[TheForge] Welding 5160

Mon Aug 25 07:24:00 2003

Larry,  If it breaks - we'll probably forge out another one.

The option is still available to weld up with stainless however.  What are
you calling the SS blue rods?   308?,  309?, or the high strength alloy rods
for die repairs like the MG750?

My hopes are that the six hours it took to do the job from start to finish
is the last time we have to deal with it!   (hopeful grin with slight
question)

Ralph
