Old dog, new tricks. PICTURES!

Well, I actually welded my crank to my sprocket successfully today.
On a non-motored bike which I broke a while back. I got my 110v out and used some 6013 rod and it went pretty well for me, the non-welder.

Thanks for listening,
Joe

I was affraid I was going to punch a hole in the sprocket by having the welder set to penetrate the crank.

After I quit screwing around and turned the welder up to 90a and slowed way down, I actually made a couple of short, crooked beads. More than enough material to hold considering what used to hold it together. It just looks like S*&t. I used two rods!

spectacular....

In photo 2 you can see the hole where the "pin" broke out of.

my tip, but not criticism, my first welds looked pretty splotchy too: more heat...linger on the crank long enuff for penetration, then slide down to the sprocket just long enough, then back up...it's tricky but not too.

Come on loco, I know you have something!

Never! Ever! Do you try to weld a chromed surface. Grind chrome off.
Good prep 'n fit is half the battle when learning to weld.
Practice on junk parts first.

Hate me for being honest if you must.

Well, I did remove some "chrome" around the junction of the sprocket and crank. I also removed some paint before I started.

Or are you refering to the electrode marks on the crank? Those were not intentional....

Anyhow, it holds.
