Last time I tried to saw a core it wiper the teeth right off a hack saw
blade. Maybe it was a bad blade? Tried another, then gave up.

Subject: [TowerTalk] Cutting a FT-240 type 33...in half ??
Ok, I have a requirement where an additional one or two x 2.4 inch OD,
type 33 cores needs to be added to an existing choke balun.
Since each end of the RG-393 silver plated + teflon coax is already silver
soldered to a 7-16 DIN connector at each end of the nema box,
I would rather not have to take the entire assy apart. Major pita. 393
coax has TWO silver plated braids, and in this case, each of the braids
has been carefully
separated at each end, and each braid is silver soldered to a lug, that
is bolted to the 7-16 din connector flange, via the SS 8-32 machine
screws.
IE: 2 of the 4 corners of each 7-16 din female coax connector gets a braid
attachment.
Can a 2.4 inch OD, 1.4 inch ID, type 33 toroid be cut in half, edges
sanded, then placed around the existing 4-5 turns of 393 coax, then
held together via glue, ty-raps, both, or some other method ??? I have
an excellent H-V bandsaw, made for cutting steel, hard steel, and AL.
IE: 80-120-200 ft per minute. It would slice through a toroid very
quickly. If what I propose is feasible, it would save me a lot of grief.
I already checked, and the big, type 43 snap on types will not fit, since
they only have a 1 inch ID.
Tnx...... Jim VE7RF
