hi is there a simple way to make bits with a 1.2 mm wall thickness?

Use Joint Push/Pull for that.

Or you could use Offset on the top and bottom edges of the tapered section. Then use Curviloft to generate the faces for the inner surface. Just work on the tapered section. Once you have the faces on the top and bottom you can extrude them with Push/Pull

BTW, make sure all of your faces are correctly oriented. You have a reversed face on the bottom. Also reset the model axes and move your model to near the origin.

hi Dave
I've been trying what you said , and I'm getting some weird results with P/P. I also tried another way by selecting the outer circle and rectangle then curviloft, then the same with the inner circle and rectangle, but got a conflict on the inner and outer skins

Do you mean with Joint Push/Pull?

Which Curviloft tool did you use? I drew in edges between the rectangle and circle to divide it into four quadrants and used Skin Contours on one quadrant at a time.

@Dave-R yes joint P/P , not playing nicely , I select the whole surface but only a part of pulls out
, the inner skin seems to be coming through the outer one
I used the first curviloft , the head that's split in slices
ill try your idea with the lines
