Heater Cores?

Takes more heat than standard soldering and silver brazing, and a special bi-metal flux, unless you've got MIG/TIG Arc welder... But why would you be combining AL + Brass LOL!? COPPER + Brass = match made in heaven.

Mine was described as having a 5/8 and 1/2 inch outlets, but its really just a 1/2 pipe on both sides with one 1/2 pipe flared out at the end. Look for one that has copper tubing and tanks if you have a copper WB. There is a product called "copper bond" at Lowes or Home Depot that allows you to glue barbs and pipes together instead of soldering if you arent into that. Thats what I used, its leaktight and rock solid.

Again... those "specialized" Rads and Cores are a COMPLETE rip off. Anyone that pushes these "pretty-boy" water cooling solutions is straight up FANBOY. You do NOT need any of that nonsense to cool "well." Nevermind, I'm not starting this already rerun rant..

Hard to find reserviors made of copper.

Tried it with my torch and it was a nesty looking mess. Definitely not a joint I would ever accept I made a brass "frame/mount" and fan shroud for my '77 Impala HC and need to braze it to the HC. Have to be able to make a perfect braze first

BTW- what's cheap? Never bought the stuff berfore.

What diameter brazing rods are you using, and what type of flux?

My 86 Chevette core has no leaks and it's over 18 YEARS old... try that with some epoxy (save for JB WELD!) DOn't be me wrong, I cannot live w/o my epoxy collection! But for the STRONGEST bond and shortest down time, a quick 10min soldering job is perfect

My $3 bottle of propane has lasted me over a year with frequent soldering/brazing jobs.

The whole kit is about $20 for Nozzle, Propane/MAPP, Silver braze, and flux w/brush!

Plus the torch can be used for other household projects, like making a good Creme Brulee!

Hello all my first post here, main question was where would I be able to purchase that welding stuff.

To me sounds like your using your average cooking torch, one of those small green ones with a small propane tank.

If thats what your using could I just buy that at my local Target store?

Also do you think JB Weld is just as good as soldering?

Thanks for any and all help guys :cheers:

Solder is the best and JB Weld is second in my opinion. I have done both and I highly doubt the JB Weld is going to fail.

Yes you can get one of those soldering/brazing torch kits at wal-mart I think... or homedepot/lowes

JB is DAMN tough stuff, not as strong as a silver solder/braze bond, but close... just takes a good while to fully cure
