Locost V Haynes

Post by steveb » Fri Dec 02, 2016 8:10 pm

Locost versus Haynes roadster.
Has any one been able to drive one of each back to back. What is an opinion of each and why. What would choose?
I have considered starting a wide track locost based 7, until i came across the Haynes book.
I have the locost, Haynes, Tiger Avon books to browse for chassis inspiration designs.
I have seen Mc sorely larger designs.
Sourcing components esp front uprights seems to be getting harder to find.

Hi and welcome. I haven't driven either a Haynes or a locost but I am building a locost and my brother is building a Haynes. A Haynes is a little larger but not by much and the front suspension especially the steering rack is a little easier in that it uses an un cut escort rack. The upright issue is not that bad you can either throw money at it or get creative. Sierras cortinas and triumphs are getting hard to find. But my bother and I are both using Holden Gemini/ vauxhal chevvete/ Isuzu piazza up rights which are also getting hard to find but it is an option and is pretty much dimensionally the same as the sierra upright use the factory bottom ball joint a Honda civic top ball joint and escort tie rod ends and you will be laughing. Also lotus used the Vauxhall upright in the early esprits so it cant be to bad. Another option is Toyota lite ace but you will have to work out ball joints and suspension geometry for yourself. In saying all of that if I were starting again I would use triumph herald uprights with a spherical bearing from Canley's in the UK.
Cheers Pete.

the local wreckers seem to know when a part is becoming scarce and charge accordingly. 13 years ago i got a pair of cortina uprights, there were 3 front ends to choose from, less calipers. but escorts, cortinas, rwd toyotas were common wrecker fodder, times have changed. the industry seems to be focused on packing scrap into containers for export.
so i have a pair of ford, toyota liteace, mazda mx5 front uprights, all vary in size an weight. i started with ford as per book. then had hubs re-drilled to toyota pcd, found some 2pot but heavy calipers and rotors from a estima, redrilled to 4 stud pcd, alloy caliper adapter etc. then found the liteace with better scrub. i have a dx corolla diff, so want to run matching pcd and offset front and rear. trouble is with time you tend to learn more about what you are building, which changes your view on parts previously purchased. relibility or weight is also a big consideration, ie i bought an altezza complete rear end to use diff, hubs and axles. the diff and 1 hub weighs in about the same the complete dx diff end to end, but i wouldn't break the altezza diff.
I guess these are normal considerations when building or modifying.
thanks for listening.

I built the haynes, very strong, the book is easy to follow and there are some easy ways to make it stronger. I'd build another one if I had the energy....
Check my build diary.... yamaha powered 7.
Cheers,
Evan.

There are too many other variables to make a good comparison. They are all about the same if build by the same bloke with the same experience and same budget. Your second car will always be better no matter what design.
Yes, these parts are getting harder to find, but still come up, just not when you are ready. When you don't want the parts, several will come available. There is a RWD Hyundai that shares same design to the Cortina.

so having started a locost chassis and figuring out the plans aren't quite right and leaving a lot to one's own interpretation, then widening the chassis to create a wider front track left me wondering if there is a better option. the haynes is abit wider across the tub and the front suspension points and taller. After re-inventing the front for a 3rd time, that is cut mounts off and widen etc, the decision to start again was reached. "if it sucks, change it".
I have gained lot of experienced gained along the build, that cannot be replaced,
When i figure how to attach pictures, the message comes back as file to large.....
What is everyone else doing with pic's?
I'll go do some reading re-pic's
