for SUNPPAA why turning away from the chuck is better.
 
01:20
304 stainless steel. my favourite machine channel asked why i always turn away from the chuck. this forging is 2000mm long and turning towards the chuck would not be possible without using a steady rest which would easy add 2 hours extra time to turn. 7mm cut to remove the scale both ways.

Awkward holding Titanium forging. Bored to 186mm.

Titanium forged ingot. I had to bore without any machining to any outside diameter. If this was a heavy steel it would not be safe to hold like this.

Heavy roughing and finishing cuts 304 stainless steel
 
10:08
This steel cuts very easy but is difficult to get it to chip. It sticks to itself as you cut it and the best way I find to get a good finish is a .010" or .25mm finish cut.
