the channels are 6mm deep .. with the water coming in the centre and going out of 2 of the cornners

 

Very nice machining!

What are you planning to make the top out of?

1 inch of HDPE ... so it has the potential to be interesting. However i've never tried to machine HDPE before

 

damn that should be an awesome block.

thanks .im hoping it will be .. it certainly will be very large and take 48 hours on the mill

 

It does have the right pattern to pick up a fair amount of heat though.

 

yeah i think it's important to have the coldest water coming in in the centre of such a large block

 

Looks restrictive! But should cool like a beast! I can't wait for more pics.

 

Well the more surface area the better imo. I just hope the channels are the right depth to retain a high velocity through the block (because that's going to pick up a lot of heat with that surface area). I suppose it's up to to testing.

i would think this block is very UN-restrictive actually

Dont for get that when making a TEC block you heed to ensure all of the block gets roughly the same flow becasue the heat is roughly = arross it's surface.

this is very different compared to a CPU block which pritty much only cares about the centre.

i would think id be better off with shallower channels to get the velocity up .

i dont have a very good W/C system so everyone should get better results than i do.

it's gonna take me a while to make the top for this thing

 

Personally I think it'll work pretty good it's roughly the same design as a lot of the professional TEC waterblocks. Only difference is it's made of copper

Thanks you can stay

i might have to make you one with all it's corners

i can't stop looking at it .. it's so nice.

The cold plate is on the mill right now ...

 

Sweet

, Keep up the good machining (at some point I'm going to get a mill too).

 

Here's the cold plate. mostly finished

 

Hey it's looking good!..

..Your right if you keep the lower part shallow it should up the velocity a little.

Can you not get a little piece of Delrin there to make a top? It machines really nicely. HDPE might work to though, all I've ever done with it is drill and use files to shape it, but it didn't burn with a drill bit so maybe a mill will work to.

Delrin is 4 times the price of HDPE here .. so it's completely unrealistic when i have to buy it by the square meter.

HDPE is an "engineering" plastic and can be machined.

However

im gonna see if i can make an acrylic top for this thing now. as i would really like to beable to see the inner workings of the block .. Im sure this will be a bad idea though cos of how flexible acrylic is .... so im sure im wasting my time.... it's all learning for me though

 

dont forget the cutting fluid when doing acrylic, and take it slow.

maybe these pics will give you some more ideas
obviously you'll want the large stepped one.

o yes the cutting fluid and coolant system is MOST important in getting a good finish with anything..

nice pics .. thats a lot of bolts !

 

yeah, i love bolts...

for TEC i'd just make those longer and use nuts to secure the cold plate to it.

and yeah, if when i ever get/build a mill im definately gonna do something with recirculating cutting fluid...

the cutting fluid has BEEN a real pain in the but..

theres always _SOMETHING_ being a royal pain in the rear...

Ouch a whole square. I hate to say it but you all need a flea bay there. This guy ships world wide, it would probably be to expensive to NZ but you might want to check it out. He's always getting in odd sized lots that he sells pretty cheaply...Delrin Virgin white sheet 0.375 x 6 x 27.75 CNC (3.3F)

A o-ring would be good with acrylic if you can cut a groove for it.

If you end up using HDPE or Delrin automotive water pump gasket with a little red Permatex on each side makes a real good one shot gasket. You can get short rolls of water pump gasket here at the auto shops for a couple of dollars.

i of cores could make it out of copper but that would add 1/3 to the cost and weight .. but i bet people would love it

 

weight for the 2 blocks is 620 grams
