Need help with how to make a rim

[ortizwk]

Hi everyone I'm starting to draw in autocad, and i've been trying to make a rim, but i have a problem i don't know how to make the width of the rim, first i did an arc of 3 points from the first circle to de second and connect to the last circle, and after that i did an offset of 1.5 and 2 becase the arc that connects with the angle of 30° is supposed to be 26, so and offset of 1.5 should give me 27.5 and an offset of 2 to the right should give me 24 but, anyway i don't think i'm correct or if the arc command is the correct one to use. I'll attach an image of the diagram, i hope you can help me. thank you very much.

 

I'm using autocad 2014 NO LT

Look at 18deg line using hub centre pt draw a circle 26 radius then using this crossing pt draw a circle 1.5 radius this give correct cen pt for the arms again draw circles and trim. Hopefully this image helps.
