You may also cut the wire, but do not forget to reserve a few centimetres at both sides. The wire-
endings have to be directed into one direction and are not allowed to pass through the hole in the 
coil-carrier (see fig. 5).  

Fig. 5: coil-carrier - completed

Having completed the coil-carrier, you can fix the structure into the core with some 

instant glue

The wire's endings are to leave the core at the closed core-side through a slit (see fig. 6).

Fig. 6: Coil - fixed in the core

At   this   stage   you   have   to   remove   the   isolation   at   the   wire-endings,   starting   at   one   or   two 
millimetres from the core towards the outside. The optimal tool to remove isolation is a soldering 
tool with some fresh solder at the soldering tip. Apply the heated top for some time until the 
isolation has been removed and a thin layer of soldering tin is covering the wire. Warning: the 
generated smoke may cause damage to your health and should not be inhaled!
At last you put some instant glue to the backside of the coil and fix the 10nF-capacitor (imprinted 
text:   103)  in   a   suitable   position   to   point   the   wiring  connections   towards  the   slit   for  the   coil- 
windings. Fig. 7 demonstrates a location for the capacitor besides the carrier's hole – just in case we 
may need the hole for some other purpose. The published design however does not really require 
this exact position. 
Now cut the capacitor's wiring connections to approx. 5 mm, wind the tinned copper wire-endings 
around   these   wiring   connections   (maybe   using   a   pair   of   tweezers)   and   fix   the   connection   by 
soldering.
