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?

I like the use of wood, where possible - greenest of materials. You are a great engineer. And video maker!

Exelent job 😊

nice and amazing job, how i can do a tool for internal gear M1 Z60 many thanks in a dvance

Very nice work. Perhaps it might power a small R/C boat?

Hello How much must be of centre?

You don't need a tilt lock. Just use 2 gas struts.

Nice kit piece, it looks sturdier than my home made design. Enjoyed this video, cheers!

Nice tool. Very nice work sir

hello, is there a book or handbook so we can study this geometry design fundamentals

This approach is good for model engine cams where dynamics safety margin is (hopefully) high and noise does not really matter. For other cams, God invented the Landis CNC cam grinder.

Very very interesting video and many thanks. Jim from Australia.

There seems to be an error in your spindle attachment design. The two spindle pivot points are parallel to the wheel, this gives your tires scrub while turning. The spindle pivot points should be designed, so that if you draw a line through those two pivot points, that line should bisect the center of the tires contact patch.

Muito bom!

speaks more than a radio

Very good job, but why don't you put on your safety gloves?

very useful video ! thank you

Eureka!!!!

I want to buy it. Can you sell it?

I guess if you don't have the correct change gear for the dividing head you have to use the latter to make a change gear, but then you can also use the custom gear in the lathe for threading.

i always thought about crank out frt.

Gracias por tu video

Joli travail bravo et merci pour le partage

im still gonna fill out a hurt feelings report because u left us. At least tell us something

Very clever creation. Thanks for showing this!

Good .. To find centrale axe use lathe
