    The deal Lonnie is that you haven't yet mastered out of position welds on round tubing. Your first question is enough in and of itself to see you don't yet have the experience for a chassis. You won't believe it but here are many, many others that came before you trying to do the same thing. You say you can't go more than 90* on piece of tubing. That, you will need to practice. Your teacher may have had that experience but at this point you don't. Not yet, anyway.

    The couple of guys like Sundown (who certainly knows what he's doing) and Old Skool make good points, not on assumptions but on what you've actually posted to the thread. You asked the question in the first place when before starting this project, you should have known. Your choice of machine is a bit suspect as well. It's a fine machine, but this sort of work is usually done with a minimum of a 180 amp class machine. That's not to say you can't do it with the MM140 but it's not the best tool for the job. An MM211 or a 252 would be a better choice. Then you state you can't do out of position rounds very long. Nothing wrong with learning, but those three things alone make others with more experience question the wisdom of tackling such a project at this point.

    Most of these projects never see th light of day anyway. The builders lose interest or get to the point they are over their head and it get abandoned. Don't get me wrong, I'd like to see your project succeed but at this point you still have more learning to do.

    Good luck!

    Yup, I appreciate what a challenging task it is for sure because I've now just about done it. I'm closing in on a finish in the very near future. All the major structures are complete, but there is still some work to do.

    I've just proceeded slowly and done lots and lots of test coupons as I've encountered new welding situations. The chassis is a custom version of a sports car based on the Lotus 7 roadster. I built a rotisserie to rotate the chassis as I did the final welding, which allowed me to turn almost all the welds into flat and horizontal welds. It's primarily RHS in 16 and 14 gauge.

    Cheers,

    Lonnie

    Nice work. I applaud you for keeping at it and ignoring the critics. It seems you are doing nice work. And I am sure you have learned a lot over the last year or so. Are you following a set of plans or working from your own design?

    Default Welding Tubes on Chassis - Need Strategy

    I agree it is very nice work. I would also like to see how your welds have progressed (considering this is a welding forum not a car forum). Overall looking good.

    Smile Australian Miata Based Build

    Here is an Australian build with a tremendous amount of good quality detail photos that you might find of interest.. lots and lots of good detail stuff..

    http://www.locost.ozcarnut.com/html/chassis_photos.html

    they also pay a lot more attention to crash protection and torsional ridgidity..

    so they add a fair amount of additional bracing...
