pardon me for being so n00bie ; but isn't the dremeling really stressfull? i mean, if u got a baseplate thickness of 3mm at the least and 5mm at most. if u cut too deep with the dremel...

looks like it is a messy job. are all yours made with dremel rotor?

Puzzdre · 11-09-2002, 03:57 AM

With dremel you go as deep as needed to remove the walls between holes, not cutting deeper into the block, leaving the little conical pits made by drill bit head. In blocks I drilled so far, the holes are (more or less accurately) 4 mm deep (thx #Rotor!), so it leave you 6 mm for base thickness. Cutting the thin walls is relatively easy, but cutting into the solid block with dremel is...

Rotor,Puzzdre, how about splashing out on one of those metal cutting blades that were in BB2K's radial thread?. $25 if I remember, but worth it in the long run?...

g.l.amour · 11-09-2002, 04:43 AM

isn't 6 mm alot for base plate thickness? i thought 3mm was considered to be optimal, or are u getting structural integrity problems then?

btw: anyone know what's up with rotor's site?

Puzzdre · 11-09-2002, 09:52 AM

@MadDogMe: yeah, good idea but 25$ is only for blade, and additional $$$ for arbor and stuff is becames too much IMO. And making something on your own for using that blade is IMO dangerous (lots of sharp teeth, moving fast...Alien?

)...it's doable and good for long run, but the question is would it pay for itself...dunno

@g.l.amour: I accesed #Rotor's site today without problems.
As for base thickness, I just listened to #Rotors experience. And according to this graph, 6 mm base is quite good if you want heat to spread good. Or, am I wrong?

I did a little cutting on the block today with 1.5 mm mill bit on my drill press, moving slowly the block and cutting the channels between the holes. Now my hand hurts cos' I held it firmly. It's time consuming and there's a clear and present danger of breaking the bit, but I did it as an experiment. I'll post the pic (I hope so) tomorrow of one half of the block cutted this way...

Cheers

i will need to save this thread to my hdd somehow, its gonna contain all the info needed to make a cheapass, good performing block.

i will try rotor's site again. is it the dns2go url you got?

Puzzdre · 11-09-2002, 01:02 PM

Ooops, I cannot reach the #Rotor's site now...you were right, something IS wrong... Today morning I accesed it through the linked pic's in this thread, but now is not available...

the link points to
http://3rotor.homelinux.com/images/c...04482.JPG.html

but it's not working now...:shrug:

If you wanna I'll email you all the drawings I made in corel .cdr file (all the drawings of the blocks), just say so, no problem...

#Rotor · 11-09-2002, 03:12 PM

is it working now..... ? sorry

I'm no longer with DNS2GO....

use this one...
http://3rotor.homelinux.com/

you can also use any of my old links, and modify them by replacing the dns2go with homelinux

the rest of the url is still the same.

yes I cut all my blocks with the Dremel. those metal cutting disks are nice but they are too thick and the diameter on them is too big. Makes it impossible to get close enough o the sides without cutting into the sealing surface around the outside...

one thing, do not try and use those expensive Carbide/diamond wheels for Dremel... I tried one, $36 down the tubes....

they are meant for stuff like glass and ceramic. copper just destroys it in less then 10 seconds.

as for the effect of base thickness on the performance of the block, it absolutely depends on the design of the block. It is not a one size fits all affair. What might be true for a Maze3 will most definitely not hold any water with this design....

No PUN.....

Puzzdre · 11-09-2002, 03:21 PM

Yup, everything is fine now!

All those pics visible...again...

g.l.amour · 11-09-2002, 03:55 PM

testing some designs in autocad, man, it is more complicated (fun) than i first thought. every drill hole i drew, creates new problems for the next. i now realise that the designs u guys have are carrying more thought than i initially thought.

thx for the url

Puzzdre · 11-09-2002, 04:07 PM

Any luck with finding thick copper bars?

g.l.amour · 11-09-2002, 04:25 PM

got some addresses. will start calling around some starting tuesday. will be hard finding the small amounts usefull for us hobbyists. most important part is that i got the addresses ;-)

btw, do u have a sketch of the block when it is finished puzzdre? i imagine something with one inlet and 2 outlets...

can't wait for some new pix (or is it snowing on your balcony again ;-) )

edit: at rotor, got to your site again, and i feel kinda guilty for seeing that many good ideas out there. so , my Q, u seem to use no O-rings nor solder paste. are they well sealed like that with just the bolts tightened?

Puzzdre · 11-09-2002, 04:25 PM

Anybody, pls help me with this:

1. What diameter are the holes for holding the block to the mobo (I mean what dia I should drill through my block)?

2. Tapping (sp?) the holes - if I want to make the two halves of the block held together and reinforced with screws, like #Rotor have on his blocks, and if I want to tighten the halves with 3 mm dia screws, the question is - what dia should be the hole for tapping it to accept 3 mm screw? I found some taps (packed in 3 pieces, I presume that is for making initial thread with first, and advance in lateral thread depth with other two), but no info on what dia the hole must be for 3 mm screw. I know there are different kinds of threads, but this is something ordinary tapping set, sorry I didn't remember the thread size/step info from the box...

Pls. help!

g.l.amour · 11-09-2002, 04:32 PM

don't mind the outerlines, they are rough dimensions of my maybe to-come WB

dia is 6.1mm, well, u'll see

edit: i presume you are talking socket a dimensions (u r always talking cost effectiveness, lol, athlon is the way to go)

taken a bit from here:
http://www.dansdata.com/images/coolercomp/holes500.gif

and from here
http://forums.procooling.com/vbb/sho...es+motherboard

took me about 2 hrs to find that info (was looking for xact same thing today)

Puzzdre · 11-09-2002, 04:41 PM

g.l. : for copper in small amounts, did you try to get it from machine shops, maybe you can use some of their leftovers?

No sketch I'm affraid, only in my head (and yours too, cos' you got it - it's central inlet, two outlets!). I must cut it than bring it back to the machine shop for drilling and tapping the large barb holes and also, they will make the barbs for me (I cannot buy them fabricated anywhere)

I'll try to finish one half tomorrow to post the pic, today I tried cutting through the holes in one of square pattern block half, but didn't manage to finish it (about one half)...

Yeah, it is cold on the balcony but nothing that doubling the socks, pants and other stuff on me won't beat. Today I got myself one plexy face shield, a little addition to safety...No snow for now, just copper flakes on the floor
