Not much to show as days were spent finessing the panels while areas were still accessible.
Had a lot of work getting this part of the cowl to match the other side and be even. Above the louvres was concave and then became convex in the middle and flat at the bottom! So I started by hammering out the convex area and reduce the crown some in the middle so it transitioned to the flat along the bottom nicely.
On the side that had too much crown in the middle, I marked the high areas with chalk and then use this crowned hammer to hit in the middle of the skate wheel held on the inside. This shrunk the panel down without an causing oil can.
On the low crown side I use this round dolly and pushed outwards with it hard from the inside while tapping around it lightly from the outside. This raised the crown and got rid of the oil can that the other side had as well.
I couldn't find a hammer like this at the last swap meet to buy so I modified another I got. Extended the head and then welded on a ball bearing.
Another view. Works well for raising small low spots
After tacking the cowl together while clamped to the firewall, I took it off and tig welded it together for the first time. Then laid it over like this so I could planish the weld.
Took many hours over several days but finally got it flowing nicely I think.
When widening a curve like this you have to rework the whole radius from one end to the other.
I doubled the amount of plug welds over the original spot weld count as they were pretty spaced out. Like to keep them around 2" apart.
Had to rework the area where it will join onto the windscreen too. Hope it all works out in the end.
