A tile saw with diamond blade and water flow on the cut such as tile
installers use is available in different styles inexpensively from
Harbor Freight.

Yes it is possible with a diamond saw in a surface grinder. However,
it is very messy and and the dust/slurry is very abrasive so the
grinder owner may say "no way". We machined a lot of ferrite many
years ago for recording heads and pretty quickly the grinders were
trashed.
You need very flat and smooth mating surfaces (see a big clamp on) as
this mating changes the magnetic properties of the core by inserting
an air gap. Obvious it can be made to work since #31 clamp ons are
very effective if kept tightly closed. A tungsten carbide blade will
cut ferrite in your bandsaw but I think the cut will be so rough as to
be useless. A diamond blade in a cut off saw may work if it last long
enough without water cooling.
I think you need a bigger NEMA enclosure as any of these techniques
will cost a lot more with probably poor results.

I have a one off application where I want to get 1-2 additional

onto coax, but dont want to take the existing CMC assy all apart.
The big clamp
on is aprx 1.5 inches long..and is too long for this application.
It’s a tight squeeze inside the
nema box, and coax is already silver soldered at both ends to both
connectors. Dual silver
braids have been separated at each end of the RG-393 coax, and
bonded to 7-16 Dins.
Can a type 31 2.4 inch OD core be cut clean in half....like in a
bandsaw ? I have a
vertical bandsaw with a metal cutting blade in... with 3 x speeds,
80-120-200 feet per
minute. The idea here was..IF a core can be cut in half, to place
the 2 x halves back around the
coax turns... and then either glue em back together..or perhaps use
a ty-rap around the circumference.
If cores cant be cut, I will have to disassemble the entire assy,
and start from scratch, which Id
rather not have to do, pita.
