Two teensy screws; One for the barrel cap - the other for the barrel ratchet. Handling them many times during the evening as I have a challenge. Not a big one. Threads in the barrel for the cap screw are stripped. Closing the bench for the eve looked down and - UH - OH. Only ONE! He was quickly located. He wandered a few inches away onto the counter. Out comes the magnet. I won't have that problem again.
