Just thought I should drop a tip for cutting tubing. A plumbers pipe cutter, it's made to cut copper tubing but also works for brass, bronze, and aluminum without a problem.

@vizionthing 2 года назад

And you can put the tube on a suitable drill shank to avoid making that lip

@NickSchade 2 года назад

I use the same on small diameter stainless steel tubing. Note that a pipe cutter will still leave a burr inside that you may need to clean up.

@Crazy5711 2 года назад

Be careful not to deform the tube when using a pipe cutter.

@tweedrhino 2 года назад

Pipe cutter will leave a small collapsed area around the tube making it so the pipe won’t fit. I’d suggest cutting the brass tube with the aluminum rod inside, which will reduce collapsing and burrs and removing the aluminum rod will use the burrs.

@gorak9000 2 года назад

I would cut off a piece that's too long with a hacksaw, so as to not deform the tubing, then clean it up on a belt sander to both remove the burrs and get the length correct. Setup a fence on the belt sander table that's perpendicular to the belt, and away you go. Just slide the tubing against the fence and into the belt and take off as much as you need. Of course if you have a lathe, that would be better, but I suspect he doesn't have a lathe, otherwise that would be option #1 from the beginning

@wildfire405 2 года назад

In all my years of physical science classes and tooling around my work shop, I have never had gears, pulleys and see-saws compared so beautifully to torque and power. I knew all this stuff, but THANKS to this video and your explanation, I now FEEL the science and the math meshing in my brain.You turned it into intuition. I am not an engineer, but am a high school design teacher. I've shared your videos with my students before, but THIS one is one of your greats. THANK YOU Mr. Fielding!

@deankay4434 Год назад

@wildfire405 > Years ago after nasty lumbar fusions, they stuck me teaching at UTI after years of fixing vehicles. I knew one concept requires three ways to explain it. We started with automatics & torque converters. We did the normal fan pointed at fan, then they lost it a torque multiplication. I told them say I have a 5lb steel ball on a 5 foot chain and swung it overhead and hit your hand. It would hurt? Yes. Ok, now the chain is 10 foot long swinging at the same speed! Now it hurts, but how much more? The few that had a hard time understanding how turning the fluid and redirecting it made more torque, now got it. Just like Jeremy’s teeter-totter example. It take different explanations for some to get it!

I was taught a screw became a bolt when a nut was applied. Some screws never become bolts. Great content as always!

@SianaGearz 2 года назад

What if the nut is captive?

@quintessenceSL 2 года назад

I thought a screw can create its own threads in an object while a bolt will go into already created threads (discounting fastening and unfastening into the same piece). Alternatively, whenever I search for a fastener online, the common nomenclature will be opposite of what I think it is (I swear half the battle in finding something is just figuring out what it's called).

@SianaGearz 2 года назад

@@quintessenceSL Isn't that a special case - self-tapping screw? As opposed to machine screw that goes into a cut metal thread?

@quintessenceSL 2 года назад

@@SianaGearz Most machine screws I would consider bolts (you need to cut threads for them, either by tapping or a nut). Consider holding two pieces of wood together. The difference between screw and bolt are pretty obvious then. My point being it shouldn't matter what you are fastening. It is in how it functions. Hence my confusion in trying to find fasteners online.

@RudyLib926 2 года назад

@wade reed I love that definition. I usually look at the end too, screws are pointed and bolts are flat for the exact reason you say. But I don’t think a screw should ever become a bolt, it’s designed to be driven in verses threaded into a nut 🔩

5 minutes in and I'm thinking a multi-speed bicycle would be a great visual aid for this. The arm (length from axis to pedal) remains a constant. As the gearing changes. The force required to move the arms increases or decreases, while the resulting speed increases or decreases depending on the gear ratios.

When you went from talking about levers to talking about pulleys, I began to understand how the block & tackle can increase the mechanical advantage. A pulley might be considered an infinite series of levers, the fulcrum being the center shaft. The two sides 90° from the "fully enroped" or "fully belted" end are where the work exchange happens, or opposing ends of the "lever". Thank you kindly!

@pedobob863 2 года назад

As everyone in the comments are saying, that was an amazingly intuitive explanation of gears.

