- In this episode we are fitting a Raid steering wheel to the Pickard Mosquito GTM (as used by the Lamborghini Miura SVJ and Lamborghini Countach as well as Many Porsche racing cars). connecting our cam gears steering rack (the company who made racks for Ferrari) but that will take the Making of a custom steering wheel hub and some serious engineering.

This Video Is Number One Please Enjoy Your Car Life Universal Type
Gotta love Japanglish
@@gafrers I hope I'm that entertaining when I speak Spanish and French
Half of this channel is turning bits of steel into swiss cheese. great work guys as always
So that's what a "plum line" means! 😋👍
Hi Andrew, As a retired engineer myself (F.E. College) I really enjoyed watching you teach your son an enormous amount of "old school' techniques which nowadays are lost from mainstream engineering schools (unless they're lucky enough to have there own 'Andrew'!)
Seeing you file the flat on the tough piece of material, I thought, you haven't a mill to do it, but you do have a lathe! If you put a fly cutting tool in the lathe chuck and the shaft in the tool post you can feed the steel bar toward the fly cutter and then lock the carriage and use the cross feed to take a cut along the the surface of the bar, then repeat till you have the depth and length of cut required.
Hope this helps you for the future, Denis
cheers,
Denis
I would recommend a Snap off quick release , they come with the nardi pattern as well as the more common one . also if you tidy the boss up and paint black it should look a lot better
Always Great work, explanations, humor. Full package
As I've said before I love the fabrication episodes. This channel improves so much week to week. Thanks to you all for your efforts.
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
Man that white and steel-it together looks smexy! Loving the weekly updates.
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.
@@thomperkins thank you so much
Steering oliver as you say in the introduction it’s looking like a car now a fantastic car at that
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.
Steering looks awesome. Your dad really is a genius. You are no slouch either. I really enjoy this whole series. Car will be amazing when finished. I cant wait to see it. Thanks for sharing.
Thank you so much
Great video again, your dad's filing is awsome, part man, part milling machine😉 Re the hole in the boss (nice work btw) it needs a flush fitting plug either ally or black plastic.
There's an interesting thought
Your dad filling for hours takes me back to my apprenticeship days lol
Me too, but I never got the knack of it. 😊
Thanks guys, excellent work.
so glad its coming on........Stunning build
I think the word you were reaching for at the end is serendipity! Very cool. The boss could be crackle black?
@@Ralph2 Something like that yeah or destiny.. my brain had stopped working haha. I do like crackle black it's underrated
From what I remember on my gtm a lot of the interior steering components were triumph dolimate I think
Ahhh that makes sense thank you
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.
I'd be sad if it ever goes in a museum, it's built to be driven
Second donor on the GTM is a Dolomite Sprint - steering column, binnacle, instruments, radiator etc.
Thanks 👍🏼
@@OliverPickard The Dolly also has a short intermediate shaft in the steering with U/J's. It is also a Jaguar part with a different number which make it more expensive. At least it was when I bought one for my Dolly way back when. Stag one is similar. I was wondering if you were going to need/use a pillow block bearing for extra support.
@@delukxy We regreased the original bearings but I don't think they're up to much
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.
@@silaskoning3050 very true but with everyone doing cad and 3d printing I want to keep this car as hand crafted as possible so no cad
Thank you for the video
You are very welcome
Getting close to "Movement by Self Power" LOL
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.
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
Leather gromit for the steering wheel all day
You should put quick reliese Hub for that steering wheel, solves all problems with going in and out of the car 😁
It also adds 500g and costs money that can be spent on other things so unless we really need one I don't want one. once we've got the pedal box in we'll know for sure
I'll probably need to comment again after I watch 😂. But please keep it coming.
😂😂😂 I don’t do yoga so I’m with you pops
Thanks!
@@matthewweinle8639 Thank you so much
Turn a steering boss cover out of oak to match your gear knob
@@simoncrawford2240 we can't have anything that splinters because of regulations
A camel is a horse designed by a committee. In the South African mining industry I've heard engineers say an elephant is a horse built in a mine workshop. I'm sure you have calculated the required strength of your brackets , but after 7 years in a drawing office doing conveyor design your brackets concern me . When I build stuff 3mm plate is my bracket go to . Did you consider making your lower shaft collapsible ? Anyway cars looking awesome keep the videos coming !
@@paulwhite7475 The brackets are 2mm and overkill strength wise but being steering it's nice peace of mind.
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
@@jdolecki100 like an old Thunderbird? 🤣
Regarding your steering wheel; on my old BMW 2002 I could keep my knees apart while driving, except when I went to 'heel & toe', and then my right thigh would be against the bottom of the wheel. I got one with a flat bottom to give me just enough room, and found that the heel & toe opportunities were usually during corner entry while the wheels were relatively straight. If you feel crowded when first driving you may find a flat-bottom steering wheel a good option.
Watching the end discussion from the front of the car, I am wondering if you are going to triangulate the front suspension/frame nodes to the base of the a-posts/cowl to increase torsional rigidity? It looks like a tube box frame is all that extends from the firewall to the coil over mounts.
You guys know what you’re doing, so maybe those tubes are enough. Just curious. Love what you’re doing! Thanks for the edutainment.
There's tubular triangulation to the A pillar built into the firewall and the distance from there to the suspension mount is just 12.5cm. it's absurdly stiff as are the coil over mounts themselves, even though it's not designed to have unending grip it's got more than enough torsional rigidity for massive slicks should we ever wish
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.
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?
