Boy you do nice welds!! what rod diameter are you useing? and what is the welder? Do you "cope" the ends on a milling machine?

Rex, Thanks. They better be good after all this time...Still improving though, and hopefully that never stops!
Rod diameter is tied directly to wall thickness on the tube. The thinner tube (4130) I'll use .045" or 1/16", and .095+ I use 1/16" or 3/32".
I run hot and try never to "disturb" the puddle. I use a Baleigh TN250 radial vise notcher and usually Morse or JMR hole saws. The Lowes Lennox ones work ok too.
Cheers