Regarding screws v bolts, there is a podcast called Engineering Commons that came to a conclusion that screws are intended to thread into a material, and bolts are intended to be attached to a material via a nut. I have always liked their determination as it is dependent upon the use case.

I always thought screws are the ones that need a screw driver (Philips head or flat head) and a bolt has a hex head or some other shape and you would use a wrench or a key to turn it

@gorak9000 2 года назад

Yeah, but there are socket head cap _screws_ that take an allan wrench. And if you say "screws are pointy and self-starting", then the counter example is machine screws and lag bolts. The only conclusion is the actual problem lies with the English language, yet again.

@alans1816 2 года назад

You are an inspiration, and a demonstration that talent, determination, and work will get you to amazing places. It is useful to note that for most people a standard education is an easier way to get there. Bolts and screws are interesting. The most common screw has wood threads (sharp to bite into unthreaded softer material or sheet stock) and a head with a recess (slot, square, hex, torx..) to drive it. The most common type of bolt has threads designed to mate with a pre threaded metal nut, and has a (usually hex) head driven from the outside. The head seems to have priority, in that a machine screw has bolt-like threads but a recess in the head. A lag bolt has wood threads but an outside driven head. So my impression without looking it up is that the driving recess in the head makes a screw, while the outside driven head makes it a bolt.

@bobvines00 2 года назад

I was taught that (machine) screws thread into a threaded hole while bolts are tightened with nuts (i.e., no threaded holes in the parts they fasten). I think I recently reread this in an Engineering text, but I can't guarantee that.

@alans1816 2 года назад

@@bobvines00 That sounds right. My suggestion was based on usage, but technical definitions are not always followed colloquially.

@chitlitlah 2 года назад

@@bobvines00 Ehh... I've bought machine screws (according to the box) recently and used some with tapped holes and some with nuts. What you say suggests these identical components from the same box can be either screws or bolts, depending on how they're used. That isn't necessarily wrong, but it sure would make things confusing if I had to go to the store and ask for a box of both screws and bolts that happen to be the same thing. I can also think of many examples where something is called a bolt even though it screws into a tapped hole. I don't think there is a precise definition of a screw compared to a bolt, but I think yours is pretty far removed from how people would usually determine which is which.

@bobvines00 2 года назад

@@chitlitlah Yes, machine screws can be used either way. If I remember correctly, the terms bolt and screw are often used depending on how they will be used, but I think there are "technical" differences between them that most folks don't need to bother with. Typically people don't use the "correct" terms, but since everyone makes the same "mistakes" (me too), they are able to easily procure what they need.

@GordieGii 2 года назад

@@bobvines00 Yes, the technical difference is which thing you turn to tighten it. You turn the screw or you turn the nut. Lag bolts are actually lag screws. Hex bolts are often used as machine screws. Carriage bolts are practically impossible to use as screws.

@numberpie 2 года назад

difference between a screw and a bolt is, screw is designed to be driven into a medium or across two mediums to create tension within, while a bolt is designed to be paired with a nut and washer to compress two mediums between the head of the bolt and the washer (or nut if no washer is used), via a pre drilled hole in the mediums. both have similar uses however the way they are put to use is how they are different. the easiest way to determine if something is a screw or a bolt is typically by looking at the hole its is going into, if the hole has threads then its most likely a screw. (also take this with a grain of salt, I was not there when the books were written.)

A tip for cutting the bushing material is to cut it whilst it’s over the pin material. In your case, slide the bushing material over the aluminium rod then cut it to size. You will possibly sacrifice some aluminium rod but it allows you to clamp the material and the cut will be cleaner.

@johncichon9499 2 года назад

Thanks for the video Sir! I enjoy your good skills of communication as well as your creative mind. Excellent to encourage newcomers along. One thought from my experience was that a press fitted bushing will reduce the ID of the bushing. To use this to my favor, a reamer or a barrel lap could be used to remove a small amount of material once the bushing is pressed in (so it's easier to hold it while reaming).

@JeremyFieldingSr 2 года назад

Yes it does... but you are talking about really tight fits on both sides at that point. I only needed enough interference to hold a very light weight part in wood. If I was designing a machine from steel parts, and needed to heat the part to press it in, we have a lot more to consider. :)
