I'm a carpenter, and I also recreate wooden tools used throughout history. My largest projects have been a full size medieval trebuchet, and a full sized wheel crane (the original heavy crane, powered by two men in "hamster wheels"), so these are my best tips. Most likely, all of these have already been covered, but here goes. 1) Increase the accuracy and straightness of your joints. Do full layouts of all mortise and tenon joints, use an actual saw to cut the cheeks, and be sure everything is STRAIGHT. Your frame was wobbly not due to the design, but because of sloppy joints and lines not being straight. 2) BALANCE YOUR FLYWHEEL!!! A flywheel is useless if not balanced! In fact, it makes the process more difficult!! 3) Use hardwoods in the supports. Pine is alright in areas without high compression or torque, but in the vertical supports and the flywheel supports, utilize a hardwood like oak. Using oak for the flywheel could also help with the storage of more energy. 4) Use leather instead of rope. Real leather is much more springy, has superior toughness compared to modern rope, and most importantly, it can lay flat on the flywheel. This gives it more surface area, thus giving more force transfer from the crank to the flywheel. This is why belts have been used on motors since their invention. Hope that helps!

There's another upgrade you could do that would help the power of the lathe: change the wooden flywheel for a poured concrete one. It's more work, and you will need to get the form made right, but your lathe will perform better. Also, don't use your flywheel as the pulley. Put another one on the flywheel's axle; less wear on the flywheel, and you can make multiple pulleys for different rotational speeds (1:1, 1:2, .. 1:n), for different types of wood (hard vs soft).

Hey Andy, this is getting _really_ exciting now! One thing you may like to consider, now that you’re transitioning from crafting to engineering, is that the biggest difference between the two is precision. That make a _huge_ difference when it comes to the success of these engineering projects. Examples include the accurate centring, balancing and mounting of things like spindles and flywheels. Getting proper right angles. Taking the time to get those things accurate will pay huge dividends. Look back at your lathes and think how much their operation might be held back by wobbly spindles and flywheels, pulleys that aren’t quite round enough, things like that. As an engineer myself, the biggest tools I have for ensuring accuracy are measuring tools. There’s a great video on YT if you search for “origins of precision”. Once you can mark out and cut accurate lines and holes, and measure them to gauge their precision, you can master that precision in your constructions.

Piece of advice: ancient doesn't mean poorly made. You seem to be starting from first principles in every case, and that's neither practical nor historical. A big improvement would be to use a treadle spring lathe to make the pulleys and axles for your Da Vinci lathe. Also, instead of cord for your pulley, you'd be better off with leather straps. This would give you far more grippy surface area on the pulley wheels and greatly improve both stability and power. Also, there's no reason not to use a metal bar to connect the treadle to the flywheel. It was just painful to watch unnecessary repeated breakages. Da Vinci would have fixed that first time it broke... so should you.

Having support on both sides of the pulley's axle is a HUGE thing, as is having a properly balanced flywheel. You should be able to balance it after construction with lead weights- you can get lead patches for balancing fans, or you could drill holes and pour lead into them around the edges. Having a properly balanced flywheel will help immensely. And you don't actually need external power for metal lathing- there were popular treadle powered metal lathes in the 1800's.

a couple of improvements i can suggest for the Lathe, first of is instead of drilling oversize holes for the shafts, you cut a bearing block out of a hard, oily wood with lubricating holes for oil. this should help with the wobble of the shafts a bit. another fix would be to turn (by that i mean the woodcutting term) the flywheel in place so that it is balanced and you should be able to turn a crown on it to provide a place for a flatbelt to ride on. The treadle would ideally be directly driving the flywheel but that may mean it will need to be operated by an apprentice off to one side of the lathe.

I'm glad to see you revisit the lathe! Your last attempt was very rudimentary but this one looks like you might be able to actually make something substantial on it. I suspect that at this point in addition to more RPM, the quality of your lathe work will also be improved by an increase in rigidity. Having your work spin at a million RPM would only be useful if you don't also have to chase it around the shop as you work 😂

Quick question. Why not use a gear system to multiple the number of rotations? Using a large gear to rotate smaller gears that are connected to the lathe would result in the smaller gear performing multiple rotations for each rotation of the previous larger gear. It's the same principle as the pully, however I think it'd give you a more stable rotation. By replacing the rope with a specialized chain you could even combine the two like in a bikes gear system to allow for an adjustable difference in speed and power. Love what you're doing, keep it up.

It’s awesome to watch your skill as a carpenter slowly improve. You seem much more comfortable with a chisel now.

Wet the rope (pully), then pull it as tight as possible. When it dries it will be much tighter. Also use a better knot, and cut off excess. You might also want to to wrap the rope around each wheel twice, AND/OR put a metal band around the wheel leaving a gap for the rope to thread through. Either should increase your run time and decrease failure. the metal band is likely to keep it together till the rope breaks (could be years)... You may need to drift some holes in the metal in order to have entry points to coax the rope through unless you have a solution for something to pull a rope through. Both methods are pretty common in the old days (the metal bands were used on wheels so it would have been a common thing, the only difference here is there is a channel in the middle of the wheel for the rope).

