get a thin metal tube inner diameter 2,3,4mm .4 inches long (for tobbaco) this lenght can be adjusted depending on what your use is.

that then goes into a larger container .this larger container could
have a lid that srews on .you could then push the metal tube through
the centre of lid.so it looks like a straw coming out of a
macdonalds coke.

then cut the container in half and mastic a new top on the bottom
half of container this is where you can suck this herb air.you need
to mastic new bottom if the bottom is to big to suck on.(remmeber you
are not sucking air through the tube end)

then you can unscrew the lid to get at the tube end that sticks threw
lid.you can then put in your herb into the tube. how to keep herb in
tube is not been worked out but stuff brillo wire is being

considered.i just stuffed tobbaco with a pin into tube.and it stayed.
the idea above is that you can now heat the tube from the side(we are not heating the side next to herb only at the very end) and
not have the flame go down the hole of the tube .you just get the
tube red hot at the end and middle and thats what makes the air super hot.hopefully the herb is not vaporizing because the tube is hot next to it,but is the air passing threw a it!
so the air itself is hot and this is what is vaping the herb

i have tried it with tobbaco and had to use a plumbers gas touch to
heat tube ,but it worked,the tobbaco rolled down with a ease that
was not known before.no gagging on the lungs.
weather not allowing the flame to suck into the end of the tube is a
good idea or not i thought i would try it out.i have only just
started last night.

i wonder weather stuff a little ceramic fiber down tube then drop alkaloid down onto ceramic fiber then but a little fiber ontop.

2.
get a 40 or 50w halogen blub a dimmer switch (i getting 12v dimmer
because i only have 12v possible).
a 240v 40w halogen bulb will burn tobbaco if you push the tobbaco
against the bulb.
so my idea will be to house the halogen bulb in a metal container
small ,with a small hole to let vapor escape. this will be housed
somehow in a bigger container which will then be sucked up into
lungs.
i havent tried this or built it.my idea is because tobbaco burns when
you touch it to bulb then any alkaloid below this vapor point should
work with tweaking of the system.
the dimmer switch should beable to control temperture ,so allowing
other drugs to be vaporised.
also if a heating filament wire was used one might be able to coil
this round a thinnble sized container and heat like that.this is
something i might try but i dont no jack about filament wires or how

they work.
