How to modify a 'D' engine to a 'C'

Too windy to launch those rockets?  I have a black brant II which
really screams with a 'D'.  Unfortunately I've come too close to
having it blow away on those windy days.  I figured out an easy and
cheap method of modifying those 'D' rockets to a 'C' without a hassle.

Take an old used 'D' case, and make the hole in the clay nozzle
bigger.  Either use a drill bit or something, I just used my pocket
knife.  Then slide a 'C' engine into it, so that the ejection charge
of the C was pointing to the opened clay nozzle of the 'D'.  You might
want to wrap some tape around the 'C' to get a tight fit.  Something
like this:

                              _________opened clay nozzle of the 'D'
                              | _______ejection charge of the 'C'
                              V |
                        +----   | ----+
                        |  |    V  |  |
                        |  |_______|  |
                        |  |       |  |
                        |  |       |  |<---- used D engine case
                        |  |       |  |
                        |  |       |<------ New C engine
                        |  |       |  |
                        |  |       |  |
                        |  |       |  |
                        |  |       |  |
                        |  |       |  |
                        |  |       |  |
                        |_ |       | _|
                           |       |  
                           |__\ /__|
                                ^
                                |________C engine nozzle

I wrapped some masking tape around where the 'C' sticks out of the
bottom of the 'D' so the ejection charge can't blow the 'C' out of the
'D'.  Now you can use 'C' engines in a 'D' rocket.  It works GREAT,
and the converter is free - after you have burned up a few 'D's.  :-)
