single to double concave

Does anyone have an illustration or picture of how a single to double concave bottom is suposed to be?

Thanks in advance.

…really hard to photograph for a computer screen on a modern board, but here’s a 1975 mostly double concave [‘bonzer bottom’, Cordingley called it , apparently ??] single fin…

[ By the way, how do you show the photo in THIS box, rather than having to ‘click on’ an ‘attachment’?

anyone… please? ]

check the box that says “inline”. then, click the “insert photo” button (second from the right on the toolbar), choose “select inline image”, and select the image that you uploaded as an inline image…voila.

copy and paste

“copy and paste” …I understand the words, but not the computer concept…[I’m a complete internet goober , or is that preschooler ?]

“jawl na ton mawr”…well, you got me there, mate !! [that REALLY threw me for six, as we say here in oz !]

    even spelt backwards, it still  looks just as scary... 







             chippy

A plain drawing will do fine!

I know where and how the double concave is, all i need to see is where and how is the single concave is single-to-double concave bottoms, and how is the transition from the single to the double concave made!

Thanks!

ahh…sorry to confuse you…your post had me laughing out loud. it’s welsh …very loosely translated as “jeesh what a big wave!”

re the pic thing - I literally copied and pasted this one ie right click - “copy” put your cursor in the appropriate place then right click paste!
