Default Professional Lapping Service

If you need your heatsink or waterblock lapped, don't do it by hand. It will not be perfectly flat as the human hand cannot make it perfect. So heres the solution. I can lap your heatsinks/waterblocks to be perfectly flat. We are talking within a millionth! It doesn't get any better than that folks. The finish will be GREAT! Anywhere from 1000 to 4000 grit! So your probly thinking 'This sounds great but I bet it will cost me a ton of cash.' Well thats not true! I can lap it for $30!!!! All you do is pay the $30+ actual shipping and you will improve your temps like magic!

It will take about a week to be lapped then fingure in shipping depending on how close you are to Ohio. So send me a PM now and get it shipped out ASAP!

Yeah, id pay 50$nz + shipping for what is quite probably a 0.2 degree difference.

Agreed about the FS section comment.

Seriously, does it even matter having it that flat? When you use thermal adhesive (arctic silver) between the copper block and the cpu?

Flatter the better, but $30+ shipping is asinine.

Heres how I see it, To make it worth the time of doing, you almost need it to cost that, otherwize its a favor and probably loosing money.

I see absolutely no reason for absolute flatness when you cant see the difference between 600grit and higher.

I spent about 1 hours and lapped my block up to 2000 grit...
it may not be 100% perfect but i had a nice mirror finnish...
and the sanding papper only cost me 3-4$...
I don't think i'll get much noticable temperature improvments...
I'll pass...

Ya'll... this might come in handy, if it could be verified... But that aside, I've got a couple of heat dies that are going to need a serious lapping job.

Ben, those heat dies should have had a system for lapping built into it. Sending the heat die off every month for $30 isn't going to be cheap. Anyway I know how to do this now if you want hints.

Ben, Im pretty sure its pretty impossible to get a heatdie as flat as your thinking that small without lapping before machining.

The one I made for you is about as flat as it will ever get.

JD's on the right track; it's gonna need maintenance.

Nickel plating is starting to look good, but I'm not past redoing it in steel, if it helps.

Either way I'll start with the copper unit that Jon made for me. There's so much work to do with that one alone.

That info right there helps to verify that you are a regular member of a forum, not a scammer. Makes it easier to find this so we know who you are

I wasn't referring to the honesty of the person... I was referring to the end product; how can it be verified that it has been lapped to the "1000 to 4000 grit".

An outline of the procedure would go a long way. Follow Bill's lead above.

What I understand, from talking to people that grind lenses and mirrors for telescopes, hand lapping is the best. No machine can do as good a job as a properly lapping job done by hand.

The reasoning behind this is, a machine is really good at doing a specific job the exact same way every time, but that doesnt make for a good lapp job. A good lapp job is done by introducing randomness into the lapping process, which is what the human hand is best at.


This is why all those cheapo telescopes you can buy at the Discovery Channel Store at the mall are all machine lapped, whareass good expensive telescopes are all hand lapped.

you posted words
???
a question may be responded to with words, as you have done
but your words are without meaning
it seems clearly you lack the info even needed to answer intelligently

perhaps you DO know the answers, lets try . . . .
who says that s17 kiows all about lapping ? (you ?, ok, what do you know ? about s17 ? and about lapping ?)
do you do lapping for a living ? who does lapping for a living ? are all lappers equally qualified ?
testing ? what kind of testing ? to what criteria ?

you should look up QA and QC, the answere are there

if this was a test, you failed

You scan the surface with an interferometer or a profilometer, which will give you a verry accurate contour plot.

That would constitute testing for flatness.
