You can use the little slender contour guage bars to index the cross section curves.
Say mark every 10th slender finger, and when making the 1st x profile, mark the top of the shovel cross section arcs.
Take the contour section curves at each mark (y).

Hi Brian

unfortunately I use an online translator to translate your explanations ... but most of the time I can't understand without a practical example

How is made the other side ? I have not one at home in the city! :)

I believe that the steel begins flat, and is bent/stamped. The upper part of the steel wraps around the handle, as a "cylinder", open at the bottom.

Yes but can be open in "V", in "U" etc around the handle! ;)

The very bottom of the handle socket "cylinder" is Vee notched. And there is a bottom seam.

Crude .3dm of usage of the physical contour guage on a pretend real shovel curve.

Only one pretend cross section curve is shown (in RED).

I must have 40 or so shovels...

Some idea...you can adapt your surface to any form...

Thanks Brian and Pilou :)

Hi Tony, you could put in some profile curves and do trim and blend. Maybe something like this:

Thanks Michael for your always helpful advice

Hi Tony,
Here's a version:




I can find some errors still, that i would change but it's just an example...

Like when I fillet the join, the fillet runs all the way up the connection, which removes my "wrap" of the steel. If you saw just before that where i cut the shovel base back to meet that part, I think if I did that later, the fillet wouldn't run up like that...

Anyway, just a different look.

Thanks Burrman :)
