what I would do to fit one of those tensors,
look on the bottom of the cylinder for the little holes, this will give you the proper spacing and size of holes,
you could use a needle file to cut the space between the holes, constantly checking the spacing,
do not try to cut the full depth of the comb, do not try to cut the full with of the interstices on the comb,
Just postion a small cut in the place where the interstice is to be cut, and do this for all the interstices until you have the beginnings of the cuts positioned, then you can go more in detail and widen the cuts, leaving the tine in its full width dimension.
this allows you to start and work on spacing and tine width in finer focus,
you are not going to successfully chop out a comb with files, by going full depth on the first tine and interstice. by the time you have six of them cut, you will be badly off spacing,
but by starting small on all the cuts, you can lay it out so that when you work it into shape you widen either the right or left side of the cut so that the tine will be full width and the cut, is worked out wider to open its space,
there will be a lot of minor tweaks that will bring all 6 tines into position. you will look fit and then make a cut then look and fit again, this way you shift the emphasis of the cut to the left or right side of each cut to make it fit as you go.
the tines are not deep so any mistakes made on the first cuts can be removed by cutting the whole edge of the metal comb to flat with a wide flat file.
Work slow, keep looking and checking spacing and tine width against the holes on the bottom of the cylinder.
Wake up and smell the Kafka!!!
If any one has any ideas on how i could remove the core with out damage ? Could you please help me out Thanks! 
ill keep trying
