What ever happened to " a man and his dog walk into a bar..."? Sorry, my principles
required me to respond. Oh, and since Sabrina is taking Quantum Physics
and will need to be up on her Transforms, I submit the following: What is the
transform of the integral from zero to infinity of 1 over the square root of
the variable (cabin)? The answer below in reverse letters...
Do Not Archive (in case I remember Laplace incorrectly and it is actually a Fourier)
nibac gol Now, that's a joke! :-)

You guys are too funny!
When I was building my canopy frame, I was amazed how tinkering with one side would
often release the other side.
I would lock one side, leave the other up. In attempting to lock the remaining
side the original side would sometimes release due to movement of the release
cable. That scared me.
Has anyone else split the release mechanism on the canopy so both the left and
right side need to be released independently?
This way, one has 4 "disengagements" before release, accidental or whatnot.
I prefer this to the single "disengagement" of the 650. Attempting to re-latch
one side necessarily unlatches the other since it is a solid arm. Correct?

Hi Sabrina,
In my case, I left a little slack in the release cables. There is
still plenty of movement when you rotate the control knob to release
both latches, but it isn't so tight as to do the nasty stuff you talked about.
I also got lucky with the placement of the rotating knob for the
release. It fit kind-of tight so when it is nearly closed it takes a
little extra force to "Click" into place. That also means it takes
some extra force to get it started in the latch opening cycle.
Have fun,
Paul
P.S. Watch out for jumping electrons.

When I was scratch-building my canopy, after several iterations I wound
up using two barrel bolts, which I made spring-loaded, to slide over and
snap into two notches in some 3/16 steel t-bar stock. I haven't flow it
yet, but after you release the turning handle, you can hear the barrel
bolts snap in place. I think it will hold.

I have the old style canopy latches. I have never had one side of m
canopy unlatch as I was trying to latch the other. There is a bit of
slack in the cable that needs to be taken up before the canopy will
unlatch. The two sides latch up independently of each other.
If I was going to use the new style latch, I would definitely alter
the design to allow each side to latch independently of the other. All
it would take is slots on one end of the tie bars linking the latch
hooks to the torque tube and springs pulling each hook towards the
latched position.
