I haven't been able to try the smoke I wanted to know if I set the can up right. I don't think there is any lining on the inside. It was a can of peas from Walmart if that helps any. Also my soldering iron had solder on the tip so I cut the tip off to where no solder was but I wanted some input from the experts if it is safe to use now.
YES my friend since you cut the Tip off it will be safe to use...If you want to check for a lining in the can, stick it on your stoves burner or fire up your grill and burn it out...You may find Drilling a hole the size of your Iron and placing it half the thickness of the widest part of the iron Handle, up from the bottom , will give a stable platform and a upright Can Smoke Generator that is easy to load...JJ
