      I had read some reviews of that set that I bought and that was the common complaint. I sort of knew there was a high chance of breaking it but I just wanted to get through the surface hardness. If it had jammed in the hole I was going to be screwed but for once the broken off point did the right thing and flicked out of the hole.

    Your comments about “trade skill degrees “ is spot on … in the 60’s here in the states I was encouraged to go a technical high school (post Sputnik), and was told I couldn’t make it through college because the technical training was insufficient, in the 70’s educators actively opposed teaching skills because they “wanted more” for students i.e. a college degree. By 80’s the technical schools were gone and in the 90’s I had a number of engineers on my staff who disliked their profession and had a mountain of debt… I once asked an educator, several years my senior, why many educators think college is the only way to success and happiness … he said I think it’s because it is the only path they know and they don’t like getting their hands dirty

    • @Preso58
      @Preso58  20 วันที่ผ่านมา

      I agree. We ended up with a lot of students who fell in line with the policy of staying on to graduate in year 12 but in reality they couldn't cope with the higher level maths, science and English. Many became behaviour problems and essentially wasted two years which could have been spent learning a trade. Those that did finish year 12 but chose not to go on to university then had to find employment but often their attitude worked against them. We, as teachers. were often told by employer groups that they found older school graduates were more difficult to train, often turned up to work late or hung over and most had disrespectful attitudes towards their work colleagues. I always found that teaching year 10 students was easier than teaching older students (age 17,18) because they were still willing to listen and accept guidance. I have met up with many former students who went on to learn a trade and they generally did well and seemed to be happy with their choice.

    Hi Mark, the battle of trade school vs college is one that is being fought by Mike Rowe here in the states. He has been a champion of the trades for many years and is fortunate enough to have built up some notoriety and uses that to great advantage. I attended a trade school in my youth for the machine trades and even though that isn’t my current vocation I have used what I learned there in both my personal and professional lives.
    Thanks for videos and the continued education.

    • @Preso58
      @Preso58  17 วันที่ผ่านมา +1

      I have watched a few of Mike Rowe's videos on the importance of trade education. One in particular nearly bought me to tears. He is a passionate voice for the importance of balance in education and the recognition of different pathways to forming a career. My own son left school early to take advantage of an apprenticeship as a fitter/machinist. He finished his trade training early and then leveraged his qualification to get a job in New Zealand as a service technician in a company that sold and maintained industrial air blowers and ventilators. He jumped again to become the team leader at a semi government research and technology company in Wellington. I always maintained that a trade qualification is a stepping stone to a quality career without the burden of a student loan and subsequent debt.

      I am leaning towards a more industrial look for this engine. I have some nice grey and sage green powdercoat. Back when I had steady hands I used to add "lining" to my engines with an old school drafting ink pen. I still have it actually but my poor old shaky hands would never make it work now. I used to refer to cladding as the wooden slats which were often clamped on the outside of boilers and engine cylinders. Cleading however always refers to sheet metal over the insulation material. I used to work at the Brisbane Maritime Museum as a volunteer back in the late 1970's and they had a warehouse full of formed asbestos insulation sitting on high shelves. It was left over from the days of marine steam plants and it was sitting there awaiting disposal. The thing I remember was looking up at the particles of asbestos glittering in the sunlight coming through the overhead skylights. How times have changed!

I recently had to have a root canal procedure and I asked about the files and drills they used and they gladly showed me. The little files are finer than a strand of hair and they can curve around and follow the nerve cavity in the tooth. At the same time I was given the little dental burrs I was also given three dental picks and probes. They are wonderful tools and super tough. The quality of the steel is exceptional.

As it turns out, the Dremel I am using now is the third I have owned. The first one ingested a piece of steel scrap and blew up spectacularly while I was using it and the second one had a failed speed controller unit. This third one had better last!