I have a lathe that my grandfather converted to use a treadle from an old sewing machine. It works surprisingly well even with metal. The speed is determined by how fast you pump the treadle. It is probably at least 70 years old and it still functions perfectly. I have some other machinery such as a drill press and a bench grinder that also run off of the same treadle. Grampa was pretty ingenious when it came to such things.

As several people have said there are a number of adjustments that could be made to make it better and still historically accurate, but for what it is and made using the tools you have in the time frame you work in, really cool :)

Nice work. I subscribed because of this video. Looking forward to more. One thing to consider is the vibration from the fly wheel not being centered.

First, this is amazing. Second, I've seen some really sweet treadle lathes that use a leather drive belt, since those are flat, decently grippy, not terribly expensive, and pretty hard-wearing.

so cool to see how your blacksmith skill improved also.

Super cool!!!! Can’t wait to see what’s up the sleeve

Love the video as always! Maybe try leather a leather belt for the pulleys instead of string.

You could use an old sewing machine treadle. They're solid cast iron and the treadle is center pivoted, so you can apply force on the up and the down stroke if you use both feet. Also features a big cast iron flywheel and if you use the sewing machine it already comes with a 4 to 1 mechanical advantage. The machines are solid cast iron as well and could be modified pretty easily - just saw off the sewing end and attach whatever you want to the wheel.

Loved this!!

Super informative, thanks a lot !!!!!

Sweet, I remember looking over the original sketch to figure out how it worked and maybe make one for a smaller space. I didn’t know what the flywheel was originally for and assumed it was more or less the starting lever to give the treadle initial movement.

Nice video man! Also I cool build I saw is from the channel Mr. Chickadee of a lathe with pulley system just like you did. Maybe it helps

Awesome! The lathe is probably my most favorite tool!

You could add iron or steel bushings into the contact points of the wood to reduce friction further, as well as use it as a rim on the outside of the flywheel to add more mass to it.

Nice work, thank you for sharing the entire process with us. If I may suggest, put more attention into your axles, making them more stable should make a lot of difference. And I think that making things more modular should help too, (i.e.- separate the gears from the pulley, the pulley from the "motor", etc...). This way once you've reached a satisfactory level in one part of the project, you can leave it alone, and only change other parts that still need improvements. Good luck

I appreciate you using commercial luber finally. You've proven you can get planks out of tree branches and that's great. No need to keep on doing it over and over again when you know you're never even trying to set out to become a master carpenter. You've got enough of a challenge on your plate even with the crutch of store bought lumber.

This is such a cool channel. Even with my experience using a very small lathe if the work stops or slows down you end up with an ellipse instead of a circle and then it gets worse cause it's lopsided etc... This was the main challenge of any non motorized lathe and takes a lot of skill to coordinate everything in order to finish a piece, if you go out of round sometimes you can't finish the piece. The flywheel would really help with that.

This was nice. One thing I noticed is that you made the pulley concave, but I do remember a video from Steve Mould that would suggest a flat leather strap and convex pulley might work better.

The mass of the wheel also helps keep it turning by writing against the friction of the tool in the work piece. A sandstone sharpening wheel would be a better choice of available.

Your main crankshaft could benefit from a flywheel mounted on one end. Neat video, keep it going!

Nice lath. Try using your current lath to build your next one. You might also try a leather belt. Fit wet leather, which is stretchy then letting it dry to give you a tighter drive belt. You could also add a wedge tension adjustment to increase the friction on your rope belt. Use the pole lath to get rounder and smoother wheels, and pulleys. Wet your pegged joints to chaise them to swell and hold better. Love your channel. I have been following you for years. Thank you.

I've often thought of making a treadle lathe using a cheap mountain bike rear wheel as a flywheel. The freewheel system is built in, and you can vary the gearing as desired. Wrap the rim in iron tie wire for extra inertia. I think that'd work pretty well.

Respect for your work

Great work! Looks like so much fun (and hard work) to build all of that. The results are super impressive, especially given your tool limitations. I wonder if a gear would be more stable than a belt for amplifying the speed of rotation; the flywheel is by nature going to have a lot of wobble to it, making the belt method hard to keep running; but maybe some small gears can reduce all that torque into rotational velocity in a more stable way.

@jeffspaulding9834

Жыл бұрын

The flywheel doesn't have to be wobbly. If he trued it by turning it on its axis (turn as lathe work), then balanced it by either drilling holes in the heavy side or adding weights to the light side, it would spin without causing the lathe to move. The bigger problem is the play in the axle. Bronze bushings would help, but you really need a way to turn metal first, which is a chicken-and-egg problem. Using a flat leather belt instead of a rope and stiffening up the structure would go a long way to help.

It might also help if the flywheel's connection to the axle were widened or buttressed and the axle lengthened to help reduce lateral wobble. I would also consider a hollow flywheel with spokes to reduce the weight to angular momentum ratio; that would make it a lot easier to work with and would reduce the strain on the axle.

Since the main flywheel is working pretty well, I'd try to do the gearing off of that. Do one speed up going away from the axis, then another going back toward it.

when making pulleys, using leather strips with what is effectively iron staples at the ends will yield a smoother and more efficient system

Man, this channel is really underrated

I love this series

Please finish this project!! I AM SUPER INTERESTED IN THIS I MIGHT TRY THIS MYSELF!
