I have done things both ways (I tend to glue blind drawbores when I use them….might as well). The pins occassionally blow up when you strike them in…it’s nice to have a second pin ready to drive the first failed one through in that case (make an extra for each 4 you have to place…you won’t need that many but peace of mind is a good thing). No glue is really needed to hold these in based on the compression of the joint. What this does give you is an easier repair should your tenon fail for some reason 150 years down the road…
