That looks a lot neater, I've got to wait a day or so before I can do mine as the local hardware store only had metric countersink bit's so I've had to order one.
Enjoy your racing, hopefully a bit more now you haven't got the worry of screw heads standing proud, I hate that as I'm always afraid they're going to get ripped out. Fortunately I haven't got to run mine before it will be done.
