I put the mica & gaskets in first, then install the needle bar, adjusting the needle bar arm until the screw hole lines up with the mica hole. With one hand, I have my jeweler's screwdriver with the screw hanging on the end, with the aid of a small dab of grease to act as a minor "adhesive". With the other hand I pull the needle arm away from the mica slightly, then insert the screw in the diaphragm hole. While turning the screw, using the mica as a support, I bring the needle arm up to the screw and the screw usually starts right in. A small Q-Tip to wipe away any remaining grease, then the wax...

My technique is very similar to Jerry's. Instead of grease, I use a small blob of bees wax warmed by my fingers and rolled into a ball as the "adhesive" to hold the screw on the tip of the screwdriver.
A good quality screwdriver helps. I use a Wiha screwdriver for this.

Just magnetize the screwdriver , holds the screw perfectly , also useful when refitting Edison motor gear assembly where screws are difficult to access !

My method is a little different: I put the screw in the hole in the mica, then place a piece of Scotch tape over the screw to keep it held in place. Then I take the mica with screw attached and line it up with the needle bar and rotate the whole thing to start the screw... Once started, I remove the tape and finish tightening the screw... This works great for someone with a shaky hand and less than perfect eyesight.
