Mr. Tromblay, your RU-vid video on forming a sheet metal reverse-curve just popped into my feed. Yours is the clearest explanation and example on the topic that I have seen. Your understanding and verbal skills are exemplary. I am looking forward to viewing your other video postings!
What method did you use to shrink the rolled over edge on the Corsair part? When shrinking this area does the shape in the reverse change? It seems like it would be similar to the Model A front fender repair I made at the running board area during last year's flock to the shop at Pat Brubaker's (Imperial wheeling machines).
@@williamtromblay6795 that seems normal, for mass production, but I'm not sure how specific the application was, or if enough were made to justify the cost of dies for pressing. Look at a manufacturer like Morgan, where everything is hand formed because production is low.