      Thanks. Despite the multiple problems with that 3D printed eccentric strap and rod, it really does look great and it satisfied my curiosity about 3D printed metal parts. I have a model turbojet engine that is currently awaiting some remedial work due to a hot start distorting the nozzle guide vane assembly. I made it from two stainless steel parts that were tig welded together. It was not the best way to do it because the assembly is prone to distortion due to uneven heating. I am considering having the part printed as one piece. The great thing about 3D printing the part is that the complexity of the part doesn't increase the cost. It's only the volume of metal that sets the price of the finished part.

Do I sound bitter?

Towards the end of my teaching career, all year 12 students were sent to special classes so that they could fill out their tertiary education applications. There was no mention of alternative career pathways or if they were mentioned at all it was as if apprenticeships were a fall back position just in case you didn't make it into uni.

    Most impressive! I built one of these, like many did, some years ago, but without the improvements you added. One thing I wished I had looked into was adding some sort of counterweights to the crank shaft or flywheel. These engines can really bounce around on a table. What I also found was that the public only sees the engine's cosmetics, not so much the workmanship. Importantly a beautifully dressed up engine can be very inspiring to lure students into the field. Some inspiration may be found in looking at how the Victorian steam engines were dressed up. Thanks for the video. Cheers.

      These little engines really do run at non scale speed. I am hoping to build something like a dynamo for it to run so it can operate at a lower RPM. Just turning down the air pressure doesn't really work so well since at either end of the stroke you are just relying on the momentum in the flywheel to keep it running and with such little mass in the rim of the flywheel it still runs a bit choppy.

    Once again a perfect candidate for EDM plunge tool. If you have any small knowledge and practise with electronic bits an pieces, it is a fairly easy thing to make. I suspect most small stick welders use transistorised power supplies at reasonable frequencies, ie 10-20 Khz. This is more than suitable for plunge edm use, next is a device to raise and lower electrode into work, this can be easily done with off the shelf stepper motors and drivers, the mechanical part you can make easily. The only tricky part is to control the power requirements via sensing over and under voltage/current, which triggers the up and down motion of tool, and possibly shutdown current in device. All of this stuff is off the shelf today.

      I was able to visit the "Melbourne University" back in about 2006 and I was surprised that it turned out to be a trade school. We used to spend a lot of time talking to employer groups and they were resentful that they were getting fewer and fewer apprentice applications from year 10 graduates. They all complained that apprentice applicants from year 12 were less likely to turn up on time, often arrived for work hung over and had "know it all" attitudes. Like all social experiments, the push to boost retention rates had unexpected consequences.

      I knew it was a high risk procedure and I fully expected that I would end up breaking a few bits. Getting it jammed in the hole was my biggest fear though.

    I like brass lagging. I can’t wait to see what colours you paint it all. Very nice work.

    • @Preso58
      @Preso58  21 วันที่ผ่านมา

      I was considering some sort of classic colour scheme like Maroon or Royal Blue but I am now leaning towards a more industrial look like Machinery Grey or a dull Sage Green.

    I felt the pain of the broken bit.
    I dropped my centre rest and broke the hinge. No problem, braze it and re-drill the hinge pin hole . The drill sank through the braze and broke when it hit the cast iron. The brazing had hardened it.
    Used a carbide end mill and drilled out the twist drill, then broke the end mill at the same point! Luckily it fragmented and I was able to blow the fragments out. Second carbide end mill and very gently got past the transition.
    15 minute job took half a day and lots of frustration.

    Curtis is a great example what can be achieved with hard work and constant mind set. He goes from strength to strength and is a master of welding. Mark where would you go for fixed reamers for hobby metal working.

    • @Preso58
      @Preso58  20 วันที่ผ่านมา

      I just bought a set of imperial machine reamers from CTC tools www.ctctools.biz/hss-reamers/
      They are based in Hong Kong but the quality of the tools seems to be very good. I have purchased reamers from random eBay sellers before and it's a bit hit and miss in terms of accuracy and overall quality but CTC seems to be uniformly good and the shipping costs are reasonable. The last purchase I made turned up in about two weeks.

      I bought that on eBay about five years ago. There are no manufacturers marks on it but I think it is German. It's a nice unit and very heavy.

