Using heat to shrink alloy
« on: June 30, 2012, 03:03:45 PM »
Does anyone have any experience and/or advice on this? I ask because today I had a bit of a play with a badly mauled side panel on Albatross 2002. here's how it went:-

This looked suspicious:-

. . . and from the inside by the back seat you can see why:-

Even worse without the paint - revealing a slit and the back of some filler:-

One good thump later out came this:-

. . . leaving this!:-

Out with the panel hammers and dollies:-

. . . . but still a stretched panel:-

Hmmmm . . . . . . . I'd heard that shrinking hammers were pretty useless but I'd also heard of using heat to shrink metal. I read up a bit on the principles and dug out a dual-temperature heat gun on the basis that I didn't have much to lose and, a couple of hours later, ended up with this:-

I don't think that's too bad for a first time effort! ;D

Now you are getting too clever. The damage looked like a classic Albatross injury of a jetty wound. Aloy is great, but it is a little fragile on hard edges. Keep going a lot to do yet  ;D
