Using the boring bar! It's worth noting that Titanium CAN catch fire in a lathe!! It's like magnesium. Thus, it's essential to keep things cool with the coolant and to clear the titanium hair. | Using the boring bar! It's worth noting that Titanium CAN catch fire in a lathe!! It's like magnesium.

In the process the oxide layer changed colours on the ring. Some yellow, some purple, pretty cool! One day, it'd be neat to try to see if it's possible to etch a certain colour with the laser cutter. (I imagine I'd run a coolant along the inside diameter of the ring to keep only the surface getting burned by the laser hot) | |||
I needed to flatten out the edges. Did that with varying grits of sandpaper. | I needed to flatten out the edges. Did that with varying grits of sandpaper. | ||
