All the old school Kleins had a pressed in
bottom bracket. Some people used a hammer to get them in and out
but there was an official Klein tool that was used and I figured, might
as well use a tool designed for the job. As such, I fabricated my own
Soon enough I'll have a photo guide how to use the tool but that is for
Everything was created from raw metal stock
except for the threaded rod (we could have made this but it would have
been a lot of threading or just go the hardware store and buy the rod
for $4) and the bearing (see below). I asked where we could buy
the nuts and they said, "We'll make them." And that's what
The front three pieces are part of a radial
I looked into buying a radial thrust bearing but
they're pretty expensive. The basic purpose of it to allow you to
push on the bottom bracket but not twist it. Turning the handle
of the press would cause twisting motions on the pieces. So the
bearing will allow the rod to rotate but not the BB parts.
So the larger piece pushes against the bottom bracket (the bearing fits
inside it) and the smaller part is against the rotating threaded rod
and pushes aginst the inner race of the bearing (which rotates).
The bearing is an old bearing from a Klein BB that I had sitting around.
These two parts are used to remove the bearings
from the BB spindle. These aren't a part of the official tool but
something useful to have around. These are used in conjuction
with the headset press and you'll have pictures when the guide to using
the press is made.
One thing interesting about these parts is that these were the first
parts that I made on my own where I saw problem and create a
solution. All the other parts up until this time were
copied. These aren't intricate parts but it's part of the learing
process of "Aha...I know what to do."
Now I do that all the time but back then, it was enough trying to
remember to remove the key from the lathe before starting it up.
A key is similar to the tool that tighten the chuck on a drill.
It's a well known thing among machinists:
ALWAYS KNOW WHERE THE KEY IS BEFORE TURNING IT ON AND YES I'M SHOUTING!
If the key is in the chuck when you turn it on, it can throw the key at you and embed it in your skull. Very bad!
Below is a standard headset press that was adapted from the Klein BB
tool. It's not complicated, just made two disks and voila...a
headset press for non-Klein bikes.
