    People make frames here in New Zealand all the time in their sheds, I have a bucket racer with a custom frame made in Nelson and it goes very well thank you very much!

    I don't think it is too ambitious of a project!
    thanks, and yeah i'm inclined to agree with you

    but finding someone with experience getting this sort of thing road legal is proving difficult... well i haven't really done much looking sorta hoping someone will see this thread before i start the project

    http://www.hotrod.org.nz/ talk to someone from here. I think you would benefit from a document called "the hobby car manual". I think thats what its called.

    I think we could be friends

    I'm keen on making a bike myself, only I don't have any mechanical skill. Like to think I can draw nice looking bikes though, it's all I did in graphics class last year.

    What course are you doing? What prerequisites do you need for it? Since I was complacent last year (like spending all my time drawing bikes) I didn't achieve uni entrance. I like the sound of making fuel injected 2 strokes.

    I was simply thinking of getting a MIG welder at home and making up a classy looking bucket first of all, then build up a bigger machine when I become more serious. The other day I drew up what I think is a unique orientation for a rear shock that's really only different for the sake of being different but I'd like to give it a shot.

    i'm doing a degree in engineering at the university of auckland, which basically requires a merit or better average in NCEA 7th form calculus and physics, or a B average in a science degree (which from 2009 onwards will finally require you to have some prior knowledge in you field of study) from which you may be allowed to swap over into engineering. myself i only just scraped into engineering after cruising through highschool and wagging half of 7th form. after the general engineering first year my marks were good enough to get into mechatronics, which is a combo of mechanical and electrical engineering with a bit of extra computer systems/software engineering thrown in. (very glad i didn't sigh up for the uni formula SAE team; as fun as designing a racecar sounds and as good as it may look on a CV, i've got enough to do as it is!)

    we have to do/learn all the welding/workshop stuff as part of the degree on top of all the papers we're required to do, along with 800 hours paid employment comprised of 400 hours sub-professional (ie office work) and 400 hours doing as you're told (ie operator/technician/fabricator). then there's 4th year research project and all the projects as part of your courses (right now i should be designing the chassis for a robot my group intends to build)

    so, contrary to what many people who don't know any better believe, we aren't entirely hopeless when we leave uni and actually have a fair bit of "real world" experience plus the knowledge that some take decades to aquire - bonus is that there seems to constantly be different companies trying to employ us before we've even graduated; so finding a job in NZ (or overseas) really doesn't seem to be an issue.

    of course making a fuel injected two stroke that works, and works well, actually requires alot of maths/modelling etc etc, or atleast a fair bit of time/skill. to make a chassis again can simply be a task of welding metal together and hoping it holds - which will be nigh on impossible to get road legal - or my planned approach of modelling and anaylising it so i know that it will be strong, perform well, not break in half after a year or so from fatigue, and thus be road legal-able.

    the stuff i've learnt since starting at uni is simply amazing, and i'm ever more painfully aware of how much i'm yet to learn, and even the stuff i won't get to learn (civil, chemical/materials, and biomedical do all sorts of things i'll never encounter). it takes a hideous amount of time and effort (and money), but it challenging, interesting and the student lifestyle is fun - and unlike many arts/philosophy students i know, i can actually directly use this degree to start a well paid career that can take me anywhere in the world


    if taking the academic path doesn't sound like you, you could consider an apprenticeship: earn as you learn, will be a master of building stuff, but afaik won't be set up very well for professional design work.

    I am into learning more, I'm not your typical metalwork slacker as everyone now thinks I am since I'm at Weltec doing car painting (which is an awesome course, see attached photo).

    Think I'll just aim at welding stuff together at home.

    It's not that scary putting together a bike. As others have said talk first to get the right info; Ixion metioned Frosty has Alex Gee's contact details. Google the LVVTA website for info; they also have a list of certifiers as well. Talk to Classic_Zed as well. Make sure you can get a welding certificate for the frame.

    Then work out what you would like to do and what you can actually do given your skill set, experience, and finances. The financial aspect of it all is the one that you really need to nail as costs can start to get away from you. So make a realistic budget which means understanding component part costs.

