Drilling the tailstock ram for the Lorch. This needs to be very very concentric so we need to go quite carefully. As I slightly muntered the edit, the order of operations is as follows: - True up stock in the chuck, and support it perfectly centred with a steady - Drill undersize to a depth of about 3x the diameter of the target drill size - Bore out the drilled hole to exactly the final drill diameter - Final drill to depth - (ream) I couldn't work out how to put a meme in using shotcut, so I just left that bit blank. It works, I think.
