Alternative method that is somewhat questionable.

We used a bicycle inner tube for our shooter this year - not the same as intake but equally difficult to attach.

We used the air method to get the inner tube over a piece of aluminum tube slightly larger than the un-stretched tube. We then rolled the tube up into a ring and removed it then used a 6 jaw lathe chuck to stretch the entire tube at once until we could fit the 4" aluminum drum in the middle of the chuck and roll the tube onto it.

Bicycle inner tube works really well, but you need to clean it with something that will get rid of the powder. We used soap and water before it was on and then wiped with a rag with brake cleaner applied since it eats away the top surface of the rubber it will make it nice and sticky.
