Just practice on Lapping HS.

post #1 of 11
Thread Starter 
I received my lapping kit today. It has 220 grit, 400, 800, 1200, 2000, 2500. So I decide to practice on my old HS, before lapping my TRUE. I lapped it two times, but it's not mirror as other people. Is this mean the HS is not flat enough to have good mirror look?

Here are the result.



New Pics.

Use graph paper to reflect the lines. If the lines are bent/crooked, it isn't flat enough........

Next time please if you can take pics in macro mode (better for closeups), and remember that mirror finish isn't what you're trying to go for it's the flatness of the surface so it can have more surface contact or something like it.

Any comment on this Lapped HS? or How to get better mirror finish? I lapped this HS with dry sandpaper. Should I use wet one? some people prefer using Hand Dishwashing Liquid, is that better?

I like to wet-sand for mirror finish (and yes, a drop or two of dish soap help to reduce friction so you can sand better).

However, though mirror finish is nice and pretty its the flatness (or lack thereof) that determines what your temperatures will be like. Since you'll never see the finish once the CPU is in anyways, I personally don't worry about it anymore. The first few times it's fun, but a hell of a lot of work to keep doing.

That is in no way a bad lap. FYI, the secret to the true mirror finish is NOT sand paper. Go to a drug store and buy one of those pink and black styrofoam nail files\\polishers. That's how you get uber mirror finish. The flattness looks great based on the snapshot with the graph paper.

Your flatness looks fairly good. A mirror finish will not improve temps to any noticeable degree.

I prefer to use a drop or two of 3-IN-ONE Oil for lubrication once I get to 1000 grit, and I only us up to 1500 grit. Looks like you did a good job, but if you want it shiny obtain some 2000 and 2500 grit paper and use some lubrication.
