Alternative hubs/uprights
Hi all,
This has probably been asked before, but I can't find it in the history so..
Apart from Cortina Mk 3-5, are there any Ford hubs I can use instead. Can I use Sierra ones with a suitable insert at the top (as sold by Robin Hood)
or does this alter the geometry at the front end, what about RWD Escort or Mk 2 or 3 Granny bits?
Any help app' as I want to widen the search for these bits a little (someone has hidden all the Cortinas round here!)

Yes you can use Sierra ones. Adaptors are available that allow you to use the transit top ball.
Search through the site and you will find details of suppliers.
If you really want Cortina bits you can get complete front uprights and hubs for around £35 each from
www.auto-recycle.co.uk

You will need to use shorter top wishbones if you use Sierra hubs, and I'm pretty sure that Cortina lower ball joints are NFG for Sierra hubs. MK
drill Sierra hubs to take maxi balljoints

Tyey're still about if you look around, check your local "Yeller" or "Freeads" etc.
If you're feeling flush, check out ebay etc.

Just another question on the same Sierra hub subject, if a Maxi bottom ball joint is used rather than Cortina, does the hole need to be taper
drilled.

Thanks John.

Another annoyance with using the Sierra hubs is that you can't use standard length wishbones. The offset between the centre of the top balljoint and
the bottom is different from the Cortina.

All this stuffing about with heavy, over-engineered (for a light Locost), mismatching car parts!
Surely, in the great Locost tradition, you should make your own uprights.
The advantages are numerous:
1/ Extremely light weight.
2/ Uses easily replaceable trackrod ends or Rose joints.
3/ Optimise the scrub radius for any old wheels you want to use.
4/ Use any caliper you want, including really light 4 or 6 pot bike calipers.
5/ Pick your own steering arm length to quicken/slow the steering.
6/ Easily made in your garage from cheap materials.
7/.....I'm too modest.

Rorty, may I on behalf of some of the rest of us, express an interest in your home-made uprights. Perhaps we could prevail upon you to tell us how you
do it?

Please enlighten us to the construction of your uprights, they look super cool. Plus the discs look bizarre, I'm guessing they're off road, trials
motorbike maybe, am I correct? The only disc I've seen like that before were for trials mountain bikes so they could take a battering and most
importantly, looked cool. I used to have some on my push bike, till it got stolen 
Do motorbike discs/calipers work on cars? I would have thought there would be heat/strength issues with the added weight?

Before I go any further, I think my uprights need a short introduction. The car weighs 390kg, and frequently hits the ground from heights up to 8 or 9
feet while traveling at about 60mph, when coming off jumps.
I have used everything under the sun over the years, including Torana (Australian version of the Viva) front uprights, and I even bent one of
those.
My uprights are about half the weight of those Torana ones, yet I haven't had a single problem with them.
They are made from a turned stub axle, and two lengths of 3mm RHS. One bit for the steering arm, and the other bit has a V cut in it, then bent to the
correct angle and welded.
I use Rose joints in the horizontal plane to give almost unlimited travel (in reality 14"), and turn some ball extenders to increase the angular
limit of the joints to 48 degrees inclusive.
The cheapest way for the Locost would be to either use the Rose joints in the vertical plane, or use two Transit rod ends.
Again, to keep it cheap, you should be able to buy Cortina/Granada (or whatever you fancy) stub axles from any trailer parts place or motor factor,
then just turn a spigot on the end for welding through the upright.
Obviously that's over simplifying matters, but you get the idea. The important bit is to get the geometry right. Now I'm only too glad to help out
with drawing the jig and the upright itself, but I can see this blowing out ....some may want vertical Rose joints, some horizontal, some for Escort,
some for Granada etc. and that's not even going near the various caliper permutations!
To be honest, I would rule out the horizontal Rose joints, as the ball extenders are quite hard to produce by NC...read expensive.
If someone wants to start a poll, and come up with say 4 or 5 different popular models, and can supply me with the various dimensions I need, such as
ball to ball (vertically and diagonally), and distance to disc face etc, then I'll do the rest for free.
If on the other hand someone wants different hubs, bike calipers (thin discs), different scrub radius for those sexy Peugeot wheels etc etc, then
I'll charge them my going hourly rate, which, with the conversion rate the way it is at the moment, is pocket money to you lot!
quote:
Plus the discs look bizarre, I'm guessing they're off road, trials motorbike maybe, am I correct?
I design all my own discs, and have them laser cut. That way, I can maximise the disc size to the available wheel well clearance, depending on what
calipers I'm using. The "bizzare" shape has several functions.
1/ The discs are as light as possible.
2/ They stay cool.
3/ The outer "cauliflower" profile actually cuts any debris off the face of the pads.
I have never warped one, even when driving on the roads, when we go "bush" for a week end. If they did start to warp, they are a fraction of the
cost of a regular car disc to replace.
Fastenuff, those uprights you illustrate are fine, and I suspect they are a universal upright i,e, for front/rear, drive /non-drive use. I have made
some like them for a 4WD project. They are certainly strong enough, probably a little heavy, and quite a bit more difficult to jig and weld.
Cheers, Rorty.

Rorty,
I think I would be safe in suggesting that the most popular fitment would be Sierra hubs to cortina dimension uprights. Also would it be possible to
see a few pictures of your upright on its own? Finally, and less related, are your wishbones powder coated or painted? They look very nice either
way.

OK, I'm happy to do those, though I'll need you, or somone to provide some basic measurements. In other words, Cortina upright dimensions, and
Sierra stub axle dimensions along with the relative position of the Sierra caliper bracket.
If you want to email me, I can let you have a requisition sheet with all the relevent blank dimensions for you to fill in.
quote:

I'll have to do a bit of digging, I just pulled that other image off my web site. Give me a minute, and I should be able to come up with a pic or 3D
drawing.
quote:

I paint everything. Powder coating isn't tough enough, and can't be touched up.

Sure. What's the Indy based on, Cortina or Sierra? Same as above, if you contact me, I'll email you a sheet to fill in with the measurements.

All donations gratefully received.

I have uploaded a few pics of one of my front upright/hub assemblies to the Photos archive. The upright is for use with Rose joints mounted
horizontally. It would be virtually the same for use with say, Transit tierod ends, other than the Transit rod ends would obviously have to be
mounted vertically.
I have built them with VW Beetle tierod ends in this fashion. Worked beautifully.
Cheers, Rorty.

Has anyone considered Metro hubs?
Before you all laugh, you get ball joints top and bottom that could be clamped, ventilated disks (small) and 4-pot calipers. Might be worth
investigating.

I'm not laughing!!!!
I have changed to a chain driven diff which now requires metor drive shafts - the logical link is also to use metro hubs [trying to source now]. this
is for the rear though.

I ve put in some strange brainwaves into this subject. Taking Terrapin ideas with sierra parts. The results were some odd models for fornt uprights,
as seen in the photo section. height simular to the cortina part as is the angle.
Comments would be welcome
