SNNC 573 91 . Vintage Tractor Fuel Tank Repair "Gas Brazing"

[@roycarter6235]

99.9 so close to the magic number. I hope that comes very soon as it is well deserved.

Thanks John. On the road to 100k! This time next week hopefully.

Nice one John saved another doesn’t need to look pretty just practical no leaks job done 👍👨🏻‍🏭

[@lagunafishing]

Once its grinded and painted up it'll look like a proper job that should last a few more years. 👍

Just love the ahhhhh! at 17:50 as the tank nearly went over. Must have been all the shit that went into it. 🤣🤣🤣🤣

Ah, you looked into.rhe.tank WITHOUT letting US KNOW....... The depression on the bottom of the tank acts as an integral water separator. If it's ONLY a stationary engine then the fuel cock will provide the segregation, but if it's in motion, then trouble awaits in the lift and injection pumps! PS. ONLY braze these jobbing things with a gas axe, as pinpoint burners are hopeless for full sweating of joints. PPS. Fill the tank FULLY with Kiln Dried sand(available from ALL DIY stores) BEFORE BRAZING.😊 The sand acts as a heat soak and modulates the heat in the parent metals... Keep up the good work. ❤️🤔👍

Thanks John.

Great video John, keep'um coming.

Thanks John

Cut the bottom off a Jerry Can, drill & tap for the petcock, braze 'er on to the top half of the tractor tank (or just use the whole Jerry can with no brazing required) and Robert's yer Mother's Brother 😉

[@BensWorkshop]

Good work!

[@bobdixon6060]

a job well dun

[@bostedtap8399]

Not pretty, but will last a pretty long time John. So near 100K

[@TERRYB0688]

Surprised you didn’t Silica bronze Tig weld it John, nice job though pal 👴🏻👍

[@bantampop3532]

👏👏👏👏👏👍👍👍

If I may offer "An old dog" some new tricks.. That tank looks awfully like a Lister fuel tank(the condensate ponds in the depression formed by the pressed element(lower & upper tank halves). What MANY peeps don't realise is that steel(alloys of iron) ABSORB HC FUELS. Therfore MIG CANNOT drive out the atomically integrated HC atoms from the parent!/filler material(lack of kinetic energy) , which means you WILL ALWAYS get HYDROGEN cracking.... Brazing and better still MAG welding will ALWAYS be "Better" as it drives the excess HC atoms from the parent and those leeched into the filler metal. The other option is soft solder that AVOIDS the. HC parent metal and forms a low temp alloy AROUND the failure zone. From a slightly younger "Old dog" "! ❤😊

[@retromechanicalengineer]

Wise counsel. The plague of hydrogen embrittlement is often overlooked. Also prevalent in non stainless steels which have been subjected to acidic environments.

Not a bad job John but, Jesus Christ, you've gotta give a solid warning about taking an angle grinder to any fuel tank, no matter how old it is. Kingdom come beckons.

I would like to point out that you are ''Bronze Welding'' not ''Brazing''. The two processes are quite different, you sir, as an Englishman should know this, and also not use the term ''Brazing'' to cover everything not ferrous welding as the Yanks do. I too, have been forced on occasion to use those crappy flux coated rods. I don't know what they are made of, but it is low-end scrap melt as far as I am concerned, the only exception being Eutectic brand. May I suggest obtaining some quality bare rods, (1/16'' would be right for tin like that), and a jar of flux? Last forever on a shelf, and always ready.

It's Brazing: The joining of metals via capillary process, a Mechanical Joint, using filler metals (brazing rod/bronze/alloy) with higher melting temperatures of up to 900oc, using a flame torch....Welding is a Fusion Joint.

[@retromechanicalengineer]

Parent metal was not melted, so it is a non fusion joint using a brass based filler. Brazing in my book.
