What I first did was measure the depth of were I wanted the spinner. Then I take a strip of masking tape and tape the side of the fuse and bring the tape to the block. There I put a pen mark where I want the hole to be drilled. pull back the tape just past where the cowl sits. position the cowl where I want it. Bring back that strip in the staight line and drill through the cowl and the block. Do that on all five blocks. I think I added the top one. Then I get the small nylon screws and tap the block for the size you buy and that is it. The cowling will never come loose with those nylon screws. Hope you can understand what I described. as it is an old modelers way of doing it. It is very accurate.
