John, that looks good, but I think that is the surface that the canopy
seal inflates against. If so, you will probably have to move the spring
or design another method.

Subject: [LML] Re: Lifting the
Legacy Canopy
Here's another approach to lifting the Legacy
canopy. There is no external handle. Instead, leaf springs are
mounted inside the edge of the canopy on either side near the lateral guide
blocks (see first picture). When the canopy is lowered, the leaf springs
contact the fuselage keeping the canopy up about .75 inch (picture 2).
The dimensions and strength of the leaf springs are such that when the canopy
is lowered, the canopy latch can just engage. When you lock the canopy
down, the springs collapse (picture 3). When you open the canopy latch,
spring pressure pops the canopy up about .75 inch (picture 4).
I have not installed the pneumatic canopy seal yet
so there could be some interference. I've been flying with this spring
arrangement for about 2 months now and it seems to work well. I'd
appreciate any feedback the group may have on possible improvements or obvious
drawbacks.

Subject: [LML] Lifting the Legacy
Canopy
Does anyone have any suggestions as to how to install a handle or
otherwise to facilitate the raising of the Legacy canopy? It is very
difficult to get it to come up the first inch or so because there is no place
to get a hold on it.
Pictures would be nice!
