Indeed I am very new to this but learning quickly :)
Just fin soldering 10 copper 90's to some smaller pipe - the elbows were the socket type, not the street one, which would have been better.. They all have good joints but some of them have lots of solder around the outside which I need to clean off.

Also just made a heatsink from sheet copper. 15 pieces 45*15mm peices of sheet tinned and then clamped together, and heated again to join them. They are only joined at the bottom - I will bend the top parts of each fin apart for better air to copper ratio. Its very top heavy - the outside fins will be bent all the way round to stabilise it against the card. The bottom is filled flat and soldered to another peice of sheet of the same size. This is to cool a chip giving about 5-10w under the heatspreader of my 9700np. Im pleased with how it came out but I could have done it better. It would look better if I didnt reuse scrap copper from another project, so no pics :P

going to make my hdd cooler soon. Heres my plan:
Use flattened copper pipe to make sheet (my dad can squash it at work)
make two sides of the pipe flat for better strength/conduction - the ends will be left how they are to make hose easy to attach.
the only thing I need now is the hole locations for the drive, I dont have a spare to get measurements from. The drives im using will be maxtor dmp9

here ya go...
only measured with a ruler...

thanks, Ill try to start making it tomorrow :) (will have pics!)

The stoc.... oh alright, mine (and probably a LOT sooner too)! Fair points, well made :)

I know what you mean, but pushing people to try things should always be encouraged in my opinion. I wouldn't call myself skilled, but comparing what I was capable of when I started water-cooling to what I can do now, there's a big difference. Most of it's due to me trying 'crazy' ideas that my buddies all said would fail / leak / destroy my house ;)

My progress....

Got the annealed copper sheet, also messed up one of them, so I left it for 4 mins on the gas stove of my cooker, and managed to get it glowing bright red :D so now its soft enough for me to start again.
The problem is bending them all the same. they bend easly, but theres no way atm to get them the same. Im thinking of maybe making a mold in clay of how I want it. Then to anneal tehse the most I can, then hitting them into the mold, how well that would workI dont know, and I doubt clay would be much good either, unless I could get these to anneal more.

Maybe try wood for a mould if you can - it's less likely to shatter than clay.

I would tend to agree on making the die for shaping the copper out of wood or possibly steel. You might also get better results if you can make a pair of 'male and female' molds that you can press the sheet in between rather than just beating it into one with a hammer.

Another thing to consider is that you will probably want a 'reference edge' on the mold that you fasten your part to so that the material in the bend all comes from the other part. This should give you better results than just random bending. (or make the raw peices oversize and trim to fit)

decided random bending was easyest. I thought I could get my dad to make a mold by squasing a steel rod into some aluminuim but decided against that (aluminim strong enough?). Today I soldered it together after giving up witht he random bending :)
In the pics you can see they are bent different amounts but I think there close enough after bending them more with plyers and squashing the ends flat in a vice. The ends need trimming a bit I cut them about 1/2" oversize. Also might cut the 15mm pipe off the ends and put 12mm pipe in for the barbs

Looks like good work, should do the job well.
