"Wow. Are you sure that you just didn't make over 20 places for new splits to start"
No .And the reason is that all the splits that you see pre alma are where the staves have been joined togeather.This drum has very thin narrow staves so I drilled holes out of the way of the splits and drilled so much to bring each individual stave into the alma so there would be equal tension on each one.The Alma has stopped the flexing which was high due to the staves being so thin and hence the cracking.There is plenty of room for the skin to be pulled down with out touching the sides as yes the angle is fine (I checked it) Just sitting and waiting for the post now for the hardware...
