Quite good!

In the UK, the cheapest head set removal tool I could get was about £20. It's virtually useless as the tip of the splines are quite thin and are prone to slippage, whereas this tool seems more robust and has increased surface area to get those pesky head sets out!

good idea and good work . this should also work for certain old bottom brackets too.

1: What is it again? 2: It's just like the same picture over and over. If you can take pictures after can't you in between?

1: It's a headset cup removal tool, again. 2: Yeah, I know. More pictures would be better. The how-to was an afterthought, I can't exactly take picture back in time. Perhaps you'd like to build the tool and document it's construction more rigorously?

I still don't get what a headset cup removal tool is.

It's to remove the cups (2 of them) out of a bike headset. The cups support the fork and bearings allowing you to turn safely ;) They are also pressed in, so they can also be pressed/forced out.
