coolwhip · 01-07-09

well its funny that ira has like a post so similar, but im about to make a pot like the one in his post for cpu.
i was wondering if anyone had any tips, and how could i make the best a bit thicker, than just the thin part of the cap.

You going to do a 2" tube for the CPU pot? Get a piece of 1/4" or 3/8" copper flat bar and use a 2" hole saw to cut a plug out of it. Drill a bunch of 7/32"-1/4" holes in a spiral patter starting from the center, I don't know what the optimum depth would be for them, you know what I mean, from the bottom of the holes to the base. But anyway solder or braze that plug flush into the base of the tube. Thats the kind I used along time ago, it was a friends. It worked OK. If you can get it brazed in place it would be a lot safer then just sweat soldering it in.

EDIT: You'll need to solder a strip around it to for your mount to rest on.

are you saying just bag the whole cap idea, and just use the block?
and when you say do the hole thing, im guessing to give it more surface area? and the way to drill the holes, are you talking about how like some of theme homemade waterblocks look?

Yeah if you just drill a 2" plug out of some 1/4" or 3/8" copper flat bar that will give you a nice thick heavy base, it should hold your temp's better then a thin cap would. You'll need to file and sand it a little to fit in the base of the tube of course, then just braze it in the bottom of your tube.

Right the holes give you more surface area while still keeping the mass. Right just like homemade water blocks, only a little deeper. Maybe someone will chime in on the thickness that you want for your base and holes, that part I really don't know. If I remember right the one i used like that had a 1/4" thick base and the holes were drilled to about half that depth in it.It was drilled out in a kind of spiral pattern with just a decent amount of web between each hole. Then about a 1/4" strip all around the OD that was solid.

would i be able to just solder it, or is brazing it the way to go?

Brazing is the way to go, solder can crack out pretty easily. I bet you could find a little local welding shop that would do it for you pretty cheap if you don't have a oxy/acetylene torch to do it with.

what would cause the solder to crack out, the cold?

wait i was thinking though, will i be able to build it all, buy insulation and everything, all for under 125?

You'll just have to figure it up and see. But you could probably buy a lathe turned one from one of the Polish guys for about the same money, or look around and find a used one.

Yeah the solder will flex with the cold and can eventually crack out or fail.

Making own pot is good idea and I can even you help with that. But it isn't as simple as it seems. At first you need workshop or someone who make it for you. After you need copper pipe and square or round bar. The main problem here is that shops probably doesn't sell you exactly amount which you need. Usually you must buy more and pay more for stuff which you don't need. I don't know prices in US, but I guess that all of this stuff is more expensive than I have in Poland. Insulation and mountings is less problem but also another costs. If you can't do some things yourself, you must pay someone. I don't think so that it will be cheaper.