We can't have wood anywhere near the steering wheel because of the legal regulations
Paint the boss black, you cant see a black hole on a black boss....
that's it, I'm subbing for more of this nugget. btw, I really feel that you need a quick release hub for the wheel for accessibility
Its shockingly easy to get in and out compared to most sports cars
@@OliverPickard I wouldn't know much about that, I'm only 5'8" 😅😅
You could take it drifting with that degree on the steering wheel
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
rubber coupling/joint is from Austin Metro ( not mini ), so steering shaft is from metro too, probably, or triumph dolomite
Its not metro but might well be Dolly thank you
@@OliverPickard Many years ago I made a column for my Mini Marcos using one of those rubber/fibre u/j's and used the bottom part of an Austin Allegro shaft. It had the same splines as a mini and was the same diameter so fitted in the mini vylon bushes.
Another brilliant video as always, loving the new schedule gives me something to look forward to each weekend.
Got into your videos originally for the Jolene content and i am finally deciding to take on my 2cv which has been sitting for years.
What do you use for sealing the underside of the car? I was leaning towards an industrial PU floor paint.
Cheers!
@@keatk_ on the Mosquito we used Steelit which is a single part polyurethane based paint check out episode 80 for more
@@OliverPickard yes but seems tricky to apply, I really like the look of the paint you used on the Dyane, been sifting through the old videos but couldn't catch what exact paint it was. Any help would be awesome!
@@keatk_ I have no idea what that was dad got it in a massive tin on sale but it was like smooth hammerite
@@OliverPickard gotcha, I'll keep hunting, thanks!
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?
It would but we haven't made the pedals yet but we know their dimensions
Just a thought, thinking a cv joint boot on the boss?
At this point it’s also worth considering where the speedo and rev counter will sit behind the wheel. I rebuilt my GTM to original spec and can’t see the top half of the rev counter 🤦♂️
That's another benefit of the bigger wheel but don't feel too bad the wheel on a 911 completely obscured the fuel gauge for decades haha
not sure how the upper steering shaft mount will work. are you welding it? how will the shaft tube come out of the car if needed?
@@AlfaElaborazioni yes that's where the aluminium cam comes in
Remember that the lathe chuck wrench should never be in the chuck unless it is also in your hand.
unless you wanna see it fly across the room, best case scenario
Can't you weld the two hubs together?
@@nicusvisser5229 They are two completely different types of very old cast aluminium which is pretty much the worst thing to weld in the world and could end up just destroying it
I thought that the universal joints had to be 90 degrees out to rotate smoothly.
@@juscozcustoms I don't know where this myth comes from but you aren't the first person to say it today
@@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
@@juscozcustoms I'd rather like the horn on the stalk to save the weight of a clock spring, button and wiring
@@OliverPickard whatever toots ya horn 😆
could always weld up the slot. Id leave the plastic off and polish it.
Welding cast aluminium like this is extremely risky and chances are it could destroy the part
@@OliverPickard Maybe epoxy a piece of aluminum with a shelf cut into the ends so it would sit flat?
Oliver, now paint it black.😂
Nooooooooooo!
Anodise the offending item. A piece could be crafted for the indicator hole and be invisible if done well.
May I ask, what’s the O.D. of the shaft spline and PCD of the steering wheel?
Its about 36cm which is about the same as what you'll find on a lot of Mx5/Miata and nardi bolt pattern
wooden cover/tube? I mean for steering hub
@@ocho7011 we can't have anything that splinters that's why we couldn't fit a wooden wheel
I may be wrong but shouldn't the two uni joints be out of phase as they would be on a rwd driveshaft? (I don't think these are?) Or does it not make much difference in a steering shaft?
It's not spinning like a prop/drive shaft so things like resonant frequencies don't matter but dad's made literally thousands of prop shafts so I'm not questioning his wisdom on this stuff
Looking at a driveshaft video I think it's correct for what I was thinking anyway, btw I didn't mean angles of the uni joints but rather how the 2 joints line up on the intermediate shaft. I was unsure of the terminology. 🥵
@arrindaley3714 It's all good 👍🏼
All the cross cart, off road buggy, builders line them up the same as Andrew. I think it makes the steering smoother. One of them explained it but I can't remember which one or which project. I'm thinking either KJ Racing or Rather be welding.
@@kizzmiaz yeah I knew a single uni joint produces an uneven speed, (looks like a sine curve), a second uni joint can even it out if aligned correctly, it took looking at factory driveshafts to confirm the alignment.
What fancy geometry things??
We've made many videos going into detail on this if you want to check them out there's a full playlist linked at the end of the video
@@OliverPickard Well that was a pretty straight forward question nicely fobbed off. So I have trawled through some of what you referred me to and it is incredibly underwhelming. You bang on about engineering and design continuously but there is little evidence of either in the videos. The wooly explanations are very frustrating
Would black anodised finish suit the wheel hub?
It may it depends if I get reflections on the windscreen
From which car is this steering rack?
its a RHD quick rack made for a Mini by Cam Gears LTD who made racks for the likes of Ferrari that we flipped upside down
@@OliverPickard ohh okay, thanks im looking for something quick and simple for my smart roadster
@@ocho7011 the herald/spitfire rack is also a classic choice with a bunch of ratios to choose from. Its what they used in the europa
@@OliverPickard thanks again i will look for that!
Just been driving a new peugeot 508 around France and Germany, that has the worse ergonomics of any car I have driven... That and driving aids that hinder more than help!
I've only driven one of the lower model newer Peugeots and the singular thing I liked about it was the large speed display
