I have a block that prevents the lever engaging the canopy from going down too far.  If this happens, then the fingers that hold the canopy in place begin to retract.    I did my best with the threaded rods on the ball joints to minimize this as well as other adjustments, but ultimately I wasn't able to adjust the level arm so that the fingers were fully engaged when the arm was all the way down.

The block allows the lever to go over center and then stop just as the fingers begin to reverse direction.

Subject: [LML] Re: Legacy Canopy Problem

When this topic came up long ago, the description sounded like the latch and striker were not engaging correctly.  This could indicate a design issue, a construction issue, or even just an adjustment issue.
I do recall during construction of the latches on the 360 that the fit of the actual parts did not exactly match the layout in the plans.  If one were to simply attach parts per the schematic, the latch would not fully engage the striker.  This could have easily led to the canopy popping open given the right flexing of the fuselage etc.  Some modification was required to match the intent of the design.
I also have a means of pulling down on the canopy at the top center of the roll-over.
