Dovetail myth regarding pin dimensions.



Cutting oil is my blood.
Excellent link, thankyou.
It proves my simple theory of using a rod diameter of 1/3rd of the dovetail depth & also shows how hard it can be.

For the female - I entered S1 as 10 and a rod diameter of 3 which gave a theoretical sharp corner distance of 18.196.
For the male - I entered S2 as 16 ( S1 + 2 rollers ) rod diameter again as 3 with a height H of 9 ( 3x rod dia ). and gave the same distance of 18.196.
Proving that only a rod diameter of 1/3 the depth gives the same dimension over the correct size rollers for both parts.

It also shows this formulae if you prefer...
