Okay so I am sure someone is going to spank me on asking this because it was answered before somewhere buried in the posts. But I can't find the exact answer to my question. So here it is:
I plan on making cake boards with 500 gram cakes. I want them packed close so I can fit as many cakes on a pallet as possible. I want 1 to go off right after the other. So with some cakes running 35 sec or even 30 sec. I am unsure of what type of fuse to use. I have 21 sec and 10 sec fuse from bigs and I think they will both be too fast. If I tape the cakes together and I have the fuse running along side each cake hitting each fuse of each cake as it goes I think that in some instances I will have less than 1 foot of fuse between cakes depending on the cake diameter of course. So for example if I had even 1 foot or less between each fuse on 2 particular cakes I wanted to chain together, the cakes 21 sec fuse and 10 sec fuse would screw me!! Does that make sense? What I need is something at say 50 sec so I have some options when I have smaller cakes blocked together. If I donít do this I will have to take my 21 sec fuse and pull it away from the cake so it last for a 35 sec before it hits the next cake. Am I correct on this or not? Is there any fuse I can get that runs 50 sec or around there that is not so thick it will be a problem linking it to the cake fuse which may be a smaller diameter?
