Hi Dale:
Never have seen an article regarding capacitor knifing. What radio are you
working with? The only capacitor that is worth a try is one with a VFO that
tunes one range. Seems they always relegated knifing to an alchemist or
séance director locked away in some closet.
I've knifed a couple in the SR-2000 and SR-400, but, having been through the
process and the time involved, I'd replace it. The VFO in the SR-2000/400
have a slot at each 100kc point. You have to not only bend the segment but
change the angle of the bend to achieve good transition. Also, don’t do it
unless you have a good slotted tool or two with the appropriate bends. You
also need a good signal source with preferably 10kc spacing --- speeds the
process.
I have not seen evidence of knifing in the Hallicrafters multi band tuned LO
radios --- it's probably not possible.
Good luck Dale and let us know how it works out.
Kindest regards Jim K9AXN

Does anyone know of an article dealing with variable capacitor knifing?
Tnx,
