Need help designing diff cover.

Anonymous — Thu, 30 Aug 2018 22:11:19 GMT

Looking at making this diff cover. It is similar to the one in the picture. I am working in sheet metal because I want to cut the entire dome piece out on a cnc plasma cutter then bend it with my finger brake press.

The Issue i am having is filling in the gaps. I know they all need to be flanges so i can properly unfolt it, but can't get a flange to stretch the complex geometry.

Should I try designing this in another way such as in models?

The real part image you posted is 2 separate pieces of sheet metal and a separate blank for the drain plug.

There is a flange piece with the bolt holes, and then a folded piece that flares out around the diff.

I agree, but I am having trouble making the upper part that wraps around., not the flange.

I'm trying to do the same exact thing with a Ford 8.8 diff. Was there any solution to this as I'm stuck in the same spot.

Try it like this:

Yes that's what I ultimately am trying but it is rather difficult to acquire the angles and everything that is needed.

Start by making a solid model. This will give you the necessary angles and sizes.

What tool would be best for a solid model? Lofting the corners doesn't seem to work.

Here's a crude screencast showing one way to do it. Another way would be to use the loft tool.

Thank you for the video showing how you did things. I'm working on it and will report back if I can make things work.
