The spokes "pull" the rim only in a direction parallel to their own axis. Heads in or heads out doesn't change the direction of that axis very much, if at all. It may change the distribution of forces at the hub flange, but flange failures are not very common, and not the cause of the OP's problem.

Nope. I've just seen a lot of potato chipped machine built (even some handbuilt) OEM wheels that were laced asymmetrically. Nobody does it that way any more so it not as common a problem. It can be a newbie mistake, however.

I have seen discussions of the problem in print but that was long ago and, like I said, it's not a common practice now.

The lacing may not be the issue either. I don't think it has much to do with how tight timin8r tensioned the spokes...I make very tight wheels myself...it may have more to do with not seating the spokes prior to tensioning the wheel and then flexing them when the wheel is tight. Once twisted, I'm not sure I'd use the spokes or the rim.

Sorry, timin8r. You may have learned a very expensive lesson.
