I use a different approach. I take a length of 1/32 brass rod and cut it into 3/4" lengths. I then use a pen vice with a 1/32" drill and drill a hole in the bottom of a figures leg 1/4" deep and after applying a dab of ACC to the pin I stick it in the foot.
At the spot I want to place the figure I drill a 1/32" hole and stick the figure in.
The advantages I find is that if I later decide to move the figure to another position all I have to do is pull it out of the hole. It also works well when I need to move the figure to work on the layout.
The only caution I suggest is that if you remove a figure and want to reinsert it You best immediately place a small round head pin into the hole or you wont find it again.
The above is based on the almost 2,000 figures I have placed on the layout.
