What is the orientation of the dowel pins #4 and #5 in this schematic?
There is one hole out of the 6 that does not get a dowel, witch one?

there are 2 different part numbers and 6 pins in drawing #4 discription says 1 pin #5 says 5 pins

 

The single dowel #4 looks fatter that the others all #5

 

Got it thanks.

 

There are 6 pin holes and 1 for the dowel. That means 1 hole is empty. The question, what hole has no pin in it? Who has one to look at?
