so i ended up making a vanguard unit out of my left over marines but i didn't have jump packs for them, so i set about making them. I have for you here a short tutorial of how to make your own:
a papermate ball-point pen, its cap, some plasticard and of course...
probably the most important step, REMOVE THE INK!
slice off the bottom nub of the pen about 3/4 the way up
slice off the top of the cap about half way in the middle
line up the pieces like they would be if they were still attached to the pen and insert the bottom into the cap so you get something like this:
take the plasticard and cut a small band to fit around the "turbine"
Glue it on and secure it tight (as you can see i used a small binder clip which worked nicely), and you will get something like this:
Repeat the process again for the other side and glue onto either side of your marines old back pack and viola:
one jump pack for your assault marines, or raptors or whatever else, add other decoration as you see fit
and all that for under a dollar a jump pack (with only a mild amount of work), better than buying the bitz any day
C&C as you please
