I trying to build a rocket from scrap materials i find in the junk yards, sure the rocket is going to be very crude but i'm crossing my fingers to a successful launch other wise i'll be the first civilian to launch his corpse into space.

Way too heavy

I will teach you to build a new type better rocket frame.. Get a hold of some Kevlar material and depending on size and power of needed rocket, you'll need to make a cardboard tube mold..To wrap Kevlar material around in a few layers changing direction of material and applying a fiber glass resin between layers and rolling over them with a spur roller to keep bubbles out...( Then let all dry or set up ) If you can get a hold of some carbon fibers to also mix with resin would be even better to add over Kevlar material layers...( Now it's time to build a thrust engine and add to rocket...( Solid rocket fuel or liquid ?) Don't forget to get some tooth picks at the store to past out to friends whilst rocket is being launched....

The strength to weight ratio for rebar is pretty bad. It is relatively soft and weighs a heck of a lot. You are much better off with a tube, preferably of something strong and lightweight. Aluminum would be a good choice (unless you have carbon composites or titanium laying around in your junk yard...).

No successful rocket has ever been made from steel or iron, and there are good reasons for that---the strength to weight ratio is just too low.
Almost all early rocket pioneers suffered repeated total failures prior to any success. Consider that before you light the fuse.

The rebar will reinforce the space frame, but it also weight in down, so an aluminium will be better.

I think you need to step back from scrap materials. Structural weaknesses will cause severe problems. Use fresh new materials and find something lighter. These people (private sector) here succesfully built and launched a ship into orbit which carried passangers and payload. you might want to research them. look at their facility too. it does take a bit of money, research and math to pull it off.

NO,you may not deliver a rocket into area without the authorization of the government in specific no longer in usa.this is unlawful to launch a rocket int area.yet no government tec can detect a small rocket yet while this is a sizable one they'll probobaly attempt to shoot it down.the rocket ought to pass everywhere.it would pass to the white abode or the pentagon and blow up there.

Launch your dog instead of you first, and see what happens to him.
As for re-bar, well, it would depend on how the frame was constructed and how well it was welded. You would probably need a structural engineer to look at it and calculate the stress that it could withstand.

Reinforced Rebar? that is like saying Reinforced Reinforcement.

Structurally it might work, but rebar is very heavy. You'll need extra thrust from the engine(s) to compensate for high weight loading.

waste your time in something else than making a rocket if u r beginning with re bar for framing
