slask111 Posted April 7, 2012 Report Share Posted April 7, 2012 HI all, I am home alone working this easter weekend, so ofcourse i started to fiddle around with my 390 (instead of working). I love the watch, but i am not happy with the CG or lever pin. The CG inner walls are uneven and the leverpin is not flushed with the CG or polished as the gen is. Been sanding away and polished the lever pin, but i dont dare to do more. It is really, really hard to get the lever pin surface flat. When you sand down your lever pin, how do you do it? Below is a gen 390, and mine. I would say its a big difference. Happy easter boys and girls! gen Rep Quote Link to comment Share on other sites More sharing options...
slask111 Posted April 7, 2012 Author Report Share Posted April 7, 2012 I did some more work on the pin, it looks a tad better now. Really, really hard to sand the surface by hand and get it totaly flat. Might go over it with a dremel later on. Quote Link to comment Share on other sites More sharing options...

slask111 Posted April 8, 2012 Author Report Share Posted April 8, 2012 LOOoove mine Wow that pin looks great. Did it look like that OTB? Here is mine. I think im happy now. Dont dare to sand anymore using my hand. The egdes gets rounded so easy. Quote Link to comment Share on other sites More sharing options...

projectologist Posted April 8, 2012 Report Share Posted April 8, 2012 I finally took the pin out and chucked it up in a collet, then attached it to a drill press. A dremel tool will work as well. To keep it from getting slightly beveled (I wanted it dead flat per gen), I left very little exposed at the end of the collet. I had various grits of wet/dry sandpaper mounted on a flat piece of scrap aluminum. I made sure the sanding block was secure and perpindicular to the collet as it was lowered to the sanding area. Once the pin was sanded flush with the collet head, I polished it and then re-installed it slightly recessed (automatic since it had been slightly shortened from the sanding). I also sharpened the inner corners of the CG body. 1 Quote Link to comment Share on other sites More sharing options...

I also sharpened the inner corners of the <acronym title="Crown Guard">CG</acronym> body. Great job there. Im going to try the dremel as collet and sand away. Easier to get a flat surface if you sand it down to the collet edge as you did. Thnx for the tip. Just sandpaper to sharpen the corners of the CG or with a dremel tool? Im really scared to sand of to much Quote Link to comment Share on other sites More sharing options...

Londongeorge87 Posted April 9, 2012 Report Share Posted April 9, 2012 (edited) How do you sharpen the inside edge corners of the CG? Got a few pams I could do this to Thanks for the write up Sent from my iPhone using Tapatalk Edited April 9, 2012 by Londongeorge87 Quote Link to comment Share on other sites More sharing options...
slask111 Posted April 9, 2012 Author Report Share Posted April 9, 2012 I started out with a square file to get the edges straight, then moved on to sandpaper to sort out the rough edges that the file made. Last i used a nailfile for the finishing touch. I just took of the CG from the case and placed it firm in a movement holder so it didnt wiggle around. Im curious how projectologist did it though, his CG corners are perfect. Quote Link to comment Share on other sites More sharing options...
Londongeorge87 Posted April 9, 2012 Report Share Posted April 9, 2012 Thanks, will give that a go for sure. I am also curious how projectologist did his. CG looks brilliant.

Please share your technique with us if possible P Sent from my iPhone using Tapatalk Just getting back online. For those corners, I used a couple of micro files from the set below (actual file surface is only 50mm long). I went with the finer mesh (also available in 120/140). After going through a couple of cheap sets of diamond files found on ebay, I decide to try a better quality... HUGE difference! I take it very slow and have the CG body, sans lever, solidly clamped so both of my hands are free to steady the file. Also make sure you have good lighting. Here's a link with more info and where I purchased them... http://www.riogrande...es/114803?pos=7 Quote Link to comment Share on other sites More sharing options...
