Mr. Tromblay, your RUclips 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!
Wow, just brilliant explanation. Just gotta spend the time in the workshop now practicing what youve jsut passed on to see if I can get the results. As you say its not enough to just watch and learn but your video certainly makes it much more understandable. Keep them coming and cheers.
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).
Gauss (1777-1855) and Riemann (1826-1866) would be proud of you for "A reverse curve won't hold water." They called it negative curvature. If you draw a triangle on a reverse curved surface, the angles add up to something under 180°. On a sphere, they add to something over 180°. The Gauss curvature is 180° - sum of angles, negative for reverse curvature. A horse's saddle has negative curvature. Also, parallel lines are not unique.
@@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.
A very nice, clear and concise demonstration. I look forward to seeing your channel grow.
Enormously helpful - I now understand things that I didn't prior to watching your video. Thanks Bill!
Glad it was helpful!
Thanks for this Bill great information. Cheers Dave from Australia

Thank you for the note.
This was so well explained thank you very much I’ve been binge watching your videos. Thank you for spending the extra time making these.
Thank you for watching
That was excellent! Thank you!
Thank You for sharing your knowledge . I’m looking forward to watching all of your videos. Thanks

Great demonstration Bill
Absolutely fantastic explanation Bill!
This is the first useful demonstration I have seen of how to make a reverse-curve - thank you!
Your welcome

👍🏻👍🏻
I like your tutoring style👍
Another great video- thank you, Bill.
I'm so glad I found your channel, I really like how you simply explain a difficult process...
Glad you enjoy it!
Bill, enjoy all your videos. Thanx for sharing all the information with us.

Hi, I had not heard of that, but makes sense. I will have a Anti-clastic video coming up soon. Thx Bill

Thanks for the informative video . Not sure a "punishing hammer" though. Planishing hammer maybe?
Not sure that I ever said Punishing hammer, I only ever say Planishing hammer.
@@williamtromblay6795 I misheard, sorry.
Well done Bill!
Hello from Racine Wisconsin!!
Nice to hear from you
Do you do any work for the trolley museum?
Hi, I can hear it from the hangar but I don't know anyone over there.
Were those panels stamped to shape or hand formed at the factory?
I would guess that they were stamped.
