The very same thing would have been accomplished if you did not cut any material off of the head tube and slid the upper and lower crowns up the stanchions an equal amount. Or if you went from a 6" fork to an 8" fork on the same frame. You would have slackened the head tube angle.
Exactly my point.
I'm not saying that I want to make head angles any different by cutting, just that there is an effect.
Raising the lower crown or making the axle to crown distance greater raises the front of the frame and gives a more slack head angle.
As would the starting point that I was using.
The top of the head tube lined up with the bottom of the upper crown, and then cutting the top off and then re-alligning the top after the cut will make it more slack.
The triple clamps on the fork tubes get raised and then tightened to hold it in this position, or in this case, the smaller area to fit the head tube is what holds the position, and the fixed lower clamp did not move.
Cutting the bottom off did not move the frame because I started with the top already lined up and just cut the bottom to fit in my scenerio.
just as when starting at the lower refference point (bottom crown), cutting the top off also did not move the frame or head angle.
It's stil X and we have actually been going off of the same theory, but from opposite ends.
