Adventures in lapping - Page 8

post #71 of 88
Thread Starter 
no probs guys, this thread seemed long dead anyway, a few bumps won't do it any harm

beelzebub_75, I know EXACTLY what you are talking about, the sucking to the paper was happening for me also.... I was working on the lapping in a place I couldn't have a constant stream of water so I didn't bother using water at all. I just dry sanded the base and every time I went to change direction or give my wrist a break i'd blow off the copper shards with a can of compressed air, then wipe down the sand paper with some lint free cloth. It worked well for me anyway, I got all the bases I lapped flat and shiny.

FOR SALE!!!!!!!!!!!!!!!

Brand new home style lapping apparatus. Only one owner, took great
care of it! Asking $500 OBO.


Ha!Ha!Ha! All it takes is an old fish tank propped on its side, an old piece of tabletop glass, an awesome Premium Lapping Kit from easypckits.com, a 25ft piece of garden hose, and the all important "squirt gun" nozzle. It actually kicked buttocks!!! It kept water between the sandpaper and the HS, and it also rinsed away the slurry. It did a pretty fine job as you can see on the third pic.

Nice job at being creative. :-) I have customers all the time that tell me they lap under running water. It is a very effective way to remove the slurry and to help ensure that coarser particles are rinsed away well before you move on to the next finer grit.

so between grits when cleaning with water, do you dry off the block or just keep it wet and carry on to the next grit?

The times that I did use water, I had a sponge and a damp cloth that I used to remove the water between grits, and occasionally before grit-changes.

Lapping by hand is a "low rpm" event - not too much heat is produced so removing excess water is not an issue. It also helps me see what is going on, and what the condition of the sandpaper is.

Now I just do it dry.

If that's all you have then that's all you can do. Stopping at 600 would be alright, but of course going higher would do a little bit better. I don't know exactly how smooth your Heat Sink would be after 600, but give it a shot. Unless your Heat Sink is already pretty flat and shiny, if it is then don't bother until you can get finer sandpaper.

The main goal in lapping is to get your Heat Sink as flat as possible. Once it's flat then you can start working on getting it shiny... 'cause the shinier it is the less valleys and divits you have which in turn means more surface to surface contact.

no the heatsink on the arctic is so rough and its not flat because i put my ruler over it and there is a gap in the middle, thats why i want to lap that thing, i get really bad temps it gets so annoying. so going beyond 600 grit is just for show? or does it improve thermal interface?
