How To Repair Brass Radiator
By Jake Mayne on Monday, January 30, 2022 - 07:49 am: Hello all, My '14 T speedster ( the yellow one ) has a drip leak where the top tank attaches to the neck. Information technology appears to have been repaired before. I am going to attempt to solder repair it myself. Seeking soldering advice.
My thought is extremely low heat using flux paste and acid flux solder. Anyone take any experience repairing a brass radiator with solder?
Any advice aid appreciated.
By Andy Loso St Joseph, MN on Monday, January 30, 2022 - 09:04 am: The biggest tip is to make sure information technology is clean, clean, clean. Did I mention it needs to exist clean.
Past Philip thompson on Mon, Jan 30, 2022 - 09:24 am: you demand a big high watt soldering iron the thought is to heat and solder the expanse needing repair quickly.
with small depression watt irons it takes also long to heat
the metal and the heat travels making areas that are
good pop loose.philip
By Rich Bingham on Monday, January 30, 2022 - 09:39 am: You lot need a decent solder - non sold in stores ! Modernistic crap doesn't work well. I don't know the best blend proportions.
Hysteria over evil atomic number 82 has fabricated many items useless.
By Chadwick Azevedo on Monday, January 30, 2022 - 09:58 am: As Andy said, clean. I've done this repair a few times. I've never tried an fe and always used a torch. As far as solder goes one thousand sales are a must, buy everything anytime you come across it. Oft I wind up with no characterization solder and then its just a affair of testing. Having it completly apart get each slice coated nicely with solder then position the neck on top and heat it till it drops down (solder on tank will melt) into place. Voila
Past keith g barrier Savannah Tn. on Monday, Jan 30, 2022 - 10:21 am: 50 50 or 60 40 lead solder can even so be had. every bit has been said clean, clean and clean some more, tin't make solder run up hill so you have to position the radiator to go on information technology level. A pocket-size tipped jewelers torch works well every bit y'all can keep the estrus where you need it, acid flux/cleaner can be purchased at almost welding supply stores. Good luck, a skill worth learning. KGB
By Rich Bingham on Monday, January 30, 2022 - 10:49 am: Ah ! lx/40 thank you Keith. A torch is all-time, but tip size and flame command is crucial. Solder won't run uphill, but heat will depict it. Practice first, y'all don't want stuff coming undone while you fix one spot. Wet rags make a fairly expert heat-sink. Good luck !
By Mike Garrison - Rice, Minnesota on Monday, Jan 30, 2022 - eleven:00 am: I'll echo Rich Bingham's communication. I'll add another emphasis on cleaning the surface well. A wire castor or when accessible some emery cloth should work for cleaning. I adopt paste flux. Liquid volition piece of work just paste isn't as sloppy. I purchase 50/fifty and 60/40 solder at the local stained glass studio where I used to work. The well-nigh important matter to learn is to command the heat. I use a torch. Practice on some scrap showtime. I agree with Keith, information technology'southward a good skill to acquire. Good luck, have fun.

I have been weighing what to do with it. I may transport it to Brass Works.
By Allan Bennett - Australia on Monday, Jan 30, 2022 - 07:thirteen pm: Jake, my radiator man would remove the outlet from the tank, so the two surfaces can be completely cleaned and re-tinned. This is essential, especially if your outlet is an original bandage iron one.
I have replaced an iron ane with a contumely casting. Both surfaces were tinned and the outlet then bolted in place with i/8" brass metalthreads. And so more solder was flowed into the joint using a minor flame oxy torch.
Hope this helps.

By Gene Carrothers Huntington Embankment on Monday, January 30, 2022 - 07:25 pm: Here's a different idea.
I constitute my newer 8yr old brassworks tank had a crack about 1 inch long extending at bending away from the inlet fitting that is soldered to the bottom of the upper tank probably acquired from the extremely rough ride down the 605 frwy at speed recently.
