Modeling tutorial plus gun roulette model download. I just create this model also makes tutorial for anyone in need: D. Immediately, the explanation step by step. The technique I use is to make sure the position of each spin bullets slots are at the right place (simetris). So it will not crash when used to shoot. Follow the tutorial below

First, add a circle with 12 vertices, because roulette that I make will have 6 slots for bullets. Go to edit mode (TAB) and selection of all vertices are then extrude (E) into the scale method (S)

extrude and scale the circle

Second, make a loopcut (CTRL R) on circle we've created

Third, add the modifier subdivision surface / SubSurf. Set the view to 2 so that the object looks fine. Remove one vertex in the middle of circle, so it looks like the image below

Fourth, still in edit mode, create a circle with Add (Shift A) > Circle. Set the circle into 8 vertices and fill typenya Nothing, adjust the number of vertices in the main object that we created earlier.

add small circle

set the place of small circle

Sixth, selection all of small circle and then extrude and scale into as we did in the previous circle.

Seventh, remove the vertex in the middle of a large circle alternately. So that does not have a big circle face as in the picture below

remove some vertex on the center big circle

Eighth, select all small circle and use spin tool to augment a small circle in a circle. Enable Dupli that each small circle is not connected. Set small circle duplication as much as 5 pieces and set the angle to 360 degrees. If successful it will look like the image below
