Default -56 Chevy pick-up fender modification

Hi ,

This is my latest project that I am now slowly making. It is making a patch for a -56 Chevy pick-up rear fender that has a place for sparetyre.And now I must get rid of the sparetyre hole.On this one I doubted myself, the piece looked like crap during the process but then suddenly it started to look like it should.

Some of you may have seen this video allready on my facebook profile.

Starting point

That came out nice!

I made a transmission tunnel, not as complex as your project, but being to stubborn I kept after it and all of sudden it looked as though I knew what I was doing. I don't know if I could ever duplicate it again.

Thanks guys

I know what you mean Keith. On this one I had trouble on visualizing the shape. And the flat areas where hard to keep flat. The Pullmax session went okay but I gotted puckers below the bead. Like the panel would have shrinked just below the bead and in the middle of the curve. Anyways I got rid of them by wheeling with light pressure.

I started to trim and fit the panel.

I cutted off the spare wheel hole cover. Then I started to think how to trim the panel and what to do to the remaining flange. If I leave it , I have no access to the backside. So I cutted off little bit of the flange. Screwed the piece in place and marked backside with sharpie. And then scribed the line. Then I had little bit off flange remaining and then I straightened the flange with home made tipping tool. Then I started to trim the panel.

The part is very difficult to trim cause it has many shapes and big round corners. I want it flush with the fender so I can get a smooth weld. I spended very much time on the trimming but now it is good enough. At this point I have learned that good fit pays back when I weld the part. And since I am gas welding the piece.

Next is time to weld..

Today my plan was to weld the piece. Well , tacking took much more time then I thought and all the time I had went to tacking. Few spots have gap that I cant fusion weld..but I think I am going to be okay. Things dont allways go as planned

my thinking is that always when I have welded the piece I want to hammer and dolly the joint while it is still hot. That is why I will weld the piece next time I am at the shop.

Janne before you get to the welding, grind all the tacks flush on both sides and planish while they are cold. Be careful when you planish and watch how the material is responding. You may may be able to correct your gaps with careful work.

I place a magnet close to the panel I am welding and stick both .035 and 1/16 rod on it so I can use which ever one is needed without stopping. If the hole gets too big just move to the next place you have a good fit and continue.

Go back and catch up with any places that need special care and let everything cool. Grind only excess material away from both sides and planish cold. NO bashing about. Control where you get the movement and where you put it.

Hope this helps get a finished and smooth part.
Good luck
Jere

Thanks for the tips , Jere

I have always just leaved the tacks and melted them during the welding. Now I will do as you advise and grind them flush.

That magnet trick is a good one and I wil use it.

We will see how it goes..
