Measuring fork rake
I've messed around with various methods of measuring fork rake. I'm really liking this one. It seems accurate and repeatable. The pics don't show it but I tried it on two different forks, and I measured them with the rake going to my right (as shown) as well as to my left. All the measurements were very close.
The fork shown was designed to have 66mm of rake, but it's 67.5. The other fork was supposed to be 45, but it's 43.
I'm disappointed that the errors are in opposite directions, because it means that I can't blame the calibration of my jig... What can I blame?
Here I've positioned a pair of .250" parallels next to the magnetic block and I'm using two squares to align the side of the block with the center line of the 1" bar. Once the magnetic block is in the right position I'll turn the magnet on and lock the block down to the iron table.
