Shell fusing

I'm not quite at the 'shell level' yet but I've started thinking about it.
One question that I don't have the answer to is this:
How does one attach a fuse to a shell device that is itself ignited from the lift but burns slowly so that the shell bursts at its apogee - rather than straight away.
In 'little tests' that I've tried the fuse is always 'flashed' so much by the lift that the star either bursts in the mortar or just as it comes out.
I'm sure there's an easy way but can't think of it?

In use a hole is punched through from side to side about 3/8" from an end and a piece of black match is inserted all the way through. If the flight time is say 3 seconds then you measure off an inch and punch another hole and run some match through it. The black match provides a wonderful transfer of fire and spit as you might imagine.
As Big mentioned already the spoolette is used for cannister shells. On the smaller sizes a piece of the above fuse can be used but you won't find anything but spoolettes on larger shells. It's an anchor for your string. The manufactured variety is just not stout enough. If your new to it and can't find any Jap. time fuse I suggest you make a few can shells. :cool:
