Interesting how hey talk about crosswind, something I have forgotten to chat about. Say there is a crosswind going from off side to leg side, and a right...
I'm confused, what are you trying to say here? That drift is not due to the magnus effect and due to the seam presentation effecting the laminar flow over the ball?
edit: then why do those toy balls for babies that do not have seams, drift and not swing. I have bowled with a light soft ball...
Found this nice University of Sydney science paper that also has some nice pictures about fluid physics. I haven't read through it yet but it's intruiged me.

edit: looks like it's the same bloke from the University of...
'Laminar flow' ? How is that in relation to the lift and drag forces of the magnus effect? The hard thing to get a clear picture in our minds is that the ball doesn't travel in a straight line all of the time when bowling, but you can simplify things but thinking of the 1st 3/4 of the ball path...
I just think of it as swerve as the ball falls down, you don't want exactly the seam exactly upright since the ball path as it's falling down towards the batsman isn't exactly a perpendicular lineto the ground when viewing from side on it still looks rather flat, hence why I think having quite a...
Just referencing my old post, I recently found a clip of a Shane Warne dismissal that shows how I imagined myself bowling back then, go 2:16 in & watch exactly how the ball is released, not only does he spin it up but he goes right over the ball & push out the side, creating that dipping path...
Perhaps it's not so much the angle of the seam(towards slips) if you would look at the ball from above the wicket, maybe it's the slight slanting of the seam towards the batsman that helps produce the drift. I'm not so sure that when I'm bowling my overspun leg breaks that I am getting a a...
Today I tried a few square seam leggies with a rounder arm action and got about a foot & a half of in-drift, it wasn't late drift but at least I got some drift for once, as my overspun leg breaks aren't getting any drift, just dip. As I released the ball square seam I pulled back on it with the...
Hmm, maybe work on getting left hip more up and over as you've started pivoting instead of round one another? It should help you finish a little more with the follow through a little more to the right and not cut your pivoting short, helping you stay a little longer on the pivot/front foot so...
The difference between Macgill and Smith bowling action was like light & day. The way Macgill grooves the ball's flight path before it gets released out of the hand while having a round arm was the biggest difference. Steven Smiths arm is too high and might even have been past the perpendicular...
