Removing Flanges from 3-Piece Campagnolo, FB Hubs

Ultra Detailed instructions and Photos Courtesy of Dave Hoag.



Big vise: 5-inches wide x 6-inche opening (pix 1 and 2).  Most vises come with knurled, hardened jaws, suitable for rough work.  For bike parts, use soft aluminum or copper jaws.  I made some aluminum jaws at Vo-Tec night school.  You can buy copper guards to place over the knurled jaws.  If you don’t have a vise, you might consider an arbor press.
Hole saws, slightly larger than the belled ends of the axle barrel (1 for front hub, 1 for rear)
Sockets, sized to just fit inside axle hole of flanges
Make wooden blocks for pressing out barrel from flanges (pix 3 through 6), one for front hub, one for rear.  Made from 2 x 4’s.  Drill hole just large enough to pass the barrel end.  Saw slot just wide enough to pass barrel.
For late model bombe flanges, cut ¾-inch thick blocks with hole wide enough to cushion the bombe from the flange (pic 8).

1.    To remove flanges, place wooden block with socket and hub in vise jaws, and press out the barrel (pic 7).  Socket will push out the axle as the vise is tightened.

2.    Press first flange on the barrel with vise (lubricate the surfaces with Vaseline first).  If flange is the older flat model, no cushion block is needed.  Use cushion blocks if flange is bombe. 

3.    Align second flange on barrel by hand, ensuring that the spoke holes are perfectly staggered from one flange to the other.  Press on second flange with vise, using cushion blocks if necessary.

4.    Check that spoke holes are staggered.

5.    Roll hub on a table.  If flanges do not roll straight, remove and reinstall.

1950s Colnago "La Freccia" (Arrow).

1950s  Colnago La Freccia, (ARROW), with Colnago FM Headset.  Down tube and seat tube have "1957 Campionato  Lombardia Dilettanti" decals.
*Bottom Bracket:  Italian 68 mm. 
*Dropouts are 1st Generation Campagnolo Gransport with 4 mm adjuster screws.  These dropouts were produced only  in about 1950-51.  This may have been because the oversized 4 mm shoulders were vulnerable to breakage and the Derailleur hanger had an impractical  4 o'clock position  stop, as illustrated in a set in the last foto.  This Colnago derailleur hanger  was removed, unfortunately.
In 1952, Campagnolo updated the  dropouts with smaller 4 mm shoulders and ultimately with a 7 o'clock derailleur hanger stop.
Top pics show complete bike with Universal Extra Brakes, Campagnolo GS Hubs, Simplex Derailleurs, Brooks B-17, Ambrosio Champion Bars Stem, Sheffield Sprint pedals and Magistroni cranks with  Simplex rings.
