It was way back in July that I turned the blanks for various length steering stems. The various lengths allow me to adjust the amount of dive that happens under braking.
Here's where we left these parts:
Now these parts will be brought to the 4 axis mill and have the pivot holes and clamping faces machined. then i'll switch to another setup and trim and chamfer the ends.
The first step is holding the parts in a 3J collet on one end and with a dead center in the other to ensure the part axis is coincident with the mill 4th axis. That means that the zeroth step is to align the dead center to the 4th axis. I machined a round adapter that helps greatly in this process:
That's all for now.
