That shot where you were able to turn the wheel pretty much with your fingertips with Andrew standing on the front really showed off how light the steering must be. Should be magic on the road, given your work with geometry I bet the weight buildup under load should be great too, as well as the feedback.
We expected it to be good but not this good given that the steering on an Mx5 is just ok. With new bearings and the wheel on tight it'll be another level
Since the car is set up to be so responsive, how easy do you anticipate the steering will be on a long road trip? Did you say that you have built in a lot if caster? Also, please can you take a plan view photo of the car (to show off the wheel planform, thanks.
Yes 8° of caster and itll be pretty aerodynamically stable so It'll track well even with the fast steering, with small inputs it should be fine on the motorway Plan view as in from above? I'll see what I can do 👍🏼
Towards the beginning of this video, you were discussing the plastic "cap" that covers the steering wheel hub. IMHO, polished would be distracting, something shiny that could reflect back into your eyes. How about something marine inspired with wood and more slim fitting?
Its go a super short wheelbase and open diff so it'll be less Tokyo Drift and more 60s F1 big 4 wheel drifts but that steering angle will come in handy
have a dyane, I am 1.80 if the seat is higher than 11 cm from the floor the horisont disapears over the roof if I explain it right. Now I got it right at about 10 cm as it was a little annoying only to see three meters in front of the car, and that was if you were not driving up a hill, I sugest you do the same. don’t you think that matters ?
It *was* getting exciting. Now it's getting painful seeing it looking so much like a car but there's still so much to be done before we can see it hit the road. Some day this car is going to be in a museum and many people will be appreciating the craftmanship in person. Meanwhile, it will be a treasured family heirloom.
When I have started my Locost build, I have purchased a mini lathe(cheap Ebay $1000 - I don't recommend them(I had to re-machine all the ways and tailstock spindle hole), and a mini mill for around $500). They helped a lot. You guys shouldn't have the pedals in there as well, when you are mocking up the steering?
To cover the backside of the boss...one could use something like the cover that hides the electrical box above a lamp...finding the proper diameter should not be too difficult, and they are relatively inexpensive.
for the back of the steering wheel, you could use the end of a leather shift boot with the narrow end inverted inwards around the steering shaft (to make it look nicer) or a universal CV boot to cover it up in a more compact way than that plastic ring. Im sure you could easily engineer a way to keep it secure to the back of the wheel. edit:further along in the video...i guess you just polished it haha.. that works.
I'm building an NG TF based on an mx5 and I made the exact same steering for my car using an additional column piece from another mx5 ad used two universal joints just as you did. Glad to see what I was doing was OK. Malcolm in England
I was waiting for this video where your team provides an up-to-date progress video format. This is the perfect video to send to people when they ask me about one of the best car-building channels where you can learn and see excellent work, along with explanations of each decision. Great work!
This might be a stretch for what you would want to do, but you could design the steering wheel hub in CAD(computer, not cardboard) for it to be sent to a place that does metal 3D printing. In that way, you could make it whatever style you want and as bulky or not as you want while making it much more premium than the plastic one you have.
Enjoyed that, thanks. Just checking your maths on the weight saving of turning down the intermediate shaft. More like nearly halved the weight as the cross sectional area of the outer part is much bigger than the inner part - Pi x radius squared. 19mm shaft cross sectional area is 283.5mm2, 14mm shaft cross sectional area 153.9mm2. The other thing crossing my mind while watching Oliver polish the boss - might it reflect in the windscreen? If so would annoy the hell out of me and I'd be reaching for the matt black paint!
@@daveparry1569 Thanks for that when I'm on camera I always air on the side of conservative when doing approximate maths off the top of my head haha. It should be fine because it's pretty far back and the windscreen has a gradient but we'll see
Alot of drag n drive cars have a steering column the swings to the center of the car. I’m sure engineer dad can come up with something robust for a rally car
Yup Raid uses same PCD as Nardi. its not that hard to find anything for but yeah Momo PCD is far more common. D1 spec has a snapoff with both pcd's that is not that expensive but still pretty good.
I used to manage a Vespa shop in Gainesville, Florida and would laugh at the English translation for the Chinese scooters that we carried. Also, remember the old hot rod adage, shiny equals horse power. Love the channel and the interaction between you and your dad. When you get on a tangent about Rally or something, I’m in heaven. Reminds me of my dad. Thanks.
@@OliverPickard fair enough I have seen a video demonstrating it but I was originally told about it by an old engineer when i was younger and the information stuck, Anyway it is what it is. On another note the hole in the bottom of the steering boss would be a convenient place to hang a small bit of pig tail wire for the horn. Not wrapped around the colum like a rally car just enough to work and a bit of a nod to racing design
