Ok, so… I didn’t want to wait weeks for valve shims, and I also didn’t want to pay 10-22 dollars each for them. I called around to a few vendors in the states and no one had the sizes I needed. So I made my own (did a few tests on the shims I pulled from the car to determine surface finish, hardness and material): 1. Started with a 6 feet of 1/2" 52100 bearing steel rod. $15 2. Using a CNC lathe, turned the OD to 12.3mm 3. Using the same CNC, chopped the rod into discs of varying thickness, about 40-50 total (no pic) 4. Sent the discs out to a local heat treating facility to be hardened to 62-65C (pic below, left) $50 5. Used a surface grinder to take the shims to within .0005" of what I needed. (pic below, right) ![http://img.photobucket.com/albums/v516/ctnewman2/IMG00076.jpg](http://img.photobucket.com/albums/v516/ctnewman2/IMG00076.jpg) ![http://img.photobucket.com/albums/v516/ctnewman2/IMG00077-1.jpg](http://img.photobucket.com/albums/v516/ctnewman2/IMG00077-1.jpg) Here’s a little video of the surface grinder in action. If you look closely you can see the sparks flying. The table moves left to right then indexes forward and backward. Once it has completed a whole plane, it drops down .0005" I could have incremented in .00025" steps, but that seemed like overkill, since nissan specs call out +/- .001" ![Explore christian newman](https://img.photobucket.com/albums/v516/ctnewman2/VID00002.flv?width=480&height=480&crop=1:1,smart) ---

Plus the stuff works, and it is accurate, so who really cares how old it is? Production is where the nice machines are, but nice machines are purchased to make money not sit around collecting dust like these do sometimes. These machines are retiring slowly lol. ---
