This technique is fast and makes a perfect fit without being really precise.
FIRST
Glue thin ply on the last bulkhead and make block for the nose .
SECOND
Mark bulkhead and cut excess.
THIRD
Secure block to fuse and drill thru for bamboo stick (I like the BBQ sticks) one at a time and glue to block. I let the stick penetrate 1/4 inch and round the tip for easy insertion. You could also do this drilling procedure with only the first 2 sheet of the nose so that the bamboo peg do not protude on the nose sculp. Then you add other sheet to make your total thickness needed.
Fourth
After all the stick are in make sure you do one at a time and glue (thin CA is cool because you can glue from the front without accidently gluing it to the fuse). There is five pegs in this one and it is almost too much. On the RL 16 of Luc he only has 3 and it is still perfect (in the case of the RL 16 this technique was a must because there was not enough space for a normal plug).
When you drill the holes, keep them has close to the exterior of the bulkhead then you can remove a lot of wood in the center of the nose for easy rubber access.
Fifth
Sand the nose to fit the fuse. I use thick tape to protect the fuse while sanding with heavy grit. I change to just masking tape as the shape gets closer. You can also put a wrap of masking tape on your sanding stick so it ran "ride" on the fuse tape and not "sand".
Final product
If you need more space for the rubber or want to reduce weight, you can sand (I use a Dremel) the bulkhead and leave only 1/2 of the holes, it will still be very tight.
