Nice one Rob. In my career I have learned never to be intimidated or moved by persons who are quick to point out possible errors but have no solution themselves.
Great video, as always. Love the way you address both sides of the complaints (gross used toothbrush and dont buy new toothbrushes). At the end of the day, you made a useful, interesting and (to me) entertaining video. Cheers.
The light of a one match can be seen in from anywhere in a dark stadium" Saying that, bugs are always attracted to the light! Don't let the buggers discourage you man! Thanks man!
Usual enjoyable video Rob, one thing on the cost of tooth brushes, some supermarkets have a 'basic or budget' line which s subsidised to help folks with cost of living, 12 p therefore may not be the real cost.
I also think it would be less prone to being grindy. I bet getting a pebble stuck in the bristles is going to be a lot less wear than normal gears, which might just bind and break.
Boat motors go forward or reverse using the same shaft, splined to two identical gears facing opposite of each other. The power in from above gets locked into only one of the two gears, one will drive the boat forward and the other in reverse, but the engine continues to turn the same direction either way.
Nicely explained (as usual)! It would be a bit of a bugger to print but rather than bristles you could use a spring. Twisted against the spring helix and the spring will try to expand and have a high friction, twist it in the opposite direction and it will just compress the spring until it slips along nicely! I do believe they make ratchet less ratchets this way, with a flat cross section spring.
In regards to the bolt. My father thought me as a kid to point in the direction of where you want the nut or bolt to go and den turn it in the direction of where the rest of the fingers are pointing.
I use the right hand rule for right hand threads. Point the thumb of your right hand in the direction you want the fasteners to go and turn it in the direction that your fingers curve to make it go in that direction. For left hand threads, use the left hand in the same manner.

We get the power while they get to play!....
One thing that was possibly left out is the fact that you need to use the energy that's created in both directions and not just wasted . So you would are just redirecting the energy rather than eliminating one set
I really enjoy your videos especially your infectious enthusiasm lol. My first thoughts on the bristles was i wonder if a used brush would be less efficient? As for wearing out quickly I guess the bristle heads could be spring mounted (like motor brushes)? Ignore the haters sir!
I'm very familiar with your toothbrush pawl, having used "feather boards" on my router table for years, I wonder if you could adapt your gear tinkercad drawings to have a slot/clip in shoe on the meshing faces to hold the toothbrush heads instead of glue, this would facilitate easy and quick changeovers 🤔
Molto bene ; ovviamente anche due cricchetti di bicicletta , montati contrapposti , faranno lo stesso lavoro ; mio suocero , Perotti Giuseppe , nel lontano 1940 circa , ha applicato questo sistema alla sedia a rotelle per invalidi che aveva una leva che sia spingendola che tirandola , otteneva un solo movimento . Very good ; obviously also two bicycle pawls, mounted opposite each other, will do the same job; my father-in-law, Giuseppe Perotti, back in about 1935, applied this system to the wheelchair for the disabled which had a lever which, both by pushing and pulling it, obtained a single movement.
I'm a bit late, but... I wondered if you could use the "bristle clutch" as part of the drive part of the bevel gear, itself, since it doesn't need, as far as I can see, an actual 'ramp' to have it 'see' a pawl....it looks to e (simple folk that I am), that the angle of the bristles makes a 'pawl', all on its own? This might reduce the maximum torque transmission, but drastically reduces component count??
Totally off topic Rob but I was thinking of an experiment at school where if you heat a copper penny then suspend it over acetone it maintains that heat for as long as the vapour lasts. I wondered about that application for a Stirling engine or maybe paltier or even steam boiler. Would the act of taking energy away stop the catalytic reaction?
I don't think a 6 month old toothbrush, wirh softened, splayed and bent bristles would have been effective, hence the use of new brush heads. Would like to see a larger version with nail brushes!
Probably a silly question, but since your always up for the challenge of testing new ideas thought i might ask, i wonder if you could do a test to see if the toothbrush heads could be stacked facing a slight angle around a circular disk and see how effective it is as a turbine, to spin the disk when hit by a wind. Similar to your feather turbine idea.
It's easy clockwise and anticlockwise are right handed and left handed motions, respectively. Point your thumbs along the axis of rotation in the direction of force and you will find your fingers curl in opposite directions, the right hand is clockwise and the left hand is anticlockwise, now if only we had a saying that could dumb down this basic understanding so easily a child could grasp the concept...oh wait.
@@nerofl89 Well sure. But, the problem is that the childhood saying doesn't have an intuitive "Thumby to Top ... Curly whirly til your fingers stop" part... like, Thumby To Top, Lefty Loosey, Righty Tighty, Curly Whirly til your fingers stop. heheh
@@marcfruchtman9473 I see you are just a disingenuous individual, hold a screw driver in either hand, and your hand naturally rotates the appropriate right hand naturally drives the screw inward and left hand naturally extracts. Maybe when you stop being intentionally disingenuous people will actually take what you say seriously.
@@nerofl89 Apparently plenty of people don't understand it, including Robert Murray-Smith @ 1:11. So, no, It is not intuitive, because right and left are not intuitively designed into Clockwise and CounterClockwise. My hand, naturally rotates in both CW and CCW rotations when holding a screw driver. This is why many people don't understand it until you say Clockwise and Counterclockwise. Maybe you are misconstruing my attempt at revising the childhood Left Loosey as disingenuous? I was serious, I don't think children understand it well, and it seems incomplete. But, anyway... I prefer CW and CCW when looking at the top of the bolt... just as the video says.
I'm glad I'm not the only one who finds lefty loosey and rightly tighty completely pointless. Especially when I'm having to join 2 sections of pipework together using a threaded ring. Lefty and rightly mean bugger all to me in those circumstances when the threaded ring looks exactly the same no matter which end you're looking at it from lol (genuine work grievance)
Ah yes, it seems you were failed as a child since you were not taught that clockwise is a right handed turn and anticlockwise is a left handed turn. Easy to learn just point you two thumbs along the axis of rotation facing the direction of force you wish to insert a threaded object towards, unsurprisingly the right hand is clockwise and left hand is anticlockwise and you will find outside of a very select few applications the right handed turn tightens and left handed turn loosens, so easy you could make a children's saying out of it...oh wait.
as always an excellent and entertaining episode. don't worry about the negative comments some people don't understand that you create all this for free.
Yeah, that "Left loosey...." phrase never worked for me either... 😋 . That 'Bristle Drive' might just be classed as a 'Compliant Mechanism', or at least part employs similar ideas. Check the Compliant Mechanism paradigm out, there's a whole world to explore using 3D printing which is perfect for exploring this area... I've printed small examples myself, they're a fascinating idea and makes you think in a completely different way about solving mechanical problems... 😁👍.
Robert. Make a rocket stove and sterling engine out of little other than dirt. Yeah, an engine, from dirt. It's totally doable if you really think about it. If you can make an engine out of dirt. Everyone has sunlight and dirt, Robert. Which would also make a fernel lense made out of water cool. People can get sunlight and water and dirt. Maybe some plastic to shape how the sun hits the water. A rocket stove can definitely be made out of a hill of dirt. The compartments of a sterling engine can be made out of dirt, too. Make us an engine out of dirt, Robert. Let's develop those 3rd world countries FurlDirt is underrated and misused and treated poorly/under valued.

Little to nothing other than dirt, water, air, sunlight/fire.
