couldn't you just drill out a larger hole in one of your small
The short answer is "yes, you can." However, the owner's manual that
came with mine specifically warns against doing that, or enlarging,
swaging, etc., their torch tips. They also warn against poking wires
or anything else in them.
I'll assume the main reason is because, here in the US, litigation
abounds. I recently read an article about how sad it is that
manufacturers here must use the silliest disclaimers to prevent
lawsuits by consumers who either modify their product or misuse it
in some inane way.
Probably the most important reason to not drill out the two smallest
tips that are supplied with the kit (the #3 and #4 tips) is because
they have sapphires in them and are designed to be used ONLY with
acetylene. Use the #5, #6 and #7 tips for propane and natural gas.
