Very good, glad it went better. That the softer lead worked, and that fluxing the harder lead didn't solve the barb fill-out problem is a likely indicator that the barb isn't vented adequately. If you wish to use hard lead in that mold, you might try some of your venting tricks on that barb. That
and fluxing may just do the trick.
I have thought about trying one of those long push-button bar-b-que lighters, as that seems like perhaps the best thing to light the volatile wax smoke-- or to re-light it quuickly if the flame goes out. If anyone gives that a try, let us know how it worked.
Good luck!
