I need help to make this part

Other image

thanks all of you for your advice..

I think the sketch is the hard part...
This is a screenshot of what I did:

BTW, I made an assumption that the width is between the mid-points of the 3rd arc (whose radius is 1818).

i stuck

Trying to figure out the original drawing. We have to assume the curve in the side view is circular since no Radius dimension is given. But is that surface cylindrical or spherical? The two centerlines in the front view might indicate spherical

What part do you need help with?
This looks a lot like a homework assignment.
You may get some good assistance if you post the work you've already done, and identify the area(s) where you are stuck.

Attached is an image of how I read the drawing.
I also attached an image of the base sketch. It is very similar to what Yahya posted, but I made a "box" to help contain mine, but it is not needed.
