Yes Chy that is a good point.    Sometimes you do need to hold the piece your welding on in a vertical position so the puddle will not run off but stay and cool.

You are getting the hang of it.   Good job.

Good morning Roger, your words gave my way a good light to show the right direction to go, many thanks!

I do not remember if I ever showed this weld job that I did on a Husqvarna crankshaft that was broken on the end where the c-clip goes. 
----images---
When the welding was completed I duct taped the piston to the counter balance of the crankshaft and then turned it on my lathe to get the groove for the c-clip back to the correct width. 

Roger, it's also an amazingly good job! very impressive to see,
and appreciate it if you could give us some tips on this job please!

1stly, the filler material you used for this job:

This spring I tried one for McCulloch 740 crankshaft at its clutch end with oxy-acetylene blow pipe using soft steel filler rod, but failed.
Now thinking of rebuilding it with TIG, but your pics here may tell if you have used some special filler rod for this job....since it is known that crankshafts are fabricated with cast iron.

2ndly, the welding position of the shaft you did this job:

Should we better place the shaft on in vertical position when we work on the terminal? than placing this shaft on in horizontal.

Thanks in ahead.
