In between aileron and flap priming and assembly sessions, I took some time to start preparing parts of the aileron trim bracket. This involved deburring bracket edges and final drilling holes as well as separating spacers.

| Aileron trim bracket pieces ready for priming |
After priming all the parts I put together the aileron trim assembly as described in the plans, and then used a power supply to verify that the trim arm operates as intended.
 |
| Aileron trim assembly riveted together and bushing/connector inserted into openings |
 |
| Some minor scraping of the primer will be touched up once assembly is complete |
 |
| Upsizing the trim motor attachment holes using a #28 drill bit |
 |
| A cleco clamp came in handy to hold the nut while using a screwdriver from the other side to attach the trim motor to the bracket |
 |
| Trim motor attached to bracket and arm, with wires routed through the bushing |
 |
| Trim motor arm extended to test free movement of trim arm through its entire range. No binding occurred! |
 |
| Cotter pins bent to hold the parts together |
With the aileron trim assembly complete, I took one of the bottom wing access panels and after marking the required location of the trim assembly on the access panel, I clamped the trim assembly in place and match drilled the #19 holes for the attachment screws.
 |
| Trim assembly clamped to access plate in position for match drilling screw holes |
 |
Screw holes were drilled to #21 on the drill press and then to #19 using a reamer. As each hole was drilled to size, a screw was inserted to keep the trim assembly in place on the access plate
|
Finally, I deburred and dimpled all the screw holes in the trim assembly and access plate for a #8 screw, and also dimpled the nutplate attach holes on the aileron assembly and nutplates. The nutplates were then attached using 3-3.5 rivets.

| Access plate and aileron assembly with screw holes and nutplate attachment completed |
 |
| Aileron trim assembly will be put aside for now until further progress is made on the aileron actuation and bottom wing skin sections |
