Canopy Actuator - Part 3

The rear handle was mounted onto M6 high tensile hex head screw. A single AN4 washer is fitted with the bolt treated at the base with Loctite 263 then assembled. The external rear unlocking handle will not be installed on this aircraft. 

The front handle requires a short length off M6 all thread rod supplied to accommodate the internal and external handles. The rod was fixed into the external handle with Loctite 263 creating a specialized bolt that is then fitted into the actuator bar with Loctite 242 thread lock to allow normal removal with the internal handle is fitted at the other end

The bolt and threaded rod engage's for full depth off the tapped hole's of the handles to provide maximum support for the aluminum handles.

Revised fixing for Actuator bar

The nylon guides for the actuator guides are fixed using M4 stainless steel screws. These are threaded for their full length, a bit of a no-no any load bearing device. As no bolt under 3/16'' can be regarded as structural [say my old design books] it's OK but it was to much for this builder to bear - it had to be correct so he could feel better. 

Modification: A decision was made to enlarge the mounting to 4.8 mm [3/16''] and install AN3 bolts with AN970 washers to back up the factory nylon washers at both locks [4 places]. The downside is the amount of wear allowance is reduced by 0.4 mm [0.016''] but this was considered an acceptable compromise.

Center Guide
The center guide has to be fixed with a M4 x 25 mm counter sunk screw. This is required as it's will foul with the mounting off the roll bar. The side frame and the nylon guide were countersunk to ensure that the head was flush. 

The side cover's for the actuator and the matching assembly on the other side cannot be fitted until the roll bar is installed. Three [3] AN3 floating nuts installed on both sides allowing removal for heavy maintenance. This installation required a packer to be installed at both sides.

Rear Spring Stop
More binding was noted again and it was found that the tab that the spring is mounted on had a slight bend. This was straightened but there was still a bind so the bracket was removed and the slot opened to 5 mm with a chain file then lengthen to remove the binding at the base.  It would be better to fixed with a couple of clecos until ready to close.
