I've loved the Ariel Atom ever since I saw it and I've wanted one ever so badly. <IMG SRC="http://www.fiero.nl/forum/smile.gif"> Well yesterday I was walking past our clean scrap dumpster and saw 10 or 15 5-6 foot long square steel tubes 3/16 by 1.5 or 2 inches square. I asked my boss and he said take em. Sweet!!!! So I have somewhere between 80-100 feet of tube. Now I want to build my own tube frame automobile somewhat like the Atom. I know ill have to build the chassis first and foremost but not sure what software to use to see if the chassis will hold up. So I need some recomendations on programs. Is it possible to do it by hand and just make it stronger than what I think I need? I want to use a 350 with a manual trans not sure if I want 2 seated or just 1 seat, I also want the front suspension to resemble a pagani zonda. I might be somewhat in over my head but challenge is what I love so if you guys have any pointers please share them. I will post pics of the diffrrent aspects I want------------------ 1987 Black GT Custom interior with Mr. Mikes seats Series 1 L67 W/ 5 speed getrag! 1988 Formula-GT <IMG SRC="http://www.fiero.nl/forum/smile.gif"></TD></TR><TR Class="HTMLAltCol1"><TD valign=top>lurker</TD><TD>go for it. i want to build a tube-frame mid-engine 2 seat geo metro, but it's on the back, back, back burner.</TD></TR><TR Class="HTMLAltCol2"><TD valign=top>TommyRocker</TD><TD><A Class="HTMLBodyLink" HREF="http://www.locostusa.com/forums/" TARGET=_blank>http://www.locostusa.com/forums/</A> <A Class="HTMLBodyLink" HREF="http://www.locostusa.com/forums/viewtopic.php?f=36&t=9904&hilit=ariel" TARGET=_blank>http://www.locostusa.com/fo...6&t=9904&hilit=ariel</A> Do it.</TD></TR><TR Class="HTMLAltCol1"><TD valign=top>87antuzzi</TD><TD>Catia, solidworks, autocad, ironcad, delcam....the list is endless on what you need.

Then you can design a frame to match. Unless you think you're qualified, don't spend too much time trying to use software to "see if the chassis will hold up." You tell the software what to do, and unless you know what the loads are, it can't help. Just go overboard with tubing, and take your chances. The only way to see if you'll be in over your head is to jump in and see if your feet touch the bottom. Good luck we're here to help.</TD></TR><TR Class="HTMLAltCol1"><TD valign=top>ls3mach</TD><TD>I bought some 1-1/2 3/16 tube yesterday. It is $2.15 my cost. I typically mark something like that up about 35%. You want to take on the task of building a car because you got $300 worth of steel tubing? Typically when I sell tubing for chassis, I sell Chromoly. I don't know the tensile strength of the steel you are using, buy I build the racks for my pipe trucks out of 3/16 wall square tubing and have had great luck. I can't give you a load amount as it is balanced over 3 points. I don't mean to sound discouraging, but that wouldn't be my choice for building a car that is going on the street. Fine in you want to build your kid a go-kart (except for the weight). Just my $.02. Not to hijack your thread, but I have some 3/4" .065W 304/L instrumentation tube that I am willing to let go cheap. It won't hold a ferrule, but is super strong if you wanted it to bear a load. It has a bright annealed finish.------------------ I got bronchitis.

Steel is so cheap, I would make sure I got exactly what I wanted. I would think EVERY other part is going to be more than the $300 in steel that he got, which might not even be strong enough or the right lengths. The project sounds cool, but I would get want a bigger head start than that.</TD></TR><TR Class="HTMLAltCol1"><TD valign=top>heybjorn</TD><TD><TABLE BORDER=0 WIDTH=90% CELLSPACING=0 CELLPADDING=0><TR><TD WIDTH=10%> </TD><TD Class="QuoteBackgroundTable"><TABLE BORDER=0 CELLPADDING=2 CELLSPACING=1 WIDTH=100%><TR><TD Class="QuoteTopBar"><CENTER>quote</CENTER></TD></TR><TR><TD Class="QuoteMsgBox">Originally posted by Celthora87GT: I want to use a 350 with a manual trans not sure if I want 2 seated or just 1 seat, I also want the front suspension to resemble a pagani zonda. </TD></TR></TABLE></TD></TR></TABLE> Just an idea, but I have always wondered why people like the idea of the locost type of vehicle but put so much effort into the ultimate design, that is, a design which maximizes suspension performance to the nth degree. Is this worth the effort for a street or street/track day car? A Formula 1 car, yes, but for a street car, light weight and wide tires appear to be the biggest performance factors. Where on the street can one use all the horsepower and cornering capability we can design into a vehicle? Build a lightweight car using as many production components, steering, suspension, brackets, and so on, as possible to keep the cost down. If cost is no object, fine, but my wife says she still has to buy shoes and pants. </TD></TR><TR Class="HTMLAltCol2"><TD valign=top>Zeb</TD><TD><TABLE BORDER=0 WIDTH=90% CELLSPACING=0 CELLPADDING=0><TR><TD WIDTH=10%> </TD><TD Class="QuoteBackgroundTable"><TABLE BORDER=0 CELLPADDING=2 CELLSPACING=1 WIDTH=100%><TR><TD Class="QuoteTopBar"><CENTER>quote</CENTER></TD></TR><TR><TD Class="QuoteMsgBox">Originally posted by heybjorn: Just an idea, but I have always wondered why people like the idea of the locost type of vehicle but put so much effort into the ultimate design, that is, a design which maximizes suspension performance to the nth degree.

Good suspension design makes the car much more "driveable", and makes for better subjective handling. Plus, suspension designed for a car weighing twice as much won't work right on a much lighter, smaller, car. If, indeed, "Locost" is your only goal, use donor parts as far as possible. Also, the cost involved in actually fabricating the few suspension arms is not much higher than buying the donor parts.</TD></TR><TR Class="HTMLAltCol1"><TD valign=top>Zeb</TD><TD><TABLE BORDER=0 WIDTH=90% CELLSPACING=0 CELLPADDING=0><TR><TD WIDTH=10%> </TD><TD Class="QuoteBackgroundTable"><TABLE BORDER=0 CELLPADDING=2 CELLSPACING=1 WIDTH=100%><TR><TD Class="QuoteTopBar"><CENTER>quote</CENTER></TD></TR><TR><TD Class="QuoteMsgBox">Originally posted by ls3mach: You want to take on the task of building a car because you got $300 worth of steel tubing? </TD></TR></TABLE></TD></TR></TABLE> It's what I refer to as a "precpitating event".

I will base it off of know things and things I can get easily and quite cheaply I.e. fiero brakes and hubs and knuckles. I will use thicker better metal for the under car main supports, I will have the sub structure professionaly welded. I have thought about this a lot I've just never dove in because I didn't know where to start. This has given me some guidence on the first step. Also it will be awhile before I even get cutting.
