heatercore connections

[IM [H]ard]

Ok, I just got my heatercore from autozone, which sucked. The people there will do anything there to make you seel bad, ohh well.

Ok, about the core. Is it normal to see corrosion on it new? Just curious, now the real question: How can I get the hose barbs on it? The tubes are ovalszed on the core, otherwise I was going to solder them out and thread the barbs in place.

I'll get pics up of it tonight...later

edit: It just occured to me that since it will be painted anyways, I could just modify the end of the pipes to make the barbs fit on somehow, I really don't see any other way to do this right now...

on a side note, where can I find brass barb fittings more easily? I went to menards(only plastic ones), stein mart(brass but not the right size), and fleet farm. But even fleet farm still didn't have a brass female one...later

I solder the barb or use five mins epoxy.

When the hole is oval, I use my dremel and mod to an oval shape the NPT sides of the barb.

I was going to do that, but they are ovalized, as in, the outer edges of the oval of the hole are larger than the edges of the npt sides of the barb....

Thats why I sometime use Five minute two part epoxy. In 5 mins it's pretty solid and fill greatly the hole. Let it rest for 24hr for best result.

I would use a stronger epoxy, it's more likely to resist the effects that water sometimes has on polymers. Something that takes a few hours-a day to cure, like JB Weld.
That being said, I used cheap quick-curing epoxy on my heatercore barbs... but I still have that nagging worry in the back of my mind.

what kind of heatercore are we talking about here? make and model? gimme a pic of the fittings.

 

[Giblet Plus!]

How big are the fittings? Are they flared to 3/4" or a true 3/4"

You shouldn't have too hard of a time fitting 1/2" ID tubing over 5/8" heatercore tubes. If one of them is 3/4", you could just buy 5/8" ID tubing and run it straight from the core to the inlet of your pump (good for pump performance).

1/2" barbs suck because they have a true ID of 3/8".

Mine's a chevette heatercore, the barbs are nylon of varying reducer sizes because the two original barbs were different sizes. I just stuck the properly sized ends into the heatercore's barbs, epoxied them in place, and had 1/2" barbs sticking out. I'll try to find a picture later, I have to go to class in a few.

damn, I really hate epoxying, but I really like the Bonneville heatercores. So alls I do is just screw em in place and epoxy them down?

No threads, the ones I used were barbed on either end. One end gets covered in epoxy and slides into the core's copper tube, the other end sticks out and accepts the tubing.

even better

if I send someone a heatercore will they barb it for me for like $5?

$5 will buy you some JB Weld at the Ho(m)e (De)pot. Aren't you all about DIY/custom? ;D

It's a good experience, i just did mine 2 days ago... For the chevette heatercore i bought a 1/2NPT fitting and cut down the 5/8" barb and jbwelded the fitting OVER the pipe. The other pipe i did the 2 sided adapter trick, i'm leak testing/assemblign tonight > We shall see

Yeh I am about the DIY, but I still dont have the confidence to make my stuff completly yet...maybe ill grow some balls and just do it when I get a heatercore...time will tell....

It's no big deal, haven't you ever used glue before? That's pretty much all there is to it. Just make sure you get enough epoxy in there to seal it up nice and tight.

No worries, i felt the same way 'til 2 days ago
JB weld is pretty thick, i bet you'll be fine working with it

yeh of course ive used glue im just afraid theyd get knocked loose in the future, or wouldnt be 100% tight, stuff like that...more doubts in my own ability than an unwillingness to do it...lack of a core isnt helping either

 

[weapon--]

^which core do you want? the bonneville core? are you sure you have enough space for it?

what sized inlet and outlet?
1/2" brass fittings?
want permanent fittings?

send me a PM.

 

[IM [H]ard]

man, I'm looking somewhere to host pics for me, theforumisdown isn't doing it anymore, uurrgghhh...later

 

[IM [H]ard]

agghh, I can't find anywhere anymore, but I'll do it the way allready mentioned. But with a variation. I will get some smaller barbs, and tap the holes(There will still be holes left on either side of the barb, and jb weld the suckers...later

[IM [H]ard]

I got back to my heatercore today, and man, this stuff is hard as steel. I have never used jb-weld before, but I plan on it now, heh...later

i felt like that the first time i powered on my computer with my custom waterblock on it (especially because i hadn't watercooled before)

i was going to suggest silver solder from radio shack. i used it to seal my blocks. works pretty well if you get enough on there. just make sure that when you blowtorch it you don't get direct heat on it or it leaks (learned that the hard way luckily my motherboard survived, but it may have taken my memory now)

good luck.
