Dovetail slide - video

Thanks for the comments, I've looked at lots of calculators & methods but none consider the diameter of the pins to be important. By using any arbitrary pin diameter, lots more calculations are required.
If we are able to calculate the ideal diameter of the pins to give the same dimension for the male & female, then everything becomes much more simple to make.
Make either the male or female first - measure over pins - cut mating part to the same dimension over pins. This can be any dimension, so there is no need to split hairs when making the first part.
Fortunately this ideal pin diameter for both male & female is 1/3rd of the depth of the deepest dovetail for 60 degrees & that's it.


For any other angle - ( Cosine of angle divided by [ 1 + cosine of angle ] ) x depth of dovetail = common pin diameter.
