they didn’t do was increase them in line with the rapid increase in population. At the same time they accepted dodgy advice that hospitals would be less needed as people got healthier in the new age of technology and they cut hospital bed numbers and dropped the number of positions for doctors in the hospitals. Then Too late, they realised they had to actually increase bed numbers but by then there was a shortage of doctors at all levels - but especially junior doctors because large numbers of junior doctors could not get jobs here and had left Australia and had gone overseas. ( particularly to Britain and Ireland because there was still the perception that to be seen as a serious contender for specialist training here you had to have been working in Britain for at least some time. The decisions about hospital bed and patient numbers and thus doctors numbers to treat them was due to a complex interaction with state governments Health departments ( who pay for hospitals and also who limit the numbers of jobs for doctors in those hospitals), Doctors Groups( the AMA and others (eg Doctors Reform Society in those days) specialist and GP colleges and consumer groups who all had varying inputs into attempting to predict future needs. ( I know there’s often theory that the AMA is in control of this but it’s just conspiracy theorists. The AMA is just a union and has less that 1/3 of doctors as members. I’ve never been a member and in my 20 person practice only 3 are members. They carry no power or capacity to enforce things against the people with the purse strings -(ie: the state government) . Their entire clout comes from presentation of statistically justifiable and rational opinion. If they talked rot the governments would pay them no heed as they have no say over more than 2/3 of doctors) and definitely not over hospital employed doctors who have to sign contracts dictating what they can and can’t say and do. It was the attempts to predict the future hospital and medical manpower needs that was a dismal failure. That’s also a couple books worth in its own right. Essentially the then lack of Australian junior doctors resulted in a huge influx of overseas trained doctors ( paradoxically mostly from Britain where the NHS was in disarray and where heaps of Australians were doing there what the poms were doing here!) Now it’s a free for all with just about every university has a medical school and there are as good as no limits on student numbers. Universities get their funding by having students on the roll call so they go to great lengths to make more places and keep them there till they get out the far end of the sausage machine. so now there’s a glut. A medical student having completed the uni training can’t just go into practice. They have to get a job in a hospital as an intern to be supervised through another minimum of a year before they can be registered. So if you can’t get an intern job. You are unemployed. Now there are no guarantees that a student will get a job when they graduate and the university gets their funding by getting these students through despite no job for them. In fact it’s now almost a guarantee that some intern doctors will miss out on a job when they graduate. Nearly a million $ of community money wasted on getting them through to go on the dole at the end. Its been like many human endeavours - a pendulum that swings first one end toward disaster then back to the middle and looking good to overshoot the other way to equal disaster. Hopefully the usual pattern will be followed and eventually it will settle somewhere in the middle. I just hope it’s soon because I’m getting to the age where I’m gonna need a better functioning health system and at present it’s pretty scary.
  7. There has never been any suggestion an aircraft which is currently rated at eg 600kg can increase its MTOW to 760 kg. It has always been suggested by CASA that only aircraft that already are too heavy by virtue of their existent MTOW that fell between 600 kg and 760 kg could be registered “at their current weight”. If an aircraft is designed and built and certified etc etc at a set weight then the suggestion has always been that that’s it. Fixed at that weight. Just as they also stipulated that an aircraft that was over 600 or 760 kg could not be artificially lowered, by throwing out seats, lowering tank size etc etc.
  8. Nope. CASA might. But “GA” is such a diverse group that you should not call anything by that epithet. Certified aircraft in GA need to have approved parts though they can be made by and approved by a LAME with appropriate qualifications. But GA experimental/Amateur built ( which is more appropriate comparison whenever you mention or think RAAus vs “GA” ) can have parts made by the builder.
  9. The audio I listened to was only 29 minutes long from “emergency emergency emergency” call to end of landing roll. I don’t think it was edited.
  10. Not quite kgw. Instructors/CPLs can now just have a class 2. But only if they are just instructing and/or cargo piloting. I don’t know whether the instructor in this case had a class 1 or a 2. Cos the reality is that most instructors actually are on their way up the food chain and do charters and other air work when they can so most have a need to keep a class 1. The only instructors with a class 2 will be the older ready to retire type guys who do a bit of instructing for some pocket money etc or to keep their Ma and Pa flight school going ( and we know they are now a rare breed due to all the CASA over-regulation. Sadly CASA won’t let this faze them. What’s the bet they use this as argument to ramp up medicals.
  11. I have never really seen any loosening of any regulation by CASA which didn’t come with some strings attached which negated much of the lauded change.
  12. Somehow a long winded reply from me disappeared into the ether and I won’t have time to repeat it all but the crux was: The NDIS is $3billion underfunded in forward estimates and is being narrowed in its scope to deal with the unexpected huge take up. Theres no big wad of money going anywhere for funding anything outside of the narrowing range of defined disability. It doesn’t cover middle duration potentially curable medical issues of the type that AF takes people to the cities for. Even Rehab for stroke is not something that is a one size fits all and highly specialised modern stroke rehab is by the same limitations I mentioned before limited to big cities. Sub-optimal broad treatment is like everything else ( shopping, banking and entertainment) something regional people accept if they want to maintain jobs and family in the regions.
  13. I read somewhere that CASA had said it was going to be open from ?19th August - the date was not a certain it just sticks in my mind. But haven’t heard or seen anything. Maybe a delay or maybe was never a date cast in stone. Or maybe like a lot of CASA releases was just a thought bubble that never went anywhere.
  14. I’ve been incommunicado for a few weeks. Interesting to see where this has thread has gone. Sorry to disappoint you though Turbs (and Tuncks) this issue of decentralised and limited specialists in regional areas is never going to change. There has been millions spent by health departments and specialist colleges to do it but has met with failure because: 1: you can’t train specialists in the regions because you need mentors there to teach them and you need caseload to learn on (which is not in the bush it’s in the cities) 2:you can’t them to move there once they’ve qualified because they now have kids in school and spouse in a job and they can’t just be uprooted. There’s no prospect of tertiary education for the kids and limited advancement in the speciality for the doctor. 3: there’s not enough caseload to have an income nor enough to keep up your skills as a specialist. 4: patients get poor ( out of date or inexperienced) care from a specialist who sees one case a year of some illness compared to the specialist in the city who sees 100 a year. The reality is that transfer systems from the regions to the cities for medical care are here to stay. ( I’m a specialist in a regional centre and a director of a specialist department and spend significant amount of time trying to get specialists to come here to work and it’s often impossible)
  15. At one stage Bankstown had a fee for pushing an aircraft out of the hangar and another to push it back in. they bundled those under “movement fee”. Normal people defined aircraft movements as being under their own power, taxying etc. but the owners considered any time the aircraft was moving, even being pushed through the door as a movement.
