All of his videos I've watched are first rate.

awesome!!!

I guess small diameter drill rod/silver steel could also be used.

I saw someone do this using cheap (dollar store grade) needle files as a poor man's hard facing rod on some sort of tool, may have been a small hammer of some sort. Sam idea and reportedly worked well enough for the application at hand. Lots of options if you use your imagination I guess.

Concrete nails?

I have been a Boilermaker for 40 years and have been looking fore something as a filler for hard-facing with Tig. I will give it a go,
Thanks very much for the informed Video. I just had never thought of using a drill.

I wish i could weld up some camshafts and have reground for roller lifters....among other things.

marksbug - Camshafts are usually made out of one of the grades of Cast iron, not something easily welded.

Allen Millyards video shows how https://www.youtube.com/watch?v=7myf...gmNR&index=3he welds camshafts for his specials.

That was interesting.
Those camshafts were made from steel, I wonder how much hardness has been lost from heat form welding?
