That was the best answer I have ever received to a question. Thank you.

Now for another question: I have a small air cooled welder at my house that can (at the moment) only weld steel. I have practiced welding steel square tubing together, and made a nice big cube. Would I be able to use that welder to weld chromoly? I am wanting to attempt the double reduction drivetrain on a single speed road bike. Would the welds from that welder hold up to the stress? I was going to get a bottom bracket from any bike I could find and weld it here:




And by bottom bracket, I mean just as pictured. Maybe less of the tubes though:



I am going to switch the front chainring to the left side of the bike, and have a freewheel on the left side of the crank (which is in the newly welded bottom bracket). On the right side of the crank will be a chainring the size of the front one, and it will be chained to the freewheel that is attached to the back wheel. What do you guys think of my plan?
