Chassis jig
As stated in a msg under the topic "Accurate front suspension" and according to relevant exchange of views with Rorty and others I started
this thread on the sole topic of designing and building a chassis jig suitable for the construction of any Locost Seven-alike and/or inspired, under
the following commonly used permutations:
a) Front suspension
a) 1. Cortina hub carrier (spindle) / hub / disc and caliper
a) 2. Sierra hub carrier w/ adapter for top rod end / hub / vented disc and caliper
a) 3. For the boldest, custom designed hub carrier to suit either Cortina or Sierra hub/disc/caliper (defying task!...)
b) Rear suspension
N.B.: I do not intend to even look at a rigid rear axle, be it Escort/Cortina/Capri or whatever; so I'll stick to IRS and my first approach
will be based on the Sierra back axle, ie, 7" (or 7.5" diff, half-shafts and drum brakes.
I'll try to incorporate in my design the possibility of using Scorpio disc brakes but I have not put my hands on one yet.
This means that my rear track is to be somewhere 1505 and 1530 and the front one must be more or less the same.
Of course the jig should incorporate all these possibilities as well as the rigid rear axles.
Enough for now, Rorty (and everybody else) your turn.
Cheers
Joćo
P.S.: As Rorty, Cymtrick or anyone else did not respond I shall soon publish (if img insertion works!...) a preliminary design of my jig.
I shall be working on the basis of an unmodified Sierra rear axle, Taunus (Cortina) Mk 4 front uprigths and a wheelbase ranging from 2210 mm (87 in)
to 2286 (90 in).
I presently have 2 possible drive units:
1. Sierra (Pinto) 1.6 + Type 9 gearbox
2. Taunus (Pinto) 1.3 + ?? 4-speed gearbox.
COMMENTS WELCOME

No way, it does not work.
Might it be my computer? Or my profile in Locostbuilders?

I didn't explain myself correctly: if I edit my msg and insert the image address it does not show. On a post reply the attachement / Browse
button is there and I can upload a pic from my disc.

forgive me if im being negative, and dont hesitate to correct me cos this is intended to be totally constructive.
but what is the point exactly??
are you planning on making several locosts of your own? or maybe send the jig to other locosters so they can benefit?
dont see the point in a jig for one car. or am i missing a point?
Cheers,
Russ.

Thank you for your input.
As you might have noticed there are almost as many building designs as there are locost builders in this site. Also, as has been pointed out by
several of our mates, there seems to be some "errors" in "the book" and, as far as I'm concerned, there are no design
guidelines whatsoever: wheelbase, tracks with Cortina or Sierra wheel assemblies, etc...
You start building a "book" chassis, then weld some brackets, fit the "book" wishbones and you will finish getting
"something" indeed: but what?
That's what I wish to establish previously (not know afterwards) and to be sure that my build follows the design the first thing is to be sure
that the hubs, discs, uprights, etc... are in the correct position and then mount the designed wishbones and then the suspension brackets have to
be there.
Therefore I would build such a jig even for only one Locost build. However he have some 50 members of a "to be" Locost Se7en Portugal Club
and only some of them have already built their chassis; the others might use my jig to build theirs.
The jig will be adaptable as much as possible (see my first post in this topic) for wheel assemblies and even different tracks and / or wheelbase
within a certain range.
Does this answer your doubts? I hope so, anyway feel free to keep posting to this topic I'll be glad to answer.
Cheers
Joćo

I use solidworks personally; much quicker, various other benefits - and cons no doubt too, but it works for me for things like seeing for myself what
wishbone design and location we're going to need.
