How It's Made Copper Brass Radiator Brice Thomas Radiator


hey y'all call me tip from an

international headquarters of Scotty DTV

but I was down with Bryce Thomas

radiator and I was talking to Chris

about the old copper brass radiators the

way they used to make them old-school

and Bryce Thomas still does that the

whole of either fix yours or make you a

new one whichever you need and the

process that make them is a little bit

different than the aluminum one I

thought you might find it interesting so

anyways let me get the camera turned on

we'll take a quick look at it Chris

what's the procedure to building a

copper brass radiator well we start out

with our raw materials flat fin coal

copper coal and in our brass sarutobi

tubes the to come a full-length tube we

cut them down to the specific lengths

for that picture job today we're going

to be looking at how a GM cross flow

rate of your core is built GM use these

radiators from the late 60s into the

early 90s on trucks cars almost

everything they built here we've got the

defendant material running on the fin

machine we program that machine to run a

certain number of fans a certain length

and as we as it comes off we'll we'll

stack them up in a box the photography

is a little more delicate than the

aluminum fan so we stack that in a box

and as you see here Beverly's building

this this core she started with the with

side plates she puts a brazing foil down

that helps the first row of fin to line

to the side plate and she put another

coil raising foil down in these

radiators the outside corners of the

weak point they so we put that

additional foil in there just to get her

a good contact joint to the fin to help

strengthen the corners of that so she

stacks this core out once he gets to the

last fan she'll repeat the same process

with the foil side plate and then

strapped it down

now it's ready to to be headed we we

punch our headers out on a turf press

that gives us our tube slot or two


and I know brace Thomas has been keeping

cool cool since 1950 something people

want to follow you to get in touch with

you see your product what's the best way

to do that you can check that on lock

cgj calm you can follow us on our

Facebook page

Ross Thomas radiator and come see us at

a show Chris is Chris is that a lot of

the big shoulders folks and they usually

have a booth and they're all those good

people stop by you see and then Wade

will take that and form the drop steamed

in and put the radius in it that way

when the original tanks go back on this

core the stamp tank separators corners

that way everything fits down in that

channel real nice we get a good solid

breeze a solder joint in that so that

Salters actually coming around the

backside and kind of doubling that joint

that uh here he is straightening the fin

to give it a nice even line at the

header joint and also straightening the

tube so that when he goes to put his his

header on all the tubes line up into the

tube slide after he seats this this

header onto the onto the radiator he'll

take that and rolled the tubes on that

what that's doing the tubes have a have

a tendency to want to close off a little

bit as they come through the header that

rolling this these tubes on that

actually opens they kind of switch fits

it it opens that tube back up so that it

gets a good contact joint with the brass

now it's not necessarily in this step

once it cooks in the oven it's not

necessarily fully being slaughtered

there it does help the header to stay in

place after that once now here we have a

fully assembled header core ready to go

and baked first it goes through a flux

bag all that does is it helps all the

solder to run

the joints so the defender to contact is

its fully connected with the to the tube

using the Salter we loaded on the drawer

to the oven cooks for about three

minutes at 600 degrees when it comes out

we let it cool down then we dip the

headers into a salt but there's two ways

to do that the old-school way to do that

is with a roll of soldering a torch and

it takes a long time to do that here we

have a solder pipe that has melted

solder ready to be adhered or placed

onto the facility the tube header slides

and it's doing both sides at one time

both top and bottom of the header at one

time that gives it just additional

strength you would still do that kind of

the old-school way by hand this just

allows it to do it in seconds rather

than you know thirty minutes so we do

both sides of that the you'll see though

once they pull it out of the solar pot

they'll blow the excess solder through

the tubes that clears the tube then

they'll brush that that will just sweep

away any excess solder that's on there

keeping the tube free and clear after

that is soldered it'll go for a

four-hour bubble test kind of twofold

here we'll using soapy water kind of

scrub any additional solder that may

have kind of bubbled up or Christopher

solidified on the header

we'll use a steel brush and just sweep

that away while that soapy water is on

there we do an initial leak test on it

blowing the air underneath the header

pretty simple way of doing this but it's

very effective we're looking for bubbles

on the top side of that well if we see

any will address that there after that

it goes to a to a final watch and

nameplate warranty numbers put on it and

it's ready to go to

either our radiator shop or one of our

customers ready air shops to be to

recore an existing radiator there well

brother again you know I always

appreciate coming out here and spending

time with you and getting educated on

what keeps cool cool thanks so much for

your time today Chris thanks guy
