Welding cab gas filler hole
 

I'm planning on welding up the gas filler hole in the cab. I've been told you can't just cut a round patch and weld it in, that if you leave the "lip" on the inside it will eventually show through the paint.

Is this true or am I being punked?

Got me there and I need to do it on my cab. I know that you do need to put some shape in the filler panel before you weld it on. Classic Heartbeat used to offer the preshaped filler panel but I couldn't find it a minute ago. It shouldn't be that hard to shape though.

It wouldn't be that hard to trim around the hole and take that lip out so you can butt weld a patch in though. I wonder if a guy couldn't just tack a piece of metal across it with a hole drilled dead center and use a hole saw to cut that piece out and leave a nice round hole to work with.

you really need to put the year of your truck in the signature line, saves me guessing :D

this is what i did on my 58. cut the patch, lay it on the ground and beat the compound curve in with a ballpean hammer, welded said beat patch in with fluxcore welder. haven't seen any lines in 8 yrs / 36,000 miles

Re: Welding cab gas filler hole
 

Yes, you're being punked. If anything, leave the lip intact; it will make the area stronger and less prone to welding warpage.

Thanks guys.

I'll put the year in too.

I'd think your experts may have laid the patch over the hole where it lapped over the edges rather than fitting it to the hole as Ogre showed. On my old cab where we overlapped the piece we replaced the top (removed the sunroof) rather than but welding it it showed through the filler and primer after a while. That was because we were under a tight time line and didn't have time to cut and fit it as we went nor did we want to remove the seat and interior pieces at the time.

Here are some photos of when I did mine. But welding it in.

This was the first thing I did on my cab when I got back to work on it, feels like a hundred years ago!

Brian, thanks for the pictures.

It looks like you cut the lip out from the cab and then fit the patch panel into the hole.

If that is right, what did you use to cut the lip out? I can see what you used to do the patch.

Thanks.

I used a die grinder with a thin cut off disc. Or I may have used an angle grinder with the cut off disc. It depends, sometimes on something like that it's easier to hold the angle grinder so you can put a finger on the panel to hold the disc better on the metal.

Here is a patch panel I found online.

Thank you.

Re: Welding cab gas filler hole
 

No offense, but if you can't make that patch panel with a hammer and a screwdriver you need to get into software development. :smoke: (Sorry.) Even a complete newbie should give it a try. If you have questions on how, fire away and we'll help.

Re: Welding cab gas filler hole
 

I was gonna say if you need to buy that panel you CANNOT weld it in etc:uhmk:

Re: Welding cab gas filler hole
 

Yep, that is a good start in doing this stuff, Can't get more basic than that! That hole is in a SUPER easy place, it's rounded so it won't warp much if any, it has FULL access, you don't even have to bend over to work it, the only hard part is if you are right handed holding the dolly with the right hand and hitting with hammer in the left hand. If you are left handed, this is the easiest patch in the history of man.

Re: Welding cab gas filler hole
 

Thanks guys.

Brian, I already have my patch cut oversized. Before I trimmed it down I wanted to know about the lip on the inside of the cab, should I leave it or remove it. In your patch you removed it, so I think I'll do the same. Although I was told that it doesn't matter, I think I'd like it better if it were smooth on the inside as on the out.

Re: Welding cab gas filler hole
 

On that particular place, leaving the lip and welding up to it, yeah, not the end of the world. It's not "Joe metal man" kinda work, but it would work and not be horrible or anything like that. But trimming the lip like I did IS the right way to do it. If you will notice it's finished off nice and I could literally finish it without any bondo, it's the RIGHT way to do it. Let me get this straight, I am not going to metal finish this truck, I am not Joe Metal Man, I am going to be covering the truck with bondo so no I am not metal finishing it. HOWEVER, doing it this way, I am a few steps away if I wanted to, so YES it's the right way to fill that hole.

The thing with removing the lip is it gives you a bunch of control. You plannish the welds, it gives you a LOT more control of the repair. If you are MIG welding it, you aren't going to plannish the welds as they are very hard, but you can grind them inside and out and end up with an awesome repair.

Like I said, this is as basic as it gets and a real good like Joe Metal Man Jr. kinda start into this stuff.

I am curious to know why you would need a screwdriver to weld in a patch panel???????????????????

Re: Welding cab gas filler hole
 

[quote=paintman;8358351]I apologize (and I just knew I was going to get in trouble here). I was being too funny. If there were no other tools in the world, I could cut the panel out with a sharpened screwdriver and a hammer. Sorry.

Re: Welding cab gas filler hole
 

[quote=DransportGarage;8358371]Thank God you were joking! I was ready to strip my cab back down and re-do my patch panel the right way. With a screwdriver!:lol:

Re: Welding cab gas filler hole
 

I just figured he was talking about screwing the patch panel on instead of welding it. :D

to adjust the hammer!

Re: Welding cab gas filler hole
 

We're havin' fun now !!!

Re: Welding cab gas filler hole
 

...then you use the hammer to drive the screw heads down below bondo level! It's been done.
