Another thing that might help you, in using a 1x42, x-weight belts are available. They have a stiffer backing. It can help when you reach the tip with the belt wanting to curl and grind your tip off.

HD has more technique on the tip since he learned to do it without them. I have always used them, then discovered how much harder it was without after the fact.

Still, even with the x-weights, I use the same technique as HD.
