you can get different angled centers and I've seen them with a smaller diameter at the tip for clearance as well. so there are always options obviously since you came up with a solution with what was on hand.

collets are more about precision and less about rigid work holding. i never used them that often over the years and chucked 95% of the lathe work i've done. even if it was precision i then went to a 4 jaw chuck and indicated everything in. only time they were useful was for very light material removal on something that was a small production run. all the industrial cnc lathes at my work use hydraulic chucks which are much nicer for sure :)

sometimes with lathe work you have to work it sections at a time. i worked for a company that made industrial pumps and when you have a shaft 14 foot long a chuck and a center are not enough. often we used 3 steady rests to support the center of the shaft so you end up working around the steady rests as a result. so it pays off planning your work flow out before you start making chips.

so don't let it get you down when things don't always go as planned. it takes time to master the trade and even then you run into things that you end up fighting your way through.

Press and hold the Shift key after pressing the power button, choose the kernel with RT in the name at the grub menu (advanced something or another) and boot.
I will add the info for setting it as the default kernel.

Unless the bios has changed (and it may have) this PC worked OK for me.
You need to edit the bios to disable any of the C7 type wait states.
Too long ago for me to remember

I basically turn off everything in the bios. All the options on the CPU, the audio, etc.
