Fuel Pump
There are a few different parts to this model which intersect. Though again, this never posed an issue for me. I don’t know if that is the correct way to do so, but as are as I could tell it worked fine.
1950’s Phone
With the phone I think you can really see the detail I went through to make the rotary dial. This dial is all made from one cylinder, to which I used the circularise mesh tool and intruded the new faces. With my ‘rising star’ works I have since learnt of a method which could have deleted these faces entirely without booleaning, but at the time I didn’t know this.
