Step 9: Glue the legs
Use your "Helping Hand" again to hold on set of legs.
In one hand grip your hot glue gun, in the other hold the second set of legs.
Now liberally apply hot glue.
Wait for it to melt.
I personally like to have the front legs and an angle so that the back of my roach is higher than the front of my roach. How you do things is up to you.
