Any advice on the best way to slot hubs to accommodate
bladed spokes, please? How difficult would it be?

My dentist teammate used his dentist's drill on his CK.

Are there any hubs that are pre-slotted/certified?

slotting is not really necessary any more - most bladed
spokes these days are narrow enough to fit a
conventional hub.

if you /do/ have to slot the hub, some of the wheelbuilding
books show you how.

See if you can find someone with a factory slotted one that will trade. I have a HB-7700 new DURA ACE 32 hole factory slotted.
I would make a straight accross trade. I know that most who are doing aero spoking want fewer than 32 spokes.
If you can't trade, make sure the slots are only in the direction of the hub center.
There are some spokes that are aero that will fit through spoke holes without slotting. Sapim is one manufaturer that comes to mind.

Even at my "skill" level and tools, I wouldn't do it
especially with me guessing that you will be using "low"
spoke count. How about using some semi-bladed spokes that
will fit into those holes without mod... or just buy hubs
with slots. Shimano/Dura Ace makes them, not sure about
Campagnolo.

Both Ritchey and American Classic have good hubs
available slotted.

Thing is, I already have the hub (American Classic
Ultralight) and the spokes (DT 14g blades. I want to build a
24-spoke rear wheel and couldn't find a source of semi-
bladed spokes that were short enough (~260mm) and not
extortionately expensive. I looked at Sapim X-rays ($2.50-
$3.00 per spoke!) and said 'No thanks". It seems the spoke
holes in the hub are wider than in most hubs, so not much
slotting is required. It will probably be sufficient to cut
a slot just to where the countersinking around each hole
finishes - I'm just a little nervous about ruining a very
expensive hub.

I've successfully used the BPP hub slotting tool, apparently
no longer made. See

There's a tool to broach the opening into a slot, sold by DT
I believe.

Here, we use primarily Hoshi aero blades when we have to go
aero and those ( 1.0 x 2.65mm) have a round 15g J-bend so I
have never done that job myself.

Not diffucult but time consuming. I have a wee tool, with a
pin that rests in the hole, and a hole above it for the
drill bit, andf a handle. Hold the 'guide', drill the
holes...takes forever, ya go thru a few bits(broken) but it
isn't diffuclt.

There are many small diameter oval spokes these days but
they start life as pretty thin spokes. If you want the
strength, ya still need to start with a 14g spoke,
flattened, which requires hub slots.
