DIY headset press tool for $11.52
have a need to install bearing race cups into the headset, This
operation requires even force applied to the headset cups, which must
be installed evenly into the headset tube to prevent damage to the cup
and the frame. Being a cheapskate who would rather spend money on
components than tools, I decided to take a stab at building my own
tool rather than shelling out $50-$100 for the appropriate tool from
Park. Dan from MonkeyLetric (maker of those awesome POV Spoke devices for
displaying video on your spoke) posted a great design on Instructables
(http://www.instructables.com/id/How-to-make-a-bike-headset-press-%26-install-....
The idea was pretty sound: buy some all-thread, washers, nuts, and pvc
pipe to squeeze the headsets together. Not wanting to buy a hacksaw
and not trusting my ability to cut a piece of PVC flat and smoothly I
went with a copper pipe fitting which fits perfectly into the cups. I
also put a rubber washer in-between the fitting and the cup to prevent
the race from getting scratched or pitted. This setup is very simple and straight forward but with one caveat: it
is very difficult to get the cups in straight. You will not get them
in straight perfectly the first time. After some fiddling I discovered
that the easiest thing to do was screw the fitting in until there was
no play between the washers then use a rubber mallet to gently knock
the copper fitting around to level it and it should stay pretty
straight. - 1 copper pipe fitting $6.59
- 1 bar of 3/8" all-thread: $3.00
- 5 nuts: $0.50
- 4 steel washers: $0.40
- 1 rubber washer $0.10
Sub-total: $10.59
+ 8.75% sales tax: $0.92
Total: $11.51 (ish) Not bad compared to the $50 Park HHP-3 which is basically the same
thing (nuts with handles spinning a piece of allthread) or the $110
HHP-2 which is awesome, but would eat into my component budget.
