Rebuilding the smoke unit is not real hard. It is tedious because you are dealing with
very thin wire. I suggest you not rewind the wick yourself. Buy the prewound wick.
They are in the 4.00 to 5.00 range. I wound 2 wicks myself. One went up in a flash
of light and smoke in about 2 to 3 seconds. Not good. The other is still working but
not great smoke. I will not wind them myself again. I would say the more units you
rebuild the better they will work. Practice makes perfect. Watch the videos on rebuild
smoke units on the Portlines site. They have How To videos.
As stated, it is straightforward but tedious to rebuild the Gilbert smoke units. The good news is if you damage a wick or the nichrome wire you can just redo it. Rather than PortLines for this I would go to Ed Goldin, goldinhands.com. Take a look at his website.
