Lugless BB and Head Tube Specs/Drawing

[FabCad]

Hello guys,

First, sorry about my poor english. Isn't my native language.

I'm planning build a aluminium road frame at all. I don't want to use finished parts.
So, have someone some type of lugless BB and Head Tubes specifications/drawing to share?

Drawings:

- integrated and non-integrated Head Tubes
- BB30 and English Bottom Brackets

I will apreciate for that.
Thanks for your attention.

Cheers!

Thank you, Joel. Very useful drawing.

Would anyone have a similar drawing for the Columbus XCr bottom bracket shell, Columbus code "ZSMJXCR"?
