| [title] Learn from my mistakes (!) | |
| [* 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 frame around, 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 so much that it was moving neither back nor forth. Pulling its end with a caliper didn't help. |
| [* black] Wipe off the nervous sweat, 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 tip: | |
| [* 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 diameter 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 | |
