this is an interesting way to remove an old headset.
I just sawed some lines into a copper pipe, bent the ends out, and slip it down to grab the edges of the old headset cup, then hit the end with a hammer. Its a homemade version of a commonly sold tool.
This washer and punch setup is very interesting though.
And for the crown race, I just use a chisel and hammer with a handful of hits all around the race to loosen it. Maybe thats always worked thru the luck of not having difficult races to remove?
Anyways, cool process. Its neat to see alternative ways to how I do things. A different perspective helps with knowledge and problem solving.