    I got my bike through the LVVTA process ok. Others on here make their bikes too.

    Good luck to you, it sounds like an awesome project.

    heheh, yeah myself i was one merit short on the calculus side and barely met the physics requirements due to my not deciding what to do until the last third of 7th form. luckily for me i did well in all other subjects and so they made me do this 2 week maths course to bring me up to speed. turns out the 550 student intake limit doesn't actually limit anyone; they struggle to "lower the bar" enough to admit students like me to reach ~500 students, then take in the science kids. just so happens that once at uni i thrived - it's a much better learning format/environment than highschool - and got into mechatronics (which actually has an intake limit, and alot of people didn't get in). i still have trouble with the maths after slacking off at highschool, but everyone has trouble with the maths bar the maths whizzes who then struggle with everything else

    thanks - yeah i'm trying to get the all right info before i start to save alot of future headaches, will google lvvta later tonight

    Mint, might swap over if lightning strikes and i want to do engineering, up ta stage 3 maths with Stage 2 chem & phys

    Ill donate a KLR frame for you to f with

    right, so reading up on low volume vehicle certification, i now know alot of bikes on the road are actually in need of lvv cert after all the aftermarket fairings, subframe swaps, wheel/suspension swaps and mufflers "noticably louder than the what the vehicle would have sounded like originally" - or is all that just for cars?


    now i was hoping to just have a page with "in order to build from scratch you have to jump through these hoops backwards, and those hoops while signing a cheque"

    as far as i can discern, this really is a case of just finding the guys qualified to certify what i need certified

    then, if what i want to do isn't covered by their standards, the certifier goes and talks to lvvta about it....

    i'd prefer it if there was a pdf written in plain english (rather than lawyer's jargon) with set standards and and explanation of the process for a scratch build etc etc, but i suppose i've gotten enough info from the site and if the certifiers are reasonable guys i won't have any problems. of course the last thing i want is another set of laws made by idiots down in wellington who have no idea what they're on about.

    and lucky for me, of the two certifiers in auckland qualified to do bike scratch builds, one is within 10 minutes of my place

    thanks for the offer but i doubt they'd certify a pile of rust

    Cant be that hard check out this mini chopper spotted in auckland regod as a 2005 and if your wondering the head light is held on by cable ties. what cracked me up was the large lock round the front wheel like your going to steal that even crims have standards. looks like frame was an old RM now with a 110cc throwin at it.

    Yep, that is about the gist of it. Speak with a certifier first before you start, it will save you a lot of tme and grief.

    Well that's given me a glimmer of hope. Since I did well in physics (it's amazing what you can do when you actually study) there might be a course I could do to then get into engineering.

    Then I'll be able to make a 2 Litre V4 2 stroke made from 4 CR/KX500 cyilnders

    LOL

    yeah not really what i'm doing, as i'll be building my own chassis rather than getting some bike parts and cable-ties and assembling.

    wasnt expecting that your build quality would be that poor it was just an example of how bad they can get, And they they complain about unsafe vehicles on our roads when they let out.

    Ive had a bit to do with getting vehicals certified for the road over the years. Ive mainly builts truck chassis and hot rod chassis but Im assuming the process would be similar.
    Heres what I did.....Discuss your ideas with an engineer who specialises in the area your going to be working in...in this case...low volume.
    Some of them are able to take your design and work with it on their computer and show stress points and possible changes for strength etc. This can take alot of time and you have to have a pretty good idea of what you want from the final finished product. BUT they can help and in the end its worth it because thier final word is considered to be the shiznit.
    The building is the easy part.....as once you have the basic certified design any certified welder can make it up (or do some courses and get your 4711 welding cert in a couple of positions and do it yourself, costs about $180 per position and is valid for 1 year...then do it again and its valid for 2years)....then its off for vinning with the required associated road worthy cert and all is good.
    I have built, chopped and redesigned chassis for cars and trucks capable of carrying upto 80 ton and never had a problem so long as you involve the engineer from the start. There are some good ones and some real shits to....so be aware. So long as you follow the laws laid down and the advice of the engineer I can't see you having any trouble.
