Old Campagnolo track hub

Bob-<< I noticed that each spoke hole is chamfered (rounded or countersunk) on one side only

These countersunk holes are for the spoke shaft, not the spoke head. For a better spoke line outta
the hub for the spoke. These were common until about 1989 or so with higher end Campagnolo and even
Maavic hubs.

After I took the wheel apart and inspected the hub, I noticed that each spoke hole is chamfered
(rounded or countersunk) on one side only (alternating sides, of course). I have built a lot of
wheels, and all the hubs with aluminum flanges that I have encountered have spoke holes that

chamfered on both sides.

My question is: On which side does the spoke head go?

My first thought was that the head goes in the chamfered side, in order to provide a place for the
spoke head to sit in.

But on the other hand, it would make sense that the chamfer is intended to support the
spoke elbow.

Which is it?

It is chamfered to support more of the spoke's curve. The head goes on the "plain" side.

I've never seen a Campy 3-piece hub. Are you sure this is actually a Campy item. If so, is it
just a lot older than the other parts I've seen. My experience goes back to the early 60s. How
old is this hub?

Thanks. The wheel is now built with the head on the plain side and the chamfer supporting the
spoke's curve.

I was wondering that, too. I have a '65 (or maybe older) set of Campy track hubs, and they are
one-piece aluminum. I also have a quite old FB front hub that is three-piece with a steel barrel.

Can you (OP) post a picture of this hub?

They were produced during the 1950s, superseded in about 1958 by the first one-piece aluminium hubs.
My impression is that the small-flange model was more common than the large-flange.

I don't know any more about the hub than I've already told you. The bike from was maybe 10-15 years
old in 1972, which would have made it new in about 1952-1957. (Andrew Muzi reports that Campy
started making one-piece aluminum shells in 1958.)

I replaced the axle, cones and locknuts when I bought a new Schwinn Paramount track frame in about
1978. The old axle was spaced for 95 mm (that was my measurement, but it could be 96 mm, according
to Sheldon's site), whereas the new frame was spaced at the current standard of 100 mm. The old
axle's diameter was also smaller than the 9 mm that the new frame expected. I still have the old
axle with the original axle nuts. I sold the Brooks frame at about the same time.

Unfortunately, the hub's steel barrel is rusted in several spots, due to the salt air here near
the ocean.

The front hub has 32 spokes and the rear 40, which I understand was common practice in Great Britain
at the time. I had no trouble with it before it started breaking spokes at the nipple, despite
throwing the bike around during sprints over the years. I built it cross 3 with what appear to be
15-16 gauge Stella spokes (no longer in business, as I understand). I weighed about 185 lbs in the
day and 210 lbs now.

For the new build, I used 14-15 gauge Wheelsmith spokes. The hub is apparently designed for smaller
spokes as I had to thread the new spokes through the holes.

Right the second time. The countersink is NOT for the spoke head to sit in, but to reduce stress
risers on the bend.
