[TheForge] welding question

Tue Mar 26 00:26:01 2002

Hey, Dan...
I'd probably chamfer the stub 1/4",  run a 1/2" fillet all the way around on
the outside, then add a stiffener plate or two to the inside to keep the
tube from deforming (just in case) and if it's overkill, just chalk it up to
cheap insurance.
George.

PS-If you want to be extra careful, you can always run it with 11018!
