An amazing characteristic of this channel is you never know what you are going to see in the next video. I come here every day to feed my never ending appetite for all things tinkering. I also enjoy the history and walk through places of interest videos. Thank you Rob.
That is mind-blowingly simple but I didn't know I needed to know that. Even the most knowledgeable people can sometimes learn the simplest things but even less people will be happy to share.
Very good Rob. I will use this at work and watch everybodies jaw drop. They thought it was just a tape measure! LOL
Today I learned you use the same word for the magnetic instrument to determine direction on Earth, and the geometric circle-drawing-instrument.
In Norwegian they are komass and passer respectively.
Have you been watching Tommy Silva on This Old House?
I recently watched a video in which he suggested that he can use anything he can get his hands on.
The beauty of the tape measure is that all you need to know is how big you want the circle.
Awesome tip!
Nothing negative, just wanted to point out that you will create a slight oval instead of a circle if your nail is not perpendicular to the surface you are marking.
Booooooooo ;)
@@thematsta01 Booooo who?
What an awesome tip!! Thank you so much for sharing!!!
Huh. Impressed. Never would've thought to try that. 👍👍👍
I really like the simplicity of this but if you read below and use these bits of info you can also use it for auto determining the diameter or radius of your circle's outline?
*subtract the radius of the nail by measuring the shaft with a caliper or something and divide by two
The tab has something to allow getting a zero point on it when pushing or pulling even though it has a thickness to it that defeats this if it were fixed and did not have the option to slide in and out, (and they actually take advantage of the physics of using the tab if it is pushed up against the inside of a corner, or caught on the edge of something and pulled on)
*Pulling on that tab as the pen is concerned extends it out so the inside is the zero point, so just measure the diameter of the pen, where it would be pressed up against that tab, and divide it by 2
Once you have the distance of the radius of the screw and the radius of the pen, you should be able to add that to the length you pull that tape measure out, and when you get done, and measure across your circle and have exactly what you expected or wished for, thus making sure you can get exact diameters too, like when calculating out one disc as a core and two discs to glue onto either side of that 1rst core discs so you have a pulley that will self center the belt and keep it from falling off during movement, (I am working on something like this with a fluid surface like bearings have, for a band saw blade so it won't damage them when abrading against it, to make a wood mill band saw that can cut up to 5 foot (about 1.524 meters) in diameter logs or be pulled back on the backstop and down on the front to allow cutting deep into a flatter item like say cutting plywood that is 8x4 foot (1.21m x 2.43m) sheets even if I have to rotate them around with out banging into the side (the bandsaw blade made for cutting metal is about 25mm wide and 6.09 meters long or 20 feet and looped has over a 6 foot diameter LOL) but yeah something that won't break down over even a long time unlike even a very lubricious tough plastic like delrin (teflon fibers embedded in nylon 6) or even just pure HDPE or teflon both which would be kinda pricy to get big enough pieces for a foot in diameter wheel or somewhere abouts that.) right now I am thinking needle bearing like set up of cut drill rod to make tiny or short cylinders of steel and 3 pieces of circular steel with the second one having a middle ring cut out of it and the outside backdrop one goes through that middle ring and into the wood that way the inner metal ring can slide around as well as the one with holes cut in it to trap the drill rod bearings (provided I can not find enough roller bearing rod from very large industrial angler bearings which I might already have some that came from big dump truck drive shaft components I believe) anyway this will allow it to freely move around while still making sure the bandsaw blade does not slide off the wood inner disc, even when it is being pushed on with the material it is being cut with. :)
Great technique! I can definitely use that one.
Ha .. I needed to do that a few months ago. I used a plank nailed it through and another nail just out and scratched it around. This is much smarter. Thanks ...
That's a great hack. I've used a trick I learned before the internet, where it is easy to draw and oval using two nails or tacks and a loop of string. The most fascinating hack I saw on u-tube was for drawing a parabolic curve. I love having knowledge at my fingertips. That is why this channel is so valuable. You always come up with the most creative ideas.
and for a bonus you have the center of the circle clearly marked with a hole from the nail ! Brilliant !
Awesome technique! Thanks for sharing!
Genius!!! Thanks so much!
Simple elegant. Neat trick.
Thanks for that, a great tip!
Great tip thank you very much appreciated
I learnt that tip when I was in my early 20's. Other ways are a bit of string with loops on either end, a strip of wood with holes drilled along it for variable sizes and a nail in the end sticking out both sides so you can apply pressure and not need to make a hole in the work piece.
Excellent, thanks.
👍 Great tip ! Thanks for sharing ! 👍
932 people just got smarter.
You dang right we did. Awesome sir. Freaking brilliant.
that same nail can be put through a hole on a bandsaw and help you cut that perfect circle too
ha! forgot that one... been a while since I used a band saw or any other saw truthfully
Awesome trick thanks
Saw a video of someone using that method to mow there lawn the other day.
works good if you ha a hub half or 3/4 the width of s mower deck and a rope tether, to wrap around the hub. Setting the mower harness so the mower pulls away from center slightly as it chugs along... of course taking out the leftover fiddly bits can get tedious depending on the lawn... fun never the less,
Great video.
That is really cool
yeah i thouht so when i saw it - so thought i would share it
If this video was highly helpful and informative for you, I highly suggest you keep all the safety devices that came with your table saw installed. Maybe even spring for a SawStop, especially if you work with your hands.
Are you going around in circles mate? Great idea.
Tips like this are on TikTok. Also could be done using a string.
Nice technique just remember a sharpie will negate a few millimetres.
Perfect timing will be using that one for my competition entry... need a big circle, or BAC (Big Ass CIrcle)! :)
awesome mate
This works even in larger, ask the guys who made the cropcircles😅
Cool
Was the programme called changing rooms by any chance 🤣 good tip tho 👌
yep - brit program chances are no one else gets it and talk a bout an awesome tip - i had never seen it - well worth a share
You forget add half the width of the nail. Still a good trick if the nail is straight. Check your nail with a square ;)
a square or the body of the tape measure, I can be lazy sometimes...
1:30mn craft
👍👍👍
: ) cool
for sure mate
Changing rooms 🤣
yep - thought i would share it - it was so awesome
Who knew?
Too simple!
