So, the cut off wheels did the job? Good to know. I've found Dremel cut off wheels to be handy for many tasks, like
this.
Just keep in mind there are (2) different kinds of cutoff whiles that
fit the dremel tools.
The solid dark brown ones that often come with the tools, that have no
surface texture..and ones that look like miniturized fiberglass wheels
with an "embossed" grid..which is actually fiberglass that holds it
together.
The first ones..are fragile like glass. The second kind is quite good.
Good ones:

I like the EZ-Lock kind better. They swap faster and they
are cheaper than the plain-arbor variety:

Nonsense. These cut through the sides of the 3/4-16 nut
quite quickly and easily. They *do* require dexterity
and skill to use properly. (I mentioned that one shattered
before I could do anything with it.)
I found that by storing five wheels mounted on arbors, I
could make a lot of progress quickly. Instead of laboriously
swapping discs during the job, I swapped the arbor/wheel
assembly instead. Very quick and efficient. I use
'less valuable' time for mounting a new set of discs on
arbors.
I could not make much progress with the thick reinforced
wheels in this very demanding application.
The reinforced wheels just bounced on the top of the cut.
'Strange, because I've used the fiberglass wheels in
cutting less-demanding workpieces like lathe bits
and they work just fine doing that.
They both have their place and it depends on your skill at doing fine work.
I concur! If I had nothing but the reinforced wheels,
I would have been working on that project *much* longer.
OTOH I was thankful to be working outside because the
fog of abrasive released by the standard cut-off discs
is obnoxious in a closed room.
