proper front uprights
 

I have got some nifty drawings for some nifty front uprights that along with some nifty wishbones may well be available very soon to fit the Roadster and other Sierra based kits as well as the earlier Ecort based numbers.
No prices as yet as the engineering type bod is still faffing about but they will come powder coated and wearing ali hubs....very trick very NOT ugly Sierra items oh and lighter;)

Please form an ordeley queue armed with as many creme eggs as you can stuff in yer pockets.

would the front lower be the same bracket fitment as the ones in the book?

any ideas on pricing?

Can do that yeah.....No idea on quids yet as engineering bod sussing the upright drawings I gave him hasn't got back to me yet hence my stupid jokes etc as I'm bored:o

Sounds interesting.

whats are the effects on the suspension geometry???
KPI? distance between mounting points, obviously scrub will be determined by tyre width and wheel offset but what wheel and tyre combination results in what scrub would be nice?

material?

sorry for the difficult questions but for me at least the answers are critical

tilly

Would these be a direct replacement for those of us who have already used sierra gear

Not heard back from engineering bod yet and as he has the drawings and I have a crap memory for numbers I don't know dimensions :o

They will be used on the new "beasts" yes "beasts" as there are 3 on the cards. 3 totally different to each other, 2 are not really new shapes but 1 is just mad, or is that me that's mad:rolleyes:

These sound very interesting! would be good if they were direct replacements for the Sierra items though without the need to buy new wish bones.
The Sierra uprights weigh a ton, surley an easy way to save a bit of weight.

Sneak preview so to speak clickety click

Looks good:)

They look very trick Mark!

They look very simular to the one piece bent steel plate with stub axle welded on type used by 80% of NASA autograss classes 5 7 8 9 10. will they be about £40 each?

Nowt is ever new and these are certainly far from new as I along with Marc Norden at MNR sports cars were given the drawings to make them way back in 2005.
I think Marc uses cast uprights these days on his damn fine cars so now I have found them again I want to have them made, I can use a lathe and twirl a tig but I prefer clean hands these days...:D

Look very cortina-esque.

Along the lines of yep and no silly off set mushrooms and wondering where the geometry is as it's critical it's the same both sides of the car.

Pinto Mustang II spindles/hubs
 

These are popular in USA on street rods. 1" taller than Sierra. Lots of parts available to fit, including of course, Wilwood brakes.

They are a far better option than using sierra uprights, just wish the engineering bod would hurry up now as I'm writing even more tripe than usual...:D

Any news on these yet would be intrested in a set

Well yes and no but what we have done is.......drawn things up all proper like and there will be a set of front upper and lower wishbones to keep the same track as using Sierra parts on the Roadster.

This has all been done with poota trickery to optimise (wow big word for me) geometry and ensure the parts work together and make for a dapper of a sports car as far prettier than the fugly Sierra lumpyness that used to be the bottom of a strut....;)

Set will comprise:
Pair fabricated uprights.
Pair upper wishbones
Pair lower wishbones
Lower ball joints as they differ from standard Sierra based Roadster.

Oh and will be powder wotsitted pink for much prettyness:cool:

Anyone else interested in this as would like some idea if worth going mad with it:o

I suppose interest will very much depend on price. If they look trick, and don't cost a fortune, then they should sell pretty well.
I suppose the stumbling block will be for people who already have front bones who don't wanna have to shell out on new ones.

I have been tad busy with daft t shirts buuuuuuuuuuuuuut should be in a position next week to sort prices etc out and hopefully some photties

Any news on this one?

Thanks

proper front uprights
 

Nice to see I'm not the only Portuguese person building a locost but yes good question is there any news on that uprights ?

I saw a flying pig from my window the other day and it had a perfect fabricated roadster front upright dangling from its tail :D

:D :D

Did it have a Triangles hanging from each ear & knackers .... If not, it'll wallow like a pig when cornering.
Not to mention, look a bit on the lardy side !!


Sorry, I'll get my coat :o :D

Was the pig eating toblerone? :D

I think I have re invented the wheel:rolleyes: :rolleyes:

Steady on lads -the flames dont need feeding.You cant keep the moral high ground by diving in the swamp

Come back Eric Cantona theres a job for you on here:D

Have a laugh instead Never keep the paint in the boot

On a serious note an upright according to the clever people should have zero kingpin inc. and produce zero scrub:confused: . that leaves just caster for self centering. Well the first two cant be done easily so the whole thing becomes a compromise. From the notes I have been reading if you require 5 deg. of caster you should have double that figure for kpi. So even if someone makes a special upright it will still be a compromise. To achieve any more adjustable parameters other than camber all that is needed is a fully adjustable top wishbone. There are loads of uprights out there that are suitable that tick enough boxes if you do a bit of research.

================... KPI ......... caster

Lotus Elise........................ 12° ......... 3.8° caster
Corvette C5, C6................. 8.8° ...... 6.5° caster
Pinto/MustangII/Wilwood... 11°
Ferrari 512BB............... 9 or 13°
ATS AFX Tall..................... 8°
Triumph Spitfire................ 7° ..........4.7° caster
Lotus Seven..................... 9° .......... 5° caster
Mazda Miata................... 11.3° ........ 5° caster
Ferrari F355................... 13.16°
McLaren F1...................... 9° ........... 6° caster ...... 16.25mm scrub

Dont know how much more toblerone I can eat:)

Strange, If I say anything remotely hinting that there are issues with how the suspension works I get slapped down and accused of having an attitude.

Read what you write, you are no more than pre school kids bitching over who is going to sit near teacher!!!

And Ronnie, I thought you were a moderator so meant to be unbiased or is that a case of pot calling the kettle black yet again?
As for that registered 7 you bought, I hope it's not the one that was for sale in Helston as that is a ringer and not legally registered as it uses a Dutton log book..

Heyo I can hear the Stukas firing up:D :D :D

Mark

Sorry if my post offended you mate :(

Long story short, I was bored & was just having a little fun :D

True I am a moderator but there was nothing in the job decription about not being allowed to have a sense of humour or irony !!

As for my new project mate " Wouldn't you just love to know " :D

Sorry, you'll just have to wait till you spot it on the road.

Will be real easy to spot, bright Red 7 & I will be the one driving with my head held high :p

Edited to add

Anyhow, this thread is getting a little off topic so back to the original question.

How are you getting on with the fabricated uprights & is there any news on when they will be hitting the market ?

I will be the one driving with my head held high



Make sure its below the roll bar:D

On the line of uprights found an excellent site with lots of cad pics and a lot of stuff with the haynes roadster in mind.Dont know if its been posted before but its very good.
