"I don't often use my micrometer. It's more accurate than I can cope with" Haha I feel you.

[@Alkatross]

How do you feel about feelers?

[@deankay4434]

It is just a threaded screw with division’s of 25 notches on its belt. The only match is addition. If the barrel stops between two numbers, then “SWAG” it. (Sophisticated Wild Ass Guess). And feeler gauges fall into two classes; flat and stepped. While flat are common and obvious in description, the “Stepped” are my favorite for speed and accuracy. I bought my 3 sets from SnapOn but if setting cold valve lash to 0.010”, I have to find the one that is marked 0.090”-0.011”. This make a step that stops taking the feel out of feeler gauges, that’s how they got their name. My only recent discovery in the world of accuracy was a documentary about an engineer before the turn of the century who tool steel and compound, rubbing each together for weeks or months. Each became standards so flat that when dry, the stuck together. Sold as a set and in very high demand, they sold for thousands of dollars. Millions in todays value. It was the beginning of machine making accuracy for firearms. This would allow interchangeable parts. Smith & Wesson pulled a stunt at the worlds Fair in Paris in 1906 (Not sure as going by memory) but to show their firearm accuracy, he took 8 firearms hours was spent on by technicians & engineers who filed and fitted each part. Either Wesson or Smith was the salesman and put on a show for hundreds. He disassembled every part of all six guns, moved the parts at random, put them together and they fired accurately. It was a huge victory for sales. Even though years before “Machines” could reach that level of accuracy.

[@rchandraonline]

Tin is possibly confusing "accuracy" with "precision". Accuracy is adherence to a standard. Precision is how finely divided the measurement is. You can have something that is very precise, down to a hundredth of a millimeter, but it can be several millimeters off standard.

Tim, I’ve been meaning to message you for ages. I’m a long time fan of your work. Like you I have an interest in all things engineering, I’m a tinkerer, and I’m never happier than when I’m in my garage welding, soldering or generally making/breaking something. I’ve been a fan of your work since the “secret life of” series. I watched them on video over and over and over as a child, seeing you and Rex talk about and demonstrate how things work really struck a chord with me. I’ve re-watched the shows many times since, and recently with my children who also loved them. It’s fair to say you inspired at least two generations of my family! I did actually meet Rex back in about ‘97, as we were both competitors on robot wars series 2. He was a lovely guy, they say never meet your heroes, but Rex didn’t disappoint. I’m emailing you today to say thanks for your recent KZbin series documenting your experiences over your long career in engineering. I find the new videos fascinating and it’s fantastic that you’ve taken the time to detail the practical things you’ve learned over the years. I love the level of detail you go into, and your passion is evident. I hate to think of this sort of practical hands-on real world knowledge being lost. That’s all really, I’m a huge fan, love your work, thanks for everything you’ve contributed over the years. I for one really appreciate it. I’ve never actually made it over to Southwold pier to see your under the pier arcade, but hope to do so soon. I live in Bristol, so it’s a bit of a trek, but I will make the effort as I’m sure it’ll be worth it. Thanks again Tim, I’m 45 now, and have been watching your stuff for 30+ years and will continue to do so. We need more Tim Hunkins in the world if you ask me! :-) Just getting to see the different parts of your workshops is a treat. Thanks Dan

[@KenColangelo]

You are an inspiration and a breath of fresh air after all these years. Your videos are like catnip for tinkerers. Thank you, sir.

[@romandybala]

Thankyou so much for your videos. They are very interesting and informative. Today we are so technologically advanced but the basis of this technology is so little seen or understood.

[@sketchyandrew]

Tim is using this platform to the fullest of its potential. Truly brilliant

[@DB-thats-me]

You’ve probably been asked this before but…. Any chance of doing videos of you fair ground inventions. One contraption per video starting from your oldest to latest. I know some have had their own airing but, as someone who has followed you from childhood, (and given I live on the other side of the planet), I would love to see them ALL, sequentially, and in their finest glory. With, of course, your cometary to their secrets and hidden Easter eggs. Thanks for YEARS of entertainment.

