from what i understand, you have to use propane to do this. does
anyone have success using another way? i have problems with air
pockets in the center of my double. any suggestions? richard in
denver
Richard, I have a friend who also attended Harold O’Connor’s workshop
and liked the double. He uses a Hoke torch with natural gas and oxy
and has only achieved meltdowns, so I think propane is the best way to
go here. As to air bubbles in the middle, could you pull the flame
away and quickly burnish, it would have to be almost in the same
motion. I have done this with some success in fusing copper to fine
silver when I get an air bubble. The other way to fix it is to let the
double cool and then drill a tiny hole into the bubble, then reheat
and burnish the bubble out.
As to the mouth torch, I was hoping for a substitute for my acetyline
torch but the mouth torch just wasn’t the one that could do all I
wanted. I still use propane (a whale or shark torch, can’t remember
which). Donna in VA
