That is two completely different things the way I read it. Can you clarify?
I have found that if you were to cool the WELD with a wet rag you shrink the metal, the molecules gather when the metal is quinched. This is how you shrink metal when you WANT to shrink metal, you heat it to get the molecules "dancing" around then cool it bringing them closer together shrinking it.
My tack's are around 1/4'' to 3/8 because I use a hot tack... Now I proved it with pictures of ME doing it... NOT SOMETHING SOMEONE SAID, NOT SOMETHING I READ,,, BUT SOMETHING I DID.... more then once..It work's well.. You can try to pick this a part all you want.... These pictures don't lie..
I just finished a chop top the same way... I just finished my son's bed,, The same way... What more can I say...
I will say this much... If someone is afraid to step out the box,,,
YOU WILL NEVER KNOW WHAT IT'S LIKE ON THE OUT SIDE...
Don't be afraid to mess up... THAT'S HOW YOU LEARN..
Oh.. And if you really would like to know... I have done it the way Al posted... Many times...
