Cut a 1" diameter solid aluminum rod to adapt eight-button Tosten control stick to XenosB. https://www.steinair.com/product/tosten-cs-8-aircraft-stick-grip/
Cut the 1" x 12" solid rod to five inch length with an powered hacksaw. The one inch diameter was too large to pass through the three jaw mini-lathe chuck leaving several cutting operations unsupported. Don't like the lack of support, but... Trimmed solid rod to length with a couple parting tool cuts, cleaned ends and cut a small hole for tail-stock support. Drilled a 7/16" hole through the piece. Opened the bottom end of the adapter to enable a bolt to pass through along with with the ten conductor wire bundle.
Will need to drill and tap adapter for set screws to lock in control stick as well as drill and ream the bottom for connection to the control stick angle.
HAT switches will be wired as pull-up inputs to control the iEFIS screens, the other four buttons will ground the inputs for microphone and other, to be determined, inputs.
