How to make a bike headset press & install a headset

Step 4 Install second headset cup

For the second cup, you will need to use a different plastic spacer setup in order to be able to get the spacers out after you put the cup in.

It would be nice to get an idea of approximate pip needed..frankly all I see is basically what look to be like a about a foot of 2" pvc. Also what is the round metal showing on this pick?? I though you would have the pvc spacer on each side of the cups so what is the metal?

NO NO NO!!! Never pres against the inner diameter of the cups as this can not onoly warp them but also potentially damage the case-hardening of the cups themselves! ONLY press on the outer ring of the cups such as using a bolt-and-washer design. Ideally in this photo the lower piece of pipe should not even be in this pic, it would have been better to leave the wood to handle the pressure DO NOT follow the above example or you may damage your lower, and mos5 critical, headset cup. Press flat against it's outer edges only...

The Park Tool version used in bike shops everywhere presses on the inner cups.

Yes, but that is a tool MADE for the job. When using something other than that, it is best to press on the outer lip of the race.
