 |
| JB Weld around the edges to help resist any turning of the Bronze Bushing. |
 |
| Since press-fitting the Bronze Bushing into the angle, the steel bushing that rides inside of it will no longer fit. I had to drill out the hole very slightly, and carefully. Note: I had to buy more Bronze Bushings and start over. Once I put the Pivot Bushing in there it was obvious I had drilled the Bronze Bushing out too much -- causing play in the system. See bottom of page for how I achieved a nice fit (January 2, 2008.) |
 |
| Here it is after being drilled out. I used a 21/64" drill bit. (See bottom of page for the change made.) |
 |
| Here is the "fit" of the steel bushing in the bronze bushing. |
 |
| Until I actuall install them on Rib # 9, they are done enough! Still need to decide whether or not to use primer and oil on the bushings, or just grease. I left the cotter pin off the castle nut until I decide. ON TO THE MAIN SPARS!!! |
| I changed out both Bronze Bushings and totally re-made one of the bellcranks all together ( January 2 & 3, 2007) The holes I had made in the angle was too large. Once you "Press-Fit" the bronze bushing in the angle, it squeezes it together so that your Pivot bushing (which fits inside of it) will no longer go fit without enlarging the Bronze Bushing hole. I bought a Reamer the OD size of the Pivot Bushing and everything fit nice after that. |
 |
| A 5/16" Reamer. |
 |
| The reamer goes in straighter than this. Dad has a natural tendency to "angle" whatever part I am asking him to pose for. :) |
