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.
