Dent filling?????

[Moschops]

Hi Guys 'n' Girls,

I've had a Crupi frame in storage for a while I dug it out the other day to be presented with a nice dent in the top tube 

Super bike Dan tells me you cant powder coat normal body filler as it boils in the baking room.

So the frame needs to be welded and ground down 

Does anyone know of anyone who can do ally welding?

give a very nice gentleman on here called Sawzall a PM......he's the nuts at stuff like that

Fill with braze, then file down again back to the original contour.
Not weld, the process is to unforgiving, unlike brazing which does not "pull" whilst cooling.

Can you braze Ally then???

Forgive my ignorance, I did a little metal work at skool but that was a while ago.

Not sure, but I dont think the alloys will "mix" or "take"
And there is an issue as to which has the highest melting point?

Yeah that was my thought.

I think an ally frame needs to be filled with ally.

Braze takes to steel like a duck to water, but I think the ally would melt before the braze.

ally should be filled with ally weld not brazing

[Moschops]

Ok so the question is who on here can weld ally?

It's a bit of an art form i'm told, very hard to work with. just my luck.

Looks like I'll be playing with the P38 and some spray cans, sorry Dan

That will bring back the memories of my first car

Moschops, PM Phil (Sawzall) as somebody suggested. Lovely guy and a genius looking at previous threads with his work.

Or maybe give this stuff a try... I haven't used it myself but the manufacturer claims it's suitable for powdercoating

That looks like just the ticket 

Dan: do you think this stuff would be ok during the paint stripping process? I will have cleared paint around the dented area so there should be no need to actualy treat it directly.

If you have no joy, give me a shout. Think our Snap-On guy does ally welding.

Looks like this stuff is a goer.

will take 205 degrees for 20 mins so can be powdered

I will order stuff and give it a go, I'll take some pics during the process.
