Hello there,
Is there any way to repair a broken wheel flange the engine jumped of the track and chipped a piece out of the flange about 1cm.
Help please.

Erk!! You could either built it up with oxy/acet & remachine or you could silver solder the bit back in place if you have it - either method would require dropping the wheels out. If you are going that far I would suggest machining 'em flat & shrink fitting steel tyres.
I've seen locos running around with substantial chunks of flange missing with no apparent ill effects

HI John
You don't say if it is 5" or 3.5" but that doesnt really matter. Machine the tread of and shrink fit a steel tyre on in its place. In fact while you are at it you might as well do them all. Some people think it makes a big diffrence to the traction of an engine some dont think it makes any diffrence.
regards
Andy

Same thing happened to my bantam cock some years ago, i dropped the pair of wheels,
turned the flang off just below the tyre and a little wider than the flange,made a ney flange(steel), pressed it on , along with a touch of loctite,returned the wheelto match the other side, put the wheels back and they are still there 7 or 8 years later . aND THE LOCO IS STILL GOING STRONG,(MORE THAN i AM!!)

If its not too big a lump missing you could build it up with weld (usd a specialist cast rod bit pricey but worth it) then re machine

If it's a middle axle wheel that's damaged, dare I suggest that you might get away with machining the flange off all together, (and its mating wheel flange on the other end of the axle). Or at least machine off just enough to get rid of the missing piece.
There is an argument which goes along the lines (excuse the pun) that only the leading and trailing axle flanges act to centre the loco on the track.

Re building up flange with weld.This is a job that is harder than it sounds.Even with special C.I.rods.cast iron must be red hot before welding,or the weld will just crack out again.Been there ,done that,on a scarifier hand wheel for a friends steam roller.There is a specialist firm nearby who does a lot of this type of work(C.I.welding)and they charged me £25 to fill in some pourosity in some 5" gauge driving wheels.To save me a bit of money they did it at the same time as another job.(The wheels were a freebie,so couldn't send them back)

Yes, I forgot to add the bit about heating the casting, funnilly enough I repaired the cracked scarifier wheel on my steamroller and I've done some loco wheel flanges as well, no problems with either so far and I did'nt get the bits 'red' hot but then I'm not an expert cast iron welder.
