I don't know if I ever covered how I do this, but since this is now my 4th or 5th deff dread, I felt I'd chime in! Prior to gluing the main body together (unless you are past greg, who did this out of excitement, when immediately cursed his excitement) , you would make a pin hole, (i use mini hand dremel for this, with a drill bit that is actually the size of a standard paperclip diameter), then widen the hole with a drill bill the diameter of the magnet you are using.
These two knights (assuming it is allowed in narrative) will fill out the rest of my dread mob, in a way I could never do with the stompa. (basically two mini stompas). It's funny because i don't really have the points to give them guns, so might just go crazy giving them insano looking ork death killer combat weapons! GIANT CHOPPAAAAAAAAAAAAA
Anyway, that is it for this week! Thanks for visiting and all your comments! (FYI, comments may be delayed this week. Will let you know why next week!)