    Hi Mark. Great Vids.
    Just wondered if anyone out there, who's just got a simple cheap lathe and no milling machine with no DRO etc, knows the old school way of using a face plate, verticle slide, "keats" angle plate etc, to machine bores or other features etc...Would be interested to hear your comments! Cheers.

    • @Preso58
      @Preso58  20 วันที่ผ่านมา

      I have all those things because I started out having to use a medium sized Hercus lathe (copy of the South Bend). It wasn't my lathe but it belonged to the school where I used to work. I would go in on the weekend and do all my hobby machining then. No DRO and very little tooling. I used a standard Mitutoyo vernier (not digital) and I ground all my own tools from HSS. Having had that experience made me understand backlash in lead screws and how to compensate for it and using HSS tools made me appreciate feeds and speeds and what you can and cannot cut in that way. It is just my opinion but I think that most hobby machinists probably start out with the bare minimum of equipment and gradually acquire more accurate and more expensive tooling and accessories.

    Hi, did you use gaskets/joints between the cyclinder housing and end plates and the steam chest? These can add the slightest extra clearance for the piston etc so that it can be better adjusted to not make contact at either end of the stroke. My Stuart D10V came with the gaskets pre-cut.

    • @Preso58
      @Preso58  21 วันที่ผ่านมา

      There was a set of pre-cut but very thin gaskets in the kit. These may not survive the rebuild but I have some thicker gasket stock for the second assembly. I think the issue is the gland nut on the cylinder cover. It seemed to be a bit tight in certain orientations and the thread is probably not concentric with the end cover. I may have to re-make it and single point the thread. Which is a pain!

    It's annoying when the engine runs stiff after all that work. I had the same thing years ago but it was much worse than yours as I had to machine 3 thou out of the cylinder and all was good after that but it took me almost all day to find the fault. I still could not find why because I machined all the parts to dimension.

    • @Preso58
      @Preso58  20 วันที่ผ่านมา

      Yes, it's frustrating. I thought I was doing really well up until the time I started to fit the cylinder to the rest of the engine. I think the issue is a lack of concentricity in the piston rod gland. I cut the threads with a die and I should have single point threaded them while they were in the chuck. I may have to bore the hole in the gland a bit bigger. It goes against my instincts to oversize such a hole but the gland packing will take up around the piston rod and it won't leak but it still seems like a cop out.

      Mark

    Not everybody is cut out for Uni, but by the time they discover this it's too late to switch to a trade. It's been made too difficult/expensive for a tradesman to take on a 16 yo apprentice, so a 20yo has no hope. The end result is we have to import trades...

    • @Preso58
      @Preso58  20 วันที่ผ่านมา

      The biggest hurdle for kids starting a trade young is the lack of public transport, especially where I live. In capital cities it's not as difficult but if a 15 or 16 year old can't get to the job site it's always going to be hard for the first couple of years. I was told by some employers that they preferred younger apprentice applicants because they could train them the way they wanted.

    I tried throughout my 25 year teaching career to convince my "superiors" the value of industrial technical education. I was deemed a "dinosaur" and retired. Tired.

    • @Preso58
      @Preso58  17 วันที่ผ่านมา +1

      The irony was that towards the end of my career, the board subjects of Senior Graphics and Industrial Technology and Design were abandoned and we were forced to teach VET subjects like Furnishing, Construction and Engineering. "Engineering" was really just a certificate one course in machining and fabrication. It should have been a perfect introduction to the trades but it was so dumbed down that there was no incentive to create high quality work. The assessment was deemed to be either competent or not competent but there was no grading so many students just did the bare minimum in order to attain their competencies. I felt sorry for the kids who went out of their way to make a finely crafted project only to be told they were "competent". Although it wasn't required or recorded I would still give them a grade on a 15 point scale. It was worth it to tell them, "Yes, you are competent but I would still grade that as an A+." That always put a smile on their faces.

      Mark

    So true about about uni, if evefybody has a degree it undermines the value of a degree, which supposed to show a superior education, not an average one.
    It also reminds me of the old witticism, that a degree will get you a decent job, working for a boss who hasn't got one!
