Good suggestions Phil, well you can see, I am not a regular user of "Bounce" sheets! Hi! But I do use the air puff to move a meter needle up scale, when I want to check the action, a gentle puff from the bulb syringe or photo lens cleaner. Paper is good I guess, but I did see a needle or two pop off an armature even if rotated gently. Of course, those were not glued properly to start with. 73, Stuart
