Title: Dent filling?????
Post by: Moschops on May 21, 2009, 10:42 PM
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  :tickedoff:

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???? :daumenhoch:

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.

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.

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  :LolLolLolLol:

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  :daumenhoch:

That looks like just the ticket  :daumenhoch:

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.

Looks like this stuff is a goer.

will take 205 degrees for 20 mins so can be powdered :daumenhoch:

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