Patching sheet metal

[Half-fast eddie]

Working on an old corner brace, getting it back to nice condition. It’s a MF 502 (i think) and based on the style it’s pre-war. It was nasty when i got it. The part I’m asking about is the gear cover.
.

When i got the covers off, first i found that they were secured with 4 different kinds of screws, so obviously they had been off previously. Then i discovered that one of the gears was secured with a nail rather than a roll pin, and apparently the nail had rubbed against the cover, and wore a hole in it. I want to patch it good enough to keep grease in, and dirt out.

Braze it closed.

 

[Half-fast eddie]

Great idea. How do you braze?

 

[Dagny]

braze silver solder might even try stay brite jb weld

 

[ChefRex]

A little smuts such as Marine Tex or JB Weld should work if you don't have the capabilities to solder or braze.

 

[The Cobbler]

braze would be a good choice, but to go unnoticed a tig or mig repair , ground down would be the ticket . maybe you can find someone to do it for you? since you don;t have the equipment

I find JB Weld works great in situations like that. No danger of melting and damaging the original part, and it can be filed down or removed if desired in future. If you're intending to paint over it then it won't show anyway.

I can solder, i do stained glass. And i’m naive enough to try brazing. I had thought about a “steel epoxy”, and since it's mostly for show it could work.

That's the type of repair I'd throw some JB Weld at and not worry about it. I recently repaired a Wolf kitchen hood switch with JB Weld and a set screw collar, like a drill bit depth gauge. Too bad Radio Shack wasn't around or I'd hit up their knob selection. Anyway, when I found out a Wolf replacement knob was $15 I said, "no-way am I paying that!" Yes I'm a curmudgeonly cheapskate. The OEM switch knob is all plastic, with the 'chrome' flashing on it, and a spring steel clip on the barrel of the switch knob, to keep it from splitting for several years.

That looks like a perfect case for that 'welding' rod you see on pop-up internet commercials where they use it to weld all sorts of things together, like three padlock hasps to a rod, which is then struck against a metal surface repeatedly, all the work being shown like the worker just drank 10 cans of Red Bull. Stand back!

That's the kind of repair that would have me turning a punch and die to press a new one for! PM if you want a new one

Brazing will warp the **** out of something that thin.

Not using a "000" tip ( minimal flame) and very clean metal. Zero warpage here......

Is that the type of project for a novice ?

Aren't Wolf applicances crazy expensive?

$5000 smoke sucker... hellllll naw, I ain't spendin 15 dollhairs!

With some practice. Brazing is a relatively simple process, one step up from soldering and silver soldering.

Why not just use plumbing solder? Alot less involved and there's no strength requirement in that repair.

a little dab of shoe goo

 

[Half-fast eddie]

Too late. Appreciate all the advice and comments. I used jb weld, it’s doing fine. I don’t like the color mismatch, but it works.

You can solder it closed, odds are it would look like an old repair.
Best is to TIG weld it as the repair can be invisible.
Silver solder is easy, you can even silver solder using you gas stove
