Assure the fuselage and motor are aligned straight andvertical in the opening, then ease in the beam plate into position. Check thefit, remove and make any final trim to fit to the fuselage, and trim to achievethe wanted clearance around the motor. At this point I coated the bare wooddoublers with a very light coat of thinned finishing epoxy to fuel proof them.Allow to dry. With the motor still hanging in place on the jig, position thebeam plate in the nose and make contact with the nose ring and motor mountwithout moving the alignment of the motor, and tack the beam plate in placewith just a few spots of medium CA. Drill the holes for the motor mount andnose ring. Remove the mounting jig and then the engine. Install the blind nutsfor the motor mount and nose ring, place the motor assembly in place andinstall the mount and nose ring bolts. Check the spinner back plate alignmentwith the nose of the plane by installing the back plate, and sighting the gapbetween the back plate and the nose. Then check the engine down thrustalignment by leveling the Allure using the left canopy rail, and check theengine thrust using a thrust alignment tool. If needed the tacks that hold thebeam plate can be broke as needed and re-tacked to adjust the beam plateposition to get the alignment correct. Once it is in place and you aresatisfied with the alignment, remove the motor and secure the beam plate with afew more tacks to assure it will not break loose too easily during the nextsteps of fitting the firewall.
