I have used a similar method but used liquid expandable foam you can get in hardware stores for sealing up holes. I cascade soda straws together to get the foam at the locations I want pushrod support. The trick is flowing in the correct amount of foam so as not to overdo it. You don't want to fill up the entire fuse and in fact could cause the fuse to burst open. With some testing you can get a feel for how much the foam expands and just get it where you want it.

In my two AVA fuse's and my new Graphite 2 fuse, the most recent applications, I formed three 3/4" discs for each fuse. The front of the boom, the middle, and the rear, just forward of elevator and /or rudder attachments. Cut a notch in each disk to locate each pushrod outer as required by each design. Also in the middle of each disk fashion a notch to be used to orientate the discs as you are installing them to insure the push rods are lined up for smooth action. Shape one end of a 3/8" birch dowel like a screwdriver blade and use the dowel to rotate the disc for pushrod outer location. Don't forget to install the pushrod outers into the notches as you install the foam bulkheads. After the push rods are completed check for smooth operation and dribble slow drying epoxy from each end to fix the front and rear foam bulkheads in place. The center bulkhead should be epoxied prior to installing the front bulkhead. You will now have a very smooth push rod system without any slop or end play.
