Trimming the bulkhead to fit the rear fuselage. I cut the large hole in the bulkhead later (having missed that bit..)

Next come guide holes for the torque tube holes. A piece of rigid wire to make sure it is all straight

Bonding in the bushes on the inside. The suspenders are to make sure the tube is parallel to the firewall and horizontal.
Having triple checked everything I was sure the plates were right way round on the torque tube. Not so. Murphy strikes again. Switched round they did not move freely in the bushings, which by that time were fixed rock hard. Judicious use of sanding solved the problem. I have since found out that araldite is easily softened with a bit of hot air and I should have done that.

Once the inside has cured more araldite goes on the outside of the bushing. Here again the peroxide syringe is the perfect tool

To prevent the tubes from sliding sideways nylon bushes are installed on the inside. It is very difficult to get the holes in the right place, so a few mm of play is allowed. I achieve a perfect fit and am very pleased with myself.

As a finale the four temporary bolts are replaced with steel pins. Slightly oversize to ensure a tight fit, they require a very satisfying thump with the hammer to drive them home.
