Jeep Cab Corners
Need some advice about how to go about making some cab corners for a Jeep that I'm slowly fixing up. I've made other patch panels for it but these are the first that will require compound curves.
Here are the cab corners - the driver's side looks pretty good but the bottom is rusting from the inside out and the passenger side is gone. PXL_20210505_165337354.jpg PXL_20210505_165350020.jpg I made a flexible shape pattern from the drivers side and then a paper pattern to see where the shrinking would be required. It showed a really deep shrink up the middle of the bottom that I didn't think I'd be able to pull off easily. PXL_20210505_165258717.jpg After going back and keeping the paper tight down the centre of the corner and adding tucks along the sides of the panel instead, it seems much more doable. I only have a tucking fork for shrinking right now but they should get deep enough shrinks for this. PXL_20210510_164716946.jpg Now, should I start with the shrinks or blocking out the 'bowl' of the corner? The material is 20 gauge steel and I have hammers, a sandbag, tucking fork and a small bench top english wheel that is likely only good for smoothing out bumps. Just unsure where to start making scrap.

Looks like you have a FC150 or FC170 there.
Just remember that even though the pattern shows where to shrink, it by effect is showing everywhere else where to stretch. A panel can be made by all stretching and or shrinking too. Usually a combination of the two is easier. I would start by blocking out first and just don't touch anywhere around the perimeter where the pattern showed you needed to shrink. Maybe even start with a gauge thicker so you can do more stretching and not thin the panel too much.

Perfect advice from Marcus.
If you have a hollowing block/stump, you can create puckers with a blocking hammer when it comes time to shrink. Make some profiles of the panel out of 4mm MDF, or similar and mark on the panel where they should fit. Or, alternatively, leave the panel in place and test the new one against it, as you put shape into it, Cheers Charlie

Thanks Marcus, I have some 18 gauge that I'll give it a go with. It's a 1962 FC-150 that's in pretty good shape but has the typical rust issues.
Good tip too Charlie - I made sure to make profile gauges from the intact corner. Thanks!

Results
Well, I managed to knock up a pretty decent cab corner for my Jeep. It's not perfect but it's 98% there and a bit of filler should take care of the rest - I'm very happy with the results.

Good job. I have made bowls with the stump method and smoothed them out with an English wheel. With the flexible patterns, I have trouble knowing where to shrink vs. where to stretch. Nice job on the finish and welding.
Looks good. Dave

Lazze does a really good YouTube vid on cab corners.
