I recently read a guide on lapping and most of the things mentioned are fairly straightforward and I already have, or can get easily. Sandpaper, a sheet of glass, parts wanting lapped, etc. But it mentioned using "Low Smell" kerosene as a lubricant/cutting agent, and I've not a clue where to get something like that, or if there is a more widely available alternative. I checked into using water, and the gripe was the paper curling as it dried, and looking at the lapping guide in the sticky, you can see it there, I could do without that.

It's going to be a first attempt, and I'm guilty of following things to the letter until I have personal experience with whatever I'm trying to do.

You don't want sandpaper, you need wet and dry paper.

A peice of glass or anything smooth and very flat like a granite chopping board.

Stick down the edges of the wet and dry paper with tape and use a little water and that's fine.

Change paper regularly. STart with 800 grit and finish with 1200 or greater.

Do not polish when finished.
 
water worked a treat on mine whilst placing the wet and dry on the hob for a nice flat surface.. Just make sure it's not switched on. :D
 
Doubt it (also will mark the Cooker), go read all reviews and BTW Lapping was not invented by a 18year old PC geek, I did it in my Job for 18years.

What's so hard about doing what the reviews say ?, you buy the kit ready made inc glass on E-Gay, then buy kits without glass thereafter (cheap as chips).

There is about 100 Lapping threads in this forum and all ask the same Q's TBH.

Not sure if that was aimed at me or the OP.
I'm not in the least bit interested in reading some review of how to lap a heatspreader.
It's done - it's on and it's a dam site flatter than it was before.
Half of what you read on the internet is ball cocks anyway. :D
 
The other have may be worth reading if the person is not too ignorant to think he/she knows better than Engineers who lapped before PC were even what they are today or PC Geeks who write the guides.

Click to expand...

Not ignorant, just feel that I have enough brain power to work out how to do it myself without having to consult the interweb first.
Getting a bit of copper flat is hardly rocket science.
 
Did I say you were actually ignorent (even though you are both that and bigheaded if you are so clever you do not need read any reviews). ;)

Anyone here who tells someone to Lap on a cooker hob or kitchen worktop will see me post bellow it to use Glass or marble if you must.
 
Like I said, hardly rocket science to get a bit of copper flat. I don't feel I need to "read up about it" I have far better things to do with my time, that includes arguing the toss on a forum.
It probably could be flatter if I researched more, became some specky geek about it, however I'm more hands on and down to earth than that.

nite nite. :D
 
well tbh I would spend a little while researching something before taking sandpaper to my £150 piece of kit..

there are ofc many ways to "lap" some better and more time intensive than others but I would not recommend anyone lap their CPU or Heatsink until they had taken the time to do some of their own research
