Brief Description: Push tubes fabrication- elevator
1. Cut to length the F-840 and F-841 push tubes, Measued and marked for the 8 holes to be drilled in each end of F-841 and 6 in each end of f-840. Inserted the end bearings in place and drilled #30 on drill press and or hand drill as required. Removed the bearings and deburred. Poured primer into tubes and rolled tube to coat the inside thourghly then drained the excess. Left tubes upright to drain completely and dry. BTW, the ends were reinstalled on the f-841 and rivited with msp-41 rivits first and then paint was poured in through the threaded hole. The other tubes end bearing wont allow this.
2. Pulled the controll column parts and drilled to final size as called out on drawing 79. The unibit worked nicely for some of this. The 1/4 inch holes were finish reamed.