[@glitchout0137]

I agree, I would enjoy that very much. Also agree with watching you for years. I'm from the US and finding your SLOM series occasionally on broadcast TV was always a joy. Thanks for years of info and enjoyment.

[@20chocsaday]

It might have been more controllable using a Bit and Brace. I don't have one so I have frequently drilled out the screw. Once the head is off the rest of the screws are usually mobile. Unfortunately, some nuts have been damaged. Obviously I was not careful enough every time. PS. I now have a cutting bit which works when turning in the opposite direction to a normal drill bit - but have had no occasion to use it.

In the 19th century, stove manufacturers were using carriage bolts and Russell and Burdsall, two Quackers in New York City began making nuts and bolts. The village was known as the capital and nuts and bolts, and the company claims to be the first large scale producer.

[@deankay4434]

Tim, as a certified automotive ASE* Master tech in the states, I am tremendously pleased with the presentation, examples, history and the teaching you provide. I was told that “Archimedes” invented the screw that was using to lift water. Also famous for levers and fulcrums but still as fascinating subject. I was riveted to my chair as I watched, as if to somehow bolt down unable to move. I have gravity but what would space travelers use to hold them with no gravity. Velcro I guess as their sleeping quarters are sleeping sacks held in place with the generic two part material we now call “Hook & Loop” fasteners. Another interesting screw extractor is made by Ridid Tool, but provides a shaft with fluted sides. A hole is drill, the fluted extractor is driven into the hole, then a nut slides over it with matching internal fluted or vertical raised areas and turned by hand to extract the broken bolt. The fluted extractors can be replaced but often kept by the technician like me, as a trophy or sorts. As you call it a “Poder”, in the states we call it a “Spud” wrench. Tapered on one end but fixed size “Spanner” commonly used in construction as I repaired TV and Telephone Relay towers from 100 feet to 1,375 feet. That was the tallest for me when much younger. Thanks very much! God bless the brain that never sleeps or gets tired of learning. (*ASE= Automotive Service Excellence, 8 categories of questions on a test. Pass all 8, they award you a “Master Level” award.)

[@FilosophicalPharmer]

Respectfully, I’ve never seen anyone use a nutsert or “pop rivet” thread gun. Frankly, I never knew they existed. That said, I’ve always installed nutserts by dropping the nutsert or “pop rivet” thread into the hole, running in a bolt and just keep thumb pressure down while tightening the bolt with an open end wrench. This method takes advantage of the inclined plane that makes screws and bolts as helpful as they are. It’s much easier than the rivet gun method, apparently as I’ve never grunted while installing a nutsert. ☺️👍🏼 Found your channel only today and I’ve enjoyed each of the videos I’ve seen so far!

[@mikeselectricstuff]

On the subject of self-tappers, you can also get self-drilling ones that have a drill-bit shape on the end to drill the initial hole.

[@johncoops6897]

There are self-tappers that create a standard metric thread by cutting like proper tap. Don't forget "thread-form" self tappers, which have a triangular shaped beginning section that actually rolls or "forms" the thread - those tend to deform the metal into a bulge at the back, which makes a longer threaded part. To make them grip much stronger in thin metals, you can start them using a roofing punch, which is kind of like a center punch but thinner. You belt that in instead of drilling, creating a divot that you then drive the self-trapper (of whatever form) into.

[@EndlessDelusion]

THANKS FOR YOUR VIDEO. I subbed. A friend of mine started working at a major heavy equipment building company and they were breaking these big 1 1/2 inch taps, very readily. He turned them on to using CRISCO VEGETABLE SHORTENING instead of a tapping fluid. They could, then, power-tap without breaking the tap. He turned me on to it, as well. I stopped using cutting oils for threading and tapping, all together. There's you a dandy piece of advice from one old machinist to another. Bill, from Tn. 🇺🇸
