The front piece needs a hole to fit the lock in. If you buy the same lock as I did you can use the measurements on the pattern. If not you are on your own.
The strap holders needs to line up with the holes in the top strap. To find our where they should be lay the top strap "assembly" on the front piece and mark where the center of the "strap slots" are.
To cover the back of the lock I form a piece of leather (the same as used for the gusset) by wetting the leather and pressing it down against the lock. I cut it out in a circle with a diameter of 8,5 cm and skive the edges before cutting to the final shape of (7,5 cm diameter).
Rivet the lock in place using the same technique as with the catch. Apply contact cement to the lock cover and front piece and glue in place. After it has dried you can sew it.
To determine the height of the front piece I tried to fit the gusset with help of some clamps, It had to be 31 cm high and not the 30 cm I was aiming for.
