People use formers inside of aircraft fuselages to help maintain the shape. Formers can also be used to help maintain the shape of cylinders when making towers for buildings. They also help in the glueing of other parts to the towers by supporting the glue tabs. Measure the diameter of each end of the cylinder and cut formers to fit inside. Holes in the formers help positioning and securing the other former.
Pictures showing the slight tear drop shape without formers:
It does not look too bad now but continuous handling during the build of the model will distort the shape.
Formers:
They are different sizes here because the tower is part of a lighthouse and is tapered. This technique will also work on cylinders that maintain the same diameter throughout the entire length. You could leave one of them without a hole, but if you do make sure the one with the hole is the first one you insert into the cylinder. You can use the open end of the clylinder to seat that former then use the hole to position and seat the second former.
One of the formers inserted:
Other former started:
Note the position. The hole in the first former is used to seat this one.
Turn the cylinder over and use something to reach through the hole to seat the other former.
Second former in position and seated:
Tower with both formers in position:
I have found that this also works with tires on vehicles that have a disk for the outer and inner side and the tread that is a strip with the sawtooth glue tabs. I always had trouble putting the outer and inner disks on the tread until I tried a variation of the technique described in this post.
