Lenihan homemade charcoal heater

However, for anyone contemplating such a device, here follows a
description of the critter:

A -One length of copper pipe,at least 2" diameter and about a foot
or so long.
B -One copper cap to close off one end of pipe.
C-One pipe reducer fitting going from size of your pipe down to 1"
D-One 2" length of pipe one size BIGGER then item A.
E-One wire coat hanger.
F-One length of 1"pipe for smoke stack,length to suit your own set-
up.

With this collection of copper pipe,picked up at your local
hardware store,begin by cutting out a rectangular opening or hole
about 3 inches from one end of your 2" diameter length of pipe(item
A).This opening should be about 2 inches wide and one inch high.
Remember,item A is the heater body,it stands vertically,thus the
opening you are making should run horizontaly when the pipe is
upright.
Next,cut item D to length.That is,have it at least a quarter inch
wider then the opening you have already cut into item A.Slide this
collar(item D) onto the stove body(item A)until it covers the
opening you've cut.
Then,pierce this little collar with a dozen or so holes in a tight
grouping no bigger then the hole you cut in item A.
This then is what will give you some control over the "draft" in
your heater.
Next,just above the the hole cut-out in item A,drill a few holes no
bigger then the coat hanger wire,and through which you will run
short lengths of the coat hanger wire to form a"grill" or grid onto
which your little bits of charcoal will rest.
Is this making sense so far?
If you've made it this far with the construction, the rest should
become apparent with the pipe cap forming the lower end of the
heater,just bellow the openning and the reducer fitting serving as
the top of the heater.
This heater is loaded from above,say two to three bricquettes at a
time.
You then light the first or lowest bricquette leaving it to slowly
burn until it ignites the one above it etc....
Find a secure place to keep you heater when in operation as the
copper will get very hot.
Make certain that your chimney actually exits the boat!
Never leave this thing un-attended!!!
To enhance some of the heater effect, a large juice can can be used
as a heat diffuser.

Hope this all helps,for lack of a scan.
