    That was my thinking.
    The car will probably be built up to a point to pass the IVA and then modified and "finished" to my liking.

    Don't know a thing about it but I look forward to the build thread. :D

    Before you start a new project though, did you finish the massive CNC router in your avatar? I don't remember seeing any further than a load of chopped up box section. :scared:

    Some of the frame is welded but I've not really found my Mojo for it. Part of the problem is that has now become work instead of a hobby. Plus the fact that we now have 3 full size Tekcel routers running there is little requirement for it.

    One of the reasons for this project is to motivate me to get my metalworking area 100% finished and up and running and to get me back into the swing of proper project work.
    Once that is happening the CNC with probably just "happen" in the background. All the of the hardware is sat there waiting for the frame to be finished:

    Have a look at the Haynes forum , I think there are a few mistakes in Chris Gibbs book that are corrected on the forum , also have a look at LocostBuilders , loads of help on there . Most of all, enjoy it

    If your going to build the Haynes roadster from scratch google it first

    When I raced kit cars the original plans made the gearbox house the wrong dimensions

    A lot is changed in the SSC plans to accommodate the MX5 running gear.
    I would build the basis of the frame and then finished with all the main components mocked up in place.

    The Haynes way seems to be build the frame in its entirety and then drop the engine and bits in.

    Watching with interest as have wanted to do something similar.

    Have a rough zzr600 in the shed that could be a little donor for something.

    I was thinking of GSX1000r power unit but even an older one is going for £1k upwards and there’s extra bits required for reverse etc.

    A running MX5 can be had for £400 which supplies engine, gearbox, prop shaft, diff, axles, uprights, brakes, loom, clocks, steering column etc. Really only need coilovers and steering rack to complete the rolling chassis.

    And I think now a reverse gear is part of the iva also so adds a fair amount to the costs.

    But would want one for field work.
    The zzr600 cost me £120 for a project.

    @Barlidge is building a fat BMW V8 Haynes, I have three on the back burner ATM. Two for a friend and I to wreck around a track with a spare rolling chassis to cover the inevitable, both will be road registered. You can actually build whatever you want and register it, no donor car is necessary, you just need to keep receipts for everything. Worth going for an older engine so you dont need to comply with emission`s ( cats and all the malarkey)


    I am going for a morris minor engine, thats what the man said it was. With ali heads,water pump,manifold and a few other tricks its lighter than most ford four pots.

    Morris minor engine will be dry sumped so snug under the bonnet :thumbup:

    HD 4 core landy rad should keep it cool.

    A really quick escort rack powered by a corsa power steering unit, should disguise my lack of talent when it all goes wrong in the corners.

    And some pretty bits

    Just release mine from its clamps on Monday evening, only taken me 7 years to get this far and I went a bit off book with the design to accomodate the V8. within 48hrs the garage it was built in is now in pieces and in the garden of my new house ready to be rebuilt.

    Go for it. I started on nine 10 years ago. Only reason it's not finished is House, maridge, child, milling machine rebuild, refurbishment of 2 other houses building my own garage to finish it in. Oh and more machine tool refurbishments!
    The good thing is I now how everything in place to restart it this year.

    Thanks for all the inspirational pictures of your build guys.

    This might be a 6 month or a 0 year build. I not really bothered which, it’s really about the process for me.

    Same here. I'm going a step further with mine. Now I have a lot more machinery at my disposal I will be making my own throttle bodies, inlet manifold, exhaust system, fuel tank etc.
    The engine management will be via Megasquirt.

    For plans and CAD of the book chassis take a look here http://sevenesque.com/intro/

    or if you fancy something waaay more complicated http://midlana.com/

    I agree on the process - selling my Sandrail as it's been working for a couple of thousand miles and I'm bored !

    Thanks for the links, there’s so much info out there is hard to find a starting point.
    I’ve got the Locost build book and the Haynes sportster book as starting points.

    As people have said these aren’t step by step guides but I’m not really interested in that as I can just buy a Lego set for that sort of experience.

    This will be my own build based of all of these starting points. The good thing about the SSC plans is it gives the suspension geometry for the MX5 uprights.

    I plan of using most of the stock MX5 parts for the initial build and then post IVA probably adding a turbo with custom engine management.
