Alright, I have decided to perform a small operations and take some pictures. So here you go on a step by step procedures on tightening back the screws. You will need a phillip screw driver (the one you use for glasses), some cloth or paper towel to prevent scratches of the cups and a very calm mind. The whole procedures took me about 10 mins.
EDIT: You can actually turn the leather pad anti-clockwise to remove the pad. Push it tight and turn it anticlockwise.- Thanks namaiki for sharing. So now just skip straight to step 6 and finish at step 12 and then put the pads back.
1) Pinch on to the base of the pad and slide out the leather pad with your thumb.
2) Pull out the leather pad
3) Leather pad removed in 5 secs
4) The white plastic ring is the one that holds the pad. Do not remove the white plastic ring.
5) Pull out the round grey sponge. Its not glue or attach to anything.
6) There are 4 screws around the cups, removed all four.
7) You will need a small phillip (+) srew driver .. the same one you use to tighten your glasses. Its a phillip screw head.
8) Ok cups come off exposing the driver. Notice that there is some cotton material in the cups... don't loose that..
9) By now, you should have all 3 items removed... don't loose the screw or you're screwed
.
10) Notice the srew driver is not perpendicular to the screw. I actually remove the screw bit to shorten it.
11) By using the screwbit without the driver, I can actually do it perpendicular to aviod destroying the phillip screw head. you can still screw it at an angle, just don't screw so hard or it will mess up the thread. Below are my screw bits
12) Time to box it back. Put the screw first and place cup over it. If you place cup first, the holes on the driver and cup is pretty hard to get it align right. Once one screw is in, the rest of the holes will align itself. - WARNING - do not screw hard, gently screw until it stop. Use baby strength
13) Once all 4 screws are secure to the cup, slide the leather pad edge onto the white plastic. I use the screw bit and make a small gap so I can slide in the pads easily.
14) The pads took me about 3 mins. The trick is to pinch the leather ring, pull up a little and "hook" it onto the white plastic ring. Once each section is done, slide the screw bit forward and repeat until the last inch. Removed the screw bit and do a final "pinch up" and "hook it in.
15) Align the leather pad so that the horizontal lines on the pad is near the bolt. You can pull the pad to rotate it.
16) Now its all box back without a scratch.
17) Sit back and enjoy a cup of coffee with Miles Davis.
Misson accomplished..
