Hi guys, remember me?, I'm back for this weekend ... at least.
Ok here we go with another HMMWV tutorial

It's turret time ....

Go to the kitchen, and steal something like this ....



That's 6 1/2" diameter...



Now, go to your closer hobby store and get this (0.080" thick, styrene sheet):



Place the plate on top the styrene sheet and draw a circle like this ....



Find the center of circle ... that's gonna be your homework .. . and somebody please, post how to find the center for the guys ...



Next ....



Ok, draw an inner circle, diameter:. 5 -1/4"


Trace a parellel line to the horizontal one, 2-1/2" from center, as shown ...


Now, trace a parellel line to the vertical, 1-15/16" from center to right side, as shown ...



On the bottom horizontal line, mark a dot to right side @ 5/16" from center



On your right vertical line, mark another dot from top intersection @ 1-4/16" downwards.



Use the same plate to trace a curved line between those two dots.



Now, this time to the left side of the first horizontal line, mark another point @ 2-1/4" from center.



Trace a verical line @ that point....



Draw a 60 degrees triangle as shown....



Mark these two sides of triangle @ 1-14/16"


Trace a vertical line from one point to the other ...

And start cutting.
Remember, use a fine sharp tip, like x-acto no. 2



do the outside first ....



then the inside ....



You can use this fancy tool I found the other day for circle cutting.
you can cut up to 5-1/4" of diameter with it.
It won't work for the outside circle though.



Stay tune for 2nd part ....

Cheers
