The first rebuild step is to install the constrictor, first by pulling it over the entrance end. Here we are putting the hose tubulation at the entrance end as is typical, it could be on either end. The constrictor is nothing complicated. It is just a section of liner material which can be the same size or a bit smaller than the liner which you will install inside it.

In this case the constrictor material has been turned inside out before attaching, so when folded back it will be right side out again. This is an attempt to get the fold in the liner material as inconspicuous as possible. This liner material has a sharp fold due to being stored flattened out, and the resulting crease must be taken into consideration.

After folding the constrictor back into the housing, make sure it is nice and even, very well centered in the receiver opening. This can take some fiddling to get all lined up but is worth the time. If your liner has been stored with cornstarch, you should rinse the cornstarch off the the material you are about to use, and dry the latex. The cornstarch is a rather good dry lubricant and if the latex is powdered you can end up wrestling the slippery stuff around versus having it stay where you want it.

You might also note holding the receiver with the bare feet while sitting cross legged on the bed. I find this very effective as it allows both hands to be used during the step where you stretch the liner material over the tubular housing.

Notice how nice and flat the top surface of the constrictor is. This is what we wish it would finish up as, but as we will see, the end to end tensioning of the liner during its installation will change this shape. However, even this simple constrictor will fight some of the resulting funneling of the entrance shape.
