What A treasure!!! Thanks as always Ken.
The only thing I think we should add is the placements of the tucks,
when,
where and
why.
You need to be able to know
when the panel we are shaping needs shrinking. We also need to know
where to place the tucks we need to accomplish our panel.
For example say if I tuck shrink this depth all the way around several times, what will my end result be.
You will end up with a coned shape bowl,
why is that. It is because we only shrank the metal to one point.
If you were looking for a deep bowl, that one point could actually have been the starting point of a radius. Now we need to know where the ending point of the radius is so we can start our next round shrinking on that point.
This is so hard to explain, for me but it is really not that difficult but if you can figure out where when and why you our almost a metal shaper.
Hopefully someone that has a better understanding and is a better writer will chime in.
