Very nice ricky.
I like where you are going with this evap, it looks really promising.
I think 2-3 steps like you have is enough. After using the @itor evap I see that weigth and size makes not much difference.
I think the design of the bottom step is 90% of evap performance
ready to brase :)

And don't appologize for excessive pics in your own thread. Just add a warning to the subject if ppl complain.
did you lap on a glass plate? on the picture with the reflection of the camera you see that at the edges the reflection is disformed. This suggests that the bottom is not flat but a little bit rounded. The other possibility is that it is just an effect of the camera's lens that cannot compensate fully for spherical abberation at that short distances. If the reflection is also disformed when you look at it with your own eyes I think you need to lap again.
it was lapped on a glass plate, it is not rounded for sure, i'll try other pics :) the evap is on sl4ck house :)
not rounded for sure ;)
3 sand paper kinds @ glass plate, lapped @ hand, 3 polish kinds(fast cut, fine, super fine) and @ last Duraglit. Maybe it's a camera efect
then it is probably just the lens :) good to hear, would be a shame if you had to do it all over again ;)
ehehe this is only to make cold, but why not make it look better?
laped is good and is must be maded for all evaps
and yes, this is absordly well polished the problem is that sl4ck work is good, he dont have to many work lol :D
Impressive evaporator Ricky, i really enjoy watching it.
thanks berkut, i like the way you see the things, so if you like it it must work good :)
Very nice evap Ricky!! What sort of sand paper have you used to get that mirror effect on the face?
the last was 1200 i think, sl4ck have all the merit on this lapping :)
1200 :eek: ! I've been using that on my evap for about half an hour and still cant get anywhere near as good effect as that! Any tips ?
sand paper(240,600,1200), car polish(fast cut, fine, super fine), duraglit, and most: strong hands :D
If you have a chance can you please post a pic of the tooling you used to make the evap [ricky]
This sort of thing makes me wish that I was back at home with the lathe and milling machine.
i'll take pics, you refere to the "knife" that "cuts" the cooper right? we made some i'll take pics!Quote:

So pressing on more when sanding gives a better finish?Quote:

After you finished lapping clean your evaporator thoroughly with ATF and at last isoprophyl alcohol. Should get better temps..
use "wet" paper and keep the surface wet, you do need to go in steps of about 200 grit. buy good 3m paper. If your doing it by hand expect more than 30 min.Quote:
