wow, that is a HUGE cup. I usually use an 8 or so with a gas lens.

Looks like you need to put more head into teh thick flange in order fo rthe bead to wet out more It is tough learning on thick material. I'd try to track down some .080-.100" thick stuff to practice on.

How do you like the Nomad table? I have one and it seems to work pretty well. Could be a little heavier material on the top though.
