Where do you get your lapping surface?

[Bojamijams]

I know you're supposed to use a glass / mirror surface but... what would you actually buy and where to achieve this? I'm assuming none of you use your bathroom mirror so... where might one fight a 10 x 10 inch glass surface?

And yes, if anyone is keeping track, I've killed my 2nd E7200 with a bad IHS removal technique.. I'm just not gentle enough.. so now I picked up a Q6600 so as not to tempt me to remove it anymore (since the IHS is soldered) so I'm going with the original advice and just lapping the bastard

[Pellepel]

Got mine at an art store called Michaels in MN.

[evil-98]

i went to a glass store and got a 8X8 1/2" thick piece of glass for 4 bucks it was scrap

[StAndrew]

Just used a glass cover from an old pic frame.

Duhhhhhhhhhhh... I'm a moron.

Someone beat me with a stupid stick.

Thanks for the pointer.

[Big_Daddy]

only problem with that is, the glass in picture frames is usually very thin. (like 1/8") so not the best to use. if you do, make sure that you put it on a VERY flat surface.

[NaeKuh]

just go out to a hardware store and buy a sheet of thick glass. Its not even expensive.

I use my desk which has a glass surface on top.

[LagunaX]

I just use a hard plastic clipboard and lap on the kitchen counter.
600, 800, 1000, etc.

[SNiiPE_DoGG]

I have a big glass table thats 3/4 inch thick which I use. :up:

[RealRedRaider]

I used my glass coffee table...:D

4' x 4' x 1/2"

:up:

[Ashraf]

I use my glass computer desk. :D

[AndrewZorn]

I used a mirror... just be careful and you won't scratch it or anything.

[Waterlogged]

IMHO, your all using the wrong surface. :yepp:

I use a Granite Surface Plate I picked up from Harbor Freight about 8 yrs ago dirt cheap, it was like $12 for a 9x12x3. :D Sadly, they don't seem to carry them anymore but you can still find them pretty cheap if you keep your eyes open.

[bigslappy]

I know right?

I have a workbench with all my tools and stuff in the basement, but somehow I always find myself assembling my rigs in the kitchen watching the plasma screen :D

NAH you got it all wrong with That wimpy piece o' rock :rofl::ROTF::rofl:...

....One must BE comfortable while lapping ...:rolleyes:
.. as the Bling Smoked Glass Coffee Table affords the ease of use, & a large surface area in which to work.... I use a pillow to sit on also
I tape all the sheets of the various grits of sand paper (I really use Garnet emroy cloth it's more BLING & cuts faster ) side by side that way I can easly move from one grit to another grit & I also get a full lenght stroke using full sheets ...

:rolleyes:that glass is an Smoked'in' INCH Thick !;)

[veedubfreak]

Glass picture frame to tape the sandpaper to, then that on top of my glass computer desk. I was lazy and only did 400 grit for flatness.

[MpG]

Glass cutting board. Can usually grab them at any store with a housewares department. Just make sure you keep it separate so other family members don't wind up adding metal dust into your next meal. :D

use belt sander with very fine grit or file , only sand/file outer edge about 1/16 deep

then lap it

would that be stepping the IHS instead of lapping it ??

[kinghong1970]

ha ha ha... i removed the glass door from my tv stand, ya know thems tv stands with glass doors that covers the vcr and dvd player...

wife's wondering where it went...

[KaptCrunch]

sort of but getting more pressure onto the core taken down the edge on pillar of IHS, same results if stepping your water block

I would but I think someone beat me too it :slap:

I kid I kid!

Actually, it was my wifes idea (I was trying to use a 6 foot mirror I took off the wall :ROTF:).

I now just tape the sandpaper around the glass and tape it all on the table. Works great!

[IanY]

Take your LCD Monitor... just kidding... joking!! :D

If you have a framed college degree, you use it.. hahaha... that's what its worth these days :p: I got a couple of masters.. wanna borrowa couple? no need to return :ROTF:

[rjarois]

only one right way to do.....by hand, on a flat surface.....that means no power tools, and a granite surface plate. they can be had cheap, and are usefull for other projects. i got mine from a cheap import tool supply company. if i recall it was around 30 dollars. it is 24x30. please dont rip on me about the mess.....im in the middle of a project. randy.

Thank you for all the advice! I think I got a marble cutting block in the kitchen ... I'll use that ;)

It's about $30 with shipping, I wonder if I should get it...

Does an ULTRAFLAT surface over a SUPERFLAT surface really make a difference for something like this? I feel like the unexactness of the lapping procedure (ie, using your hand) is going to be the biggest factor.

[joecop120]

Lapping is weak...

I dont even have to use thermal compound.

http://www.surfacefinishes.com/

(I'm in IL, but you can find places that will diamond turn or optical polish stuff all over)

I had a fuzion v2 and a q6600 "mated", meaning they are SO flat, the surfaces practically stick to each other :)

Dude, I couldn't breath last night I was laughing so hard after reading this post...:ROTF: :rofl: :ROTF:

[AndrewZorn]

How could it be that funny? Again, I don't think the difference between a mirror and a real surface could possibly be greater than the difference in pressure your hand exerts on different sides of the CPU, even with periodic rotation.

you need to get a microscope to see the Peak's an Vally's of the surface

Hey, I set it on my lap and watch TV as well....:idea:.....hmm, guess that explains why my legs always fall asleep when I lap. :rofl:

Anyway, how big is this coffee table of yours?...now just imaging how heavy my surface plate would be if it were that size. :D :owned:

I don't mean to sound like a :banana::banana::banana::banana::banana: or anything but that's not a particularly great feat. I've done it many times on mass production work by hand lapping. All you really need is 2 perfectly flat surfaces and a decently shiny finish on both, then you can "wring" them together. Any half way decent machinist can do it. In fact, when I was in the 16 week machinist training course, we had to make our own set of parallel bars and one of the requirements to pass that part was to be able to wring them.

andrew, like waterlogged said.....i agree with him totally. if he isn't a machinist by trade, he knows his business......as he spotted a rough measuring tool on my bench. if you dont want to spend the money.....use the thickest hunk of glass you can find, and you will be ok. oh yea dont do the figure 8 stuff, you can crown your part very easy. i like the push lift, rotate part technique. duct tape your paper down.....i started with 400grit to get thru the nickel plate, ending up at 1200grit. to me flatness is better than non flat polished. flat and polished would be good also, but i just dont see a need for it personally. i use my Q6600@ 3.98ghz daily. peace, randy.

I lapped mine too, don't get me wrong... 800, 1000, then 1500, then printer paper on a mirror, taped down.

[Eldonko]

Printer paper?

[SNiiPE_DoGG]

Printer paper?

very fine abraisive, paper + toothpaste works wonders for fixing scratches on arcylic

[joecop120]

How much did that cost you, if you don't mind me asking?

It was free, as a friend at the company wanted to see if it could be done, and if it could be a future income source for the company. I would assume it would cost between $150-300, but I was never given any sort of estimate.
