Ah yes - thanks for loaning me that. A great help. The bottom race went on a real treat on the Trimble.
The Hei Hei is a bit more demanding - Smacking the headset cups off is a bit scary (didnt like the abuse I was dealing out with the hammer) - Ill probably get the shop to take these off. Maybe a workstand will be better atholding frame still like u said.
Do you really just belt them off? There must be a proper tool to pull them off?
