Two pumps config - serial or paralell?

[Puzzdre]

Aaaarrghhhhh...

Just like BillA said, Zeros are the most expensive numbers...

[MadDogMe]

Hey Puzzdre, you can use any size barbs on the sensor,use a reducer, does'nt matter if the sensor is restrictive cause the other channel is open for flow, as long as you get enough going through the sensor to show movement alls OK ...

[Puzzdre]

Yup, that will do, now I have to find agood Y piece with somewhat 10 - 12 mm ID. That won't be so easy, cos I cannot buy one here, dunno if automotive parts stores have that kind of stuff. Maybe I'll make some somehow.

And seeing Volenti's solution for one way valve, I'm going to make one too...copycat...

[Puzzdre]

Just a little update...
I'm gonna try both setups, serial and paralell pumps then decide which one to go...

Chipset block on the way...pics (more like scans cos I don't have digicam... )

first, grid on the chunk of copper
(somebody pls. enlighten me, how to post multiple pics in one post )

[Puzzdre]

punched start holes into grid, removed the sticker, drilled and...

[Puzzdre]

and ofcourse, forgot to attach the pic...stupid...

[Puzzdre]

both halves, looking better in real than put in scanner and scanned...:shrug:

can't wait to see the finished block. so far it seems relatively doable with a drill on a standard; so long as , like u did, let someone else dimension the copper piece as needed. chipset and gpu blox don't seem to need ultra performance, just a good amount of flow.

btw, multiple pics can be done if u host them pix on some personal webspace and use the 'img' tag to adress the http'z of the pix.

[Puzzdre]

Thx m8!!!

I thought that for multipic's I'll have to put them somewhere else!

As for the block, just picked my copper from machine shop, all perfectly sized and flattened. That will be the base for cpu block.

This one on the pic's I cutted myself with handsaw (had some 40 mm wide copper bar), sanded a little, than drilled today.

I think that tommorow I'll have enough time to drill one cpu block, and post the result.

Cheers!

oh yes. looking good... I see you had a little bit of a problem with some of te holes, drifting..... did you punch each hole, before you drilled, or did you just drill right through the printout...

[Puzzdre]

Hi #Rotor,

Yes, I punched all the starting points, but drifting is caused partially due to my cheap drill press, paritally due to my 'puncher', I couldn't find any better (at home, without going to the store), so I used one bullet (12.7 mm slug) I had from past times, thought it would serve a good purpose at last , so the centering was mostly good, except in few holes. The worst holes are my first drilled, I put too much pressure on drill so the drill bit drifted towards neighbour hole. The others I drilled with less pressure on the end, turned out good.

This will be the chipset block, so I made it first, to make less mistakes on cpu block.

I thought that I'll be able to drill cpu block today, but it's snowing and pretty chill on my balcony, so dunno would it be done today or tomorrow.

Thx again for all the advices!

[g.l.amour]

so basically, all you are using is a cheap drill press?

[Puzzdre]

Yup, with some good quality drill bits...simple, fun, nice results, fun, and ofcourse, fun.

allow me to say, this manufacturing method is by far, the cheapest, as far as high tech equipment goes. it is also the most versatile as far as design options. It is the soul reason Why I can literally, in a matter of 10 minutes, communicating with someone on the other side of the world, design and finalize a 100% customized block,


to put it in another way.... If I was AMD, I would have been able to build you your CPU, to your spec, via Email and I would have been able to do so for less than the norm as far as mass produced product available.

and it's all thanks so this manufacturing method. It took me 4 years to get it fine tuned, And I'm still improving every time I make one.... the beauty of this.... doing it with CNC would greatly enhance accuracy and speed.... but it is absolutely not a requirement. a Steady hand and eye, and you will do just awesome... as them pictures prove, That for a very first effort... is way much better, than my first effort... My first one, ended up getting the hole cavity cleaned out... none of the holes was where they should have been

[Puzzdre]

Wow!
Four years! Another thanks for sharing the info on manuf. the block! When somebody puts that much time in something, and literary gives it to the people, what can I say, BIG THANX!

Thx for encouraging words.

Tomorrow I'm going to buy a nice plexy shield for my face, and remove that crappy blurry piece of plastic shielding drill chuck, one cannot see anything through that.

One question though, I have couple of 3 mm mill bits here, would it be any improvement if I try to drill the holes with those flat end mill bits? It would be much trickier to centre the bit over the hole without xy table, but is it worth to try?