I super cleaned all the coating from the area around the fissure with a wire cycle on a dremel and then sanded it some. Likewise cleaned with some Naphta. I cut and carefully fitted a piece of brass shim stock to closely fit around the neck and cover well past the scissure under the bottom of the tank.
Using the Permatex Ultra Black I coated the shim stock patch and practical it to the bottom of the tank letting it cure, Then applied another glaze over the tiptop of the patch. Applied a glaze of pigment to area and did a test bulldoze. It's not easily noticeable and will flex without cracking. The shim stock gives the adhesive some strength as well.
I was scared to endeavour to do whatever soldering crusade without feel you lot can easily get into lots problem at other joints close past.
I've done this same repair on a freeze crack on the side of the block years ago with continued success.
By Chris Landry, Hudson, NH on Monday, January 30, 2022 - 09:54 pm: On line stained glass suppliers such as Delphi Glass carry both threescore/twoscore and 50/fifty solder.
Past Les Schubert on Tuesday, Jan 31, 2022 - 11:10 am: Factor's "lap type" repair certainly has merit. The merely other solution that I've had success with for a "butt joint" repair is real argent solder. Unfortunately information technology is much hotter, so it will melt/loosen any atomic number 82 solder joints near it. For a exposed item where "cosmetics " affair, it is worth because, as the joint repair can exist virtually invisible.
Withal a radiator neck may non be a skillful practice project,or perhaps it is, equally if the results are unacceptable, then a new neck can ever be bought and installed !!
Merely some thoughts. These things can be practiced wintertime projects
By Craig Correll - Carlsbad CA on Tuesday, January 31, 2022 - 01:33 pm: Jake - I did a repair on my brass radiator two years ago and information technology has held up fine. Note yet, this was not in a location that was cosmetically important. The thread with photos is at: http://world wide web.mtfca.com/discus/letters/506218/518895.html
The central for me was CLEAN CLEAN Clean, (I dewdrop blasted the area), Johnson's liquid flux, and forty/sixty tin to atomic number 82 solder. I used a manifestly old propane torch held well dorsum from the piece of work and several practice jobs before the real deal. The solder should wick up into the joint.
twoscore/60 lead & Johnson's liquid flux can be gotten from stained glass suppliers on the internet.
Past Jake Mayne on Wed, February 01, 2022 - 09:12 am: Thanks all for the guidance. Much appreciated.
By Dallas landers on Midweek, February 01, 2022 - 11:52 am: Liquid cleaner can be establish where the sell copper for roofinf or gutter. On a restoration of 1844 house I used the reddish flux to solder all seams on gutter ,valleys and apartment roofs and cap. Worked well to clean copper.
By Jake Mayne on Fri, February 24, 2022 - ten:01 am: Here is an update. I gave the soldering "pooling" technique a whirl. Special ordered in the Johnson Flux from a stain drinking glass suppler on the due east coast. Rad leaked worse in the same spot. Found a rad repair shop in Pine Urban center, MN 25 miles north of me. Stans Radiator- i of the last radiator repair shops effectually our surface area where "old school" radiator repair is even so a thing. While Stan passed abroad a few years agone his family still operates the business organization and his nephew has inherited the skill set. The cast cervix was too disintegrated (pin holes) upon his removal to repair so I ordered a new one in. He properly repaired the radiator and performed an air examination at 4lbs. Rad is back on the T and hoping to road examination tomorrow (Sat).
Past Wilf Bradbury on Friday, February 24, 2022 - ten:47 am: On this line of idea, I assume the stress in this area of the rad is due to the very short slice of rad hose connecting the engine caput to the rad.
Has any 1 tried to apply a more flexible piece of hose/and or cutting back the necks to requite more space for the hose to flex, thus reducing the stress on the rad neck??
I've run into the aforementioned problem and I've plant a slice of silicon hose, which is quite flexible, to use which I hope might reduce the vibration to the rad.
