Building a cage

OK so i am putting a bit of a home made cage effort into the S12 silvia i have but it is not fitting that well and i was wondering what is the correct method of securing the tubes to the floor?
Do you put a plate on the bottom of the tube and weld it to the floor or do you put a plate on the bottom of the floor also and bolt it right through the 2 plates?

Post some photos up so we can see where it's going wrong.

With my SD Cage, there were 4 box plates 2 shaped to butt to the inner sill/floor a few inches back from the A pillar. Another pair behing the B pillar and a pair of flat plates with a 90o top flange that sit on the top of the rear suspension turrets.
These were fully welded in position. The sill brackets have two tapped holes (clearance hole in the plate and a full nut tacked behind) in the top face and a single tapped hole in the inner face. The end of the legs have an angled piece welded to them with corresponding holes for the bolts to fix each leg to each plate.
The rear two legs have flat plates with three holes, two above and either side of the tube and one below. These are fixed by drilling through the turret and fixing with bolts & nuts.
HTH or makes some sense
I'll try to take some pics tomorrow.

I'd weld a plate on the cage and re-enforce the floor/shell sections you are going to weld them too.
The MSA say use 3mm plate as a minimum.
There is also a minimum requirement for the surface area of the feet/plate but I forget what that is.

Have to make do when you are not on a huge budget mate, just because you make something yourself does not make it a bad thing. A lot of the projects on here are guys having a go themselves.

It is not going wrong mate i just needed a bit of advice for fitting as have never had experience of doing cages before.
