@DaveR, thank you a lot.
You are right, the small size needs to be 5/8″ but the thread stops slightly short by (at normal size) 0.0166″ in radius, and my 5/16″ (0.3125″) was for the radius.
So the real radius of the beyond the thread is (at 1000x scale) 312.5 – 16.6, or 295.9. And I still do not comprehend why I can’t get it to come out. I have actually
attempted, as I explained in my PM to you.But Upright Extruder I repaired small misalignments in the profile, and got both leading and bottom external corners precisely the very same height as the pitch, and precisely at the very same radius.
However could not get the very first 2 sections to line up, developing a surface area border problem in between very first and 2nd turn.
Still, thanks to you and @mihai. s I have practical services for the rounded profile, and I have actually handled to draw one myself with an easier straight edge profile.Intersect puzzled why my illustration simply does not work precisely, and the
deals with will not supply a leading and bottom.
I’ll have another go later on today, going back to square one, and being EXTREMEMLY cautious to get whatever precisely lined up.(*)
