[Land-speed] roll cage welding

[Elon]

To expand on Bryan's point a bit . . . you drop the cage through the holes,
to the garage floor. If the car is elevated you can usually drop the cage
that amount. The 3" diameter holes are sufficiently large enough to allow
you to tilt the cage from one side or the other. That gives you clearance to
finish that side of the cage and then you tilt it the other way. The cage is
then moved back to it correct location and the holes are welded shut with
sheet metal. The base plates should already be preformed to fit their
location. When you lift the cage back up, there should be enough clearance
to weld the tubes to the base plates before moving the whole thing into its
final resting place. Welding the base plates to the structure should not
have a clearance problem.  -Elon

Buy a good 3" hole saw and get a Milwaukee 1/2" drill. Drill holes, save
metal, (snip . . . )
