To be perfectly honest with you I never use them. I back drill all my new holes from the inside. Picking up holes on a new sheet using the old is a good way, but on flat sheets only. On replacing the channel, I drilled pilot (#40) holes first in order to center them in the channel, then installed the new skin and back drilled them through the channel from the inside. After all is drilled then come back and step up the holes to final size from the outside. No matter how many clecos you have you will always be 25 short. To back drill the channel holes you will need an off set or "dog bone" drill attachment Brown Tool - Cart: 1121812
