Hi Andy, love the video. I am a bearing engineer and appreciate the attempt at a rudimentary thrust cylindrical roller bearing. In order to prevent your wobbling issue, you need to add more rollers to increase the load sharing and fix the rollers along their pins so they stay in the same rolling path and do not slide axially (this will prevent slippage and reduce friction). In order to accommodate an increased number of rollers, you may need to forge a more advanced cage design that maintains roller spacing. You may also consider a larger roller diameter to increase load capacity. Also be sure to grease adequately. Love the content!
Precision has a very specific meaning in manufacturing and engineering. Modern precision didn’t exist until the beginning of the Industrial Revolution. The way that you can achieve precision begins with three blocks of granite or cast iron. You rub two of these blocks (we’ll call them blocks 1 and 2) together until they perfectly fit together. We then switch out block 1 for the third block (block 3) and repeat. Then we switch out block 2 for block 1 and repeat. We keep repeating this whole process another two or three times. At the end of this all three block should have a perfectly flat surface, and I mean *PERFECTLY* flat. That surface is the beginning of precision. From there onwards it’s all a material of geometry. So that’s how you create precision with rocks and math.
@@GusCraft460 That's really cool, but weren't there prior methods too? Like the ancient Greeks and Egyptians creating perfect circles, triangles, and squares from one another, from which they then created perfectly flat surfaces. I remember reading about how the creation of geometry unlocked the world of precision all the way back then, and saw videos with examples of foundation stones with perfectly flat faces as evidence. Edit: Oh yeah, I almost forgot. There's also the antikythera mechanism. That required mechanical precision, and was ancient in origin.
@ there’s precision, and then there’s *precision*. While many ancient cultures could do the geometry part easily, without a perfectly flat object to use as a reference you can’t get modern precision. Ancient cultures could get as precise as about 0.1 mm, but modern precision can go to as little as 0.001 mm. The difference like the difference between making wood screws you trust to hold two boards together and the screws that NASA uses to hold their rockets together.
And now you see why very rarely see small windmills. The power of the wind becomes useful only with larger sails, hence the use of water and water mills; the inertia and momentum of water carries so much more energy that it makes it so much more efficient, especially material wise... But as you stated, its not given to all to have a running stream close by, contrary to windpower. All in all, was a great episode! Neat to see you all learn from the past iterations of the wood gears and the progression of knowledge and usage of metal working with the rollers ! Very cool to see :) Looking forward to the next episode!
One thing that might help would be if Andy made some ropes and pins to tether the windmill down with. the problem is that the wind is allowed to pull the machine over without anything resembling a foundation holding it in place.
In Guédelon in France they build an medival water mill an had also problems with binding at the beginning. After a while it runned smother and had the same wear marks than found of medival mills. So those wooden gears just need time to work them self in.
I work as a maintenance guy for a factory. We call it "wear time". Imperfections in parts or imperfect pairings (due to new parts being put in an old machine) tend to wear each other into smoother interactions over time. The knee jerk reaction most people have when they repair or build a machine is that it "doesn't work, try again". But really, they should just run to the shit out of the machine until it either breaks or works better than ever.
I have a photo of a middle eastern design where the central axis sticks out several feet. Guy wires go from the end of the axis to the tips of the sail supports and to the vertex of a triangular shaped sail. Note, only a single, light weight piece of wood supports the sail much like the mast on a ship. The angle of the sail can be adjusted by the length of the guy wire (again, much like a ships sail).
Wind tends to blow only from two directions in any location and one of those directions is directly opposite the first. So long as you have an accurate record of that (called a Wind Rose or a Wind Compass) the whole need for a swiveling windmill doesnt seem needed. It would let you capture energy from 90% of winds at a location without needing a swivel. Then again Davinci isnt exactly known for coming up with the simplest solution for any given problem (lookin at you "just add a connon for each direction you might want to shoot")
I am well impressed at the craftsmanship on the gears. There have been a couple projects that have gone by that I was thinking "well it won't work if you don't take time to refine it". But this, very well done sir and team.
Wind MILL, rhymes with Hill, not wind MEAL. I enjoyed the video but that pronunciation was more painful than a midwesterner trying to say "Aaron earned an iron urn"
@Ashersrequiem making fun of pronunciation is one of the lowest, disrespectful, and least thought out forms of insult. Not only are you an asshole, but you're also bad at being an asshole
After you test more smaller blades, you could also test wooden airfoil propeller blades, to see if using the heavier wood with an airfoil shape would be better than using angled cloth with a wooden frame.
I could be wrong, but I believe the steam turbine is the most efficient type of steam engine. It also shouldn’t be too hard to make a rudimentary steam engine: make an airtight funnel, add a shaft with metal fan blades increasing in length, and push your steam through the narrow end. Something to think about when you revisit the steam engine.
If I remember correctly, you want smaller wings to slice through the wind and not just catch the wind. That seems to be the reason why modern wind turbines have thin wings.
I think with a small windmill like this a VAWT configuration would make more sense, as with a HAWT configuration like yours at a small scale, more force goedms to tipping the windmill over than turning the turbine.
Love all these videos. Please watch some Paul Sellers videos for some woodwork tips. Also would love to see an underestimated technology of ball/roller bearings, I feel like you are getting toward this step now to move more away from wood. They really make the world turn. Again, been watching for a long time keep it up!
You need to study SAILBOAT Sails. They do not work intuitively. You get the MOST lift when the wind comes from the sides. This will also affect the position of the tail vane.
Honestly i think the fact that you seem to still be operating in a suburban neighborhood is probably whats holding you back. If you owned a larger field with a larger workshop you could build these large projects to scale without concern. The base for this windmill is way too short and no where near wide enough to even be considered useful. I mean windmills need access to stable wind. Low height with fences and trees interferes with that.
WOW!!! WHAT A WRECK!!! I'm pretty sure DaVinci would be ashamed. You didn't balance the blades, you didn't do anything to reduce the blockiness of the vanes, and by offsetting all of the vanes to different distances from the axis, you put unnatural strain on the joints which caused excessive drag. I did not even hear if you put any kinds of lubricant in there, but if you didn't that would also contribute to it not working. Since they had all kinds of oils and animal fats, you should have made sure the moving parts were all thoroughly lubricated, and the holes [for the axles] should have been sanded very smoothly. Also your pivot plane should have all been floated on grease, AFTER a good fine sanding.
Does rawhide made a good bearing material? those dog toys made of it feel almost like plastic. pliable like putty when soaked, much less bindy feeling than wood when dry and lubricates when damp.
why is it made out of wood on rotating contact surfaces? Davinci knew about these problems and they would be made out of brass or iron (or at least wood with metal "rings").
The center of the blades are spinning much faster than the edges of the plates they need to be slightly more curved to catch more wind the smaller you make them the faster the spin because they'll be less material and less weight and again the center part where they mount they spin faster than the inches❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤
All of your material was way to heavy, maybe cost effective, but detrimental to the project, less wood, but a stronger species, would more than likely solve most of your issues, and you can use lard for grease too,
The base needs the legs farther apart than the top. Less likely to fall over that way, (That's right! I'm a Douchebag Armchair Engineer! Just sayin'.).

If you make the base slightly conical instead of flat, it should work better.... Aka, create a medival thrust bearing!

Use non absorbent lubricant, it will make everything easier.
