| - | [* black] Learn from my mistakes... 1. Alignment / filing: re-inserting the pins takes considerably more force than getting them out. However, as always, too much us too much - the problem being, if you do it for the first time, you don't know what is too much until it's too late. I had heard this can be a problem and had ordered extra pins just in case. |

| + | [* black] 1. Alignment / filing: re-inserting the pins takes considerably more force than getting them out. However, as always, too much us too much - the problem being, if you do it for the first time, you don't know what is too much until it's too late. I had heard this can be a problem and had ordered extra pins just in case. |
| [* black] At my very first try I didn't file the inside of the nose bridge bore much. Result: I wasn't able to push pin fully back in. I turned the nose bridge, pushed it back out, tried a new pin - it worked. | |
| [* black] On the other orbital, I had the same problem but couldn't even get the pin back out. It had deformed some much that it wasn't moving neither back nor forth. Pulling its end with caliper didn't help. | |
| [* black] Wipe the sweat off, place the frame in the bench vice, get a 1,5mm drill and very carefully (!) drill a hole in the pin from the front. Make sure you don't touch the walls of the nose bridge bore (2mm diameter) - you don't want to widen the press fit. Just pretend to be a dentist. When removed enough material, you can pull the culprit out. | |
| [* black] Moral of the story: file, but don't grind. If the alignment isn't perfect the pin can get caught and will deform when pressure is applied. | |
| [* black] 2. Grinding down the pusher pin tool: | |
| [* black] Again, on my first try I hadn't done this enough (since I didn't know what was enough and how much is too much. 1.3mm seems to work). This can result in tiny spot marks on the back of the pin. I don't mind (especially since Oakley's original work didn't seem very quality oriented either), but since you're at it... grind it down | |
| [* black] Additionally you can try placing cardboard between the pusher tip and the pin. Some people of gone as far as machining tips with a wide end for re-insertion. |
