It's a constructeur rack, and you are the constructeur.

Effort == results A rack like that is NOT "plug and play." Period.
I have one on my Johnny Coast-built VO Randonneur

It took several hours to install, and I learned a lot about working with
stainless steel I never knew. I had no idea ordinary hacksaws and
drills would make no impression on the stainless steel other than to
polish it, and it literally took over an hour to cut the tang and
another hour to drill it. I also had to bend, and then re-bend, the
tang.
It came at a great time: it was Monday, and I'd retired the Friday
previous. It did a lot to keep my mind off things. Totally involving,
and at the time, a great blessing. Pain in the rear? Not really; just
not even slightly "plug and play." As I said earlier, it's a
constructeur rack and you get to be the constructeur.
As for "it's made for this frame so it ought to fit," a friend of mine
has a small size production VO Randonneur. She had the rack installed
at her LBS, and it didn't fit. Took it to VO, and they had at it; had
to cut the tang off entirely to get it to fit.
You have to remember, this is not a custom rack. It's a production rack
and as such a compromise that can be made to fit most of these frames
really well, once you get done working it over. It doesn't fit all of
them equally well, and in the case of the really small sizes, the tang
doesn't fit at all.
Still, the VO Randonneur front rack is $80, $55 on sale right now. A
custom rack like the one on my MAP is $375. That rack was built to fit
my frame, and it fits as well as the paint on the frame. The builder
did all the work, and it's perfect in every way.

No hassle of any kind, but 5 - 7 times the price and it's available only
with the frame.
I'll bet the Rack Lady could build an equally perfect front handlebar
rack for your frame; she did a spectacular job with the porteur rack for
my P/R shopper. But, it took several months and I had to send her the
fork, and the cost will be comparable to the MAP custom rack.
If you have a bike that will fit the Nitto rack, it's an obvious choice.
The Gilles Berthoud rack is another fine choice; I had one of those on
my Saluki for several years. It's heavier than a custom rack, but at
$150 it's about half the cost (and about twice the price of the VO
rack).

> didn't solve my problem with the Al fenders moving from side to side and rubbing on the tire during climbs
I can't think of any mechanism that would cause the rear fender to move when climbing, unless you're getting a huge amount of frame flex. I have seen situations where the front fender hits the tire due to fork flex, usually right at the front end of the fender.
My hunch is that this is occurring when you climb standing.
If it's the rear wheel, I think what was happening is that your fender is too close to the tire (there should be 8-10 mm clearance from the tire at its closest point) and that as the wheel flexes while you climb the tire rubs. The point of contact is probably on the left (non-drive side) near the brake bridge. Rear wheels flex is a slight potato chip shape as we climb standing; we rock the bike which introduces side loads and the pedaling torque on the drive side spoke tightens the trailing spoke and slackens the leading spoke, causing the rim to move. This can cause the rim to hit the brake pad, usually the one on the left, and a fender if the fender is too close. This is less likely to happen with a tight wheel (but a tight wheel is more likely to crack the rim around the spoke holes, since rim design has been drastically dumbed down in the past 15 years; a tight rear wheel may make a bike less likely to shimmy, as well).
Back in my racing days on climbs you'd hear this "vrrrt vrrrt vrrrt" noise as the peloton climbed from rims hitting brake pads due to wheel flex. The became more prevalent after the introduction of dual pivot brakes which need to have the pads set close to the rim. Pro cyclists will sometimes reach back and release the rear brake when doing long climbs to prevent this. Campy came out with a dial pivot front/single pivot rear brake setup a few years back which I think was intended to prevent this problem.
I'll bet you're right. It can happen in front, too, perhaps from fork
flex.

The Nitto M-12 front rack is a 5-10min to instal/remove on my Ebisu All Purpose,
so it is possible to engineer these things to fit easily.
The Nitto M12 (& its sister M13) don't have provisions for adjustment
but are still easy to install -- cantilever brakes only however.

For the best performance and long life metal fenders *need* support at
the front edge. It's much more secure & robust that way. If you
can't attach the fender to a front rack then an additional stay can be
used. There's a reason the French did it that way. Not saying you
can't get away with no support forward of the fork crown, but the
fender isn't fully supported without it.
FWIW I bought a VO "constructeur" front rack a couple years ago and
gave up on it before I even started to try to fit it to a bike.
Anyone who goes through the work to fit one of those up definitely has
my respect. I'm Nitto M-12s on all my front-racked bikes...

Yep, I get some front fender rub on one of my bikes when climbing standing. There's just not enough clearance under the fork and the front brake, so one edge of the fender is about 2 mm from the tire. The fork will flex enough when I climb or ride out of the saddle to rub just a bit. At least I am assuming it is fork flex.
Huh. Interesting. With many aluminum fenders the attachment under the fork is a bolt through a hole rather than a tab as on a plastic fender. I suppose that can let the fender rotate with the bolt as the axis. IIRC there's supposed to be a rubber washer between the fender and the fork crown, presumably to stop rattles and to impede the fender from moving.

Ah. I am too lazy to run down to the parts box and check but my recollection of that the crown attachment (for Japanese alloy fenders) is 1" consistent with the diameter of the head tube. I wonder if 1" ring spacers such as for a 1" threadless stem would work better.
I think they were quite clear. Quoting from the instructions:

Bending and drilling are very clearly marked, and a comment is included about stainless steel. Nowhere do I see anything that says "bolt-on solution," so if anyone suggested it, it would have been you, and not Velo Orange. How much more explicit would you have liked them to be? I strongly suspect you didn't read the instructions, either before purchase or after, and if that's the case it's entirely your fault.
