Sliding canopy (cont)
The sliding canopy will require four brass channel assemblies to move the canopy.
In this post two of the brass channel assemblies will be made that go on each side of the cockpit.
See my threads on either building the Yellow AT-6 or assembling the Robart ARF P-47 for making the brass channels.

The 3/16" square brass channels with a groove down the middle is used on each side of the cockpit.
The cockpit width is 6" plus I added 1 1/8" extra (5/8" on each end) on the channel for mounting to the side of the fuse.
A 5/32" square brass channel was used to slide inside the 3/16" brass channel.
The 5/32" square brass channel was cut about 5/8" long.
A 1/8" hole was drilled on one end to house the dubro #181 2-56 threaded ball link (which will be connected to the canopy).
The other end was drilled/tapped a #0X80 hole.
A great planes GPHQ3835 2-56 threaded rigging coupler was also drilled/tapped for a #0X80 hole.
A #0X80 machine screw was then used to connect the rigging coupler to the 5/32" square channel.

The 5/32" brass channel assembly can now slide along the 3/16" brass channel and the ball link will be screwed to the canopy.
Later, a sullivan gold-n-rod will be connected to the other end of the rigging coupler.

#0X3/8" pan head screws used to hold each channel assembly to the cockpit.

The cockpit narrows at the rear but the sliding part of the canopy is flexible so the canopy shouldn't bind when it's opens (hopefully!).
