Just clicked on this video to see that you have reached 100K. As a long time subscriber I wish to congratulate you on reaching this milestone. I hope to see you reach 200K.

[@PetterPJ3W]

I love the handbrake used to clamp the sheet in the bender!

[@roycarter6235]

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

[@thomaswilliams]

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

[@paulp96275]

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. 👍

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. ❤️🤔👍

[@FoxtrotOscar123]

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 😉

Great video John, keep'um coming.

[@zenoelea8239]

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

[@retromechanicalengineer]

Thanks John.

[@paulmorrey4298]

Thanks John

[@bobdixon6060]

a job well dun

[@BensWorkshop]

Good work!

[@crawlstockrc]

Have you tried Tig Brazing with Silicon Bronze rods? It’s my go to for sticking metal now.

[@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]

👏👏👏👏👏👍👍👍

[@nkelly.9]

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.

[@PatriciaSawyer-ot4us]

John Man!. Poxy Arseteline was always better than Poxy Propane for neat brazing work. Please EDUCATE your viewers. DON'T use Tig Gloves with angle grinders. Use heavy duty welding gloves, AND a full face visor. Things happen with cutting wheels that aren't pleasant, like cutting your finger off, or the disc exploding in your face. Thanks. Just saying😇

[@craigywaigy4703]

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.

[@Onan-u3b]

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.

[@65cj55]

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.

[@Onan-u3b]

@@retromechanicalengineer Not according to Audel's book on welding, among many others. The Americanism of ''Brazing'' to cover everything not true welding came about after WW II. Actual history that can be read about. The term ''Bronze Welding'' comes from why it was developed by the British Admiralty, the material used and the fact that it can be built up. ''Brazing'', or hard soldering, is used for contact joining of similar or dissimilar material due to capillary action, similar to soft soldering. Think Esi-Flow or Brass Brazing as used on early motorcycle frames of tube and lug construction.

[@Onan-u3b]

@@65cj55 I agree WELDING is a fusion joint, and when WELDING Bronze with a Bronze rod the joint is WELDED. My contention, IF you re-read my original comment, was that as an Englishman it should be called Bronze Welding. I have already explained how, and when it came to be called brazing. Feel free to explain how to build up material with a BRAZING rod such as Esi-Flo. Unfortunately, without a few hours in my library, (which I shall not do), all my ready reference to this is on an old hard drive. Suffice to say, this has been hashed out in many welding forums, and I stand by my statement that it is Bronze Welding. Please feel free to research the subject, it is an interesting one, but history, and historical terminology still stand. BTW In North America Bronze Welding is also known as Braze Welding, i.e. it is different from brazing. Different material characteristics, different temperatures, different uses.

[@retromechanicalengineer]

@@Onan-u3b P.M Robert's manual, 'Brazing', published by the British Standards Institution and the Design Council of Great Britain was the preferred text book of British apprentice schools, including those within the Armed Forces. He describes 'brazing' as the capillary penetration of the filler metal into parallel gaps between the components to be joined, at temperatures below the melting point of the parent metals. I am happy to concede that 'Bronze Welding' does not have to melt the parent metal, having revisited the chapter. However, it does not rely on capillary penetration, but upon the build up of a substantial external fillet. An Englishman would therefore be justified in calling the process carried out by John 'Brazing'.
