| So heres an illustration on v-groove weld. take the pipe/pipes you want to weld, then grind a bevel around the edge. 
then weld in the V to join the metal and grind smooth if you like.

| chilebean....awesome...thank you. I thought that was it but wasn't too sure. thank you again for your knowledge and pic! dave...i did say square but it's just for the bottom. take a look at the Awesome-Aussies Creation. 
this is what I plan to do...less the front axle/controll arm mount thanks to your ingenius idea. the only square tubing will be underneath me. the rest will be round. I based my wood mockup frame on this great piece of work...which is the closest match (if not exact) to the vehicle straight from the Wayne Foundation Applied Sciences dept.
...does it come in black?

| Not to be a downer but I think you should stand those tubes up. It would be stronger. And since your not on a frame jig be sure to constantly measure and make sure things are square and level as you go along. It's cool to see your starting on the metal. That makes what, 3 tumbler builds now  out of curiosity how big will your tumbler be? length, width, ect.

WAHOO METAL! Hey Conrad did you ever fix those measurements that you were talking about a while back towards the beginning of your build, i seem to remember you saying you were going to make it a tad lower, and wider, or something like that.

| bean, no downer...I think it'll be Ok. i will have a sheet welded under most this bottom portion of the frame so that should strengthen things a bit. It turns out that the total length will be about 15 feet long and 6 1/2 feet wide (less the body panels). I definetley won't be doing the complete frame on bricks. You said it bean, I'm measuring 10 times and cutting once. when I get started with the tubing i will no doubt build the jig. those I beams are pretty pricey. i need 2 15 footers at about $350 each. I've taken a lesson from the pages of BWD's Rumbler Fabricators and realized that it will be impossible to fabricate this vehicles tubular chassis without a jig. Again, what you see here is only the bottom. and yeah Shagg, the adjustments have been thought out and made. what did Pontiac used to say?....W-I-D-E-R is better.

| Hey Conrad, Ok I don't want to come across as a downer. But.........Chilibean is right....Think of building it with wood 2x4s you would want to build it with the 4" part going up and down and a big heavy x-tube from corner to corner. The load factor on that floor is critical for strength. That's why the round tube is so nice it displaces the load across a circle. And even the Aussie one could and should have been made with round tube. One interesting thing about load and stress placed on a frame is the the load will transfer from one place to the weakest place. Imagine if you had forgot to weld a joint even if it was not in a critical point the load and stress would move to that point. Your floor is like the safety capsule of a racecar and it has to be strong strong strong.... Ok thanks for letting me say that and I want to say I am 100% behind your efforts. I hope you don't mind me posting a picture of my 89 floor to show you some cross bracing. But even in this application the outside of the Cadillac box frame is where the stress is carried. Also another suggestion, don't limit yourself to metal shops for materials checkout your local metal salvage yard just because its used does not mean it's inferior. Metal has a long life and salvage yards are a great source of used metal materials. I am planning on using a titanium fan on my 89....Yeah from a salvage yard...How much do you think that would cost at a retail center...Your Pal BWD

Thanks for all the info and advice. this isn't a downer. everything can always be better. I mean is this really going to be THAT weak? is there nothing that can be done to strengthen it? My neighbor who rebuilds cars ( specifically mitsubishi 300GT's ) said it'll do but the other way is stronger. Not that i'm settling...Any ideas on what I would use to make this stronger the way it is? I always ALWAYS appreciate the ideas and advice. Don't Stop....
