Happy new year! wow!!! amazing job!!! thank you ! the diagram on CAD is great help! can you build a simple prototype with 3D printed parts first? Remote controlled with E motor so we can see a small working prototype.

This is just wonderful. So happy to see a new "improved/rethought" recumbent. Excellent, just excellent.😁

very cool looking forward to the build

I like the ability to fold the wheels in for storage (although that will be less useful if you put a body on it) but concerned that the locking mechanism has weight and stress on it all the time and could fail while riding. How about having its “failure mode” of the lock cause it to unfold into riding position and the lock mechanism is only there to hold the wheels folded in a drooped position? That way you could fold both wheels just by lifting from the centre shock area and pressing the lock with your thumb or finger. I realise the wheels also need to be stopped from folding when airborne over a sleeping policeman or for maintenance etc but that wouldn’t need much strength to stop it happening.

I like the new design as its quite an evolution, what will likly be a typical tilt when doing a sharp corner? (Will it provide a more leaning experience)

Bonjour et bonne année depuis la France. Nice engineering. What is the main goal of this project ? Is it to create a design 'only', or to create a business and manufacture it ? Do you expect to earn money from making such machines in the future ?

Happy new year, looks an interesting evolution of your design, and I'm looking forward to seeing the build

Absolutely brilliant! As far as the differential issue is concerned, I have wondered if a solid shaft between 2 freehub wheels could serve the same purpose. This would allow the outer wheel to freely accelerate on corners while applying pedal force to the inner. As a bonus, it would function like a dif lock on slippery surfaces. There would, however, still be a lot of drivetrain design issues with the tilting

Can't argue with that

Thank you

Mis respetos es Ud una persona muy inteligente con muchos conocimientos, gracias por compartir saludos desde México

I really think you could rescale to suit the range of 1/14 rc trucks , so many people would buy a mass produced gearbox for model trucks man , so cool engineering.

A screw to apply grease, I love it.

Amazing episode.

Great teacher.

Thank you for this amazing episode,

It’s very nice. I’d never used it on my little hobby lathe because I don’t do production. Years ago I had a Logan lathe, and I had an actual turret that would replace a tail stock, but it just sat on the floor.

Good morning I have wondering I want to make the gear, for example if the sample gear 20teeth and 30 diameter so the new gear have to the teeth and Diameter? Thanks I’m looking forward please 🙏

2 bicycle coil springs on the 22 mm cf push tubes along with your arm strength might make it better to get back vertical. Its easy to tilt L. or R..

That's awesome. I have another guitar part project needed if interested. A gear for 175yo tuning machine heads that has worn down.

Ive never seen a fly cutter mounted on a face plate before, very neat idea

~Very nice milling work!

Very nice!

Hi..Would you be willing to make me this gearbox in a 'kit' form as i would love to buy it? Thanks !

Thank you for the excellent video, my only question is would oil be better for quenching the hardened steel parts?

I saw your article in Model Engineer's Workshop magazine this month. Well done!

What about using longer (or shorter) lower (or upper) control arms to purposefully induce camber gain to help minimize tire scrub in a lean? As I think of it, I can imagine this may compound the problem, making it worse. 🤔 I really dont know - Just a thought(less) question from a poorly self educated dreamer.

A very enjoyable watch. The series covers it all. Research design and manufacture resulting in a strong prototype to build from. Respesct for your great dedication and achievement.

This Gearbox is wonderfully designed and made and i would certainly buy this if you could make it available as a DIY kit...What are the chances??

An excellent video. Thank you for sharing your knowledge

I enjoyed watching this process. Thanks for sharing!

Very nice. I was wondering how you were going to align the holder bores to the center line, now I know. Good old fashioned machining, no CNC here but still get mass production.

Many thanks, very useful content. Just started seeing how I might be able to do some indexing in my hoppy workshop. Best regards Jim from Worcester.

Ok. But I would definitely not rely on the bored hole in the turret and a grub screw to hold the adaptor. I would face the each turret hole and thread. Bore to suit a threaded Chuck with locater spigot. Otherwise this looks ok.

SIMPLE AND EASY.. THANKS

nice tilting and steering mechanism!!

Brilliant. Thanks for letting us witness your amazing skills.

Brilliant! Thank you!

Can a case-hardened workpiece be unhardened? I would think that you could soften it by annealing as if it were carbon steel.

Wow ! Great work

Wauuu 👍👍👍👍

Tolle Idee ich mache es auch so.

what a beautiful old contraption from a time forgotten . thank you for taking the time to share your traffic skills I will have no problem paying the money for a set of gear cutters after seeing this

So the involutes are close enough to a circle? Or is that an approximation?

I am so glad that I blundered into this channel. Have planned to build a Eureka tool for some time and enjoyed watching your implementation. Law’s book does show you everything you need to know to build one of these but there is a lot to be gained by watching someone else do it first. Also interested to see your various shop-made indexing and positioning tooling. Thanks for posting. Subscribed.

That’s a useful project to see demonstrated. I remember the seatpost split clamp that came with my HED R1C carbon frameset (bought 15 years ago) being utterly useless and having to source something else to clamp the seatpost. I wasn’t into machining then so couldn’t make one. The HED made for a very good budget TT frame all the same. More recently, I did make a split (on one side only) clamp to go on my lathe’s tailstock quill for mounting a homemade DRO. It works quite well. However, I cocked up at the first attempt and had to make the thing again; I didn’t drill the hole centrally through the ring thickness. I also discovered I needed a rather long tap to go through both sides of the clamp. On reflection, maybe I could have drilled with the tap drill all the way through, then tapped only the lower half from the outside, then drilled the upper hole larger to give free passage to the cap screw. The voiceover is fine. I would be happy to see it contain even more detail.

I’ve seen a great many KZbin videos on knurling, and several showing attempts at making the Hemingway kit that is the basis of your tool. Sadly, though, when it comes to doing some actual knurling, very few people seem to be able to produce what could be described as a good knurl. It’s very refreshing to see that you’re clearly an exception to this, as the knurls you’ve produced look excellent. I bought the Hemingway kit last year, but I’ve simply not had the chance to make significant progress with it yet. Would you be good enough to answer a few questions? I see you held the axles the knurling wheels turn on in place with hex nuts. I think the kit suggests tapping the relevant side of the slot and screwing the threaded axle end into the tapped hole. Did you use the nuts to provide a more secure fastening? Did you use the 3/16” wide knurls Hemingway suggests? Do you find the Tommy bar gives enough torque to easily tighten the wheels down on to a part? I know this rather short tommy bar is what Hemingway suggests. Are there any other departures you made from the Hemingway instructions? I don’t remember the H shim being in the instructions, though I’ve not got these in front of me at present to check. Anyway, all the best with your channel, and well done for the exemplary demonstration!

It was great fun watching that! Brilliant stuff.

Can you try to lean the body while keeping the camber of the wheels steady?
