good idea. shouldnt i have drilled those holes before hand though? so the outer tubing is the only one with a hole? or should I drill clean through from one side to the other and weld a piece of round bar in there tieing it all together.
Drilling before hand would've made life easy, now it'll make life interesting
With a bit of patience, you can drill through just one layer. Don't drill right through; the holes will be a pita to fill.
Top & bottom would be the best place, that's where most of the stress will be...

After i sand blast metal or sand i always put a coat of primer on it because it will start to rust over night where i live anyway...
